Hi

Have some problem working with 4k AVC1 video in Pinnacle Studio 24 Ultimate.
Using 'Pan and zoom' to add some keyframes and then the program stops and crash.
Video playback of the source file is lagging but the sound is ok.

Temporary workaround is to export the video to HEVC and work in the 'old' variant of 'Pan and zoom'. 
Work in progress with Corel support but adding this if anyone experienced a similar problem.

/Regards
