Movie Goes Out Of Sync

[brockodore]

While I'm Trying to encode an avi the audio goes out of sync with the video after about 15min and gets worse as the movie goes on. My presets are From: avi To: DVD ffmpeg Video Codec: MPEG2 [.MPG] (ffmpeg) Audio Codec: .MP2 Options: High Quality, Decode with Quicktime.

This only started after I installed the latest version and the new binaries so I went back to 0.0.9w to fix this but it still doing it. Toast 7 will encode properly but the quality is crap compared to ffmpegx.

Is there a fix to this or am I doing something wrong. I have searched the forums and only found fixes for aut of sync audio the whole way through a movie and nothing about the audio slowly going out of sync as the encoding process progresses.

Thnks in advance

I don't mean to insult you, but if the quality of video that you compressed with Toast is not satisfactory, that is most likely because your configurations on Quick Time codecs or DivX or whatever aren't right.

I'm Not compressing the avi with Toast I am encoding it to DVD. I have just thrown away the Ffusion codec from the Quicktime folder because I have read that it stuffs up Divx and it also coincides with the time my syncing issues started. I will give it another go and let you know how it went

Ok, If I encode using ffmpeg it works fine but the picture looks stretched like the start of a 1960's movie. If I use ffmpeg and the option encode with Quicktime the audio goes out of sync like before. If I encode with mpeg2enc everything is fine except when I try to burn the video.ts folder with Toast 7 it gives me the error that it is an encrypted DVD and won't burn and it takes ages to convert unlike the ffmpeg encode. Thats no biggy I just burn the folder with Dragon Burn.

I would like to use the ffmpeg conversion for the speed but I don't like the stretched picture. How can I get the picture to stay at Letterbox without using the Encode with Quicktime option.

Please try to help. This is annoying me. Thanks

I had problems with ffmpegx screwing up the aspect ratio when converting from avi when I use "DVD ffmpeg". But when I use "DVD mpeg2enc", it keeps the original aspect ratio of the avi.

[brockodore]

Same here. But using the DVD ffmpeg is a lot quicker than mpeg2enc so I was wondering if there is a way to keep the aspect ratio using DVD ffmpeg.

Just a couple of thoughts on the sync issue (or lack of. . .)

A while back I posted a message going into detail about my problems with this problem.

Here are somethings I found out;

Nero now claims that it is fully compatable with my video device (a plextor 402U). They even sent me a copy of their info sheet. I'm sorry Nero, but just printing it on a piece of paper doesn't make it so. The guys at plextor said I shouldn't use Nero for capture.

One of the major problems that I had with Nero was that the aspect ratio never matched from capture to capture. Every time I used it I never knew if the apect ration would be correct.

I went back to Intervideo WinDVD which is what Plextor recomments. It's clunky and you don't have a lot of "creative" options, but it does what it does well. . .very well. Also, some of the other programs I have used for editing have a real hard time moving through a video file. . .you have to move in the timeline, and then wait for the computer to catch up. Moving in Win DVD is in real time. . .at every slip second you go to exactly the precise position of the time line. . .no delay. (And there is the fact that trimming files in Nero has the most cumberson, crazy was a cutting a file. Blech!!)

I'm using DviX and Mpeg 4 for the captue. . .the 402U uses hardwire DivX translation and the sync is rock solid at that point. I let WinDVD do the rendering. . .it's slow, but accurate.

(One note, because of the double whammy of these compressors, do not believe the bar graphs showing you can't fit this all on one disk. As long as the graph shows less that three hours you should be fine at this point. Ignore the error message. Be brave!)

Then, and I only use it because it will include a "Verify option" that should be checked, I use Nero Burning ROM for the final step.

If, and this has only happened to me twice, the burner chokes on the size of the file you can always use Nero recode to get it down to size.

At that point, I can either use the resultant avi file, or the regular dvd files in anything else you want to try. I have to admit that I have used only four or five editing programs, but the system seems to work now.

And remember, this is using the Plextor 402U and WinDVD with DivX and mpeg 4.

Your milage may vary. . .

Figured it out. Pretty stupid really. Just dropped the avi file in. Picked DVDffmpeg, AC3 Dolby Digital, High Quality. Then under the Filters Tab/Letterbox I set the Top Black Padding Size to 160 and the Bottom Black Padding Size to 160. Pressed encode and viola. Perfect encode.
