problems with gordianknot

[JMH]

Donno what it is but for some reason the bitrate of the finished file isn't what I want. The first pass seems to be fine but the second pass XviD stops at 1500 when I have made the setting for 2500. Tried to experiment and adjust the setting in Gordian knot to 3500 but still no different.

Tried everything now but it doesn't listen to me. I use the same setting like all other files I encoded and there have been no problem so far...

Hi-

The chances are that it's used all the bitrate it can handle for your given settings. This is sometimes referred to as "saturating the codec". The movie looks pretty good, doesn't it?

One way to avoid this happening is to run a compression test before doing the encoding. If you get results of around 100% or over, then there's no way for you to achieve the file size/bitrate you want.

Either be happy with what you have, or if you insist on making it larger, you can use a higher bitrate matrix (hi celtic_druid), use a higher resolution, not use B-Frames, use a sharper resizer, don't use any unnecessary spatial or temporal filters, etc.

But again, run a compression test next time to make sure you can get what you want. It only takes 10 minutes or so. You might also start saving your first pass file. You can't make the second pass file any larger than that first pass file. Might as well keep that one.

The quality is good but it feels wrong to have a different bitrate on the file than the rest >_<

But I try do the settings you told me about. Thanks for the support =)

Bitrate is just a number (a quantatative measure) and is often not a true indication of the quality (a qualitative measure) of the file without consideration of frame size, source, and compression techniques / codecs used.

Maybe a 1-pass CQ mode with Target Quantizer of 1 or 2 would be more suitable ?
