ML RAW Video Tone Curve Photoshop/ACR Workflow FIX
Basically when you use the Photoshop/ACR workflow to process the RAW DNG folder you have to set working space for ACR to sRGB 16bits which is all fine BUT most people calibrate monitors and TVs to something like gamma 2.2 but you were editing in sRGB and as soon as you take the footage out of something not completely color-managed which includes almost all video playback software you end up with the sRGB video file's sRGB tone response curve not getting converted for use on a gamma 2.2 display and you get the contrast and saturation a trace boosted and the shadows and lower mid-tones become too dark.
The fix is to add a step right before you save out as TIFF in your batch action. Use "Edit->Convert To Profile->Custom RGB" and then rename it to "REC709 Primaries With Gamma 2.2" (or whatever) and hit OK (it should already have selected REC709 primaries and gamma 2.2 for you automatically, if not, make sure it has gamma 2.2 set and REC 709/sRGB primaries set). This will store each TIFF in Gamma 2.2 with sRGB/REC709 primaries instead of in sRGB TRC with sRGB/REC709 primaries so your videos should look the same when played back on your sRGB/REC709 primaries and gamma 2.2 calibrated display as they did when you edited the initial frame in ACR/Photoshop.

Well that makes the TIFFs with gamma 2.2 but AE converting them into a movie file is still going bad, perhaps because I had working space set to sRGB or REC 709 HD. I will try turning working space to none and in the render queue output options setting Preserve RGB and hopefully disabling all color management in AE will prevent it from putting it back to sRGB TRC.

Yes that did the trick. So you need to first do what I said in the OP and then make sure to set AE working space to NONE and in the output render set it to Preserve RGB (no color management). Then when you import into Premiere Pro it looks the same way as it did in Photoshop/ACR (assuming your monitor is internally calibrated to sRGB/REC709 gamut and gamma 2.2 D65m if not there may be slight variations due to primaries in different locations and such although if you at least calibrated it through software the gamma/WB ramp should still work in your video card and that should still match up more or less).
It really makes a considerably noticeable difference. Your video won't end up overly saturated/contrasty/dark in dark to midtones compared to what you thought you had prepared in Photoshop/ACR. If you were fine-tuning in Premiere Pro anyway I suppose it doesn't matter but it saves you from having to re-tune to make up for sRGB vs gamma 2.2 differences which is hard to exactly do by hand and it means less need to push bits around once you are possibly no longer in full bit format.

Oh and first, of course ACR should be set to sRGB working space and 16bits when using it to do ML RAW video (for stills ProPhotoRGB 16bit makes most sense).

For an AE only workflow it should be possible to do it if you can find and .icc profile that has sRGB/REC709 primaries mixed with gamma 2.2 instead of sRGB TRC. I didn't find one with a quick web search, but I'm sure one has to be out there. I think I will just make my own such. Then you could just use that in AE and it should be good (at worst if you used that for the output conversion profile that should force it to work out).

Just adding new info as needed. If I kept re-editing the initial message then people might not realizing it was getting updated with new info and miss critical new bits of info.
Is that something unusual or a problem for this forum
Sorry for trying to put some helpful info out there, yeesh.

A lot of folks seem to have no idea what's going on with respect to the RAW video thing, or don't have a reason to be interested. But some of us are watching with great interest! Keep up the good work!
