DivX (PAL) -> SVCD (NTSC) Need help

[lascelk]

Hi all,

I have several DivX (PAL) AVIs I would like to turn into SVCDs. I have been using Avisynth/CCE to do all my video encoding. I use TMPGenc to encode the audio and then to multiplex. When ripping DVDs or re-encoding AVIs (even 24fps) it has not been a problem. On a 24fps AVI I've run Pulldown on the video and after multiplexing, the audio and video were synched perfectly. I tried that with the PAL video source and the audio was way out. I also tried changing the frame rate of the original AVI source (VirtualDub & AVIfrate) but that screwed up the audio synch as well.

I know I can just use TMPGenc to do the whole thing but I am simply not impressed with the quality of the video. CCE is far better. Is there any way I can do this with Avisynth/CCE? Do I have to manually re-synch the audio? If so, how?

Thanks in advance.

I don't think that it's good idea to convert DivX to SVCD. Maybe if you have very good quality 2CD rips.
You need to perform timestretch on audio by factor 25/23.976 to get sync....

Thanks, that worked.

I used CoolEdit to timestretch the audio (actually timecompress). If anyone is wondering, the ratio in CoolEdit to go from PAL->NTSC is 119.88. Also, make sure you select Timestretch, not Resample and use High Precision.

Cheers
