Bug ID: 486430
Summary: Freeze in video render after using Razor Tool and
Removing Space with MPEG-TS source files
Classification: Applications
Product: kdenlive
Version: 24.02.2
Platform: Microsoft Windows
OS: Microsoft Windows
Status: REPORTED
Severity: normal
Priority: NOR
Component: Video Display & Export
Assignee: j...@kdenlive.org
Reporter: pragm...@gmail.com
Target Milestone: ---
SUMMARY
When I use the Razor Tool to add cuts to remove scenes and then Remove Space to
remove the holes in the timeline, the rendered (Project -> Render) video has
freeze frames lasting two seconds or so after each cut. This issue seems to
only present itself when I use MPEG-TS video files as the source. It does not
occur with MPEG-4 sources.
STEPS TO REPRODUCE
1. Add MPEG-TS source video to timeline
2. Use Razor Tool to add two cuts and then delete the scene between the cuts
3. Use Remove Space to remove the hole in the timeline
OBSERVED RESULT
In both timeline and final render, there is a 2 second or so freeze frame in
the video immediately after the cuts.
EXPECTED RESULT
The final render should smoothly and fluidly play across cuts without any
freeze frames.
SOFTWARE/OS VERSIONS
Windows: Windows 10 22H2 (19045.4291)
macOS:
Linux/KDE Plasma:
(available in About System)
KDE Plasma Version:
KDE Frameworks Version: 6.0.0
Qt Version: 6.6.2
ADDITIONAL INFORMATION
Using the OpenShot video editor with MPEG-TS sources, there is no freeze frame
after cut scenes. I much prefer kdenlive's interface. Hopefully there is a
solution that does not involve transcoding MPEG-TS to MPEG-4 for editing. If
there is no obvious solution, perhaps the GNU licensed opensource OpenShot
MPEG-TS library could be of use here?
