Hi there,

 

I've been web searching, but not found any successful answer to the problem of light Quicktime exports... i.e. when I export my sequence and then look at the resulting QT file everything has gone milky.... all too light...

 

Apparently this is an internal problem with the conversion to QT

 

 

 

My flow is this:

 

Macbook Pro OS X 10.6.8 which is running FCP6

 

Exporting footage sequence from the timeline directly to a QT file.

 

I use QT conversion.

 

.h264 codec

 

Data rate is restricted to 5000 so that it's ready for Vimeo - this auto sets it to high quality

 

1280x720 HD 16:9 frame

 

 

 

Is there a solution to this?

 

I have seen various suggestions of things, but nothing seems concrete or very sure.....

 

 

 

Will using sequence settings to render in RGB / YUV or YUV high quality make any difference to things? How do I know which of these to use?

 

 

Many thanks for your help,

 

Dan

    Dan,

         Do you have "enable final cut studio color compatibility" checked in your Quicktime prefs, also "use high quality video settings when available".

    Hi David,

     

    Thanks for the swift response!

     

    Wow, there's definitely a good improvement in colour matching with the 'enable fcs color compatability' option ticked so many thanks for that...

     

    But, there still seems to be a major discrpency between what I am watching from my rendered timeline and the export version.....

     

    Any other ideas?

     

    I just did a few tests including another suggestion I saw of using an adjustment of the Coloursync and switched it from photos to gfx, but that made no discernable differnce to the export..

     

     

    I do find the issue is more notoiceable if I have done any colour adjustment using the inbuilt FCP effects options such as the 3 way correcter...

     

    Thanks for your help,

    Just done an additional test.... viewing same exported clip in QT and mpeg streamclip

     

    Viewing my exported .mov file using mpeg streamclip - everything looks great.....??!!

     

    So..... how do I know how my video will look when viewed by other people? Or when posted online? I most commonly use Vimeo.....

     

     

    Plus I've now seen reference to Safari / Firefox etc seeing videos in different lights..... ***?!

     

    How will I ever know if someone views my video and it looks good or looks like trash?

     

    Anyone, anyone..... Bueller... Bueller??

    You can't. You have no control over whether it is viewed on a trashy $100 screen with the settings all over the place or a perfectly calibrated high end display. Just as there's no control over what TV is used by a consumer receiving a broadcast signal.

     

    All you can do is use your scopes to make sure the video is in spec and looks good on your equipment.

    Well, there is a bit more to it.

     

    There ARE reference standards.

     

    To get there you need a qualified output device (AJA Kona, Blackmagic Decklink, Matrox MXO) feeding a real reference monitor (eg FSI LM 2340 or LM 2461).

     

    With this kind of a setup you can be certain of how your material appears. Otherwise, it's just a best guess ...
