I think I fixed the issue. Would be great if you could install the fixed version available here: https://origin.cdn.kde.org/ci-builds/multimedia/kdenlive/release-25.08/windows/ Install it and try opening the crashing project. Can you confirm it works ? Does everything seem to be in place, no missing effect ? Thanks in advance
Thanks for this, the file opens! A comparison of the previous rendered output and a render with this version shows hints of differences, likely compression artifacts or noise. From that check everything seems to be in order. Thanks again for looking into this, and getting a version with a fix so quickly!
The comparison took this form: ffmpeg -i mostRecentRender.mp4 -i freshRenderNewKdenlive.mp4 -filter_complex "blend=all_mode=difference128" output_diff.mp4
What's interesting is that this new build of kdenlive is able to open the shared save file, save it, and the latest release can open that no problem. steps * download new build * open shared save that crashes * save * launch public release * open the file that was just saved * see no crash And I appreciate this, because the build linked here is super slow to interact with. Not sure if it was something I did in unpacking and launching or what.
