I'm using the svn version of cinelerra, and the cvs version of
mjpegtools. I render my project from cinelerra (original footage is
ntsc-dv in a quicktime-for-linux container) as a yuv4mpeg stream. The
aspect ratio is set in cinelerra to be 4:3, but I see that "mplayer
-identify" on the resulting yuv file gives me an aspect ratio of
1.36:1 and "head -n 1" gives:
YUV4MPEG2 W720 H480 F30000:1001 Ib A10:11 C420jpeg
Neither of these seem correct. I am seeing black bands of ~5 pixels
on the top and bottom (ie "mplayer -vf crop=720:470" removes them).

This seems to be the case, as it also ignores the interlacing in batch
rendering (fixed by a pipe through yuvcorrect). Is there a similar
workaround for the aspect ratio?
