chadandreo Posted October 28, 2019 Share Posted October 28, 2019 I was wondering if anyone could help me with an issue I am having with Canon Log footage from the 5D Mark IV. In Premiere Pro, when I add Canon's Canon LOG to 709 LUT to the footage from the 5D, the highlights are completely blown on and the image is very contrasty, even though everything is perfectly exposed. I have tried the LUT on low contrast indoor scenes and high contrast outdoor scenes and the results are the same. Does anyone know what I am having this issue?

Michael Steiner Posted October 29, 2019 Share Posted October 29, 2019 Maybe you took the Canon Log2-LUT by mistake? For Canon Log1 or Log3 I normally use the Log to WideDR LUTs, either: - BT709_CanonLog-to-BT709_WideDR_33_FF_Ver.1.1.cube or - BT709_CanonLog3-to-BT709_WideDR_33_FF_Ver.1.1.cube If one of those blows your Highlights maybe it's a setting in Premiere (wrong Colorspace or something like that) that causes you issues...?

chadandreo Posted October 29, 2019 Author Share Posted October 29, 2019 I made sure that I used CanonLog which is Canon Log 1. I am using Version 2.0 Luts and I do not see those two you mentioned. Maybe version 2 doesnt work well with the 5D? Which color space do you recommend? Also, I just added a couple of screen-grabs with scopes. Link to comment Share on other sites More sharing options...
Michael Steiner Posted October 29, 2019 Share Posted October 29, 2019 This is what a Screenshot of your Grab with the lut BT709_CanonLog-toBT709_WidDR_33_FN_Ver.1.1 looks like in FCPX. Not great, but neither blown out. And it's just a screen grab from a screen grab... So I assume the lut should look better on the original video. You find it in the official lut-package from the C200 support page (i assume it's the same in other cameras support pages?): folder path: 3dlut -> 33grid-3dlut -> full-to-narrow-range That specific lut is attached... I tried a 2020-to-709 lut too and it gives the blown out highlights. So maybe your premiere project thinks your original media is in 2020 color space if this happens with a 709to709 lut? I'm not too familiar with the Adobe suite so can't help you with how to possibly fix that...

androidlad Posted October 29, 2019 Share Posted October 29, 2019 You're clearly using the wrong LUT. The latest official Canon Log LUT pack from Canon website is "canon-lut-201902.zip" and most of them are tagged version 1.1 or 1.2. And if you use "CanonLog-to-BT.709_BT.709", yes it'll clip like that, this one does not have any tone-mapping. Use the one with "BT.709_WideDR".

I download the most recent LUT pack from Canon last week. I tested out the following LUTs: - CanonLog_10-to-BT709_FF_Ver.2.0.cube - CanonLog_10-to-WideDR_FF_Ver.2.0.cube - BT709_CanonLog-to-BT709_WideDR_17_FF_Ver.1.1.cube - BT709_CanonLog-to-BT709_WideDR_17_FN_Ver.1.1.cube This is the final result I got using PP Lumetri. I think it looks good, but I am not 100% happy with it due the amount of artifacts and noise at base iso, but I was able to correct those issues using Neat Noise. 1 hour ago, Michi said: This is what a Screenshot of your Grab with the lut BT709_CanonLog-toBT709_WidDR_33_FN_Ver.1.1 looks like in FCPX.

Let me test out the different color spaces and see if it makes a difference. Link to comment Share on other sites More sharing options...
