Lousy Windows Quicktime Gamma
This isn’t really a Premiere thing, but I don’t see any Quicktime forums here, so I’ll ask here in case someone may have an answer to this issue.
For years now I’ve noticed that the Quicktime player plays video on PCs with a lousy flat gamma. I’ve looked throughout the settings and haven’t found a way to change it. Worse yet, it applies this lousy gamma to files you render files with QT Pro on a PC, making them look even worse. This is especially so when rendered on a PC and played back on Macs, with their lower screen gamma.
However, this never happens when you render a file in QT on a Mac and play the video file on a Mac. It only happens on a PC. It used to be that you could playback files OK on Windows QT (that were rendered on a Mac), but now even playback files rendered on a Mac will look this way.
Does anyone know how to correct for this? I can’t imagine anyone not having seen this before, for I’ve seen it countless times on countless PCs, but for example here is some screen grabs of playback of the same file on a PC with the Quicktime player and with the V-Lan player:
Thanks for any info on this. -

Gamma correct fields – This filter lets you increase or decrease the gamma of the input video frames. Gamma is kind of like non-linear brightness – that is, the entire spectrum isn’t all brightened by the same amount. The gamma correction range is from 0.0 (completely dark) to 1.0 (the existing level of gamma) to above 1.0 (which brightens the pixels). Gamma correction is usually used to adjust a Mac-authored movie that plays too dark on a PC. A gamma of 1.4 is usually about right for converting the gamma of a Mac input file to the same level of PC brightness. If you have a movie that looks good on the PC and you want to use it on an Xbox, PS/2 or GameCube connected to a TV, then you must adjust the gamma (or the movie will be too bright and washed out). Use a factor of 0.88 to covert from PC gamma to TV gamma.
Hobe this helps you out.
