HI.
I am building my first 4k after effects project. Im making some test to export the video and Ae crashes every time i try to render the comp. Any thoughts? Thank you
Do you have Multi Processing on? Turn it off and try to export again.
I’m in front my Ae so i go to test it. 
Not a problem with multiprocessing…but.i ve noticed its a h264 codec issue.ive choosed photojpeg and it seems works. At least dont crash at this moment…
Oh yes, image sequence is always the way to go, especially with long renders PNG Sequence with Alpha channels always work. You can even import them back into AE as sequence and it will be treated as if it’s one big video.
thanks buddy :–)
h264 does not support 4K resolution so Photo Jpeg is a good option.
Best regards,
Andrey
