Converting fps - huge audio sync problem

[kidkash]

Hi everyone,

I have some avi files which I would like to turn into DVD-compatible mpeg. The fps of the avi is 23.976. I need to make a 25 or a 29.97 fps mpeg obviously because only these two frame rates are accepted by TMPG DVD author. When I try it w/ TMPGenc, I get this audio sync problem. I even tried to use Virtual dub, I created a wav file and tried to convert the video of avi and this wav together; still, I get huge lip synching. Could someone please describe very clearly - I am silly sometimes - how to do this converting correctly?

Thank you in advance.

You should be able to input a 23.976 file directly into TMPGENC and produce and NTSC DVD (29.97 fps) - it'll take care of everyhting,

otherwise follow this (it works for 23.976 -> 25.000 and vice versa but NOT 29.97)

1. Open AVI in Virtual Dub
2. In File menu, select 'File Information' note down audio info (like compression method, etc.)
3. In audio menu, select 'No Audio'
4. In Video menu, select 'Direct Stream Copy'
5. In Video menu, select 'Frame Rate', then select 'Change Frame Rate To' and enter 25
6. In File menu, select 'Save AVI' (save as new name!)
7. In Audio menu, select 'Direct Stream Copy'
8. In File menu, select 'Save WAV' (on the pop up select 'All Files' as opposed to *.wav, save audio with correct extension - usually .mp3, see 2)
9. Use BeSweet to convert MP3 to another format (MP3, MP2, AC3) and select the change frame rate from 23.976 -> 25.000 functionality
10. Convert new video & audio files to DVD using DVD 16:9 template (if widescreen) in TMPGEnc+ (video arrange method = Full Screen Keep Aspect Ratio), use 2 pass VBR for best quality
11. Do not convert the audio in TMPGEnc+ if you made an AC3 in 9
11a. Go to bed for 12 hours
12. Use TMPGEnc DVD Author to author (also allows 'muxing' with AC3, i.e. select DVD video file from 10 and AC3 audio file from 9)
13. Have a coffee / beer / smoke - you deserve it
14. Test output in Power DVD or similar
15. Burn disk in TMPGEnc+ DVD Author
16. Put in standalone and enjoy

I use this method and it works everytime as long as the AVI is ok to start with,

Look on this site there are many guides for 23.976 -> 25.000 fps conversion, BeSweet (+GUI), etc. thats how I learn't.

Thankfully there are some bloody clever people ot there (thanks guys)!

To do all this you will need 10.5 -> 11.5Gb of spare HD as follows:

* ~710mb for AVI
* ~600mb for audioless 25 fps AVI
* ~110mb for 23.976fps MP3 audio (or 1gb for 23.976fps WAV)
* ~100mb for 25.000fps converted MP3/MP2/AC3
* ~4.5gb for new MPEG2 DVD stream
* ~4.5gb for new authored DVD from TMPGEnc DVD Author

Good luck - any questions then repost,

If you have 23.976fps source, and want a DVD compliant mpeg, in TmpGenc you need to set 'encode mode, 3:2 pulldown when playback' and 'Frame rate, 23.976fps (29.976fps internally).

Set everything elae how you want it and encode. TmpGenc DVD Author (or any other authoring package) should then accept the mpeg quite happily.
