Question

Flickering problem when using the "Lighting" adjustment

If I have two video clips playing at once, i.e. a split screen or an overlay for example, everything is fine.  If I use the "Lighting" adjustment on the clip playing in the Video1 channel then also everything is fine.  If I then make a "Lighting" adjustment to the clip in Video2 then the problem occurs .  The clip in Video2 will flicker this adjustment on and off quickly.

I've updated my video drivers to the latest version and also tried with Video Hardware Acceleration off to no avail.   This problem occurs during normal playback i.e live playback and on a export.

All video was shot at 25fps on a Canon 5D mk2 at 1080p.

Project settings:

Editing mode: DSLR
Frame size 1920 x 1080
Pixel aspect ratio:  square
Fields: No fields (progressive scan)
Display format: 25 fps

Version 14.1

Please help!

There can be a difference between what you see in the preview screen and what you get at output.

When you add adjustments, effects, split screens, etc. the computer has to work extra hard to render a "real time" preview.   Depending on the strength and power of your computer, the preview may be less than perfect.  When you Export and Share, the computer will take a lot more time to render a better version. 

Can you Export and Share the section you are working on?  Set the Work Area Bars and check the Work Area Bars only in Export and Share. 

Good luck with your project!

I had never done a split screen project and would like to know how.  So, I set up a brief project in Premiere Elements 15 according to this tutorial:  https://www.youtube.com/watch?v=dcU8D-BC8pA

I was able to apply different Lighting (Brightness) effects to the separate halves.  

Are you doing it differently?

Bill


Yes, the tutorial is how i do it.  Do you get the same bug as me?   If not, would you be able to try setting different Contrast and Black settings on each clip and let me know if the clip in Video2 flickers please?
