PAL 5.1 audio to NTSC 5.1 audio

redfive19 · 14th September 2004, 21:39

I have a PAL 6 ch surround audio I want to convert to 6ch NTSC audio. I have already converted the video from PAL to NTSC with Main Concept (I never fully got how to do it in CCE). I just don't want there to be that much loss in the audio. I used HeadAC3he to convert it to PAL MP2 and I can load that in Main Concept but I doubt this is the way to go. Thanks in advance!

well I figured out how to do this in besweet but when I transfer the frame rate to 23.976 fps, the audio is delayed against the video. someone suggested NOT to transcode it to 29.97 but if the video's running that fast, then it would seem that's the only way to do it. any ideas?

With PAL->NTSC (assuming progressive source anyway), you just re-encode as 23.976 in CCE and then run pulldown on the file.

Anyway, if you've done it this way, using besweet's 25->23.976 frame rate change should be fine. I know from experience

It's best to do this operation with AC3->6 wavs and then use a commercial AC3 encoder (softencode, surcode, acid plugin, etc) to re-encode those wavs to a 5.1 AC3.
