Bug ID: 445675
Summary: Rendering widescreen 16:9 format to DVD always adds
black bars
Product: kdenlive
Version: 21.08.3
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Video Display & Export
Assignee: j...@kdenlive.org
Reporter: norb...@preining.info
Target Milestone: ---
SUMMARY
It is not possible to render to widescreen DVD (NTSC) without adding black bars
at top bottom, despite input data is 16:9. All renderings to DVD (VOB) result
in 4:3 rendered video with black bars, which, when shown on a normal modern TV,
results in wrong aspect ratio.
STEPS TO REPRODUCE
1. create a project in some 16:9 format
2. render to SD/DVD
OBSERVED RESULT
output contains black bars at top bottom
EXPECTED RESULT
correctly encoded video that shows full screen (filling the full screen) of a
16:9 TV
SOFTWARE/OS VERSIONS
Operating System: Debian GNU/Linux
KDE Plasma Version: 5.23.3
KDE Frameworks Version: 5.88.0
Qt Version: 5.15.2
ADDITIONAL INFORMATION
Changing the Project format to NTSC widescreen does not help, rendering to DVD
again creates black bars.
Changing the project to DVD, black bars are already added in the preview.
What I currently do is:
* render to 16:9 mp4 high quality
* use videotrans' movie-to-dvd with the respective options -m ntsc -q high -a
16:9 -M
* use dvdauthor to create the dvd structure using the previously created vob
file
* burn
