Davidwillis - With Avidemux, video choppy, out of sync, etc, sounds like doing a Single-Pass process.
> The 2-Pass mode is there for a reason. In Single-Pass the app can only process each part of the Video - whatever the frame content, or wherever the audio keying is - as it gets to it. That's like a baseball batter not seeing the pitch, or the travel of the ball - then deciding what to do with the ball as it arrives at the bat. In such a case, the hit isn't going to be at all good...
> With 2-Pass - the First Pass isn't doing any encoding or changes. The app is analysing and mapping the Video - which frames have less or more detail and changes from the ones previous - and then those to the ones following. It also analyses the keying, including for audio. It writes this information to a text-file. Then on the Second Pass, it has the "what's ahead and where the keying is" information to work from, so it isn't "guessing as it gets to each frame".
> People in our bunch here, trying to use Avidemux, at first complain about the video being fuzzy or "jumpy", and the audio sync being "way-out".
> I had just that happen recently with a friend who was trying to convert the MOV 640 x 480 from his new Canon camera to PAL 720 x 576 to then write to DVD and play on their TV-Player. We'd discussed the new camera over the phone, and as he knew I was converting several type of camera Video to DVD, asked the easiest way to do it.
> I emailed him step-by-step instructions, like a small Tutorial. A couple of days later he was on the phone saying that his results were very poor - and was there a better app than Avidemux, without buying something expensive (he's a Windowser, like 98% here in Oz.)
> So we went through what he was doing step-by-step. And he was using Single-Pass "because that 2-Pass would take twice as long". I suggested running the instructions again - but using 2-Pass. He did - and rang back an hour later, sounding very pleased with the results...
> With Avidemux - are you setting the Destination AR, if the first result you get is distorted? See Pic1.
> Are you using Single-Pass - or 2-Pass...?
> I've used Avidemux in Windows, in earlier times, and now for a long time in Linux. We convert DVD MPEG2 to AVI, usually Xvid4, sometimes MPEG4, downloaded AVI to PAL 720 x 576 MPEG2 DVD, and also P&S Camera 640 x 480, MOV 640 x 480 H264, and Std HD 1280 x 720 16:9 Compliant MPEG4 (*.mp4 files) - all to PAL 720 x 576 - to play from TV-Players into Std 4:3 TVs.
> So long as you USE the Configurations and Filters functions properly, Avidemux works very well for all of those things. Yes, in Linux - I don't use "other" for Video now, and haven't for several years. PCLOS only, since 2006. (Mandriva / Mandrake - before that.)
