Summary: Fading in and out a .PNG in one track causes a ZEROED
track to be brifley seen
Product: Cinelerra
Version: 2.1
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: Medium
Component: Effects/Transitions
AssignedTo: cinelerra@???
ReportedBy: leandroribeiro@???
When there are two video tracks in wich the bottom one (track 1) is a video
file with the fader at ZERO, and the top one (track 2) is a still PNG image
with a black background, using keyframes to fade in and out of that PNG image
causes track 1 to be briefly seen, although the fader is at ZERO.
Reproducible: Always
Steps to Reproduce:
1. Create a project with two video tracks. Colorspace must be RGBA or YUVA.
2. Track 1 is at the bottom. Track 2 is at the top.
3. Add a video file to track 1. Set track 1 fader to ZERO.
4. Add a .PNG image to track 2. The image must have a non-transparent
background, like black or gray.
5. Use keyframes to create a fade in and fade out with track 2.
6. Play the result.
Actual Results:
You should briefly see the contents of track 1.
Expected Results:
You should not be able to see those contents.
This does not happen in colorspace RGB or YUV.
