PC. If I export to H.264 (.MP4), FLV or MPEG2, there is no gray-white problem. However, I need to export to MOV in this case. Is there any workaround for this? What is the explanation for the problem?
With the problematic MOV, these players play it without a problem (white is always white):
- Media Player Classic Home Cinema
- Windows Media Player
- iTunes internal player
These players display white in graphics as RGB 237-237-237 and white in video as 255-255-255:
- QuickTime Player
I would like to understand how this is possible. How can the graphics contain same color as background in one player but different in another player? Surely there is just one layer on the video file, right?
I am producing my video for a studio with their specs and I should know what is going on in the video I send them. Thanks!
I found out more about this. First the remedy:
If you are using Windows and an NVIDIA card, you may see weird gray instead of gray. And weird patterns within the gray may appear, also the difference between white and gray will be difficult to understand. Today, this happened to me on QuickTime, VLC, and "Media Player Classic - Home Cinema".
Go to NVIDIA Control Panel -> Video -> Adjust video color settings. There you have Dynamic range Limited. Change that to Full 0-255. The gray will change to white!
I still don't understand exactly how, as explained in my first example/question, the white #FFFFFF box could turn to gray while at the same time the filmed white background was still white (even when the limited NVIDIA setting). It is as if there can be some magical white with a hidden parameter which would override the NVIDIA Limited Dynamic range setting. To me both whites seem to be #FFFFFF but somehow the Limited Dynamic range setting reveals otherwise.
