Hi guys,
so I finished editing a piece in CS6, Sent it to resolve, graded it, rendered to QT uncompressed, imported back to CS6.
Everything perfect.
Then, I export a h264 and thats when the trouble begins.
The h264 has a very noticeable shift in contrast and color.
Tried to export from RCX, same thing.
Tried to export a tiff from RCX, just a test, same thing.
Tried to export a wmv from CS6, just a test, same thing.
I dont know what to do anymore.
The piece was corrected in Red Gamma 3 and Color 3.
I'm using a windows pc.
Please help, have to deliver this piece this monday afternoon.
Thanks a lot!
 
there are many known issues with gamma in QT/h264. try opening it in vlc and that will tell you alot. otherwise, google h264 or qt gamma correction or shift fix
 
I've run into this issue...Try importing the h264 back into Premiere and if the colors/gamma look correct in Premiere then its just the player that your viewing it in. If you upload it to youtube It will look fine. If it doesn't look right then you have a different issue than I had. Also, try viewing it in Windows Media Player.
 
Gonna do the reimport thing.
I am viewing it in WMP.
Around that Mark.
Maybe use mp4?
Or enconde in x264?
 
Thanks for the time guys, really have to figure this one out.
It's gonna be projected inside an art gallery and its a dear project to me.
 
The only way to be sure is to borrow or rent the projector they are going to use, or take your file into somewhere with that exact model of projector and try it. Bear in mind the projector may or may not have selectable colour spaces. Only when you know the target you're aiming for, can you adjust your film to project correctly.
 
Definitely Eric but my problem isn't really that.
The problem is the difference between the file I'm correcting and the exported h264, on the same monitor.
There is a shift during the export.
 
Echoing what Paul said...

Try opening in VLC....quicktime always shifts the gamma of my h264....
It's most likely the player...not the file

EDIT: you may have already tried the import back into PPRO thing....
 
Ok so this is weird.
I was opening the file in WMP and was having the shift.
Opened in QT and the file is ok!
Wtf?
