Hi,
I am new to Kdenlive, when I add a rmvb file to Kdenlive, a message says:
Your clip does not match current project's profile. No existing profile found to match the clip's properties.
Clip size: 720X404
Fps: 23.976
And I just cut and deleted the unnecessary part from the clip, tried to save or rendering the clip, Kdenlive just closed or crashed.
What is the problem? the format rmvb is not right?
Thanks for your help in advance.

Thanks, yellow.
but why did it crash when I tried to save and export the clip?
Thanks a lot!
