maybe transfer mode as pin light with a fast color corrector or curve effect(white point/gamma), from effect-track matte luma.

try adobe uninstall cleaner tool as older files probably were not deleted prior to reinstalling. and delete any saphire folders/plugins/registry

to be picky, dropping a 25fps into a 18fps will be super jerky. There is a difference and smoother motion when using optical frame blending which Ae has from 25fps to 18fps. the first method is aken to using the posterize time effect and is very, very jerky.

smoother way-
Choose Layer > Frame Blending > Pixel Motion.

probably the 16-235 color levels not 0-255. you can burn that in with AE’s utility – color profile converter if avid won’t read the color management correctly.

try renderer software instead of cuda. and not adjustment layers either.

Try premiere Lumetri lut out Rec. 709 16-235. that should raise the blacks.

If you knew the gamma, that would help as well. It’s usually 2.2

or:

1. calibrate your monitor to one or the other.system preferences>Displays) to 1.8
2. use gamma tags legacy and in quicktime properties enable FCP legacy
3. Final Cut Pro/System Settings/Playback Control. Change Gamma Correction from

Accurate to Approximate
4. fcp individual clips – Editing tab, “Imported Still / RGB Video Gamma”. choose

source 1.80, 2.20
4. use icm or luts to counter.
——————-
some further thoughts…

you can setup your monitor profiled at gamma 1.8/2.2
You should think about editing your working LUT to your native monitor gamma.

If you want to stick with gamma 1.8, continue reading.

1. for playback, QuickTime preference, General tab:
“Enable Final Cut Studio colour compatibility”

2. in AE,
Choose File > Project Settings. “Legacy Quicktime Gamma” preference via render

queue, not export

3. there’s quicktime 1.8 iluts in speedgrade/premiere as well.

enable max render quality.

2k will require faster disk speed unless you take advantage of premiere’s new proxy function.

honestly, h.264 isn’t bad if it isn’t overly compressed with long GOP. intraframe should work fine.
the other issue you would run into is if you used a lightly compressed codec that is insanely large, thus creating a hard drive speed access bottleneck.

I recommend testing. You can try also try quicktime photojpeg. constant bitrate might improve playback and render time because they are the same number instead of VBR. you can also try exporting out a DnxHD then encoding with handbrake which might create more compatible playback with your device.

If you have a simple PC to DVI-RGB, then it might simply be the playback software. for windows, I recommend MPC-HC as its smoother than VLC and requires less CPU overhead.

try rolling back to much older driver. this issue is across many cards.361.75
