I´m playing around with the save to movie node, trying to change the video quality in the format parameter on the fly. Can´t really seem to get it to work.
Am I doing something funny here? Or is this a feature, ie is the format parameter only read at the start of the recording?
Any feedback appreciated!
The format is only read at the start of the recording. (It's a constraint of the underlying macOS framework we're using for movie recording, AVFoundation.) Hm, we should mention format in the node's documentation, in the paragraph about "Certain characteristics of the movie are determined when saving starts, and can’t be changed while saving is in progress…"
Were you just experimenting, or was there something specific you wanted to use variable bitrate for?
