Which Video Software Editing Tool For 4k Rendering ?

[Sector]

hi!

i have taken some 4k videos with my gopro and i want to edit the video do you have any suggestions which software i can use ?

i have a licensed camtasia software but the video is not running fluently and i think camtasia does not support 4k rendering ?

i want to also add a "speed" effect that plays my videos faster.

any software suggestions please ? free , tirial or fullverison .

thank you

Did you try GoPro Studio, Go Pro's own software.

Realistically, this is more likely to be a hardware issue than a software issue. What is your video card? What kind of drives are you trying to play from? How long are your clips? Untranscoded GoPro is known to be quite belligerent on playback even in HD.
