Converting AVI files to mpg using Tmpgenc Plus 2.5

[joolzhaines]

Hi,

I am new to converting and I am having a problem converting avi's. I am successfully converting some of my avi’s but some when finished converting have no sound, Is it true that some avi have compressed audio and some don’t and the one’s that I am converting ok are the one’s that are not compressed. If this is the case how can I get the avi in a format that Tmpgenc will convert audio and all.

Thanks for your help

When that problem comes up, remember to convert the audio to a wave file, and load the original video and the new wave file into TMPGEnc Plus.

To extract the wave, use Virtual Dub mod, and select File-->Save Wav...

If you hear the sound when playing back the video..obviously you have the codec needed.........try going to Environmental settings in TmpgEnc and making sure Directshow is listed at the top and VFW is second...otherwise do what is suggested above.

I also have a problem with converting. I have an avi file which I successfully converted into mpeg but! I want to burn it on DVD and I have problem with the fps which is 23.976. Since this stuff is NTSC, I should make it 29.97. When I do, I get a serious lip synching as an end result.

How can I solve this problem?

Try using 3:2 pulldown playback & set your frame rate to 23.976 fps 29.976fps internal. That should produce a progressive video file to match your original audio from your 23.976 fps source.

"set your frame rate to 23.976 fps 29.976fps internal"

I'm sorry, I don't really understand this. When I try 29.976 fps internally, I get a very slow video because it is 14.985 fps (internally 29.97 fps).

Should I do the video and audio separately anyway? By far, I did them separately.

In settings on the VIDEO tab in TMPGEnc, set the encode mode to '3:2 Pulldown when playback'. Then set the frame rate setting to '23.976 fps (internally 29.97 fps)'. If your source is 23.976 fps, then your outputted file should playback at 29.97fps using this setting. I would just do the video stream and then mux it with the audio from your original 23.976fps source. That should do the trick.

"Then set the frame rate setting to '23.976 fps (internally 29.97 fps)'."

Yes, I see, but this is what TMPGenc doesn't allow me. The only option with an internally 29.97 fps is the 14.985 fps. I understand the trick but for some reason I can't do it.

The problem still exists.

Let's start from scratch. I still have the avi file w/23.97 fps.
How can I make a DVD out of this file without lip synching problems? I need 25 or 29.97 fps.

Okay, if you are going to try and do 3:2 pulldownin TmpGenc then under the VIDEO tab goto the ENCODE MODE and select 3:2 pulldown and go up to FRAME RATE and choose 23.976 (29.97 internally). If you are unable to do this or if there is a problem doing this than let us know.

Personally I steer clear of 3:2 Pulldown because of the jerkiness it puts on the video. Most DVD players now will take a 23.976fps file and automatically play it back at 29.97 if necessary, at least the new ones do but you would have to test this on yours.

As for the audio/video sync problem the causes are several possibilities. If the AVI file has an error on it(as most do) then during encoding the video will lose sync and the audio will stay on resulting in GUESS. If this is the case you would have to fix the error by one or more of the following. Load up the AVI in VirtualdubMOD and scan for errors. If they are present than click 'Show Bad Frames' and write them down. Then using the MARK-IN and MARK-OUT buttons, goto the first bad frame and mark-in and then goto the next one and mark-out then choose 'delete frames'. Do this with all the rest of the bad frames. This will cut out the bad frames including the audio. Then you can resave a 'direct stream' AVI copy BUT also save a WAV copy so you have a copy of the repaired audio as well. Then try encoding as usual. If you end up with more sync problems then there is still a bad frame present. Using this method may cut out small parts of the movie so if this is a problem then videofixer can fix it without removing parts.

Another way to find bad frames(better)because VDUB doesn't always see errors, get videofixer and load the avi up and click CHECK. If there are errors it will list them. Just write down the bad frames and do the same as before in VDUB.

If you still have a problem you can always let videofixer FIX the problem. 99% of the time it works perfectly and all you have to do is click FIX.

Good Luck.

Never come across one that will do this for DVD-Video (or any mpeg-2 for that matter). Many (most?) VCD compatible player will do it for mpeg-1. It is a requirement of the VCD spec as mpeg-1 does not support 3:2 pulldown flag. But mpeg-2 includes 3:2 pulldown flags so the player doesn't have to do it automatically.


@kidkash, as others said, use the 3:2 pulldown settings in Tmpgenc. If Tmpgenc won't let you change a setting, click on the text for that setting (e.g 'Frame Rate') and click 'unlock'. Then you can change it.
