Hello,
Thank you for this wonderful software kdenlive, I love it !
I have a question. I created a new project with 24fps. I would like to import a 30 fps video.
Is it possible to automatically adapt the video's framerate to the project's framerate lossless ? I know my video's duration will change but I don't want to lose data.
Thank you for your answer.

Ones you created a project with a frame rate like 24fps don’t change it anymore. If you add clips with 30fps to that project they get automatically down sampled with the rendering. 24fps is for cinema, 30 or 60fps is for PC and internet.

Thank you for your answer.
The problem is if I add a 30fps video in a 24fps project, kdenlive changes the framerate and drops frames in my video to match the project's framerate.
I would like that kdenlive, change the framerate and extends the duration of the video, but doesn't drops any frames.
Is that possible ? May I need to resample the video before with ffmpeg for example ?
Thank you
