That's not much to work with.
Can you tell us a bit more, like what your Project Preset is, the full specs. of your source footage, the exact Export/Share settings used, and then where you are judging this gamma increase?
This ARTICLE will give you tips on how to gather some of this info, and background on why it is so important.
Good luck, and we'll be looking for the details,
I agree with Hunt. If you're using a standard video source (i.e., not a Flip camcorder or still camera that shoots video) and your project preset matches the source there is no reason that your output video shouldnt' be identical to your original video.
One of the things that comes to my mind is that some MOV Exports fail to correctly set the gamma flags for files correctly. That issue has been covered in several threads about a year ago, in the PrPro forum.
Until we know the particulars, anything that I mention is but shear speculation, and probably not useful.
Thanks so much for helping us!
Here is more info:
Camera: Canon EOS 7D
Shot in: 1920 w 24 frames/second
Editing Mode: HD 1080i
Timebase: 29.97 frames/second
Frame Size: 1920/1080 (16:9)
Pixel Aspect Ratio: Square Pixels (1.0)
Fields: No Fields (Progressive Scan)
Share Settings: Mobile Phones and Players (same problem occurred with AVI)
Presets: iPod and iPhone High Quality
Problem: Output brighter, more washed out than what appears in the Premiere Viewer (See attachments)
NOTE: the differential is much greater (ie lower one is way brighter) on the player than in these small pictures!
This is how it looks when OUTPUT TO MP4 (too bright ie, slats showing in background, etc) independent of player (ie same problem within iTunes, etc).
Thank you very much!
