MAJOR problem with TMPGENC!!

[brian_reilly]

Okay, I download a 66MB .avi file containing a twenty minute video. I use TMPGENC to encoded it as an MPG1 XVCD. 12fps, 700 kbits/sec, 160x120 video.

So it tells me the file size will be about 14MB and takes a little over an hour to encode it. When it's done, I end up with a 219MB file. What the hell am I doing wrong?!

EDIT:: If this helps any, for Motion Search Precision I used "lowest quality (very fast)", and for VBV buffer size I used 30KB (down from 40).

you don't really believe that you can get 20 minutes of video and audio in 14mbs do you?

Did you perhaps mean 140 MB?

Ver. 2.59 of TMPGEnc has a bug that won't let you encode VCD's at anything other than the VCD standard of 1150 Kb/s. It lets you select it then it encodes at the higher rate. Check your version, get a newer one.

Thanks, but I did actually mean 14MB.

There has to be a way to get 20 minutes of video into 14MB. If not using MPG1, then something else. The fact is, the file was only 66MB to start, I dropped the quality almost tenfold, cut the viewing size in half, and ended up with a file that was four times the original size.

how is the avi file encoded?

I've always found ".avi" to be a little confusing because it can mean
anything from raw, uncompressed video to divx or xvid, which is likely
highly compressed.

I can't believe you'll be able to compress this down to 14mb and
have a watchable quality if it's a 66mb file that's already compressed
with one of the mpeg4-type codecs.

you could try the following:
use virtualdub to re-encode the video as xvid

use bbmpeg to encode vbr mpeg1

use tmpg to encode vbr mpeg2

download another version of tmpgenc and try again.

If you try to fit a 20 min file into 14MBs using the MPEG format the end product will look like crap.
You would probably be best using Windows Media Encoder, this seems to be the best way to highly compress videos and still make the end product look near enough watchable.

[Cornucopia]

He didn't say he wanted something "watchable", he said he wanted it 14MB.

Sure, if you make the frame rate slow, the frame size tiny, the color spectrum very constrained, etc., you could then encode to Real or WMV9 or DivX or something (doing the same butchering to audio as well) and be able to end up with 14MB. Don't expect TMPGEnc to be able to do it. It only is meant for encoding MPEG1 and MPEG2 and would be so inefficient at such bitrates (we're talking ~95kbps) that it either couldn't make it as small as asked for, or it would look like garbage warmed over.
Remember VCD rate is just 1150kbps. Thats a 12:1 difference.

We mac guys helped him get it down to 10mb. It's still easily watchable, very little pixelation. Go Mac guys, Go Mac guys

I'm guessing you must have used quicktime format or something? Just curious.

Yeah man. He used the 3ivx codec to create a Quicktime movie.

whats the big deal of 66 megabytes, i mean does he only have like 100 mbs left in his hard drive, or is he making a cd with videos, and there were 14 mb left burrr big deal, plus you would need to use an audio bitrate of about 64 and video bitrate of 32 if you ask me mpeg would never look good at that low quality.

He may have been wanting to put the video an a website or something and had limited space.

[tgpo]

Naw, he said he was gonna put the video up on his website, but wants the smallest file possible for modem users.

None of that means crap as far as MPEG file sizes go. Only the bitrate matters. I wouldn't consider MPEG suitable for what you are trying to do, so I would recommend Windows Media Encoder also.

[brian_reilly]

Yeah, the Mac guys rock! I really need to find a way to do it on a PC though...
