SUMMARY Kdenlive crashes upon attempting to preview a fadein/fadeout when working with a non-standard extra wide resolution. This is not reproducible with a 1920x1080 resolution, nor is it a product of altered screen ratio (16:9 and 10:1 ratios both work fine with 1080p resolution). I made a video showcasing the steps to reproduce: https://www.youtube.com/watch?v=t2menmuNvjE STEPS TO REPRODUCE 1. Proceed to create a new project 2. Add a custom resolution, 1480x148 3. Add some video 4. Add some fadeins/fadeouts 5. Bring the timeline cursor over the fadein/fadeout OBSERVED RESULT Kdenlive crashes EXPECTED RESULT A preview of the fadeout/fadein is shown. SOFTWARE/OS VERSIONS Windows 10; 1909 Kdenlive 20.12.2 standalone
Doing the same steps as you show on the video but on Windows 7. No crash. Please let me know which settings you have under: - Settings -> OpenGL backend. - Settings -> configuration Kdenlive -> playback.
OpenGL backed is: DirectX (AGNLE) Playback settings: - Use GPU processing: off - Audio backend: SDL - Audio driver: automatic - Audio device: default - Preview volume: 100% - Use external display: off - Output device: empty I also tried the same steps on a Windows 7 machine and indeed, no crash. I'll try with a different Windows 10 machine and report back.
Tested this sequence of actions on a Windows 10 machine with gen7.5 Intel iGPU, no crash. Well, I suppose something might be wrong with my machine/installation then.
Please update your graphic card driver on the Win10 machine where the crash happens. I assume it’s an Intel graphic card.
It's a Nvidia GPU. Should've mentioned the hardware configuration: Machine A: Nvidia GTX 1060, driver 452.06, 3840x2160 screen, crash Machine B: Nvidia GTS 450, driver 385.41, 1680x1050 screen, OK Machine C: Intel Cherry Trail iGPU, driver 20.19.15.5144, 1920x1200 screen, OK I'll try to update the drivers and report back.
No luck with driver 461.40 and clean kdenlive installation; still crashes on this machine after this unique sequence of actions.
On the machine with the crash: - Which OpenGL backend do you have (settings -> OpenGL backend)? - Do you have set the playback resolution other then 1:1 (Monitor, bottom left)? - Test: Set the playback to Wasapi/DirectSound/WinMM: which works best? - Any different in Audio from the machine who crashes to the other machine? - Is the audio driver up-to-date?
