Summary: working with masks in a composition with 3 videos,
masked (undesired) areas appears when one image
superpost others.
Product: Cinelerra
Version: 2.1
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: Medium
Component: Effects/Transitions
AssignedTo: [email protected]
ReportedBy: [email protected]
The area hided by a mask of a video becomes visible when it cross or pass over
another masked image.
I have this composition (all multiply alpha masks, all feather borders around
40):
track 1 = i applied a mask to isolate a face in a video.
track 2 = a crowd that i masked to "round" the frame.
track 3 = i masked a guitar playing.
First, the crowd fade in in the bottom right corner. Tree quarter of the video
area is black.
Second, the guitar comes up in the middle left of the video area. the arm of
the guitar is over the crowd.
Then, the face comes up.
Meanwhile, i used the projector tool to reduce the size of the guitar and move
this image to the right top corner.
this the bug (maybe):
From now this movement I can see the edge of the original crowd video inside
the guitar mask. More visible in the border area of the mask of the guitar.
Reproducible: Always
Steps to Reproduce:
Explained above.
Expected Results:
I suppose to have 3 independent images i could move, zoom as i wish in the
video frame.
The bug becomes less evident if I lower the feather of the masks borders, but i
need it around 40, and this video is a big job for cinelerra brazilian
comunity.
Actually, inside the border area of a mask, we see the hidden image of the
video in the lower track instead of black.
