I have been trying to figure out how to improve my encodes. Some are great, but most leave something to be desired. Namely a crisp, stable picture. I tried to change Q factor to see if it helps, but it will only change on a 1-pass vbr, which would seem to be bad quality.

Someone told me to do an ecode with different bitrates and select the lowest bitrate that would keep the Q factor close to 10 for a good non-pixelized picture, with the program bitrate viewer. I was wondering could I just encode a portion of a vob file of the movie so it doesnt take so long, do the 1-pass, then get my averages from that, then set up for a 4-5 pass vbr?

But then, how will i be able to change the Q factor when I do 4-5 pass vbr? Or does it automatically adjust with the bitrate goes up or down?

Thanks

I dont know who told you this. Q facter is not used when you do more then 1 pass. I dont know for sure what it does but it has something to with how big you file sizes will be. When you do more then 1 pass DVD2SVCD is uses something else to determine the size of the image files.

If you want to only encode a chapter then click on the movie length dropdown on the conversion tab and then select what chapter you would like to do there.
