Video editing stutter

[unknownmiscreant]

I am currently trying to edit a fairly short (5-6min) video on the ryzen rig in my signature. However there is severe timeline and playback stutter. I'm using shotcut to edit 4k h.264 mp4 files shot on my oneplus 3. I have the video files on the intel 520 series SSD (not the phone).

 

I understand that 4k files will not be helping matters, but is there any way to improve timeline performance? None of the hardware is being fully utilized. Less than 50% CPU and under 10% GPU load, with 8GB of RAM free. I have tried switching to openGL and enabling GPU acceleration.

 

I'm  thinking about re-encoding the files to a lower resolution, and a different codec. What would you recommend?

 

I understand shotcut is not the best software out there for video editing, but since I only edit videos at max 4 times a year, I do not wish to spend money on sorting this out, although I am willing to switch from shotcut if there is a compelling option for a reasonable price given how much use I will get from it.

How bad is the stuttering, You can always encode the files into a lower resolution and codec, and then using that file to edit and then encode it back to 4k, I know it's a longer solution but sometimes the long way is the better way

Really really bad. Just about unworkable.

 

Yeah I understand I can edit at 1080p, I was hoping for some recommendations for intermediate codecs that require less decoding than h.264.

I don't know many codecs I just choose one that fits within the YouTube thing and that's really odd why it's not being normal

Okay, thanks. Might just be shotcut idiosyncrasies.
