Sorry to reply to my own message. I found this message in the archive https://init.linpro.no/pipermail/skolelinux.no/cinelerra/2006-December/009057.html It is about Xv settings, which can make video displayed via Xv look dark. I tried twiddling with the settings, but they do not make a difference in the rendered output of Cinelerra. This is what I would expect, since I used mplayer to take a look at both the raw yuv stream produced by png2yuv and the one by Cinelerra, and they look different. Xv settings only affect display, not Cinelerra rendering, right? I'm guessing that the gamma for the rendered output is not quite right for some reason. The image is displayed right in the Cinelerra compositor (= look the same as the still PNG original), but the rendered output is dark. Mysteriously, if I read the rendered yuv file back into Cinelerra, gamma/colours look ok in the compositor, even though the same file looks dark in mplayer. Changing the Xv attributes does not seem to affect the Cinelerra compositor window (playback driver is set to X11-XV).
