they are very much alike, but I still prefer the 5dtorgb. especially the 1.8 version
but more importantly, when 5dtorgb is used to convert into 4444, it makes a huge difference. i have no idea why, i’m just processing the same file into both 422hq and 4444, and seeing a large difference in the image. transitions are much smoother with less noise.

i clicked the box in qt7 as you suggested. but still no luck. however i’m happy now that at least i can convert using “quicktime conversion” and my output comes out very similar to what I see in fcp.

my plan is to move this file into QT7 to convert into a vimeo format.

is there a drawback to this? i usually just exported with current settings and then moved into QT7

thanks

You’re right, I’m not sure if my monitor is 444 capable. It’s 12 bit, but is meant for photography and not video. so not sure beyond that…

Sorry James, read this one as well. https://www.elskid.com/blog/5d-to-rgb-the-follow-up-bigger-comparison-yes-yes-prores-422-sq

In any case, I made my own tests converting to both 4444 and 422, and I can see a clear difference on my calibrated Eizo 211 monitor.

You mention that 5DtoRGB is free. Is there a paid product that does a better job at converting? If so, could you let me know the name?

I had a discovery. When I export using “Quicktime conversion” from FCP, then there is no gamma shift. When I export using “Quicktime ” from FCP, there is a shift. Seems like a bug to me. Or there is a magical setting somewhere…

Actually not. Try converting a file into 4444 and 422, look side by side, and you will see a major difference. At least I can with my footage.

Thanks Rafael.

My footage comes from 5D, converted using 5DtoRGB. I’ve tried your method but it didn’t work. I get the same gamma shift as before. Did you have any other suggestions?

thanks!

Where is the FCP color compatibility box in QT?

I am not doing a QT conversion, so not sure how that relates. I am simply exporting the sequence with “current video&audio settings.” When I do the same kind of export with ProRes 422 footage there is no shift. So I don’t feel this has anything to do with my monitor/hardware.
