VCD to no-loss Quicktime compatible

[lansing]

Hello all,

Any help would be appreciated. I have 4 vcd cds. Which I would like to convert into one or two dvds with an interface/transitions etc. I would like to convert the VCD .dat files into a format that I can edit. Right now I'm using imovie 4 unless this will not work I can get another suggested program. I was thinking to extract the vcd into imovie 4 supported format and then edit it there and burn it and add the interface with idvd 4. I have been using galactica's tutorial on http://webpages.charter.net/ernsta/SVCD2DVD.htm . To convert the VCD format to DVD usable format. But after going through step 1 to 4 and trying to import the file to imovie 4 I get "Can't open file part1.mpg"; skipping it and continuing.


Any help in extracting the VCD so that I can edit, add the dvd navigation and then burn it to a dvd without losing sound and picture quality would be appreciated.

You cannot import mpeg in iMovie...You must convert it in QuickTime DV or DV stream...You can do it manually from QuickTime or You can try this:

While the vcd mpeg1 standard is one of the legal DVD resolutions, iMovie will choke on it. You need to do a little massaging of the files. Once you have the Part01.mpg (from following galacticas tutorial) use Quicktime Pro (worth the upgrade pricetag) to export the vcd mpeg into a DV stream by choosing File>Export and choosing Movie to DV stream in the dropdown menu. This should be compatible with iMovie and can get re-encoded to iDVD. There will be some loss in quality going from iMovie to iDVD, but it should be negligible.

You also could go the Sizzle route if you have no need to edit the mpegs and wanted a simple menu structure.

PJM,

When I export the Part01.mpg (Movie to DV Stream) to a DV stream in quicktimepro there are a few other options under the options button.

Options

DV Format: DV, DVCPRO, DVCPRO50.
Video Format: NTSC or PAL
Audio Format: Locked or Unlocked
Rate : 48.00khz, 44.100khz, 32.000khz

Do I leave it to the default of DV or does the others have any benefits? What do you suggest?

TIA

[terryj]

go: DV Pro
Locked Audio
NTSC video ( if you live in US), PAL ( if you live in Europe)
44.1 khz audio


I have used these settings and they produce pretty good
streams in iMovie.

[lansing]

Does anyone know what the difference between the following are? Better quality? Better compatibility? etc?

DV, DVCPRO, DVCPRO50
48.00khz, 44.100khz, 32.000khz

also by converting the file from the above suggested settings. I noticed that the new DV file seems to be quite large. Viewing the mpg file in quick time the first segment is roughly 1 hr and the dv file was 4.5 gig at not even half way point of the conversion.

Is my assumption correct that iMovie 4 and/or iDVD 4 will compress the larger DV format? I have other segments that I would like to join into one or two dvds.

thanks again

48.00khz, 44.100khz, 32.000khz

For Audio:
48.00khz, -->CD Quality Best
44.100khz, -->CD Quality Average Retail
32.000khz-->Best Computer Sound Quality, do not use

for Video:
DV, -->Standard everyone uses
DVCPRO, -->JVC standard for higher end PRo Capture
DVCPRO50--> a JVC standard for even greater capture ability at a
higher algorithm to shorter tape in LP mode.

Stick with DV for video, and either 44.1 or 48.1 khz on audio.

Your compressionwill come after you edit all your clips, and then
save to iDVD 4, and then allow iDVD4 the long ( overnight) task of compressing down your files. IF you had DVDSP2 or FCP4/FCE2,
you could use Compressor to handle this.

the rules are 1min of uncompressed DV is equal to 1GB of HD space.
You are making uncompressed DV, therefore you will need A LOT
of HD space. I would get the MPGs edited together first in QTPro,
then export the edit segment out to DV completed, then bring it
into iMovie, finish setting my chapter points, then send off to iDVD4.

[lansing]

Thanks for the insight.

Doing the calculations (1 min to 1 GB) it looks like I won't have enough space on just one storage device. However, I think I can distribute dv stream files to multiple hard drives.

Questions:
1. Can iMovie4 / iDVD 4 or any application (DVDSP2 or FCP4) able to access multiple storage drives for the different file clips?
2. Does the dv stream files all have to be stored in one location?
3. If the dv files can not be accessed in multiple locations, can you bring in segments and edit/compress them to reduce overall file size?

TIA

[live4ever]

That should be 1 min = 200 mb DV video
or 1 hour = 13 gb DV video

live4ever is correct on the sizing.

Questions:
1. Can iMovie4 / iDVD 4 or any application (DVDSP2 or FCP4) able to access multiple storage drives for the different file clips?

yes, drive partions or FW HDS.

2. Does the dv stream files all have to be stored in one location?

no. Just make sure not to move any after you have imported them into
your current project, or you will have problems.

3. If the dv files can not be accessed in multiple locations, can you bring in segments and edit/compress them to reduce overall file size?

yes. Your project however, will be the only place they are reduced.
The original source files will still be quite large.

The file could not be imported: The movie “G4 Speed/Volumes/FireLite 80 GB/p1 - 010213.dv” cannot be imported. It is more than 9-1/2 minutes long, which would be more than 2 GB once converted to DV. iMovie clips must be less than 2 GB in size. You can use QuickTime Pro to break the movie into smaller pieces, and then import the movie in segments.

I've received the following error when importing the dv stream. FCP4 should be able to handle larger files or do I another software that anyone can suggest?

I don't really want to cut all the files into 2 GB chunks.

TIA

When export the .mpg file to a dv stream I get the video however no audio. Is there a reason for that and how can I fix the issue? I can hear the audio when the file is in .mpg format.

Here are my export settings.

export settings : movie to DV stream

options
DV format: DVCPRO
Video: NTSC
Audo Format
locked
Rate: 48.000khz

thanks in advance

Yes, FCP4 will handle the large dv stream.
Otherwise, yes you will be limited in iMovie.

See other posts about demuxing MPGs. Since MPGs are a muxed format
( one stream made of two seperate streams, yet not fully integrated)
you will have to first demux, or split, the MPG back into its elementary
streams, and then recreate the file in a format that fully integrates the
two pieces, such as MPG4 (AVI) or QT MOV. if you are using iMovie 3.01,
I would reccommend QT MOV, using the 3ivx codec, as iMovie will allow
you to import the file.

You can use to demux the MPG the following app:
ffmpegx

select the MPEG file in ffmpegx, demux back to elementary streams.
Open QT Pro 6, open the .m2v ( video) and .aiff (audio) files.
Select all of the video, copy to clipboard.
select the audio, add scaled the video to the audio.
Export as QT Movie using the following settings:

Your settings for the 3ivx codec should be as follows:

Video: 3ivx D4.5 codec
Best Quality
Average Bitrate
29fps
keyframe every 90 frames

audio:
2 channel Uncompressed
48.1 khz, 160kbps

codec available at http://www.3ivx.com

two pieces, such as MPG4 (AVI) or QT MOV. if you are using iMovie 3.01,
I would reccommend QT MOV, using the 3ivx codec, as iMovie will allow
you to import the file.

I don't have iMovie 3 but iMovie 4.

It was suggested in the previous post to convert the movie into a dv stream and then use either iMovie 4 or FCP 4 to import it and edit the file so I think it may be a good idea to keep it in a dv stream unless suggested otherwise.

However, If I convert it to an quicktime movie using 3ivx codec I think there still is going to be an issue of the file size. Previously when attempting to import the movie to iMovie 4 I got an the following error.

The file could not be imported: The movie “G4 Speed/Volumes/FireLite 80 GB/p1 - 010213.dv” cannot be imported. It is more than 9-1/2 minutes long, which would be more than 2 GB once converted to DV. iMovie clips must be less than 2 GB in size. You can use QuickTime Pro to break the movie into smaller pieces, and then import the movie in segments.

So should I keep it as a DV stream or will I have to convert it to a quicktime movie?

You can use to demux the MPG the following app:
ffmpegx

I have already done this and have those files.

Open QT Pro 6, open the .m2v ( video) and .aiff (audio) files.
Select all of the video, copy to clipboard.
select the audio, add scaled the video to the audio.
Export as QT Movie using the following settings:

Instead of exporting it as a QT Movie can I export it as a dv stream so that the audio and video is together or do I have to use the 3ivx codec?

It was suggested in the previous post to convert the movie into a dv stream and then use either iMovie 4 or FCP 4 to import it and edit the file so I think it may be a good idea to keep it in a dv stream unless suggested otherwise.

(In reference to the demuxed mpg-1 file)
I have already done this and have those files.

iMovie4 will be ok.

Your problem is related to the size of the clips. the error you recieve:

Previously when attempting to import the movie to iMovie 4 I got an the following error.
The file could not be imported: The movie “G4 Speed/Volumes/FireLite 80 GB/p1 - 010213.dv” cannot be imported. It is more than 9-1/2 minutes long, which would be more than 2 GB once converted to DV. iMovie clips must be less than 2 GB in size. You can use QuickTime Pro to break the movie into smaller pieces, and then import the movie in segments.

Is pointing to that. To get around this, You need to bring the file in
either ( a) as a lower format, such as QT .mov, using the 3ivx codec,
which will offer some compression, but not enough to affect the overall
quality. DV is an UNCOMPRESSED format, and so your larger file size
is due to that. If you bring in the file in a editable compressed format,
then you will be able to edit it, without triggering the file limit warning
in iMovie. I am also guessing that your original individual VCDs are
less than 2 hours in actual running time. If so, then this will be the perfect
solution to your problem, and I have done this many times myself,
taking hour long VCDS, following my steps, and bringing in the
HQ QT .mov files into iMovie and editing them to make them seamless,
setting chapter markers, and then exporting the project over to iDVD.

Or (b) you can bring the file in as DV, but it will have to be in small chunks. Each chunk will have to be around 9 minutes long.
On editing a 2 hour+ movie, you will be sucking wind trying to import
9 minute brokedown clips of the DV file. If you had originally captured
from digital camera into iMovie4, it would automatically break the
stream for you as you import it. But since you are going from .mpg-1
( according to your original post) into iMovie4, you cannot convert
from mpg-1 to DV, as it will strip out the audio from the mpg-1 file,
and create an enormous large video only DV stream.

You would then have to take your demuxed files,
add scaled the video to audio in QT Pro, export that file
as a DV stream, thereby creating another huge file,
open that DV stream in QT PRo, and go in and break it down
into 9 minute chunks ( 01.dv, 02.dv, 03.dv, etc.)
and then import those chunks into iMovie and then edit them.
no Quality loss, but a HUGE pain to split and bring in the chunks.
( 2 hour movie / 9 min =13.3 clips you will have to bring in)

an Apple script exists to help in this process, but you will still have
a lot of files to manually import once the splitting is done.

http://www.oakstreetsoftware.com/qtscript.html

Personally, IMHO, Your best bet is to demux the mpg-1 file, follow the steps to create the hq QT .mov I suggested with the 3ivx codec, and then edit as necessary in iMovie.
Once done, you can then export out of iMovie 4 to iDVD and create
your compiled DVD, as stated in your original post. Your quality loss
will be VERY Minimal, and in trade, you will get a file iMovie will accept
(because it is of lower file size, and thus will not hit the automatic
size limit warning) and you will be able to edit ( both audio and video)
and get it over to iDVD.

Choice is yours.

[lansing]

Thanks terryj for your help. I think I'll go through your process since the other as you mention is only a minimal gain. However, I'm having some problems. This is what I have done so far following your guide line.

select the MPEG file in ffmpegx, demux back to elementary streams.
Open QT Pro 6, open the .m2v ( video) and .aiff (audio) files.
Select all of the video, copy to clipboard.
select the audio, add scaled the video to the audio.
Export as QT Movie using the following settings:

1. I've downloaded and installed the 3ivx codec.
2. using http://webpages.charter.net/ernsta/SVCD2DVD.htm I went through steps 1 through 4 which yielded a Part1.m1v (video) whose's extension I changed to .m2v and PART1_48KHZ.mp2 file (audio).
So far I have the following:
Part1.m1v, video file.
PART1_48KHZ.mp2, audio file, which is not the .aiff file format you specified. Do I have to convert the .mp2 to .aiff?
3. Opened both files into Quicktime 6.5.
4. Selected all the video by Edit > Select all (apple-a) which looked like it selected all the video.
5. I attempted to copy all the video to the clipboard but the "Copy" on the Edit pull down menu was greyed out. Any suggestions?
6. I though maybe that there was something that was quick and continued with your steps.
7. I added the scale by Edit > Add Scale which made a small black screen but didn't add the video.

Additional notes/questions:
The duriation of the VCD is roughly 3 hrs.
How do I Mux the two files to into something that imovie4 can read? I'll be sure to use the tools provided above to segment them the files to 9 minutes.

any help would be appreciate.

good. You are welcome btw!

PART1_48KHZ.mp2, audio file, which is not the .aiff file format you specified. Do I have to convert the .mp2 to .aiff?

It is not necessary, although some prefer to do it just to be safe.
The mp2 should open and play in QT pro 6.5 just fine.
And if it opens and you can play it, then you can manipulate it.

3. Opened both files into Quicktime 6.5.
4. Selected all the video by Edit > Select all (apple-a) which looked like it selected all the video.
5. I attempted to copy all the video to the clipboard but the "Copy" on the Edit pull down menu was greyed out. Any suggestions?

one...Are you sure you have QT Pro 6.5?
Easiest way to check...go to System Preferences--> Quicktime-->Registration, and make sure your panel looks like the following:


the Red Rectangles should have your name and your registered
Serial Number when you purchased it from Apple.
Once it is entered, the line below the serial number will read
as it is highlighted in blue; Quicktime Pro 6.

Without it the Pro keys, you will not be able to cut, copy, paste, add scaled any readable files. That what is "PRO" about QT Pro.

6. I though maybe that there was something that was quick and continued with your steps.
7. I added the scale by Edit > Add Scale which made a small black screen but didn't add the video.

make sure you have the QT Pro registered.
Once you have confirmed this, if this still will not let you copy
the m2v file, do this:

Add the following step:
With the m2v video file selected,
go File-->Export.
Export as Quicktime to Quicktime Movie.
Under Options, select the 3ivx codec.

then click options and set your options to match the Red arrows:


click ok.
There will of course be no audio with this new file,
but your video will be intact.
Now, open the outputted .mov file, select all, copy,
and then add this video (add scaled) to the audio
and play the file to determine it is ok. if so,
save as self contained .movie,
edit ( split into 9 minute chunks, trim unwanted footage)
save
then bring it into iMovie.

Additional notes/questions:
The duriation of the VCD is roughly 3 hrs.
How do I Mux the two files to into something that imovie4 can read? I'll be sure to use the tools provided above to segment them the files to 9 minutes.

any help would be appreciate.

Once you have compiled your mpgs to movies,
( and if you like, split the clips into nine minute segments)
then you can bring each into iMovie, and edit them down as necessary.
Then you will be able to create by exporting them from the timeline out
to iDVD or DVDSP2.

[lansing]

Steps so far:

1. Confirmed that I have Quicktime pro 6.5
2. Exported .mpg into .mov using 3ivx (.mov files has the sound and video).
3. Using the following script I converted them into 9 minute increments

http://www.oakstreetsoftware.com/qtscript.html

Problem:
Using the script it did convert it to 9 minutes but converted the movie to a dv stream which removed all the sound in the segments.

Question:
How do I export the file into a supported format for iMovie 4 meeting it's 9 minute or 2 GB limit while keeping the audio track?

click ok.
There will of course be no audio with this new file,
but your video will be intact.
Now, open the outputted .mov file, select all, copy,
and then add this video (add scaled) to the audio
and play the file to determine it is ok. if so,
save as self contained .movie,
edit ( split into 9 minute chunks, trim unwanted footage)
save
then bring it into iMovie.

The script does work in splitting the tracks into 9 minute and/or 2 GB chunks but it uses the last option settings to trim the video which like you mentioned there will not be any audio.

thanks for any insight

[terryj]

Steps so far:

1. Confirmed that I have Quicktime pro 6.5

great!

2. Exported .mpg into .mov using 3ivx (.mov files has the sound and video).

great! But you mean you:

Exported the .m2v file to movie, then selected all the video
from the new 3ivx movie file, and copied then add scaled to
your audio file right?
Just going File-->export-->mpg to Quicktime .mov will cause a
"Fake" .mov file to be created, one that doesn't contain a true
audio stream, and if you try to convert this over to DV stream,
the audio will strip out.

3. Using the following script I converted them into 9 minute increments

http://www.oakstreetsoftware.com/qtscript.html

Problem:
Using the script it did convert it to 9 minutes but converted the movie to a dv stream which removed all the sound in the segments.

Question:
How do I export the file into a supported format for iMovie 4 meeting it's 9 minute or 2 GB limit while keeping the audio track?

See above quote on #2.
Also,
Did you save the file as self-contained movie first from step 2, Close it,
re-open it and then run the script, or did you immediately run the script
after add scaling your video to your audio, before saving and closing out? If so, I could see the state of flux and why it didn't get the audio.

Steps should have been:
Open m2v video file in QT.
Export m2v file to 3ivx QT .mov file.
Select all the video in the QT MOV file, copy
select the audio file, go Edit--> Add Scaled.
Audio and Video will now be in the same file.
Save as SELF CONTAINED QT mov.

To verify your changes to files in QT, make sure:
1. Save as self contained .mov file
2. Close the file, then re-open it verify changes.
3. You can check and set your options for DV export by going
to File--Export--> Quicktime as DV Stream, selecting options,
making sure you set the Audio to locked, click ok, click ok
to encode, then when the progress window comes up, click
Cancel. The "Last settings" will now be what you saved.
Then run the script as directed.

Your almost there! Great job so far!

Another possible issue maybe the orginal VCD was in PAL and I need it in NTSC.

It was converted the .mpg to .mov using the 3ivx.
But reviewing your notes I did the following.
movie,
1. open the demux file (.m2v) in quicktime pro.
2. Exported the file by File > Export using the 3ivx codec into a .mov
-- codec settings were
quality: best
frame rate: as specified (image)
limit data rate to: 90
3. Opened the outputed file .mov.
4. Opened the .mp2 audio file.
5. Copied all the video from the .mov
6. Edit > Add Scale to the .mp2 file.
7. Checked for sound and video. (worked)
8. save as self contained QT mov
9. opened the new .mov file opened the file to confirmed audio and video (worked).
** interesting thing is that when I opened this file I can not trim copy or cut the video. All selections are greyed out.
10. Checked my settings by going File > Export > Movie to DV Stream selected options locked audio.
12. Exported to save the setting otherwise it would not save as Movie to DV stream.
13. Canceled the export.
14. Used the script to export it into 9 minute DV stream segments.
15. Result - No audio with the video.

what am I missing? TIA.

Possible, but not likely.

** interesting thing is that when I opened this file I can not trim copy or cut the video. All selections are greyed out.

ok, this is scaring me, because you should still have selections.
Add this step here:
9a. with the add scaled file open, go File--Export-->quicktime to Quicktime Movie
use the 3ivx settings again. Once done, close out, re-open and then verify:
---that your audio and video are intact.
--that your menus are not greyed out.
if so proceed to step 10.
if not , post back.
It is still not making a "true" QT Movie file, and we will now through step 9a, force it to.

10. Checked my settings by going File > Export > Movie to DV Stream selected options locked audio.
12. Exported to save the setting otherwise it would not save as Movie to DV stream.
13. Canceled the export.
14. Used the script to export it into 9 minute DV stream segments.

Looks like it was an issue with the audio format. However, it looks like the DVD quality is not much better than the VCD quality originally for obvious reasons.

Going through all the different twists and turns I found something interesting. I found that you can create 1 DVD using the .mpg(s) that were extracted from the original VCD. The only problem is that the DVD becomes a PAL version rather than the NTSC version that I require through Toast 6 and it doesn't let you convert it to the NTSC version. The DVD (PAL) works fine with the apple DVD player however the stand alone dvd player doesn't want to recognize it do to the region issue. Using QTPro 6.5 I found that it was a MPEG1 file but QT PRo doesn't export in that format.


Questions:
Is there any way to convert the .mpg files that were extracted using galactica's tutorial (http://webpages.charter.net/ernsta/SVCD2DVD.htm) into NTSC versions so that I can duplicate the creation of the DVD to a version supported by my DVD player.

Is there any way to edit/delete parts of the mpg(s) before I let Toast 6 or something else anyone can recommend burn it.


thanks for all your help.

Well...if you were a legacy Toast user who upgraded from version
5.x to 6.x, you would have the Toast Video CD plugin for QTPro6,
which would allow you to export MPEG-1 files natively from QTP6.

thanks for all your help.

Again, if the files are converted to QT movie using the settings I described, it should produce a 29fps QT movie, that is fully editable,
and at 29fps, you could edit the movie, drag and drop it into Toast6,
and create a NTSC output. ( 29fps is NTSC, 24fps is PAL).

When the codec creates the movie file, it will rencode it at 29fps to the new movie file and create a new keyframe at every 90 frames.
This will be fine for NTSC format.

try this ( be sure to fix the audio!) and post back.
