iPhone 11 MOV files pixelated in PP13.1.5 and after export

Hello, I've shot some great mountain running footage on IPhone 11 at 120fps 1080p which looks great on phone and in PC, but not great in preview window and the sky is pixelated in the exported footage. I've sought help from a film/media professor friend of mine via text and she said my export settings looked good. She suggested I try interpreting the footage, rendering, and I reuploaded from my phone to PC and always the same result. Something is happening to cause the quality to degrade or some setting is wrong upon bringing the files into the program. The phone is set to "most comparable" not HVEC. Any ideas what might be happening?

iPhone footage is known for using variable framerates, which PPro has a hard time with. Consider transcoding the footage first with the use of Handbrake to a more edit-friendly codec with a constant framerate.

Hope this helps.

Thanks so much!! What would be the ideal codec?

Just select SuperHQ 1080p and change the settings to your preferred framerate and sound options.

Since you want to do further editing/grading to the footage, I would suggest you try to minize the re-encoding process. Jack up the quality slider to Placebo quality. You may end up with a larger file than your source footage, but at least you're not throwing (much) information away in the process.

Hope this helps.

which format are you exporting to? what are your export settings?

and what are your sequence settings inside premiere pro?

go to your file properties from inside the project panel, do

you see 'variable frame rate detected'? if yes, try to encode

those rushes into a constant frame rate (check which apps do so)

Thanks for your reply

1. I don't see anything that says "variable frame rate" on any of my file properties

I'm attaching pics of

- sequence settings

- export settings

Again just to reiterate, my friend who is a full maker was asking me if it looks good in the playback video and it doesn't. It does seem that I'm getting the same pixelation in the playback window as in the export even when it's set to "full" quality, none of which occur in the original files when I watch them outside of PP. If the files at full quality don't look like they should in the playback window is that a sign the problem exists before export?

I don't know why the pics are uploading sideways. Apologies.

Sequence settings look okay. Do you think you can post an example of the blurryness you're talking about? Btw you can take pics on your PC and upload them directly by hitting Shift+Windows+S

Also if you right click in Premiere on your footage and go to Properties you'll see the Variable Framerate thing. Phone footage is really bad with that. In fact it's just all out bad footage to work with (although it shouldn't be turning out blurry compared to the original--not due to VFR).
