MPeg1 or Mpeg2

[razzcal]

HI....How can you tell if a file is an Mpeg1 or Mpeg2

I have a collection of AVI's which I want to place on a DVD-r first to have more than one on a dvd opposed to CD-r and second to play in a stand alone player.... I have been reading alot of the guides and posts and I am pretty confused....Any help, info would be appreciated..

Thanks

How can you tell if a file is an Mpeg1 or Mpeg2

By viewing the files properties with GSpot or most any compatible video program.

I have a collection of AVI's which I want to place on a DVD-r

You should give us more info about your AVIs. ok

Well, first off it will have the file extension .mpg, and to tell the difference between mpeg1 or 2 then you can use Avicodec and it will give you the resolution and file type.

To play your avi's on a DVD player you need to "convert" them to DVD compliant mpeg and "author" and burn it as a DVD, or you need to convert them to Divx type avi's (if they're not already) and put them on a DVD and then you need a DVD player that will play Divx. Your choice.

Ok I downlaoded Gspot and AVICodec.......now how do I check to see if the AVI is good....

[razzcal]

In AVI Codec this is what I get:

File: 687 MB (687 MB), duration: 0:53:59, type: AVI, 1 audio stream(s), quality: 80 %

Video : 598 MB, 1549 Kbps, 29.970 fps, 512*384 (4:3), DIV3 = DivX v3 MPEG-4 (Low-Motion), Not checked

Audio : 88 MB, 231 Kbps, 48000 Hz, 2 channels, 0x55 = MP3, Supported

File: 687 MB (687 MB), duration: 0:53:59, type: AVI, 1 audio stream(s), quality: 80 %

Video : 598 MB, 1549 Kbps, 29.970 fps, 512*384 (4:3), DIV3 = DivX v3 MPEG-4 (Low-Motion), Not checked

Audio : 88 MB, 231 Kbps, 48000 Hz, 2 channels, 0x55 = MP3, Supported

So you have a Divx type avi file that is 54 minutes long, 512x384 resolution and 29.97 fps frames rate. The audio is MP3.

You need to "Convert" it to DVD compatible mpeg, I suggest TMPGEnc for that. Then you need to "Author" your mpeg(s) (you can put more than one into your authoring program) and then burn to disk. Guides for each step are in the green section on the left hand margin. <-<-<- over there

I guess they weren't MPEG 1 or 2... hehe

[razzcal]

thanks for the help Zippy P and Bottlenecked I will try that.....

I know they werent MPEG's

I was also asking if you have an MPEG file, how can you tell if it's a 1 or a 2...

I will try the vdub to see if there are any probs

Razz

[razzcal]

Ok I checked the avi's with Virtual Dub and no errors or freezes....Now i should run it through Tmpeg to convert it ( will it be bigger in size when its done or smaller...

Thanks

Ok. Tip:

Go ahead a run them through TMPGenc but I don't suggest you start with the entire 55min movie to start with. Follow the program to the point where you can choose to 'crop' the movie before the reencode and only select a short portion of the video, say 1 minute section, and reencode that. Go view the new clip in a player, view the properties of this clip with whatever application you prefer, maybe takes some written notes, maybe get someone else's openion about visual quality levels of various settings, then try for the long haul reencode.

During reencode make sure your screensaver is turned off, you're offline, close all unnecessary applications and autorun program,etc and leave the computer along to do it's thing. So many people wind up with video/audio problems that can be caused them playing with the system while it's working very hard.

Good luck.

Oh Yea. Make sure your setting are compliant for your type of project. Don't reencode for hours to find out something is not right.....

[razzcal]

Ok thanks for the tip....I will give it a try......

[razzcal]

Ok I cropped about 1 min and reecoded it...upon playback the audio was pretty lousy..the video was good

[bottle-necked]

That may be because your reencoding the audio to a lesser value (kbps) than you should be. I see your originals was 231Kbps, 48k. If you aren't hurting for space I'd leave these levels as is.

If the original file sounds fine then the encode is the problem. TMPGenc is changing the audio settings. Sometimes these are greyed out and nonadjustable. You can De-Multiplex if you want, re-encode the video, then Multiplex the audio back in.(?) It's ac3 I see, you might want mp2. You can convert the audio while it's out, that's not a big deal either.

What does it sound like?

[ZippyP.]

Not normally. I surf and do all kinds of things while encoding, never had a problem yet. It will slow things down though.

[bottle-necked]

problems that can be caused

Considering the problems I've had in the past with 'some' programs.
Considering how sloppy 'some' programs are written.
Considering how little I know about anyones computer that may read my post.
I haft to suggest that he 'lets his computer encode' and 'shut down all unnecessary applications'.
Judging by my experiences, thats the safest way.

Ok I checked the sound on the original and it's not that good so it rencoded the same way...

I ran the entire file through TMPEG and this what I got:

The AVI file was 703,626kb

The new MPEG file is 2,869,177kb

Hoe come it made it so large

MPEG-2 uses less compression than DivX/Xvid which is MPEG-4 so it is normal for the file to get MUCH bigger.

As for the audio what are you settings in TMPGEnc?

Also ... make sure you have the audio in TMPGEnc set to HIGH QUALITY (LOW SPEED)

This setting is under OPTIONS (at the top) then ENVIRONMENTAL SETTING ... then go to the AUDIO ENGINE TAB.

Change it once to HIGH QUALITY (LOW SPEED) and it should always stay that way. For some reason though the TMPGEnc default is LOW QUALITY (HIGH SPEED) so you have to change it once yourself.

P.S.
For audio either use LPCM or use MP2 with a bitrate of 224kbps and use STEREO not any of the other options (such as JOINT STEREO).

I dont seem to have a Audio Engine Tab ...Im using TMPGEnc Plus ver 2.5

Where do I set the audio and is there a way to make the file smaller

Thanks

PLEASE don't be an idiot and look again. I even told you exactly how to find it.

I mean really now ... does mommy still wipe your pee-pee for you?

As for making the file size smaller the lower the bitrate the smaller the file but if you make the bitrate too low then the IMAGE quality will not look good.

Maybe this will help ...

Audio Engine Tab, huh? I don't understand. If you have a Divx AVI movie and load it in TMPGenc Plus for conversion to MPEG2, the audio is in the AVI!! I still don't understand what you mean. ok.

The movie was 55 minutes I believe, and the resulting filesize was 2,870MB. That's 2,870/(55x60)=.87x8=6.96Mbps average bitrate. 4350/.87=5000/60=84 minutes on a DVD. If you want more time on that DVD then you'll haft to lower the average bitrate. You can do that in TMPGenc on Wizard page 3/5 "Other Settings". How much time do you need? You already have almost 1-1/2 hours.

That's one of the reasons for doing short clip tests. You get a chance to look at the video quality verses the bitrate, do your math calculations, then decide on a template for the finished project. And its faster that way.

Good luck.

Did a large comet trail pass through the Earth while I was sleeping in a bank vault and protected by the deadly DUMB rays that the comet sent towards Earth making everyone a DUMB STUPID ZOMBIE?

I mean really HOW is this so hard?

Open TMPGEnc and kill the WIZARD if it starts.

At the top it says FILE OPTION HELP

Click on OPTION

Under OPTION click on ENVIRONMENTAL SETTING...

The ENVIRONMENTAL SETTING window pops up. There are several TABS for this screen. One of the TABS is labeled AUDIO ENGINE

Clik on the AUDIO ENGINE TAB

Change it so it looks like this (oh a picture what fun!)



Oh joy!

Ok i went to enviromental settings ...the tabs are as follows..

General CPU Sound External tool VFAPI Plug-in


Sorry no Audio Engine...Maybe I have a differnet version

[lordsmurf]

Everybody get on TMPGEnc 2.5.20.x so you can speak the same language. It would help, as every TMPGEnc version is different.

You MUST be kidding me.

You didn't think to click on the SOUND TAB?

I mean really now.

This thread is SO sad.

[macleod]

and people wonder why I recommend dvd2svcd all the time. For people that dont want to take the time to look for things.

download dvd2svcd

go to the encoder tab and open it check tmpgenc (if it isnt already ticked) go to conversion tab (or one of the others since I cant remember the specific one). Look for avi and check it. Check the appropriate mpeg1 or mpeg 2 that you want.

open the avi

click one of the tabs that has start on it. wait several hours and your mpeg will be ready for burning.

[razzcal]

macleod,

I tried the dvd2svcd it worked great ..the MPEG file it created was almost the same size as the original 703kb....and no loss of quality...but...

I am curious why it also created a Bin file of the movie and a smaller MPEG file that was a consensed version of the Movie....

Thanks

Razz

[macleod]

there is an option to check or uncheck for making or not making bin files. If you use dvd2svcd right, you will add a title page and a change disk picture (they have the defaults already set up) then, with nero or other burning program burn the image and you are done.

In nero, click file and then burn image.

As far as the 2nd condensed version of the movie, I have no idea what you are talking about? depending on how many discs you selected you will get one or more images to burn? Please give me some more detail.

[razzcal]

Ok now that I have converted the avi file to mpeg I have to now make some chapters and burn it a few of the files to one dvd...

[macleod]

you do know that you can go to the number of cd's tab and change the time to be the length of the video, change the number of cd's to 1 and change the size to say 4200 and then you would get one big file of the video so the movie wont be broke up....
