Can you confirm this problem? At first I thought it didn't occur on my regular work machine (dual-core Intel Pentium 4 CPU 3.40 GHz, GeForce 8500 GT), but upon closer inspection, it /does/ occur -- it's just that the problem shows up most prominently in relatively dark scenes. Also, the behaviour is slightly different: Here, the brightness is only correct when playing forward or fast forward, not in any other mode (frame forward, normal reverse, fast reverse). > It could be some subtle differences between CPU architectures, > differences between software routines and OpenGL counterparts, > differences between GPUs, driver versions etc... It would appear that the CPU architecture and the video driver set in Cinelerra's preferences don't make any difference. The only thing the two machines have in common is that they both have dual screens in TwinView mode.
