[Chimera-users] movie quality

I see that Chimera daily builds are incorrectly giving the option
"-qscale 8" to ffmpeg, the program included in Chimera that does the
movie encoding. The "-qscale 8" conflicts and apparently overrides the
"-b 5000kb" bit rate setting you requested. Both Chimera 1.5.3 and
daily builds use qscale 8 which is variable bit rate encoding if you do
not specify bitrate. Recent changes to Chimera movie defaults broke the
movie quality handling. I have fixed it. The fix will be in tonight's
daily build, dated Jan 5 on the download page
Thanks for identifying the problem.
