iMovie export keeps failing "Application run out of memory"
I have a new Mac with sufficient RAM / memory in total 16GB. But still exporting a simple video using iMovie is failing (short movie of about 30 minutes HD movie). This is not what you expect with a brand new high performance iMac.
The problem seems to be related to: out of application memory (which is ridiculous considering I have 16GB of RAM).
During the iMovie export I get a system message: Your system has run out of application memory.
I noticed that the process VTDecoderXPCService which is used by iMovie is growing to over 60GB of memory.
No other applications are running, sufficient disk space (over 800 GB) and 16 GB RAM.
Application: iMovie latest version 10.3.1 (end of 2021)
OS: macOs Monterey
System: iMac 2021
Disk space: 1TB flash drive, 800GB available !!
Memory: 16 GB !!
I am surprised that this is even possible with a high performance iMac creating a simple movie with iMovie. Bad programming from Apple software engineers? I have not installed any other applications on my iMac.
I would really appreciate any ideas / feedback?
iMac 21.5″, macOS 11.4
