SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** Here's a video that shows my issue I'll explain below: https://www.youtube.com/watch?v=18wVcRhxOsc When dragging a section of a clip from the clip preview into my timeline, a different part of the clip is added. In the example video above, I drag in the section of my source clip starting at around 3:32, but then the section of the clip around 7:20 appears in the timeline. Same thing happens for other clips in my project, but not all of them, despite all of them being recorded the same way (mkv files from OBS). I checked under Edit Duration, and the Start Crop for the clip is 00:03:32:40, which checks out. STEPS TO REPRODUCE 1. Start a new project, add the clip (attempted to attach but it's 500+ MB) to the clip library 2. Open the clip in the Clip Monitor, then select an in and out point somewhere in the middle of the video 3. Drag the clip into the timeline OBSERVED RESULT A different section of the clip is added to the timeline EXPECTED RESULT The selected section of the clip should be in the timeline SOFTWARE/OS VERSIONS Windows: 21H2, build 19044.2846 macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Version 5.105.0 Qt Version: Version 5.15.9 (built against 5.15.9) ADDITIONAL INFORMATION - Tried on latest stable (23.04.0), as well as the latest build at the time of me finding this (23.07.70 (rev. 312e16117)), same results - Tried with and without the proxy clip, as well as deleting and recreating the proxy clip, same thing happens - The issue is consistently reproducible if I start a blank project, import that clip, and drag a section into the timeline. However, if we start by dragging in the entire clip, it looks fine in the preview and preview render, but then after shrinking the clip from the sides to the part I want, it moves to the wrong section of the clip again. - I did a preview render around that part after dragging the clip in the timeline, still see the wrong part of the footage, and despite the render seeming fine otherwise it says "Preview Rendering Crashed" at the bottom of the window with the following info: [h264 @ 000001c5083db040] co located POCs unavailable [h264 @ 000001c5083db040] co located POCs unavailable [h264 @ 000001c508688040] co located POCs unavailable [h264 @ 000001c508688040] co located POCs unavailable [h264 @ 000001c508df19c0] co located POCs unavailable [h264 @ 000001c508df19c0] co located POCs unavailable [h264 @ 000001c50868fe00] co located POCs unavailable [h264 @ 000001c50868fe00] co located POCs unavailable [h264 @ 000001c508690600] co located POCs unavailable [h264 @ 000001c508690600] co located POCs unavailable [h264 @ 000001c508893280] co located POCs unavailable [h264 @ 000001c508893280] co located POCs unavailable [h264 @ 000001c508891680] co located POCs unavailable [h264 @ 000001c508891680] co located POCs unavailable [h264 @ 000001c508892a80] co located POCs unavailable [h264 @ 000001c508892a80] co located POCs unavailable [h264 @ 000001c508890e80] co located POCs unavailable [h264 @ 000001c508890e80] co located POCs unavailable [h264 @ 000001c509737400] co located POCs unavailable [h264 @ 000001c509737400] co located POCs unavailable [h264 @ 000001c509731800] co located POCs unavailable [h264 @ 000001c509731800] co located POCs unavailable [h264 @ 000001c509732800] co located POCs unavailable [h264 @ 000001c509732800] co located POCs unavailable [h264 @ 000001c509738800] co located POCs unavailable [h264 @ 000001c509738800] co located POCs unavailable [h264 @ 000001c509734800] co located POCs unavailable [h264 @ 000001c509734800] co located POCs unavailable [h264 @ 000001c509b5a5c0] co located POCs unavailable [h264 @ 000001c509b5a5c0] co located POCs unavailable + + + RENDERING FINISHED + + +
Thanks for your report. This migth be an issue with the encoding of your files. Can you please try the following: In the clip monitor, select the full clip, from first frame to the last (using I and O). Then right click on the Clip Monitor, and in the context menu, select "Extract Zone". This will make a lossless transcoding of your clip and add it to the Project Bin. Now check if the same problem happens with this converted clip. If not, then this is an issue with your clips format and we will need a sample to understand the issue.
Hi, thanks for taking a look! It seems that the problem is with the encoding of my files as you said. I tried the steps you listed and with the transcoded file I can't reproduce the issue. The original clip I showed in that video is too large to upload, but I have a different clip recorded on the same day that I'm seeing the same problem with, so I will attach that to help us understand the issue. Thanks again for your assistance!
Actually, *that* file is also too large to attach directly, so I've uploaded it to google drive here: https://drive.google.com/file/d/1yTn0SMiLDQY7fzva1-nDXEMjjmbKxClH/view?usp=share_link
