Where Kdenlive fits
Use it when assembling footage into a sequence with control over tracks and cuts.
Check before you choose
Test a sample from your camera and use proxy media if the original footage strains your machine.
Find the right edition
Start with the destination for your device or the publisher's website. Use the current requirements and terms there to confirm the edition you need.
Compare the workflow
A media player, a timeline editor and a live production tool are not interchangeable. Begin with the format you capture and the output you need, then test a short project on your hardware.
