anything imported into premiere gets forced converted to rec. 709 gamma 2.2. so you’ll need a lut transform.
see what the post house wants. jpeg2000, mxf, xyz color, gamma 2.4, white point D65, D63 etc…premiere’s wraptor DCP only accepts rec. 709 gamma 2.2, D65 so you’ll need a lut for it. or you can use easydcp, dcp-omatic
if you do it yourself, make sure you use the right color primaries
DCDM XYZ D63 (6300K, 0.314, 0.351 white point) gamma 2.6
RGB color space parameters
Color space White point Primary colors
xW yW xR yR xG yG xB yB
DCI-P3 Theater 0.314 0.351 0.680 0.320 0.265 0.690 0.150 0.060

set your graphics card video control panel output to 0-255 from 16-235. did it look ok in AE?
finally,
if its a bug somewhere, don’t worry, just send a HALD image via dynamic link and create a ‘repair’ lut with free IWLtap lut creator. -
if you do have a calibrated monitor, you need to include that calibration lut inside premiere, even if its rec. 709. premiere ignores .icm color profiles. You need it as an iradas .cube LUT in a lumetri adjustment layer.
-
you probably aren’t calibrated to rec. 709. you’re probably P3 or adobe RGB. you need another lut on top of the slog3 lut. this is to convert your P3 calibration to rec. 709.
-
doing a 2nd pass with noise reduction separate from lumetri often helps

you could check your autosaves. but if you had no autosave or incremental backups, and wrote over the file with the same name, it usually acts as a low level wipe, but sometimes easus data can recover it or you can have a working temp ~ file, hard to say.
-
sometimes you can add motion blur with reelsmart motion blur or timewarp. shutter should usually be 1/ (2 * fps). 24fps with 1/200th shutter can look jerky compared to 1/48th shutter so fps doesn’t always directly align with judder, although they are heavily related in a panning sense.

everything premiere imports in, becomes rec. 709. as such, you should use the sony 3d luts that convert S-Log3/S-Gamut3.Cine to rec. 709 gamma 2.2. This way, premiere sees it correctly; then dynamic link should work just fine. If going from AE, you can use color profile converter or apply same lut in AE before going to premiere. make sense? icm’s and luts can do the same thing.
-
dynamic link is forced converted to rec. 709 gamma 2.2. if you don’t have that, you need to use either a conversion lut or ae’s utility profile converter. color management doesn’t work across dynamic link.
-
to get around this, you still need display color management enabled. as long as
your working space is the same as your monitor, you don’t need simulate display,
but its a bad idea if your working space can’t be the same as your monitor. It’s bad practice if your working with pro-photo for example as you need to work in the largets gamut of the largest item in your project to avoid color clipping.-mercury transmit is forced to rec. 709. as is dynamic link!
-try setting the lut as adjustment layer transfer mode color or saturation, not normal-i don’t know why youtube won’t do the re-touch fix or why the lut crushes
it too much, but there’s an easy fix for you.make a custom lut.
upload a color chart to youtube, take a screenshot from your browser. open it and the original in photoshop. make its size the same as the original. place inside the enlarged canvas a HALD from iwltap and click edit-match color(be sure to select ignore the HALD when it automatches!) finally, use that converted HALD to create a custom lut for yourself.
