Fix QuickTime Gamma Shift

Using mp4 or h.264 when compressing through QuickTime can make the final video look washed out. This is a common problem that seemed to have no solution… until now. The gamma shift can actually be fixed inside QuickTime Pro without re-compressing your video by simply changing a few settings.

Scrimski at CGtalk.com posted a good walk-through. Thanks!

SOLUTION: After rendering into a QuickTime/h.264 file, open it up in QuickTime and select “Show Movie Properties.” Highlight the video track then click on the “Visual Settings” tab. Towards the bottom left you should see “Transparency” with a drop-down box next to it. Select “Blend” from the menu then move the “Transparency Level” slider to 100%. Choose “Straight Alpha” from the same drop-down and close the properties window and finally “Save.”

In a few weeks many videos will be updated to the correct gamma but I though I would pass along this great tip.

Works great when viewed in the quicktime player, but does this actually change the video file? When viewed in VLC or uploaded to vimeo, the gamma appears to be same as before. It's driving me nuts! Any other fixes?

Hey Andrew. Big fan of yours and this site. I tried this method when trying to solve gamma shift with H264, but it doesn't seem to have any effect. Are there any other solutions that you, or someone else has come up with? I see that you posted this back in 2008. Surely someone has come up with a solution in 5 years time. And why is it that it's working for some of you, and not others? Anyone? Beuller? Anyone?

yes, it works but it's an unsatisfactory hack because it severely degrades performance and you CAN'T re-save an MP4 in QT-Player...

I followed all the steps and it doesn't change anything. I even enabled FCS color compatibility and that only makes it worse. Can someone please help, because I can't take any more of this stress
3 years ago
This H264 fix works, I've been doing it for a while now, but you get the same results by just choosing movie properties, highlighting the video track, and then just choose 'Straight Alpha' in the transparency box. You don't need to do the blend thing with the slider. And then just save the Quicktime file on top of itself. Andrew's way might be more correct in some way, but looking at two movies side by side I can't see any difference in quality at all.

Hey Andrew, great solution! Thx so much!

QUESTION: The video FPS has dropped and is very choppy AFTER exporting (I do not mean stream playback). Also, it doesn't seem to retain the darks when using another player such as VLC. In the end I just want to upload to YouTube, so I wonder if the darks will hold or not.

Hi -
and thanx for continuing to host this tip using QT to correct gamma issues with .mov's and mp4's.

I could use one for wmv's avi's and other file formats as well

In searching for solutions, i found this post by Adobe:

ProRes 4444 colors and gamma shift when working with After Effects CS4 and Final Cut Pro.

and their solution:

If you use Apple’s new ProRes4444 codec with After Effects CS4 and Final Cut Pro, you may notice a gamma shift (i.e., colors will seem to have too much or too little contrast) when you bring the movies rendered and exported from After Effects back into Final Cut Pro.

To avoid this gamma shift, you’ll need to edit your After Effects CS4 QuickTime gamma rules XML file. This will add the appropriate gamma tag to your QuickTime files on output.

The XML file is found here:

[hard drive]/users/[user name]/Library/Application Support/Adobe/Common/MediacoreQTGammaRulesCS4.xml

Using textedit.app or a similar text editor, add the following line to your MediaCoreQTGammaRulesCS4.xml file:





‘ap4h’ is the 4cc code for ProRes4444. You’ll notice that the XML file already includes entries for ‘apcn’ and ‘apch’. These are the 4cc codes for the older flavors of the ProRes codec.

Once you’ve made this change, you should be able to round-trip ProRes4444 media between Final Cut Pro and After Effects without experiencing a gamma shift.


Here is a direct link as he also goes into fixing it using AE CS3 in the comments section:
http://blogs.adobe.com/toddkopriva/2009/12/prores-4444-colors-and-gamma-s.html

and for AE CS5 users check this link given by the same:

[ProRes 4444 and ProRes 422 in After Effects CS5".]

TWEAKED SOLUTION: After rendering into a QuickTime/h.264 file, open it up in QuickTime Pro and select “Show Movie Properties.” Highlight the video track then click on the “Visual Settings” tab. Towards the bottom left you should see “Transparency” with a drop-down box next to it. Select “Straight Alpha” from the same drop-down and close the properties window and finally “Save.”
This will fix your gamma issue, but it could make your playback choppy.
If so, re-open movie properties, under “transparency” select none. Re-save, you should still have your fixed gamma, but now your movie should play silky smooth again…
Worked for me anyway!

What nobody seems to be talking about is the LAST portion of this tip, when you're supposed to SAVE the settings. I can't believe I'm the only one, along with another fellow a few posts above me that's having an issue by being unable to save it back to MP4... I mean yeah, if I was probably having an MOV container INITIALLY then I'd save it back to MOV, but I have an MP4 that I can open in Quicktime, follow all the tips, but not able to save it back to MP4. The only options are given seems to be MOV.. and both aren't even in megabytes, but in kilobytes..that's useless.

Any help?

Note that this fix will cause the quicktime file to stutter at full screen playback. This 'gamma shift' appears to be more an issue with graphics hardware acceleration and is actually a black level boost rather than a gamma shift. Dual screen users can see the shift switch off when the player is straddled between screens. I'm sure Apple considers this a feature...

Hey...I have also been tortured by this for a long time, and I really find it a bit odd that I haven´t seen posts about what I discovered today posted other places....anyway (on mac) the adobe media encoder, makes perfect h264 encodings in the quicktime container (CS4) At least both VLC and Quicktime plays it back with same gamma as the original...and for that I am really happy. Only thing I was a bit nervous about was the fact that it encodes it about 5 times faster than quicktime does...though the end result seems to match the Quicktime encodings just fine ( and with a correct gamma:)

This is a good fix for PCs, but it is flawed when returning to OSX.

Ultimately I believe Steve Jobs refuses to allow QT to work properly on PCs, even if you pay him $30 for QT Pro. This fix works well on the PC side, but once you export the video and watch it on OSX, you see nothing is improved. The gamma is tweaked when exported from the PC and the result is very dark. I'm guessing OSX is trying to overcompensate for the 1.8 gamma settings, but instead it results somewhere around 2.4-2.6

Interesting thread. I'm on a PC, and have problems converting H.264 from my Canon T2i with Procoder 3 for smooth AE editing:

No matter what format I encode to, I get a shift in the dynamic range - the blacks are lighter, the whites are darker. I guess this relates to gamma? Any ideas, as to how I should try to implement the tips in this thread?

Thanks - kind regards,

"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"

Hi there.
I'm also having problems exporting some videos to quicktime using the H.264 codec (Windows), I'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't very successful with the QT GammaStrip, from Fuelvfx, didn'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'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.

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'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'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'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 ).

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'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 'tiff trick' 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 'Open image sequence' and select the tiff/bitmap. set the frame rate to whatever you're going to be working in
3) Open your desired quicktime in another player, 'select-all' and 'copy' the clip
4) Back in you 'tiff/bitmap' movie hit 'add to movie' - 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

You can download an x264 encoder for Quicktime that is separate from the default Apple encoder, and produces better results faster. It's still h.264, but a different implementation of the standard.

Hey Andrew and Co...

there might be another way to solve this problem, at least it solved it a few times for me now:

In the render settings / output options, go to the color management tab and check the box saying "Maintain RGB" (I'm not sure it says exactly that as I'm using a german version of CS3...). That way it doesn't mess around with color profiles and there is no way to interpret it wrong. Worked for me. I didn't check it on TV screens, though...

Take care, everyone. :)

Thanks for posting a fix to this annoying problem.

The one trouble I still have is that when I render out a video with hinted streaming to be viewed in a browser, performing the gamma fix in QT seems to remove the ability to stream, causing the video to take ages to download before it plays. I've messed around with the streaming settings in Quicktime a little bit, but haven't been able to fix it.

Because on our MACs we have no real issue with washed out h.264 files having produced nearly 50 TVCs in this codec.

@ Kevin (June 17th, 2008 at 1:49 pm)

Try to encode a h.264 in QuickTime Pro out of a Motion JPEG (100% quality) encoded mov. For some reason, the gamma shift (which seems not to be encoded "hard" into the videostream but rather as information on how the movie will behave when played as far as I know) will not occur this way.

BE CAREFUL:

If you have quicktime 7.1.5 [which btw, is practically useless as a standalone player] you must ignore the fact that it appears not to do anything at first.. but it does change it when it closes and you re-open the video!

BTW, anyone know the best version of quicktime for a windows XP user?!
I know AE CS3 requires 7.1.5 for QT .h264 [which if you don't need to load QT files in your AE proj for some reason, you can use Core AVC instead which has a simply fantastic and easy to use .h264 encoder] but I have so many problems playing .mov files with QT 7.1.5!!

Hey Andrew,

Thanks so much for the tip on this. How can you get around this at the encoding-level, instead of the work-around at the 'playback-level'? Do you happen to know? You mentioned that all your new encodes will fix this gamma-shift... was wondering what needed to be done for that to happen? In other words, since most people won't know about this quick-fix within QT player, how can we encode our h.264's so they display properly without shift for everyone else? Thanks a ton!

Hi Andrew!

Thanks for that tip!


By the way, what operating system do you recommend (XP or Vista) as the most efficient with APremiere and AE?


Good luck!

It's actually a Core Video issue, and something that Apple hasn't address properly for over a year.

VisualHub users can circumvent the problem by selecting "Force: FFmpeg Decoding" when compressing H.264 material.

StaxRip and MpegGUI are great Windows H.264 encoding solutions that also don't exhibit the issue on files they produce.

Hey, are you going to the Cine Gear Expo at Universal Studios?

http://www.cinegearexpo.com/

I will be going on Friday. I think Redrock Micro will be there. I'm looking forward to seeing that adapter you were talking about awhile back.

Now that you have had that adapter for some time, how do you like it?

Andrew, do you remember? It was June 17th 2007 - exactly one year ago - as you made the first blog entry. We even saw a comment from your mother. It was an informative, entertaining and just awesome year!!! Thank you and good luck in the coming year!

Sorry I am a bit on a rush right know, so I'll keep it brief:
Well, this will fix the final output slighly, but will not work (correctly) for every movie.
The trick is much more simple: Render your footage as Motion JPEG and convert this to h.264 inside Quicktime Pro. This will avoid the gamma shift at all. Try it. :-)

    I actually prefer exporting as Motion JPEG as it bypasses a lot of the issues with h264

I get some strange results when using those sliders. It's like the sliders don't react in real time. Once I move it over to 100% it takes a few seconds and then it goes white.

If I wait after I change it back to straight alpha, it goes back to the video once again but looks no different. ???

Here are my results: http://i54.photobucket.com/albums/g109/Bonesone4/Picture1-3.png

Pretty much the same right?

    The correct fix is to "enable FCS colour compatibility" in QTpreferences.

Ahh, thanks for that tip Andrew. Been wondering why h.264 renders look more washed out than other codecs. Finally a way to fix this!

Awesome, thanks for the tip.
I'd previously just increase the contrast levels in Quicktime Pro, but I'm glad there's a more suitable way to fix it.
I wonder why Apple haven't provided an update to fix the problem? I mean, it certainly effects a hell of a lot of people.

That is spooky...I just had to export some h.264 files and noticed that problem...I did a quick fix by compensating by +5 contrast -2 Brightness in the AE export. It sure is a bad way to do it but nobody noticed!...good to hear it is possible to do within QT Pro...Thanks man.
