MAJOR Gamma Shift Between Premiere and Encoder Export

[Duke Sweden]

Try reading my posts! It’s not a problem between Premiere Pro and AME. It’s between Premiere Pro and media players, like VLC. Look at the picture I posted above. Half is Premiere Pro’s Program Window, untouched, footage straight from the camera, and the other side is the same footage in VLC, straight from the camera.

Now, it turns out that VLC has a whole bunch of settings you can use to tweak color, gamma, etc., but they’re so sensitive they’re useless. Just looking at the hue control sends the colors way off.

As for unchecking render in composite linear or whatever it is, that changes my aspect ratio! My video loses width and gets black bars on the sides. So that’s not an option either.

i tested another computer with a colorpicker with premiere and vlc, same result. pixels are identical down to RGB code. i did install a fresh copy of vlc so perhaps try uninstalling vlc, delete its old color preferences folder and install the latest version. I am running win7, premiere 2017.0.2 vlc 2.2.4. make sure your gfx driver is set to 0-255 not 16-235 in utility control panel.

My “graphics driver” doesn’t give me that option. I told you it’s an integrated Intel 3D graphics card with 0 RAM assigned to it. Reinstalling VLC won’t do anything as I get the same result in Quicktime and Windows Media Player.

Here’s what I’m gonna do. This short 8 second clip looks perfect in Premiere Pro. The skin tone is exactly what my skin tone looks like in real life. In VLC it tends towards pink/purple. When I move it more towards yellow, it just adds yellow to my skin tone, it doesn’t “de-pink” it. Anyway, here’s the clip. You tell me, on your professional, calibrated monitors (NOT being sarcastic here) how this clip looks to you. I checked the youtube version to the VLC and it matches so what you’re seeing would look the same to you in VLC.

Please, all of you who color grade and have calibrated monitors, weigh in. It may be my PC and monitor is causing me all this grief and I’m wasting my time tweaking (which I’ve tried many times, both the PC and Intel graphics calibration and my HDTV’s calibration tools)

P.S. View it on youtube. For some reason this embedded version is darker than it should be.

And just to add one more twist to this, I reinstalled cc 2014, opened a file, made some obvious tweaks so I could compare more easily, and sure enough the encoded file matched what I was seeing in cc2014 perfectly. Grrrrrr….

I understand that youtube and vlc match from your previous post. Got it.
The youtube clip does appear a little magenta. I actually like this ‘grade’, looks nice! well anyway, here’s the thing, after you upload to youtube, youtube changes the colors again! I tested some other g7 footage and premiere matches exactly with vlc, again…
Can you upload a 1 sec. clip from raw g7/g4 footage?

in vlc-tools-preferences-enable use hardware yuv->RGb conversions.
set output to openGL video output
in vlc, effects, filters, disable video effects

if this fails , I might be able to make a correction LUT for you. Can you please take this image, open it in VLC, uncheck video always fit windows, zoom original size,
screenshot that and upload back as a PNG. I’ll use that to create a conversion 16&64 LUT you can use in premiere.

How can I upload just one second of an out of camera clip? I’d have to trim it to one second and render it, right?

Those VLC instructions, are those to correct the color problem or a tutorial on how to trim a raw file down to one second? Gonna try it while I wait for your reply.

btw, I’m glad you liked the grade as it appears, but the way I intend it to look is better.

That appears to have fixed the problem (openGL. Previously it was set to Automatic). I’ll have to encode a short video with weird hues so it’s easier to compare. I’ll update shortly.

i need the trimmed raw clip to determine if your camera’s colors are magenta. I’m trying to see if you have many video codecs installed like klite-codec or something and its overriding default colors with vfw etc.

im trying to get your vlc to default color mode.

[Duke Sweden]

But how do I trim it without rendering it? If I render it’ll no longer be a raw out of camera clip. Anyway I’m going out back to shoot some more test video. I’ll shoot a one second clip. I assume you want me to post it to youtube right? Or upload it here in a zip file?

Also, I do have k-lite installed but I don’t think I’m using it, plus as I said changing from “automatic” to “openGL video” seems to have fixed the problem.
