I see colour trails on my videos. My card is a DC10_new.
Here's an example: http://www.oxstone.com/misc/200504/image_zoran_trails.jpg...
nice -20 lav2yuv record_01.avi | y4mshift -n -2 | yuvscaler -I USE_744x560+12+8 -O DVD -M BICUBIC | yuvdenoise -F | yuvmedianfilter -T 3 | mpeg2enc -f 8 -c -D 10 -E -10 -q 2 -K tmpgenc -o record_01.m2v
Does those trails come from my tapes? It's an Hi8 Sony Camcorder. The tape is a good Sony tape, and it was totally new when I used it...
I've not looked at your sample, but I've seen similar problems generated
by yuvdenoise. Yuvdenoise averages three frames to get the pixel value.
I suspect (but haven't looked at the source) that it then uses this
averaged value for the first value of the next three it averages, which
gives you trails. This is really noticeable going into a dark scene;
stuff leaves trails.
