Can someone suggest a video editor that works in affordable laptop. I downloaded Flowblade. It starts okay. But as soon as I add a video, the application closes.
It's very difficult to run a full feature video editor on such a low power laptop.
Still, I would suggest you may try 'kdenlive' which more stable than flowblade.
Editing may not be a huge problem but previewing and final rendering needs more computing and RAM.
If you're looking for just slicing/cropping and similar lightweight tasks then you may try 'ffmpeg' command-line tool as well.
