Auto Color Correction not working on AMD 7950X

Hello

Whenn i press the Auto button in Premiere for auto color correction, nothing happens, except maybe the render bar for the sequence goes red, but nothing more.

Whenn i try it on my Laptop it works perfectly fine and auto corrects the color of the clip.

In my PC is a Ryzen 9 7950X and a RTX4090

In my Laptop is a I7 11800H and RTX3080 Laptop GPU

Both Systems run newest Win10 and Premiere.

Thanks in Advance

Correct answer StruchiBoiii

I have a big Update - i got it working

by

uninstalling my gpu driver with DDU (Display Driver Uninstaller)

updating the chipset driver for my motherboard (dont know if that helped)

fully uninstalling adobe with that uninstall programm they have

i then reinstalled creative cloud and premier and now it works

i think its something with my PC itself, i also noticed it laggs whenn scrubbing through footage and i just tried to convert a file with media encoder and it told me i have no hardware encoding available, which it told me yesterday too and i got it working with a restart

HEVC is a compression scheme.  These "mezzanine" formats are uncompressed:   ProRes, DNxHD/HR, or GoPro Cineform.  I mainly work on the mac so I prefer apple prores...  for proxies is use prores proxy....   

Here's the wikipedia page for HEVC

https://en.wikipedia.org/wiki/High_Efficiency_Video_Coding

This stuff can get complicated, but mpeg formats do not contain the full information for each frame but merely every 15 frames or whatever and the inbetween frames simply record the differences between the previous frames and the upcoming frames.  This allows for very small file sizes, but requires much greater processing power...    I've attached a screen grab from mediainfo when I've dropped a iphone video file into it and viewed it in the text mode

As far as I know, DJI footage is constant frame rate but is so heavily compressed that it's usually a good idea to transcode to a mezzaine format or use one of them as a proxy format...

I know this stuff is complicated, but ya really have to deal with it to work efficiently...

How do i know if they would be compressed? I dont think footage is compressed whenn 1 min is nearly 1GB

No with that it does find it, i can drag the clips into Premiere no problem, but it doesnt find them with the media browser of Premiere, but with a bit older footage it does find it.

Well wich format would be better for editing?

StruchiBoiii, not familiar with that drone.    I'm sure that the original files are heavily compressed.  DJI drone footage certainly is...  If you got the clips in premiere, simply right click on the clips in either the project/bin or in the timeline and choose reveal in finder...   As to why they work ok on the laptop and not the desktop, I have no idea, but converting to contant frame rate (if they are variable frame rate) and transcoding to a format better suited to editing, or work with a proxy workflow will probably solve your issues.  Post back with any further questions.

They were shot on a Autel Evo 2 Drone and no they are not constant framerate, steady 30fps.

Tried MediaInfo but it cant even find the files in a folder and the clips surely are uncompressed.

Still wonders me why it works on my Laptop no Problem but not on my PC.

pixel dimensions and the hevc codec require extreme power.   First, what were these clips shot on?  If they're from a screen recording, the problem may be that they have a variable frame rate.. which can cause intermittent and unpredictable issues.  Here's how to confirm the diagnosis and fix it


use mediainfo to determine whether your source is variable or constant frame rate
https://mediaarea.net/en/MediaInfo/Download
if it's variable use handbrake to convert to constant frame rate setting the quality slider in the video panel to maximum or use shutter encoder https://www.shutterencoder.com/en/ which allows you to transcode directly to prores or other mezzanine formats.

 

If that's not the source of the problem, it may be that you need to transcode to a "mezzanine" format that's not compressed like prores...  Or investigate a proxy format.  Happy to go in to more detail on these suggestions if you want.

what are your source properties and sequence settings?  Select a clip in the timeline or bin, right click and choose properties...  and tell us what it says...  and make the timeline active and go to the sequence menu and choose sequence settings...   Just trying to get some basic info that might give us a clue...  might not...
