breaking up vcd mpg file from TMPGenc

[romulys]

I converted an avi file into MPG format using the VCD template.
I expected it to break up the output file into 650 MB sections but it didnt so i have a 1.2 gig mpg file. I opened it and segmented it in virtual dub but it only has ooption tosave as avi. Does anyone know how to segment a mpeg and save as two mpegs, keeping correct format for VCD. Does anyone know how to set TMPGenc to save in 650 MB chunks

No, you can't preset TMPGEnc for filesizes, but it's rather easy to use as follows:

This can be easily and precisely accomplished using TMPGEnc. Under the "Files" dropdown menu, click on "MPEG Tools" and select the "Merge & Cut" tab. Once again, make sure to change the mode to "MPEG1-Video CD". Load your file and enter a new (.MPG) name in the "Output file" box. Then doubleclick on the ORIGINAL file's name in the window, which will bring you to the cutting area. Select your desired start and end points for the first half, click on "Okay" which will bring you back to the first window and generate (in a sequence of three automated steps) the first new file. To create the second new file, repeat the steps starting with "Then doubleclick on the ORIGINAL..." (be extra patient with the second half, as the program has to do more seeking to establish the beginning of the new file)

To make sure you don't loose quality, do the chopping in AVI format using Virtualdub. If you chop after converting to mpg, you loose quality using TMPGEnc - not TMPGEnc's fault. Using Virtual dub, chopping is done with direct steam copy hence no decoding/encoding required.

To know how much of avi to chop, use the time scale instead. A VCD will hold about 70min of video hence chop at the 70minute mark. Save as AVI and then use TMPGEnc to convert the chopped avi to VCD.

I have used this method for all my home videos. I tried the TMPGEnc technique too and suffered loss of quality.

Good luck.

"you loose quality using TMPGEnc "

That is utter nonsense. Using "Merge&Cut" under TMPGEnc's "MPEGTools" does absolutely NOTHING to alter or diminish the quality...

Why does the file size reduce at a significant percentage when you put an mpg file through the process without actually cutting anything out?

Are you, perhaps, not changing the default "MPEG1" mode to correspond to the file type that you're working on (SVCD, VCD, MPEG2)?
