Yes at full frame 1920×1080, I can export and there is no artifacts. I did a test exporting at full frame then importing that file then exporting again at 720×405 and no artifacts were present but I’m trying to avoid that work around.

Hello Everyone,

I’ve been in contact with Adobe and they have shown interest in looking into the issue. I created a sample file along with sending them my Encoder Preset. Hopefully they will be able to duplicate the shift on their end which in turn may warrant a conference call.

The people at Adobe are very busy and I value any time they put towards solving this issue. If it comes to a call with them I will let everyone know the results.

In the meantime, comprise has been my only solution to this issue. I do a lot of render testing and make adjustments as needed. If you scroll up and see my post from Feb 2 that shows the side by side render along with the Sequence Settings panel. I found very significant differences with “Composite In Linear Color” UNCHECKED as opposed to CHECKED.

I started another thread on this topic. I made some head way. Let me know if any this helps.

Hi Dan,

The difference is totally unacceptable but the render on the right is only slightly off from Premiere. The render on the left is completely off and all the difference is that check box i mention above.

Interesting thing I just found. So exploring all the CUDA settings which I thought were all turned off.

I went into the sequence settings and found “Composite in Linear Color (requires GPU acceleration or max render quality) was checked by default.

I unchecked this and did a test render and the outcome had very little gamma shift compared to what the image looks like in Premiere.

Check out the results.

I do have that turned off.

Hi Jon,

Thank you for responding. I also used VLC and the same gamma shift occurs.

My only solution at this point is to adjust the opacity until the render is how my screen displays.

For example, I am also using a red matte that looks great on the screen at 50% but renders looking like 25%, completely washed out. So I adjusted the opacity to 75% and after rendering I’m close to what 50% looks like which is acceptable.

Any other advice will be greatly appreciated.

Thanks for the response. In my case, my nested sequence has all the necessary graphics and blends and works fine. When I bring that nested sequence into my main sequence my blend mode I set to one of my graphics is lost.

Hi Dave LaRonde- Thanks for responding. I tried Chris’s solution first and it worked out for me. I appreciate your input.
