Perhaps this is because the AVCHD is marked as full color range. I might need to revert part of this change. I will look into it.

If you run "ffprobe -i the.mts" against your AVCHD clip, does it report colorspace yuvj420p or just yuv420p?

Fixed in git commit 06ead5b

Thank you!

Hello again. Now I start working with kdenlive and I found that performance degradation still exists (some frames drops). It works faster with latest git. But with reverted c48ed74 kdenlive works much faster.
Info about my video clips.

Sorry, but it is doing something more correct now because the colorspace is yuvj420p instead of simply yuv420p and thereby fixes a bug. You can see about how to tell the camera to not use the full luma range or in the Advanced Clip Properties, you can override it and turn it off.

Ok, thank you for explanations.
