Thanks for your hints, Herman! I use that down-scaled video only as a proxy. When I set up the project, I render the final video from 1920x1080p videos. The original 1080p clips were recorded on Canon 600D with Magic Lantern, bitrate was set to 0.7x to save some disk space:
Stream #0:0(eng): Video: h264 (Constrained Baseline) (avc1 / 0x31637661), yuvj420p, 1920x1088, 30516 kb/s, 23.98 fps, 23.98 tbr, 24k tbn, 48k tbc When I tried your trick with blurring the U and V channels, it helps with the block artifacts a bit, but it is still not as good as avidemux and when I set the blur radius too high, color from small spots like the yellow from sea-marks vanishes :o( I really like the output of avidemux for both 640x360 and 1920x1080 videos. Is anybody able to improve the code for 4:2:0 -> 4:4:4 conversion in Cinelerra? Another option would be doing the color correction in avidemux and then load the clips in Cinelerra. But it is not very convenient :o( Michal On 17 January 2012 22:05, Herman Robak <her...@skolelinux.no> wrote: > På Tue, 17 Jan 2012 21:26:51 +0100, skrev Herman Robak > <her...@skolelinux.no>: > > >> I still see a lot of flickering blocks in the top of the image, >> though.
