![]() I have then enabled each effect and set the effect so that is doesn't effect the clip, so I have set the Camera Blur to "0". I have disabled all the effects using the option in the top left of the effect (FX). From that I have added 3 effects, one is a non accelerated 8 bit effect (Camera blur), The next is a non accelerated 32bit effect (Neat Video Reduce noise"), an accelerated effect "Gaussian Blur". That produces the sequence with the bars and tone. I then right click on the new bars and tone clip and select "New sequence from clip". With the above screen shots what I have done is created a new "bars and tone" from the within the project tab (right click "New item" > "Bars and Tone"). I'm using inbuilt bars and tone from premiere pro to do the test so that I can discount whether it's imported footage. I'm also testing whether disabling my gpu and setting it to software causes a colour shift. I'm testing whether non accelerated effects do a colour shift. Is it possible for Non Accelerated Effects be applied automatically without me knowing? If so, is there a way I can stop that from happening? While similar, I have the color shift occurring even when I start new projects and import brand new footage with no effects attached to it.īut I am open to the possibility that this is a solution. I have also exported the project and it gets the colour shift." The preview renders are set to cineform 10bit yuv 10bit 3840 x 2160. I have also rendered these out to make the red line go green and set the sequence to max bit depth and max render. These aren't limited to only 8bit effects either, I have tried with 32bit effects like neat video and still get the colour shift. Non accelerated transitions also produce the colour shift. So an example is setting the camera blur effect to 0, in theory the effect should do anything to the image however toggling the effect on and off shows the shift in the waveform. This colour shift still occurs if you lower the effect so that it doesn't effect the image. I think if you haven't applied a non accelerated effect to your work recently you might not have noticed the colour shift. I'm not on a Mac but on a PC and it sounds very similar to the issue I have been having. I have tried it on two different machines and the same issue occurs. "Hi I have had a similar issue in particular when I have upgraded from 12.0.0 to 12.1.2, it seems to occur when you apply non accelerated effects and the timeline goes from the yellow bar to the red one. ![]() This was a comment that disappeared as I was replying to it that mentioned a similar issue when Non Accelerated Effects were applied to the sequence. I also created a GIF to better demonstrate the difference between footage in Premiere and the same footage routed through After Effects.Īfter Effects displays the colors correctly. This problem might be specific to Premiere on iMac Pro systems. I have tried the same video on an iMacbook Pro computer with updated Premiere and AE. I am looking for a solution inside Premiere so I don't have to create AEcomps for every clip. When the footage is in a sequence, I can create an After Effects Composition, and the color returns to normal. I have not added any effects and there are no master clip effects added. What was properly exposed footage looks like it has crushed blacks and blown out whites. When I import my footage into Premiere, it seems contrast is being added to it. ![]()
