Exporting for CAD / ADSTREAM / DUBSAT etc...
Hi guys, 1st time post here so I appologize if this has been thrashed about before...
A. Is H264 a YUV codec, and does it support timecode?
B. If A is "Yes" am I better off clamping color and luma in any RGB graphic content BEFORE entering FCP or should I trust the CC tools in FCP?
C. If A is "Yes", for client preview copy (not broadcast) on computer monitor should I then change the gamma back to something that better represents the video for the computer screen?
I presume that H264 is good for all different types of source material given its popularity, just can't imagine a YUV codec being so widely used??
Alex.

Hi alexmotto
in answer to your question H.264 can be a YUV codec
and it can support timecode. If you are sending files to the services you mention in your heading get a current codec list for Standard Definition from them. They all support high profile transport stream MPEG2. This format is good because it is not 'wrapper dependant' like Quicktime or AVI
That being said I'd give them a Quicktime over an AVI.
As a rule they wont care about timecode - just total duration of the file. So they will expect a 15 second TVC to be exactly 15 seconds in duration.
I think you are better off trusting the CC tools in FCP.
I'd leave the gamma as it is. If you are creating your client preview copy in Compressor you could make it brighter with the gamma correction filter if you like.
If your client wants a timecode burn again this can be applied as a Compressor filter.
H.264 is used for a huge variety of things and comes in a lot of different flavours. The HD broadcast flavour is awesome but you will need a transcoder like Episode Pro to use it with control.
H.264 deals with colour space using 4.2.0 and 4.2.2 rather than RGB and YUV. Web based H.264 like you see on the Apple website for movie promos uses main or baseline profiling - 4.2.0 and the HD broadcast type will use 4.2.2 or high profile H.264.
The current Quicktime player has not helped matters.
Try using the radio button labelled Enable Final Cut Studio color compatibility. Its cosmetic but will even out perceived image darkness or uneveness in playback.
As always when in doubt check your file on a broadcast TV monitor.
Hope this helps
