Frame rate and Audio sync

[peterhun]

Hi all, I have an avi that I'm trying to get to DVD. Using G-spot it is an DIVX3, FPS 30.111, audio MP3 44100Hz CBR. The audio is pretty well in sync in the avi but when re-encoded it loses sync enormously. I have tried ConvertxtoDVD (to vobs), TMPGEnc (to mpg), and tried to resync the mpg using VideoReDo but it ends up worse towards the end of the movie. Also using TMPGEnc to .mpv/mpa and then using DVDLab the audio is also out of sync.

I think it is because of the strange frame rate. I'm not concerned whether the output is PAL or NTSC. What is the best way to get my project to DVD format please.

Encode as 29.97 fps NTSC, as this is closest and will do the least damage (unless you want to see if you can IVTC it). Once it is encoded, use g-spot 2.60 or virtualdubmpeg2 to find out the exact running time of the video, then use goldwave or sound forge (or perhaps even audacity) to change the length of the audio to match.

Thanks guns1inger....so what program would you recommend I use to encode (that you use) and what format do I end up with, is it mpg or elementary streams.

Because you need to alter the audio, I would just encode the video stream separately. For free and good quality, I would use FitCD to create an avisynth script that will load the video and alter the framerate. I would load this script into the free mpeg2 encoder HCEnc to get a video stream (I use ProCoder, but it's not free or cheap. HCEnc produces very good quality). I would use virtualdubmod to save the audio as uncompressed PCM -> https://forum.videohelp.com/viewtopic.php?t=309224 will tell you how. From there you can use an audio editor, or perhaps besweet to change the length and encode it to AC3 for authoring.
