My video looks fine after uploading it to youtube, but not on VLC

[videofan70]

I took the videos with a Galaxy Note 20 Ultra 5G smartphone, and then transferred them to my PC using Feem. After I uploaded it looked fine on youtube

Good quality video https://www.youtube.com/watch?v=JYKF3ETQs2E

But, bad quality when viewing in it VLC before I uploaded it, here..........

almost doesn't even move framewise, though the audio is fine.

Those are NOT public youtube links.

[videofan70]

Yes,they are unlisted, but I gave you the direct URL's you should be able to watch them, shouldn't you?

Post the youtube link for the video. This is the result of the studio link:

done, edited with the right links

The second link looks like a screen capture. What did you do exactly?

Yes, like I was saying (well it's in the video description), I had to do a screen capture to show you what the bad one looks like, because youtube fixed the bad one when I uploaded it to them. I used OBS and took out a segment/part of it with premier pro, but the full version looks bad too, so I know it wasn't premier pro that made it look that way.

You have a video that looks good on youtube but plays incorrectly in VLC?
Upload the real video here for examination...

[videofan70]

Says the max file size for an MP4 to upload as an attachment is 500MB, but I'm having trouble that it doesn't even start uploading it to here. At least I see no progress bar moving

edit- nevermind it worked.

Is your PC fast enough to play 4k video smoothly? Thats quite a high bitrate, too
I don't see anything wrong with the video.

Re-encoded to a smaller size:

There's nothing wrong with the file. I had no problems playing it here with VLC (i9 9900, RTX 4060). I suspect your computer (Core Duo CPU T8300) just doesn't have the power to play it.

[videofan70]

Then why does it play fine on youtube, what did it do to it to fix it when I uploaded it. My computer had like 48 gigs of ram. If it's that what hardware is lacking? Just the CPU. I had to use a high bitrate because the lowest one wasn't recording it at all on my phone. Though I could try some in-between.

[davexnet]

Nothing inherently wrong with video, just needs a strong CPU and/or a GPU to play it properly.
Youtube reencodes the video to a much lower bitrate

Youtube reencoded with a lower bitrate and probably otherwise easier to decode settings.

Not the laptop in your profile then?

Nope, I really need to update that. THIS is my system now. It is old, 12 years old, but I've managed to keep it running all that time, needed to update to windows 10, gonna stretch it as far as I can.

Here's my dxdiagfile

GTX 670 doesn't support H.265 decoding, so no assist from the GPU unfortunately

The discrepancy in video quality between YouTube and VLC likely stems from a playback issue on VLC rather than the video file itself. VLC might be struggling with hardware acceleration or codec compatibility, leading to choppy playback. Try updating VLC to the latest version or adjusting its video settings, such as disabling hardware acceleration or changing the output module. Additionally, ensure your PC meets the video file’s resolution and frame rate requirements. If the video plays smoothly in other players or after upload, it suggests the issue is specific to VLC’s playback settings rather than the video file’s quality.
