Avid editors, please read this
I am working with Resolve, and need to bring the materialt back to Avid, without gamma-issues.
I work with RED, normal scale monitoring and render normal range. Like the default work around.
I do import the MXF-files into the bin in Avid with database-drop-in.I do experience huge gamma-issues, clippes highlights and the black level is liftet. I need to compensate doing gamma controls on the upper track in the Avid timeline.
Additional information:
In both Resolve and Avid, the computer monitor shows a pretty flat image. When outputting to external monitor it looks crispy and fine in resolve but flat in Avid.
I do use a calibrated monitor – Oled.
I do move the files from one mac to another.
Any ideas? I have e-mailed both BMD and Avid about this issue for months but they dont have a good answer. Its all about full range vs. normal range, but that is clearly not the issue here.
I would really appreciate if you have some comments, please tell me about your workflow – and if you are experiencing the same.

what are your avid project-settings? 701 or rgb?

Hi, I have tried both. I cant see any difference on my monitor when changing the settings.

and what video-card are you using for avid? i guess bmd extreme3d and avid 6!?

[stig olsen] “huge gamma-issues, clippes highlights and the black level is liftet.”
Are you measuring any of these values with an outboard scope? I’m willing to bet you’d see some interesting numbers.

I have not, but it dont change the fact of the issue. It looks very different on my calibrated monitor.

So the issue would appear to be a serious mismatch in settings in the media handoff. I am working in an AVID-originated project, AVC-HD original, consolidated and transcoded to DNxHD, graded in Resolve, rendered to DNxHD Target mode and sent to Online. We are also exporting plates in Prores for an FX house, which I can re-imbed in the Resolve timeline seamlessly. Some late FX shots have to be re-imbedded in the exported timeline in AVID, but so far no issues. The external FX facility is working with MochaPro and AE, rendering back to ProRes. We occasionally see some incredibly miniscule decoding differences, but for the most part, the whole RGB, Y’CbCr full-scale/Legal Video selection, when correctly configured, works extremely well, no need for conforming adjustments.

Do you output through mojo dx or nitris? I guess Nitris is the only possibility to have RGB output from medicomposer. Do you see any difference between project mode (RGB/normal)? Maybe it has something to do with different graphic cards on the two macs?

Andy: AMC 5.5, signal out through mojo DX.

Hi Stig, sorry to hear that you are having this issues, I work all the time with Media Composer and never had any.
My DaVinci settings are 1080p normally scaled, most of the media is DNxHD 185X or uncompressed 10bit. The AAF export/ import is flawless.
I monitor with Mojo DX and Nitris DX, and now sometimes with the Decklink and no problem.
Woul you upload some clip for me to try with my configuration?

Thank you, yes when Im back in the office.
And to be sure… you are working without any soft clip LUTs that clips the signal to 64-940?
I do work with black to 0 and white 1023. output monitoring scaled and render scaled.
