In the render dialog -> disable "parallel processing" and try again. (In reply to emohr from comment #1) > In the render dialog -> disable "parallel processing" and try again. Just tried this, but had no luck :( Found a MLT bug that seems related: https://github.com/mltframework/mlt/issues/657 Looks like there have been recent changes to MLT to better support this. Can you try setting mlt_image_format based on that Github issue or look at the options used in the "Video with Alpha" and "Lossless/HQ" presets? Hi and thank you for your patience. Your bug report was for a version of Kdenlive that is at least four years old. Can you please check whether this issue still exists in the latest version 24.12.0? If yes, please update this report to reflect the new version and set the status to CONFIRMED. If it works now like you expect it would, you may change the status of this report to RESOLVED - FIXED. At any rate, this report will be closed if there is no activity for the next 30 days. 🐛🧹 ⚠️ This bug has been in NEEDSINFO status with no change for at least 15 days.

Created attachment 131945 [details] Input (Left), Output (right) SUMMARY I want to export a video in lossless libx264rgb. I can convert my source video to this format with ffmpeg just fine, like so: ffmpeg -i input.avi -c:v libx264rgb -crf 0 output.mp4 However, if I try to RENDER to this format using kdenlive, the output video has strange colors. Changing the Project's Color Space does not seem to help. STEPS TO REPRODUCE 1. Render->Create New Profile --- Profile Name: Libx264rgb --- Parameters: vcodec=libx264rgb crf=0 --- OK 2. Select "Libx264rgb" and click Render. OBSERVED RESULT Strange colors. White -> Pink Black -> Green EXPECTED RESULT Normal colors.
