Bug ID: 425918
Summary: Extracted frames anti aliasing when using effects
Product: kdenlive
Version: unspecified
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Video Display & Export
Assignee: j...@kdenlive.org
Reporter: secretagent0...@gmail.com
Target Milestone: ---
Created attachment 131251
--> https://bugs.kde.org/attachment.cgi?id=131251&action=edit
Attachment contains example of extracted frames of rotated and zoomed images
SUMMARY
When extracting a frame from part that has applied some effect on it (I checked
for Rotate and Position and Zoom), it seems like there is no anti aliasing,
rather, each pixel takes the color of a pixel that would be nearest to it when
effect is applied. This is easier to reproduce with an image (See attachment).
STEPS TO REPRODUCE
1. Load image
2. Rotate or Zoom
3. Extract frame
OBSERVED RESULT
Extracted frame has rough edges around objects (see attachment).
EXPECTED RESULT
Edges of objects should be smooth, and in fact, when you render project as
image sequence you get smooth edges, so extracting a frame should just do for
specific frame what rendering image sequence does for the entire project.
