Bug ID: 431250
Summary: Rendered videos containing images are ingoring Exif
data for image rotation
Product: kdenlive
Version: 20.08.2
Platform: Microsoft Windows
OS: Microsoft Windows
Status: REPORTED
Severity: normal
Priority: NOR
Component: Effects & Transitions
Assignee: vpi...@kde.org
Reporter: irw...@gmail.com
Target Milestone: ---
SUMMARY
When adding an image containing Exif data for rotation, it should be correctly
rotated in all areas of the application as well as the final render. The
images are correctly rotated in the Project Bin and timelines, however when
rendered out they are in their original non-Exif rotation (i.e. rotated 90
degrees). This requires users to have to strip out the Exif information
manually and re-adding the updated image into the project bin under a new file
name, as simply replacing the image doesn't seem to tell Kdenlive to re-read
the orientation data from the source image.
STEPS TO REPRODUCE
1. Add a jpeg image to the Project Bin where the camera that took the photo was
rotated onto the side (i.e. 90 degrees rotation).
2. Observe that the photo in your file explorer shows the correct image rotated
according to the Exif data from the camera.
3. Observe that the photo in the Project Bin also shows the correct image
rotation according to the Exif data.
4. Observe that playing back the image in the timeline shows the image
correctly oriented in the playback preview window.
5. Render the project to an MP4, and observe that the resulting video shows the
image in the original non-Exif rotation.
OBSERVED RESULT
The resulting video shows the image in the original non-Exif rotation, not as
it appeared in the Project Bin or Timeline.
EXPECTED RESULT
The rendered video should have taken into account the Exif data of the source
image when rendering.
