Hi,
I noticed that when I render through the pipe, the stream is always yuv420p.
Input #0, yuv4mpegpipe, from 'pipe:':
Duration: N/A, bitrate: N/A
Stream #0:0: Video: rawvideo (I420 / 0x30323449), yuv420p, 1280x720, SAR
1:1 DAR 16:9, 29.97 fps, 29.97 tbr, 29.97 tbn, 29.97 tbc
Now I figured I was probably doing something wrong & double checked everything.
Input file dnxhd 720p yuv422p cinelerra color model yuv 8bit. Reading the
manual I saw that rgb-float is
close to lossless and will work with yuv & is faster in many plugins. so I
tried again in rgb-float.
Same yuv420p stream. So I tried rendering to one of the formats that works
natively mpeg4. The output
file came out as yuv422p. This is with rgb-float as cinelerra's color model.
Same dnxhd yuv422p input
file.
I tried this with both versions of cinelerra I have installed CV, HV-4.4
Is this broken? I looked through the yuvstream patch for 4.4 & it looks to me
like it's setup to make sure
the color model isn't changed. There are comments in it about no lossy format
conversions. With the if
statements checking & maintaining color model.
Anyone have a clue on this?
Thanks,
Ned
