Hi, Generally larger absolute values are more expensive to code than smaller ones. Different coding methods for coding delta QPs are involved and part of the reason for this behaviour...

You seem have the right idea. I think you ran into a bug. I had a look at some code and I see at least one issue in our rate-distortion...

Is this any better after the latest commit? Other bugs are probably still present. One additional issue might be the resolution of your input video since not height or width...

Hi, I guess you mean you are seeing tile borders since you talk about mosaic. Rate control in Kvazaar is not particularly smart and it seems to be broken with...

Hi, Thanks for the example files, they are very helpful. There seems to be multiple things that throw the rate estimation off. Therefore Kvazaar runs out of bits to use...

Hi, I ran some tests with 3x3 tiles and 1080p video with adjusted bit rate. Here are some tips for the current version of Kvazaar: + First to most important...

Hi, Never tried to do this so myself. There is the MCTS Extractor in the HEVC reference software (https://vcgit.hhi.fraunhofer.de/jct-vc/HM/-/raw/master/doc/software-manual.pdf?inline=false) but Kvazaar does not implement the required SEI messages for this...

Hi, Had a (very) quick look at this. Your problem is probably related to encoder_encode(): ```c /* ... * After passing all of the input frames, the caller should keep...

Hi, have you tried using the --bitrate option?

I looked at the code, it looks like the bit allocation is made currently only on frame level as you implied. I don't think there is a reasonable way to...
