To fix your audio / video sync problem, try to convert the video to 320x200 (or whatever you need) with 15/20fps with audio intact. I use "Any Video Converter" for that.
Then I strip/convert the audio with VirtuaDub to wav and then I convert the video to 15Bit RGB.
See if that works.
To see if your video is in sync with audio, open them in any player and compare times.
The problem with forcing ftp to 15 or 20 fps (by the way the two shows I have gotten working in good speed with real classic Amiga, their ftps are higher than 20 fps, some of them 30 fps), is that in some cases it is completely out of synch between audio and animation. Whe nI use VirtuaDub it says in order to have fps synch with audio you need to use 24.998 or in some cases 23.782, depending on the actual video. So I enter these numbers in frame rate setting myself, I disable audio, save mp3, convert mp3 to 8 bit, save it as wav, set rgb to 15 bit, save as a new avi file, rename it as ren.avi and ren.wav, use avi4hv, it says do you want to use fps 24 (which is not 23.782 or 23.9998), I say yes...and continue from there.
Now I just wish the actual program avi4hv itself does use float instead of int when it comes to fps. However, I got two ren and stimpy working correctly so I am happy...I think (I may be wrong) got the hang of working around this...I am not so sure myself. I will do another one now...and if it works as I hoped then I will post an update here saying I have managed to get it working 100% and should easily be finishing off ren and stimpy series to move on to family guys, then american dad and whatever tv show I have (prison break, etc) before moving on to movies.
Then I will burn all my work on blue ray disc. However, I still have issue sharing it with you guys...maybe you guys could help me get in torrent so you guys could download it in torrent program (I use utorrent myself in Windows). I just do not know how to share it in p2p in torrent community. If someone can give me a tutorial it will be great.
But...I have another problem and that is the quality of the video and dithering issue...it is some what low end quality, I kind of want it to make it better quality than this....can someone give me tutorial in how to improve my work? I will not of course redo the previous work..what is done is done..but for future work I would love to do them better.
