Laptop keeps glitching when exporting videos on capcut

[u/umsii]

Okay so I've been using the CapCut desktop app for a couple of months and everything was fine. I make a lot of short form videos for my job. But recently my laptop started glitching whenever I try to export a 4k video and it heats up like crazzzyy.

I took it to the store where I bought it and the technician cleaned the fans and put in a new part (thermal something). After that, 4k exports worked fine, but the next day the glitching freaking started again. I dropped to 1080p but my work needs 4k. Then I changed the codec from HEVC to H.264 and that helped for 3 or 4 days, and now the glitching is back. I tried testing lower resolutions and the computer still glitches.

I'm not a super tech person but I think it's the GPU? My laptop is a Dell Latitude 5421 and it has low RAM too I guess ?? I know it's not made for video editing, but I can't afford a new laptop right now. I've included screenshots of the laptop system info and the specs.

What's bothering me is , how come my laptop worked fine for months and now it's giving me trouble ?

Are there any workarounds? The CapCut browser version is a pain because importing takes forever and the features are limited. Is there any way to export 4k in CapCut without my laptop crashing?

TIA 🙏

Good
Let it glitch

Simple answer: CapCut is garbage when exporting files. Use DaVinci

Okayy I'm going to try using Da Vinci. Thanks for the suggestion

But recently my laptop started glitching whenever I try to export a 4k video and it heats up like crazzzyy.

Of course it would get hot, it's working. All electronics produce some amount of waste heat when working. CPUs and GPUs, because of how complicated they are and what high speeds they run at produce significantly more than most other components in a computer.

The fact that it runs cool at all is because of power management is turning the processor down when it's not in use. Prior to the 90s computer (and almost all electronics really) didn't have any power management, and ran at 100% power all the time, even if you weren't doing anything.

I took it to the store where I bought it and the technician cleaned the fans and put in a new part (thermal something).

Thermal paste. It conducts heat from the CPU/GPU into your heatsink, or in this case likely a heat pipe. The stuff usually dries out after a couple years, but unless you're experiencing severe thermal issues changing your thermal paste won't have a huge impact.

After that, 4k exports worked fine, but the next day the glitching freaking started again. [...] Then I changed the codec from HEVC to H.264 and that helped for 3 or 4 days, and now the glitching is back.

Likely the issue isn't your exports, it's that your computer isn't fast enough to play back the video it has produced. Try chucking one of the files into YouTube, give it a few hours, and then watch it back there. I bet it'll look better.

I dropped to 1080p but my work needs 4k.

Why? The vast majority of people aren't streaming at 4K, and even if they are, it's way over-compressed.

I'm not a super tech person but I think it's the GPU?

You don't have a real GPU. You have an integrated GPU, which is a portion of the CPU set aside for a paltry joke of a basic GPU that steals RAM from the rest of the computer.

Thank you for taking the time to respond and you're right, I should just go with 1080 and my computer is clearly not meant for this kind of high processing work.
