Footage "corrupts", as soon as I put it into the timeline

Hey,
Lately I have the problem that any video files that are normal when I open them outside of Davinci Resolve 17, but when I put them into the timeline it's just looping a couple of the frames, no matter which part of the video I scroll to.

A video of my problem can be found here:

If anyone knows what the reason for that is, please let me know asap
Thanks in advance, Oke

What is the file, codec, resolution and frame rate?
what is the timeline resolution, and frame rate?

Here is some information I got from MediaInfo about the footage:

And the timeline resolution and framerate is 1920x1080 at 24fps

What happens if you set the timeline to 30 fps? Your hardware might be challenged to convert on the fly.

That sadly doesn't change anything

looks like a low res 4:2:0 file, which Resolve needs to covert to 444 at your timeline res.
can you post a small sample?

What do you mean? A sample of the footage?
The thing is that this problem also appears when I use different footage or even just images...

What kind of camera made this? A drone camera?

My impression is that this is an H.264/H.265 Long-GOP codec, and those are rough for post. My advice is to transcode this material with a 3rd party utility and bring it back into Resolve as DNxHR SQ (or a 10-bit codec if you prefer) or ProRes 422HQ. Those two will play back a lot better than H.264.

Yes, please post a sample via a cloud service (like DropBox, WeTransfer, etc. ) and post the link here, with a space in the name since you are a newbie.
But if the same happens with any other videos or stills, let's step back and tell us all about your hardware, GPU in particular.

Since it happens with all kinds of footage and stills here are the specs of my Laptop (Honor Magicbook 16):

AMD Ryzen 5 4600H with Radeon Graphics 3.00 GHz
16 GB RAM
Windows 10 64bit

Btw, the footage was recorded with OBS on default settings.

That laptop has no dedicated GPU, at least you don’t mention one. If so, it’s underpowered for DR. Sorry.

OBS is very bad as a recorder, and in some cases it records variable-speed H.264 codecs, which are even worse than regular H.264 files (which as I said are bad for post, in general). You need a fairly hefty GPU with lots of VRAM in order to work well with Resolve.

Stop saying that. OBS is perfectly capable of writing constant frame rate videos. I swear we've been through this before

Capable, yes. Always, if the machine is busy with another demanding task? No.
Much better than Shadowplay, though.

But it's not the reason of the TO's problem.

But if the machine is busy with another demanding task, then any recording program will have problems. So essentially you're saying that it's a machine problem not a OBS problem, right?

I agree, we need one of the files from Linoke

Correct. If I run OBS on another machine and transfer the video by NDI, the recordings are fine.

I don't think that that's the case because DR used to run (slow)on my old and worse Laptop, which also didn't have a dedicated GPU. Also other editing Software runs smoothly, it's just with DR...

Here is an OBS recording of me playing Super Mario Bros, with which the exact same problem appears:

Btw: I tried reinstalling DR and even older versions, but that also didn't change anything.
Thanks for all your help though, I really appreciate that

Your link is protected.

Your link is protected.

Oops, my bad... Should work now

That file is playing back just fine on my timeline, I am also using a Laptop. I wonder if it is your computer that is having problems playing it back? Timeline is set to 30FPS

Yep, confirmed: That file works perfectly at a constant 30 fps (coughs at Marc Wielage) timeline. So that means it's somewhere on your computer Linoke. Sorry.

No problem on a Mac either.

It could well be because of underpowered hardware. Even on super-powerful hardware, I cringe at running H.264 files, and I swear there's steam and gear-grinding noise coming out of the machine when I try it. It's fine with Raw formats, ProRes, DNx, and any other decent formats.
