Gamma Shift Prob (Exporting DVCpro Timeline to H264)

[Paul Jay]

P60 is only nice when you play back 60 frames.
For the web you end up loosing half of you frames anyway.
So identical on vimeo is impossible in terms if smooth 60p movement.
Have you tried creating a h264 in compressor?

You know, come to think of it I am not exactly sure why it is DVCpro 720p….the Timeline is in 23.98fps and the frame rate in the browser is listed as 23.98 / DVCPro HD 720p60….what does that mean? Should I have done some converting before I began?

Sounds like you have it set correctly, Panasonic cameras shoot at 60FPS and flag every 24th frame for capturing – so the codec will still read DVCPro HD 720p60 even though the footage was captured at 23.98FPS.

In Quicktime’s General Preferences do you have Enable Final Cut Studio Color Compatibility checked? If not, this could be why your H.264 isn’t showing up with the correct gamma.

Okay, ya i was just reading about that in the manual. I am really an amateur with the HVX.

in regards to the QuickTime Preference Settings—This is were I am really in a jam. While transferring fcp to my new computer I guess quicktime X never realized fcp was there and thus QT PRO never activate. I made a really dumb move and deleted QT X thinking that I would easily be able to reinstall it from Apple….turns out I can’t do that or install QT7 from online (cause it thinks QTX is still there) and my snow leopard disc is a thousand miles away.

– is this QT pref setting something that works into FCP or is it something for QT exports?

– My deadline is basically tonight — is anyone familiar with any other programs that might help me get around the gamma issue so my footage doesn’t get washed out (loss of black definition) when uploaded to Vimeo???

Thanks so much to everyone for the help.
Really Really appreciate it.

Quicktime 7 still comes installed, they just moved its location to Applications > Utilities > Quicktime 7.

I wouldn’t worry about deleting QT10, it’s a stripped down POS compared to 7. Just set 7 as your default for all video files, download Perian, and you’re set.

I just posted about this on another thread, but have you tried the x264 plug-in, and using it to set the gamma flag properly?

You could also try my colorsync filter idea I posted about here:

I haven’t tested it too much, so I kinda consider it to be “beta” advice.

Hope this helps,

Just went to the apple store and they reinstalled QT 7 and QT X for me. Went into the options of QT 7 and enabled the color capatability option, exported a new video out of FCP, looked fantastic (no blacks turned to greys) on QT X abd QT 7, uploaded to vimeo…got the gamma shift…looks like crap.

….is this something I should take up with Vimeo?

Thanks to everyone for all the help thus far, i am getting really close.

Hi Alec,

I mentioned this is the other thread I linked to, but I think you should leave the color compatibility option turned OFF in QT player.

All it does is change the way your video is displayed. It doesn’t change anything under the hood, so to speak. So if you want to see how your video will appear on most end users’ computers, leave the option off.

Have you tried setting the “2.2 gamma” flag using x264? I would also check your movie on a windows box, if you can, before upload.
