Lag with longer videos

AthosCSosterAthosCSoster Website User Posts: 7

Whenever i put a 720p 60fps video file that is longer than 20 minutes, my Hitfilm slows down heavily, is it because of my cpu (i3-3250), or my ram (8gb)? I want to know where the problem comes from because it's really annoying.

    I can't speak to the specifics of your CPU, though the i3 is on the low end of the compatibility list. Your RAM should be sufficient.

    On a general note, HitFilm works much more smoothly with shorter videos.  If you can split your long piece into smaller ones, that would help.  I recommend clips no longer than maybe 5-6 minutes each.

    Transcoding can also help.  If you don't know what that is, then you're probably not doing it, and I strongly recommend watching this video for more information.

    Long story short: if you transcode your single long clip into several shorter ones, you'll probably have a much smoother editing experience, even with a less-than-ideal CPU.
