How does it look on your compiuter before you send it to Vimeo?
Currently Being ModeratedJan 5, 2012 12:44 AM (in response to Tom Wolsky)
I've been using the 'share to Vimeo' function from within Fcpx so I have only seen my movie in the Fcpx viewer.
What I see in Fcpx looks great but when i watch it back on Vimeo it is darker.
I'm not sure if Fcpx creates a local copy of the shared movie before it uploads to Vimeo. I'll have a browse through the event/project folders to see if I can find one.

It should be in the Shared folder in your project folder.

thanks, I have just tested this out using a greyscale chart, here's my findings:
I used a jpeg of a greyscale bar chart for this test.
The first thing I did was open the chart in Photoshop and measure the RGB values for each 'bar' of the chart with the eyedropper (from black RGB 0,0,0 to peak white RGB 255, 255, 255)
Next I Imported the jpeg into a new FCPX project's timeline and took a screeshot of it in the FCP viewer, then measured the RGB levels in Pshop
Next I shared the project to vimeo, waited for the upload and took a screenshot of it playing back on vimeo and again measured the RGB levels of the screenshot.
Then, (thanks to your help) I opened the 'shared' movie file from my FCPX project folder, played it, took a screenshot and measured the RGB values again.
Here are my results:
The problem is still occurring once my video is shared to vimeo. The RGB levels for the greyscale chart's bars are consistent in everything except the vimeo video.
Basically, the source material (chart jpeg), FCPX viewer and shared file are all the same correct gamma/exposure.
However, the vimeo video does not. It has darker midtones and a slight colour-shift with slightly higher G values than R or B.
Any ideas why or what I can do to ensure consistent colours from camera to Vimeo?
I'll post this on the vimeo forum too.

You could either make everything in the project into a compound clip and adjust the midtones in the color board, which may shift the color as well slightly. Use the RGB Parade to check this. You could also export a master file, take it to Compressor and adjust the contrast in its filters, and use its share function.

Thats the answer I was afraid of
It seems mad that I have to do this kind of correction don't you think?

Did you ever resolve or get an answer to the colour shift problem? I've spent the last 2 days trawling the net and I can't find an even half confident solution. Something happens to the FCPX colour when it goes through any compression but I can't find a solution. Is it just a bug awaiting repair?

You should talk to Vimeo about this. The file is consistent throoughout the production process and after export. Any variation in luma and chroma is occuring in Vimeo.

although the topic is a lil' beyond my skills, but what I would try:
upload the file for comparison twice, in a mov and in a mp4 wrapper.
perhaps, Vimeo still assumes a diff. gamma from an Apple machine (mov), than from Windows (mp4).
I know, that is fixed in MacOS for quiet a while.
but maybe Vimeo's import routines don't know.-
so, they still 'correct' from γ1.8 to γ2.2
… just a wild speculation from an half-informed hobbyist...

Thanks. I am no expert in this either. What do you mean by export in an mp4 wrapper? Do you mean export it as an mp4 format instead of H264? I'll try anything at this stage. Here is an example of what I am talking about.
http://randylarcombe.com.au/vimeotest/content/Screen_Shot_2012-07-22_at_5.29.01_ PM_large.html As you can see it's a significant jump in colour and contrast.

no, exactly I did NOT meant that.
that's why I phrased 'wrapper':
a bit confusing, but there's mpeg4, the codec, and there's mp4 the wrapper or media-container:
• use your .mov you have already exported, which has the right colors.
• download/install the free tool Mpeg Streamclip
• open your mov, go straight to 'save as' and choose from drop down mp4
• save and upload that mp4 for comparison to Vimeo
• (tell us, wether you notice any difference, as said, just an assumption)
What will that do?
your h264 encoded material is actually in a .mov-wrapper
Streamclip unwraps that, and puts it into a .mp4-wrapper
this does NOT encode/transcode/affect your h264 material!
it just changes the box, not the chocolate!
What's NOT working is changing the suffix in a Finder operation - that does NOT affect the 'atoms' of the wrapper = a re-named mp4 will be 'noticed' by many programs/players as a mov anyhow! You HAVE to go the 'long' way with Streamclip - due to the simple re-packing operation, that process needs only seconds
I'm using this process to 'convert' my FCPX/iMovie .mov-exports to a readable format for my son's Playstation3 ... mov is a nogo, re-named suffix is a nogo. only re-wrapping to .mp4 works. excellent.
... but, as mentioned, I do care very little about gamma and luma as an hobbyist, my 'products' are under-exposured and veeery colorful anyhow

It will not allow you to save as a mp4 from that dialog.
There really needs to be an answer to this. Since FCPX will ONLY let you output to .mov straight to Vimeo, it seems like Vimeo would get the hint that some of us are using Macs and fix this STUPID PROBLEM!
Has anyone found a work around other than graded it brighter before posting to Vimeo?

Has there been any more info on this? I just started a similar thread not realizing this was already underway. I did read in another thread here that may have something to do with this.
I wasn't able to open the Technicolor Blog link though.

I have long observed this issue. It happens no matter how my master was made - FCP, Pr, Avid. I have taken to making brighter versions for Viimeo as a matter of course. It's annoying - what you see is not what you get.
