Hello, I am trying to transcode yuv4mpeg into DV - the idea is to use y4mstabilizer to stabilize some clips before editing in Kino. I would like to avoid an intermediate high-compression (inter-frame) format.
So far I had little success.... Mencoder and ffmpeg can output yuv4mpeg, but won't eat it. I only had some "success" with transcode - but the results are very strange indeed! -y dvraw dies with a "Floating point exception", so not useful. -y dv survives the task, but the output looks like this: -in the top half of the frame, two 1/4 size pictures side by side (1/4 by area, 1/2h by 1/2v linear), identical (same channel....maybe Y but shown in magenta/green) -below that, four 1/4 horizontally by 1/8 vertically sized pics side by side, identical (same channel....maybe one chroma channel, but shown in magenta/green) -below that, four 1/4 horizontally by 1/8 vertically sized pics side by side, identical (same channel....maybe the other chroma channel, but shown in magenta/green) -bottom quarter of screen green I use yuvdeinterlace and y4mscaler to 444 before stabilizing, and y4mscaler to 420_MPEG2 after it, feeding the result to transcode. If I watch the stream before trancode with yuvplay, it is perfectly OK. Maybe someone on the list has encountered this problem and solved it? Do I need to "reinterlace", and how to do it?
