Does YouTube Render Down Colour?

    Everytime I work on a video within Final Cut Pro, I do a bit of colour adjustments. Just a bit to boost the colours to get a little bit of contrast. When I render then export the video everything looks great but once I upload the video to YouTube the colour adjustments don't seem to have been applied or they got rendered down quite a bit. Does this happen to anyone else? The strange part is that I don't get this issue when I upload a video to YouTube that was edited within Adobe Premiere Pro CS5 and my work flow is exactly the same just different software is being used. Another strange thing is that this only happens with footage from my Nikon D90, none of this happens if I use footage from my GoPro Hero HD.

    Here is a little comparison video that I made. Maybe I should do the same thing in Adobe Premiere Pro to see if there truly is a different or perhaps I'm just going crazy

    What do you all think?

    That looks like a gamma shift to me. When you export from FCP, what format/file container are you using? And what about for Premiere? For example, Quicktime has a strange way of dealing with gamma - it's been a problem for years.

    Looks to me like there's a subtle change in the video; it doesn't look as if it hasn't been applied.

    When ready to export, the video format is MP4 in Premiere Pro CS4 and MOV in Final Cut Pro.

    The color adjustment sometimes seems like it isn't applied at all or its just really dull.

    I recently uploaded a little tulip video. I did one in FCP and another in Premiere. Both had colour adjustments but Premiere came out much stronger. After uploading both to YouTube and watching them side by side the dull FCP version looks better but only on some clips. Perhaps I need to master colour correction or maybe try out Magic Bullet Colorista or PhotoLooks.

    Are you checking the files prior to uploading?

    After you export the files, re import it to FCP and compare it to the original.

    Also, are you compressing the file out of FCP directly?

    Perhaps you should export a full res version of an edit (same as source, native codec, frame rate, etc) then use adobe media encoder,compressor or mpeg streamclip to make the deliverable file.

    I have noticed gamma shifts when dealing with exports from FCP, but without seeing exactly what you're seeing i can't be certain.

    Also, have you viewed the YouTube clips on a different browser? And evn on a different monitor? Just curious.. I've seen some weirdness happen with flash and how it displays video,
