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
How are the results if you process the original video the same way in Cinelerra and Avidemux? Do you still get blocky and flickering video?
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(
There is quite a bit of luma blockiness, too. I doubt the camera original is as blocky as the proxy, by far.
I really like the output of avidemux for both 640x360 and 1920x1080 videos.
As we already have noticed, Avidemux appears to do more than only raise the colour saturation. But what? -- Herman Robak _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
