View Full Version : XviD refuses to encode at very high bitrates

Or well, it doesn't downright refuse... it just decides to use a lower bitrate.

I was encoding some home video to XviD, and at ~1Mbps it still looked a bit meh, so I said what the heck and gave it 12Mbps to fill a DVD.
...buuut the damn thing just won't use 12Mbps! It uses 1700kbps avg... at first I thought "well, I guess that much wasn't needed..." - but no - it's still a bit blocky!

The only way I could solve this is by using constant bitrate or quantizer, but I'd really like to use 2pass VBR.

Why does it reduce the bitrate that much? Using the 12 something Mbps bitrate I gave it, it should've ended up with a 4GB file, but instead I got a 680MB file.

Frustrating. D:

:search:
you saturated it. use a high bitrate quantization matrix.

Thanks :x I found the XviD [PDF] FAQ and within it was my answer.
