Problems encoding smaller files/and not losing video quality

[jcjambond]

I ripped and mpeg'd a my blue gender anime movie. I currently have a 987 mb mpg file that i created from the vob files. I found the settings options on tmpgenc to use the Xvid and Divx 5 encoders that reduce file size and permanently add the subtitles to the output file, but now the problem is that in order to get a smaller file output of about 300mbs, i change the bitrate to about 200kbs, which gives me a not so great video quality. I've also tried this with Virtual Dub and the same thing. I want to avoid super huge files, and still keep most of the video quality, any suggestions?
Plus I also can't get VDub to find the filter settings for permanently adding subtitles.

The lower the bitrate, the worse the quality I am afraid that is just the way it is. Some codecs compress better than others so for example for the same filesize you could expect better quality from divx than you would from mpeg, but when comparing the same codec obviously a reduction in bitrate is going to result in a reduction in quality. Also TMPGEnc only creates mpeg files so I don't know what you mean by : I found the settings options on tmpgenc to use the Xvid and Divx 5 encoders that reduce file size. If you want to create a divx or xvid use vdub as you have mentioned, but dont convert to mpeg first, the less encoding you do the better, as each encoding process will introduce an inevitable loss in quality.

I'm confused? Do you want your final video to be a DivX file, or MPEG (to burn to x(S)VCD or DVD)? It appears you want to make a DivX file? If so then why did you encode to MPEG first?

If you want DivX, just encode directly from the VOB files (ie. d2v) no need to lower the quaility by first converted to MPEG. Prehaps a program/suite like Gordian Knot (http://www.doom9.org) might be a good choice for you.


If you wanted to back up the DVD to a x(S)VCD or DVD, there's no need to convert it to a DivX at all. And there are several guides (to the left under auhtor) to make VCDs with subtitles.

Remember, TMPGEnc can make AVI and BMP, JPG sequence files by selecting File-->Output to File...

You are right, sorry , been such a long time since I did anything other than create mpegs with TMPGEnc that I forgot. I have used it for wav files but never avi's.

ok, lets say my goal is not to burn a disk, i just want the mpg or avi file(w/subtitles), if i have vobsub installed, a separate .sub/.srt file for subtitles, will i be able to make a onetime encode from the vob files, directly to a mpg or avi output, and permanently add the eng subtitles to the output file? So Tmpgenc, Gordian Knot, Virtual Dub, Dvd2Avi, can all do the subtitle thing with the first encode or no? If so, I could't get the subs to encode with tmpgenc from the d2v files, they were only showing up in the preview screen after an mpg file had been created first.

tried G-not, but am a little confused as to when i'm supposed to use Vdub with it, at the very end of all the Gnot process, or do i even use it at all, and whats all this stuff about creating a first pass log, and second, I don't even see Xvid guide for G-Not, just divx 3 and 4. i had gotten as far as the video smart cropping, and then save and encode options, but do i then encoce on Gnot, and Vdub?
