Converting avi to mpg qith TMPGenc...size problem

[welz400]

Hi,
I just converted a 700mb avi media file to a mpg file using TMPGenc.
The conversion took something like 9 hours, and the mpg file is now 3.3Gb in size! The avi file plays for 1 hour 50mins, but the mpg file plays for 5hours +.
How many 80min CDR's will that take and who wants to spend over 5 hours watching the same film???

Help please

Thanks

Filesize depends on bitrate and length of the clip. Are you making a VCD, SVCD or DVD mpeg? What settings did you use?

Your CPU is the reason it took 9 hours.

I suspect your file has bad frames, scan it with Virtualdub.

Your avi file almost certainly has VBR audio, Tmpgenc does not like this and what you describe is a typical result. To check if this is the case, then open the avi file in virtualdub. If it gives a warning about the file containing VBR audio then we are on to a winner. In that case take a look at my second post in this thread https://www.videohelp.com/forum/viewtopic.php?t=181335&highlight=

Yes that is/was the problem....CBR. So I am now going to do what you advised in the link to the other post.

Funny thing is that I used TMPGenc to convert another avi file to mpg, which I burnt to a CDR, the went to play it on my DVD (plays anything) player, but the video stopped after a few minutes, and the audio continued! So I checked the original avi file, then went to re convert with TMPGenc, but guess what? It is now the same as the other media file I want bto convert. It wasn't before??

say la vie!

Thanks for your help
