Once a segmentation sequence is created, is it possible to apply a threshold or other segmentation effects to all frames. Not frame by frame…
Yes, but you need to write a few-line Python script for this, which iterates through the sequence. You should be able to find everything what you need in the script repository. If you cannot figure out something then feel free to ask here.
If users will start to ask for some segmentation sequence editing operations then we may create Segment Editor effects or modules with a GUI to implement them. However, we have been only getting a few one-off requests.
