I think there might also be another problem. I suspect in threaded preview
gen mode, if you scan each item in playbackbox quickly and all have no
preview image, then they all get launched simultaneously.
this can cause excessive resource usage, esp on a remote FE with network
usage. if 10 are generating images, then you get 10x network usage during
avf initial stage where it works out what the recording is.
Is it a good idea to only ave one preview gen going at any one time per FE
or perhaps shift preview gen to the/a backend as a job like commercial det
