		<description>&quot;My question is, why does Apple has to make it so hard for normal people to use their codec, because it is possible, you just need to go to the apple trailers website, and you have nicely encoded movies in both platforms, mac and pc&quot;

They don&#039;t though, they have the gamma shift problem as well! It&#039;s an infuriating problem.</description>

		<description>Hi there.
I&#039;m also having problems exporting some videos to quicktime using the H.264 codec (Windows), I&#039;ve tried the various approaches that are suggested in the above posts, even the tiff trick, and none work perfectly, the one that produces the best results is still the QT Blend/Transparency/Slider, but unfortunately this disables the streaming. And contrary to what was posted, the tiff trick still washes the colors out. I wasn&#039;t very successful with the QT GammaStrip, from Fuelvfx, didn&#039;t work for me, the movie was the same after applying the gamma strip.

My question is, why does Apple has to make it so hard for normal people to use their codec, because it is possible, you just need to go to the apple trailers website, and you have nicely encoded movies in both platforms, mac and pc. I decided to switch to flash video instead for web video, excellent quality and consistent in all the platforms, and plus you don&#039;t need to install more software, specially Apple software :P And nowadays 99% of the browsers have flash player installed(http://www.adobe.com/products/player_census/flashplayer/).

Bye.</description>

		<description>I tried everything and the best solution for me is the TIFF trick!  Thanks Andrew Steward for posting that.

I tried the following approaches and here were my results.  NoteL I&#039;m rendering out of Premiere on my PC to a Apple Uncompressed MOV file (6GB file for a 3-min reel), then going into QTPro:

1) The QT Blend/Transparency/Slider thing never worked for me (using PC, XP x64, and QTPro 7.6).  It would simply do nothing, even when re-opening the file.  I did notice that it lagged the file&#039;s playback though. So I assume this no longer works in the latest versions of QT.

2)  Tried using x264, but the PC version takes a CS degree to use (which I have and I still couldn&#039;t figure it out).  Tried using the x264 on my MacBook Pro with QT Pro (Intel-based, OS X 10.5.6, QTPro 7.6), but it would crash every try.  Even changed a lot of the settings to try to get a different result.  So no luck there.

3)  Tried rendering out of Premiere to a motion JPEG.  This did work and I was able to render to a H264 in QTPro but I noticed a lot of quality loss due to the double compression.  This is good, but not great.

4)  Finally tried the TIFF trick on my Apple Uncompressed MOV and it works beautifully.  My video looks great!  

Thanks for this comment thread.  I searched all over and was getting really frustrated.  Check out my reel at my website (http://www.rossmenwton.com).</description>

		<description>Zach - How do I install x264 into After Effects or, maybe Quicktime?

I know that it is an encoder that may require meGUI, but I once saw a screen shot showing it as a option in a drop down menu in Quicktime.

		<description>Adjusting the Visual Settings tab is BAD!

Use:
-x264 (can still be viewed by anyone with quicktime7)
or if you can get it to work:
-FUELvfx Quicktime Gamma Stripper software</description>

		<description>Hi all,

I have a quicktime gamma workaround that works for exporting h264s and other codecs that have the gamma shift issue. We use it at work for sending h264&#039;s of telecine color grading reference to some very fussy clients, and so far no complaints :)

The blend/transparency/alpha trick comes close, but the blacks are still a little bit grey and dosent give the same results on both mac and pc. The trick we use has been coined the &#039;tiff trick&#039; and works by tricking quicktime into using default tiff image gamma before an export.

How to do it:

1) Create a small (32x32 pixels or so) tiff or bitmap - dosent matter what color, just make it 8bit and RGB
2) Open a new player and &#039;Open image sequence&#039; and select the tiff/bitmap. set the frame rate to whatever you&#039;re going to be working in
3) Open your desired quicktime in another player, &#039;select-all&#039; and &#039;copy&#039; the clip
4) Back in you &#039;tiff/bitmap&#039; movie hit &#039;add to movie&#039; - this will add the video over the top of the tiff/bitmap on a second video layer
5) Export using your desired codec

All going well the gamma will match your original video very closely</description>

		<description>Thanks for posting this. I was searching for days to find your solution! Maybe you should post this on youtube or other sites as well. Totally worth it!</description>
