Appears to be Snow

[rblu]

I have a clip that was shot with the iPhone 11 Pro,1920-1080,24fps.I can see what appears to be snow when viewed,,can anyone tell me what causes this?


Thank you,,

The video appears to be 24 unique frames per second, with repeated frames to give a 60 fps video.

I don't think this is phone footage, this phone shoots 24 fps at 4k only

Clip plays back fine here in Windows Media Player and VLC with no "snow". MediaInfo reports it as having a frame rate of 59.40 and a constant bit rate of 9.004kb/s.
The clip also plays back smoothly in DaVinci Resolve.
I would suspect the media player you are using. Here's a frame grab. As you can see, no snow.

Davexnet you are wrong. Look at the video recording section in that link.

This is what it says: What did I miss? ALso the bitrate is too low

4K video recording at 24 fps, 30 fps or 60 fps
1080p HD video recording at 30 fps or 60 fps
720p HD video recording at 30 fps

Also if you search for sample movies, there is some original footage for download

It also shoots at 60fps in 4k. Either this was actually shot in HD at 60fps, or it's 60fps 4k downscaled to HD which given the detail in the pic is what I suspect..

In either case, it is not as the OP described, hence my question

Thanks guys,,Im a bit of a novice when dealing with video,,I do notice a difference in clarity between iPhone native app and Filmic Pro. I first noticed it when editing in Premier Pro..

Thanks again,,

It does have a significant amount of noise and (over) compression artifacts. Some noise reduction can help.

jagabo,
thank you,,I suppose the noise was due to too high ISO,,as for over compression, please explain and how do I avoid it in the future...

Use more bitrate. Use a better encoder. Use better encoder settings. Use variable bitrate encoding, not constant bitrate.
