Seems like the RAM-issue is solved (4 x 9k-stills, one aftrer each other and no RAM-Warning).
Nevertheless i do experience some Sync-Errors with chunk-size at 50MB.
With the size at 50MB 2 of 11 clients get the error (Always different ones)
If i increase the chunk-size i.e. to 100MB even more clients get this error.
I then decreased the size to 12MB and had no errors.
The Sync-errors seem to always appear right after a new pass is beeing started.
In the console it looks like the following:

It would be great if there will be a solution where we don't have to fiddle around with this values every time, since it's a bit time consuming
Anyways, thank you for your great product, that i don't want to miss anymore ;)
