SUMMARY I cannot render any projects as webp. It always crashes. STEPS TO REPRODUCE 1. Select 'webp' preset. 2. Press "Render to File". OBSERVED RESULT Rendering of C:/Users/owner/Videos/untitled_%05d.webp crashed [consumer avformat] video codec libwebp unrecognised - ignoring EXPECTED RESULT Output rendered webp file. SOFTWARE/OS VERSIONS Windows: 10 Kdenlive: 23.08.1 ADDITIONAL INFORMATION I looked up the error, "video codec libwebp unrecognised" and found the following, https://stackoverflow.com/questions/67904563/unknown-encoder-libwebp So, I figured it was probably an ffmpeg issue. I downloaded the Windows version from the link and pointed FFmpeg, FFplay, and FFprobe to those but I got the same error so I changed back to the ones installed with kdenlive.
I see only WebM as rendering presets. Where do you get the WebP preset? Maybe a screenshot will help.
I have the same issue. I had this issue in an earlier version (v22.whatever), so i upgraded to the latest version. After installing mediainfo which i didn't knew was missing, Config wizard says "Codecs have been updated, everything seems fine.". But when i render to this image sequence, it crashes. And upon crash, it drops a log file with as contents: Started render process: C:/Program Files/kdenlive/bin/melt.exe -progress C:/Users/USER/AppData/Local/Temp/kdenlive-aaafxd-1.mlt [consumer avformat] video codec libwebp unrecognised - ignoringRendering of C:/Users/USER/Desktop/ORIGINAL_FILENAME_%05d.webp aborted, resulting video will probably be corrupted. I have some images.

Thank you for reporting. I can confirm the render crash. Even with only 1 color clip. It seems that WEBP is not proper set-up.
I was able to get webm to work. webp is a picture format to my understanding. So, maybe that's the problem?

The problem is that you are trying to render in webp but FFmpeg is not compiled with webp support. Kdenlive did not correctly check for missing codecs in this case, this is now fixed with my last commit - the webp profile now appears disabled in the render dialog. I will try to update our packaging pipeline to include webp support in FFmpeg.
