4.12 P3 HDR movie export totally broken

UPDATE: I can reproduce it every time, even in a new project:
If you check “Capture frames in HDR” at the export window. Then it will crash.

Crashes all the time when I try to render a sequence to movie.

I don’t know why but UE4 4.12P3 started to give this error when I try to start a movie export from the sequencer. I exported movie yesterday well and I worked all day, and today I couldn’t export the movie due to this error. I am not really knowing why is that.

The game window appears and it starting to capture, but on the first frame it is giving this error:

Is anybody experiencing the same problem in 4.12 P3?

I have an exactly same error as you

Thanks for the check! I hope it will ring the alarms and Epic will find a solution for this. This is a very important feature for us, filmmakers :slight_smile:

Oh My God!!

Hey sdasfasd,

Thanks for reporting this, I’ve entered it as UE-30978.

Hello sdasfasd

Did you try in Unreal Engine 4.12 preview 5?
It works in my machine.
Please try in it and hope you have a good result.

Best.

The fix for UE-30978 did, indeed, make it into Preview 5. Happy Sequencering!
