Avi>Panasonicmpeg encoder>easy CD=duff VCD please help!greenspun.com : LUSENET : Video CD : One Thread
I have a PIII 500, and am using a All In Wonder Pro to capture AVI at 25fps, I then use the Panasonic stand alone encoder to convert the AVI to Mpeg this seems to work fine and gives a good quality mpeg that plays on the PC.
However when I usw EZCD or Nero to burn the VCD the lip sync trails of towards the end until it's about 1 second out over a 60min VCD.
I contacted Panasonic who told me to look at the properties of the captured AVI as it was probably dropped frames that caused the problem, I used Adobe Premier to examine the AVI and it told me that ther was one dropped frame (is this enough to throw the audio out by 1 sec?) apparantly I can re-create the AVI using Premier to replace lost frames, but as this is a very time consuming process by the time I re-encode to mpg and burn to CD I just wanted to know if anyone else has had this problem, also how do I recreate using Premier as I don't want to screw this up again.

i had a simiular problem and emailed panasonic about it. THEY TOO TOLD ME IT WAS DROPPED FRAMES AND TO TRY TO ENCODE USING A HIGHER DATA RATE(MEANWHILE IM ENCODING TOP AT 3000). So what i end up doing, is using the dvmpeg program i demux the item, then remux it and save it as a video cd perfect(still qualitfies for a regular vcd dont worry) this resync up the sound perfectly

An easier way is to use VirtualDub to process the AVI. Load it in, select the option to change frame rate so that audio and video are of same length. Save the video out. Works fine. VirtualDub is an excellent free program, I don't have a download address here, but it should be easy to find.
