AVI to DVD MPEG (CCE or TMPGenc encoders)

[DJRumpy]

Most menu's themselves take up a meg or two, and most bitrate calculators take that into effect. That would be part of the overhead Manono was referring to. The files themselves take up a bit extra, as do the menu's.

I always extend the time a minute or so for any unexpected overhead just out of habit.

Well usually for me they are bigger because I like doing the menus where the chapters show like 15 seconds of video. How does the bitrate calculator take the audio into account does it assume you are using AC3, MP3, WAV, etc. as your audio.

I just hope I'm doing it right because I was using a combination of this DVD PAL to DVD NTSC guide http://www.eggshellskull.com/pal2ntsc/ and this guide that you posted. I got my script border values using what this guy did https://forum.videohelp.com/topic185077.html but I also add the Crop values into the AddBorders calculations.

Here my avi specs given to me through AVIcodec.

File : 698 MB (698 MB), duration: 1:31:37, type: AVI, 1 audio stream(s), quality: 54 %, Nandub v1.0rc2, ,

Here's my

For some reason when I open the avi in virtualdub mod it shows the video being 1:31:37 and the audio being 1:31:54 and even saves the audio at 1:31:54. However when I open the avi with regular virtualdub it shows the same but when I save the audio it comes out to 1:31:37 just like the video. Is the audio of this avi corrupt.

So what I did was just saved the audio into a uncompressed wav file using regular virtualdub and using the option to convert to 48,000hz from 44,100hz and then using AC3Machine to convert that into a AC3 audio file.

Am I doing this right? Oh and if it helps in both regular virtualdub and virtualdub mod i was getting that one error that you had explained in the guide but i was confused about how you explained how to do the audio part and how to do it. The way it was written through me off. The warning about VBR audio being detected. Could you explain that part and what to do with that.

[DJRumpy]

If your doing animated menu's, then you would need to encode the mini-clips first and subtract their size from your final output. Almost all decent bitrate calculators will show you the final output size. Just encode your menu clips, subtract that from the total allowed, and tweak your bitrate until the output size is below that.

For the audio, most bitrate calculators will also ask you what format your audio is, and what bitrate because each container for the audio has different overhead.

I'm curious. Your source is an AVI, probably with no letterboxing. Why are you cropping it further? Your video is also already 25 frames per second. You don't need to use the AssumeFPS.

The audio isn't necesarily corrupt. I've often had mismatching times, yet they sync up normally when the project is complete.

The error in VirtualDub about VBR audio can be ignored in your case since you are feeding your audio in via the AVISynth script and your using the EnsureVBRMP3Sync function.

[richard_m_morales]

I thought I was supposed to use that AssumeFPS anyway. Oh well I just copy and pasted the stuff. Oh and I'm cropping because of what the DVD PAL to DVD NTSC one was. So would it be better if I took that part of then. So I take that off and then leave the addborders well adjust the addborders rather.

Hi all,
I continue to use this guide and have learnt alot about converting Avi files over to DVD. I have another question. I have encoded an avi file, all the calc and DVD bitrates are fine.

I am using DVD lab pro to author the encoded files. On one avi file I encoded everything was recorded perfectly. for example the mpa file was 1.39.55 and the mpv file was 1.39.55.

However when I compiled it to DVD, the audio was out of synch. Is there any way to fix this after compilation ie what programs would you use and how do you do it and can anyone enlighten me as to what went wrong in the encoding process?

Thanks for all your help, I have found this topic to be extremly informative

OK I've followed this guide and have had success with it. I have a question thought how would I go about it if I'm using a PAL DVD to NTSC DVD and want to keep the menus from the original PAL DVD. I got the conversion rate/the main movie/vobs done but how would I got about keeping the original movie menu set up from the PAL DVD.

[manono]

Hi-

I have a question thought how would I go about it if I'm using a PAL DVD to NTSC DVD and want to keep the menus from the original PAL DVD.

The short answer is, you don't. Unless you're very knowledgeable, your best bet is to convert static or motion menu backgrounds to NTSC and then use them in an outside authoring app to have it make the sub-pics and buttons for you. A free app like DVDAuthorGUI can do the job, if you have all the M2Vs, or lots of retail programs can, as well.

If you have NuMenu4U (free) and Scenarist (very expensive), and are prepared for a lot of headaches, you might try this guide:

http://www.ntsc2pal.hostrocket.com/FramesetMenuRipping.htm

[richard_m_morales]

Awww that sucks there's now way I can just edit the files (ifo, vob, etc.) to convert the whole thing to NTSC from PAL.

[manono]

Yes, the discredited patch method. It's not a valid solution, in my opinion.

[richard_m_morales]

So that's the only way dang. I really wanted to keep the original menu's.

[manono]

It's possible. I've done it a couple of times. It's just hard. You have to reencode the background menus, static or motion. You have to resize all the menu sub-pics to 720x480. You have to save out and add back in (PGCEdit) the menus and color schemes, adjusting the button highlight locations (is that the correct term?) for NTSC. You have to mux together the M2Vs or BMPs, the resized sub-pics, (made back into SUP or SST format for Muxman) and the audio. You have to replace all the individual menus in the new NTSC DVD. It can be done, but by making the NTSC M2Vs, you can use an outside authoring program to create new sub-pics and buttons for you. When using an outside program to do the hardest parts, the result should wind up pretty similar to the original.

[richard_m_morales]

Can you point me to a guide for doing this? I could care less if it sounds hard I'd still like to give it a try if I could find a guide which I haven't been able to do.

Maybe you should study manono's guide for menu extracting to get an idea of how menus work before diving into the conversion to NTSC process:

https://forum.videohelp.com/topic313743.html


I think I pretty much follow manono's way of converting the menus to NTSC manually as I remember we had a discussion about this a long time ago. I don't think his guide tells you how to rip out the subpics. But you can do it with subrip. Then for resizing the subpics to NTSC I like to use XNView. You can only use bicubic to resize though. But like manono said it's not an easy thing to learn.

[richard_m_morales]

OK well thanks for the replies guys I'm gonna give this a try but not any time soon since school started I don't think I'm gonna have the time.

Hello DJRumpy

Thanks very much for this guide.

At the begining of the guide you have written that:

I will also cover converting AVI files with 5.1 AC3 audio, and how to retain that 5.1 audio for your DVD MPEG in it's native AC3 5.1 format.

Sorry, but I could not locate anything specific for AVI files with 5.1 AC3 audio. Could you plese add a section in your guide covering this particular case? I would like to retain the 5.1 AC3 audio and use it in final DVD. And I do not encode the audio strem with encoders, I shall just feed this stream directly in the Authoring tool.

If I simply Demux using VirtualDub, will the Audio be retained as a 5.1 stream?

[manono]

If you Direct Stream Copy the audio (just Demux it), it'll be whatever was in the AVI. Why do you need a guide for that?

[src2206]

No I do not need a guide for that. That is why I've written the last line in my previous post. If that is the way (the same you have pointed out) then fine...no worries. But if not, (which is not the case I believe) then I would have needed some guidance, if applicable.
Hope I have made myself clear.

Manono it is my habit to taste the water before I jump and I am always open to leaning, and that is why I am still indebted to you (and others like guns1inger, Matts, Scott) because you have enriched my knowledge about this subject, though some of your comments really hurts. And btw, learning is a constant process and sharing do increase knowledge, IMHO.

[DJRumpy]

The information is already there. You would extract the AC3 audio from both avi's, and join them together using the method in the guide for joining audio, and then run AC3 Fix (also mentioned in the guide) on the joined AC3 dio. It doesn't refer to 5.1 audio specifically because not all AC3 audio is 5.1.

If your AVI is only a single (non-split) AVI, then just demux the audio using VirtualDubMod.

Once your video is encoded, you would just mux the joined AC3 audio into your MPEG.

The guide does tell you how to handle that (just look at the AC3 Audio section) and shout if you get lost.

[src2206]

Thank you very much DJRumpy, its clear now.

[kio]

Hi DJRumpy !


Can you given some example how to access our AVI file with AVISynth & open AVISynth script.


Thank's lot !

[DJRumpy]

kio, please read the guide. It walks you through that process.

Hi! I got a problem,when idrag & drop "movie.avs" file onto VirtualDubMod, VirtualDubModget freeze & shutdown.
This is my Avisynth script.




AVISource("E:\Marc Dorcel - Le Maitre Chanteur\movie.avs",false)
ResampleAudio(48000)
LanczosResize(720,480)
AssumeFPS(25, True)
ConvertToYUY2()

Could you see WHAT i did it WRONG. Thank,s a lot.

[manono]

I don't know if this is the reason for the VDubMod shutdown, but you disabled the audio with the "false" in the AVISource line, and then have another line resampling the audio (which no longer exists). Try removing the ResampleAudio line and the "True" in the AssumeFPS line. Either that or remove the "false" in the AVISource line.

[Woo]

hi guys i am new of this thing.there is some body can explain clearly how to

Repairing AC3 Audio. i am stuck with this explain here it confuse me.


(Ensure that AC3FIX.EXE is either in your PATH (in your Windows directory for instance), or in the project directory. I'd suggest you just copy the AC3FIX.EXE to your WINDOWS or WINDOWS\SYSTEM32 directory. The format for the command is simple

AC3FIX.EXE "file to fix.AC3" "fixed filename.AC3"

The quotes are necessary if any of the path to the AC3 file has a space in it (C:\Program Files\ for instance). The 'fixed' filename is simply the fixed AC3 filename that will be generated. Both paths in quotes should contain the FULL path to the AC3 file (both input and output). If you do not include the full path, AC3Fix.exe may fail, or it may create the fixed file wherever your AC3FIX.EXE file is located. Since my audio source is AC3, and my example AVI was split into two pieces, I would specify the old audio file and the new audio output file like so:

AC3Fix.exe "c:\project folder\audio.ac3" "c:\project folder\fixed.ac3"

You would, of course, replace the above paths in quotes with your own project folder path and filenames. When the program runs, it SHOULD report a bad frame or two for AC3 from a split AVI file. This is normal and expected.
(example of an AC3 with an error)

[Woo]

Avisynth open failure: avisource autodetect: couldn't open file (D:\conversion\movie.avs, line1) when i drag and drop movie.avs onto vitualdubmod.

this is what my avs file look like:



AVISource("G:\joined.avi",false)
EnsureVBRMP3Sync()
ResampleAudio(48000)
LanczosResize(720,480)
AssumeFPS(23.976, True)
ConvertToYUY2()

[poisondeathray]

Woo - you might want to try the acfix gui instead

www.videohelp.com/tools/AC3fix_GUI

Your script uses avisource, but specifies audio as false. You then go on to specify audio commands e.g. resampleaudio() - that's probably causing the error. Try taking out the "false"

[Woo]

Thanks to reply!
1ST thing i want know do i have to repair my audio or not if my audio is
MPEG-1 Layer 3 which it is a mp3 format

[Greensmurfet]

Hi, not sure if anyone is still monitoring this thread but here is my situation.

Followed the guide. Encoded the movie using CCE. The original movie is about 1:50hrs long. I am changing from Pal 25 to film 23.976. Its AC3 audio and after converting that with ac3machine from pal to film, it is much slower than the movie. I have gone through the end of the film and the beginning and don't see anything wrong with it. The only other thing is I assumed it was progressive when I encoded and it is playing fine. I tried checking it out on Vdub frame by frame and it looked like it was progressive so I marked that flag on CCE before encoding... Should I some how speed up the audio to match what I have now? The audio length is 1:45:57. The movie after encoding is 1:50:22. The movie is running faster even though it is longer. I will see if maybe I just need a few seconds lead....

Thanks for any help.

[DJRumpy]

From your post above, it appears the duration of the movie did not change? It should have also been longer due to the shift from 25 to 23.976 frames per second. If the duration both before and after the encode is the same, then your problem lies there (it wasn't converted from PAL to FILM).

How long was the duration of the audio and video both before and after the encode?

[Greensmurfet]

I miss typed slightly. Ok. The movie before encoding was 1:45:57 and after encoding 1:50:22. The audio was AC3 and when extracted it was 1:45:57 (of course). I didn't do anything to the audio because I didn't see it mentioned in the guide... maybe I'm wrong.

So the mpeg movie was about 5 mins longer after encoding from 25 to 24. Does that sounds about right or should it have been even longer?

What do I use for the audio to convert it from 25 to 24?
