IMPORTED FOOTAGE TURNS LAGGY GREEN

the first frame of the video is good, after that its just laggy green, like in the screesht, near the end there is like 2 frames also showing good image. This is a iphone x 4k video however its very weird as im making a video with the camera and all imported files are perfect, this video of a led strip and it just doesnt work, i tried re filming it and its literaly the same thing. I tried importing a video of just my room in general and it works??  Maybe there is too much pixels or something i have no clue haha

It's more likely your camera issue with capturing such imagery. Have you tried viewing the footage with another software?

That can also be decoding errors from H.264 and H.265 footage. It just takes a little glitch in the data to foul things up. That is just one of about a hundred good reasons to never use compressed footage for anything but delivering a product to a consumer.

Look, do yourself a favor and get one of the apps that make phones work more like proper video cameras. 

Built-in phone camera apps suck.  They shoot at variable frame rates.  They record in crummy codecs. 

You aren't doing yourself any favors by just picking up the phone and rolling.

Same problem... switchin codec, frame rate and cameras doesnt solve that issue for me...

Your issue sounds like its related to your GPU.

1) Which GPU are you using?

2) Ensure you have the latest GPU drivers installed

3) Take a screen grab of your Composition Panel (DO NOT CROP THIS IMAGE!)

4) Take a screen grab of Project Settings (just the Video Rendering and Effects tab/section)

5) Take a screen grab of Preferences>Previews AND Preferences>Display

In Project Settings (Ctrl + Alt + Shift + K) > Video Rendering and Effects i switched to Mercury Software only and it worked. Looks like my Intel GPU was kinda broken. Thank you for your help!!!

Transcode with HandBrake your HEVC video (iPhone H.265) to a more compatible H.264 format and with this you solve your issue.

I would never transcode any footage to h.264. You are asking for compression and color artifacts. If you need to transcode footage do some research into visually lossless production formats. There are several. MPEG interframe is never a good choice for a digital intermediate. Sure, you can get away with it sometimes, but it's not a good idea.

[Byron Cortez]

Of course I would not either, as long as my video was originally recorded with Apple ProRes, DNxHR / DNxHD, etc., in that case it would be losing a lot of quality. But in this case it has been recorded with a cell phone what tells me that whatever has been recorded has a level of compression with artifacts and there will be little difference between the one and the other. In any case, it is a valid option to transcode it to MP4 / H.264, the issue is making tests and checking whether it works or not.
