So I am trying to edit a project, but every time I put a transition in it seems to flicker or flash kinda ruining the effect. I can't seem to find a fix for this anywhere so I thought I would start a discussion and ask if anyone knows how to sort it. I've left an example of what I'm seeing.
Only installed it yesterday, so I don't think it's the preferences as I haven't messed with them. My graphics card is up to date and working fine with everything else.
I have the same problem. A screenrecording, on top a black color layer with 80% opacity, masked with a rectangle. This layer comes in with a simple cross transition and it flickers (only the incoming transition). Tried several things like only software rendering or deselect "composite in linear color" in the sequenz settings. Also deleted media cache. Nothing helped.
The only work around I have found is to render as a Quicktime file. I was previously trying to add a simple cross dissolve transition over a PNG image. When rendered as an MP4 I get the flickering on the image from the transition. Really frustrating - have seemed to try everything suggested and nothing fixing issue..
I have exactly the same problem. The solution given by @Stage83 didn't work for me. When trying to play the Quicktime file after exporting I don't see anything and when I import the Quicktime file in Premiere Pro it has the same flicker.
The only workaround that I found was that the problem video and effects was actually b-roll over an interview/studio recording. By replacing the "A-roll" with a fresh clip (same piece, just re-laid), it took care of the glitch. It's not taking care of the problem of there being a glitch, but at least it's a workaround for the moment (until the next glitch). I may find that I have to lay in ALL of the effects in the B-roll befoe replacing the A-roll.
I was having this problem just now and couldn't figure it out! I do all of my colour grading in adjustment layers and they didn't have the same cross dissolve affect applied to them that my clips had which meant there was no transition between the adjustment layers causing the footage to look like it was flashing!
I repeated my cross dissolves on my adjustment layers and this solves the problem
The flickering you see is probably related to a "render order" scenario where the math isn't working on an effect the way you'd expect. A transition or intrinsic effect (scale, rotation, opacity, etc.) might not take precedence over an effect that is added to the clip(s) either directly or by way of an adjustment layer.
The technique for placing effects out of order to achieve a certain look is to nest clips with certain effects, then add that additional effect to that nest. You also found that duplicating the transition also worked as an effect by adding it to an add edit on the Adjustment Layer. Great!

What worked for me is using an even number of frames for the transition duration. I had my default video transition set to 5 frames and the problem persisted. I changed that to six and every single one worked fine.
