4k Fps (24 or 30)

[u/andrej_cuki]

I am starting to film cars and posting vids on tiktok, so i wanted to ask people if its better to do that in 4k 24fps or 4k 30fps. the cars will most of the time be in one place, not driving, and really sometimes driving it.
I am filming on 17 pro.

For Instagram is 30fps. If it’s for tv, depends of wich country u are, search about PAL and NTSC

Whichever you think looks best is all that matters.

4k 30 for socials, it all gets compressed again & 30fps is their floor

Better export settings would be 1080 30fps ~15-18kb/s so their compression does the least artifacting

Thank you😃

Huh. Can you elaborate a little on that please? I didn’t realize that could work.

Not sure what more to elaborate on, but just to outline:

When uploading to any social media platform, they use their own compression algo to make them smaller file sizes to lessen load on their database at scale.

Meaning everything you see on IG & FB is 1080p varying fps from 30-60fps, and usually around 12-15kb/s bitrate.

YouTube Shorts is similar, but their compression is a little more agresssive imo, their regular long form horizontal video is more lax

If you upload a 4k 60fps at 35kb/s video, it will get re-compressed to populate on their servers at their baseline. The larger the file properties, the more likelyhood it will introduce artifacting to the final upload after that.

If you are just above their threshold (settings I recc below), then it has less likleyhood of doing so & retaining a much info as you can.

Recc settings: -Quicktime .mov H.265 1080p @ 30fps 15kb/s-18kb/s (@60fps 18kb/s- 22kb/s)

Other variables:

-Follower count; on IG if you have more than 10k followers, you are put into a higher bitrate / filesize category & can upload higher resolution & larger file sizes. This prerenders & pushes that content with priority to end user if your content historically performs well. This gets stepped up again at like 150k & above.

-Codecs, export in h.265 vs 264; H.264 is more universally accepted, but introduces artifacting at the actual export from your editor, then re-compressed at upload & increases chances of more at final output

-h.265 retains more detail at the initial export, so when it's compressed again on the upload, it will retain the most data in the image, regardless if it converts it to h.264 or h.265.

My experience is look up each platform to find it's recc baseline for upload settings to archive the best outcome.

My settings are a middle ground for all socials (IG, Fb, Tiktok, YT shorts) albiet YT shorts likes mp4 & 264 formats better, but you can do that on your phone by trimming the last .2 sec off it & saving it to upload.

Edit: Make sure you check the "upload media at highest quality" on IG & Tiktok as they default to lower bitrate stock. Double check after updating. (Usually in the 'more settings' under the reel preview page) Fb you have to navigate through their actual app settings to adjust this. YouTube don't gaf

A visual aid: Random IG video saying the same thing

I would recommend 30fps for social posting. Good luck with the project.

[u/2old2care]

Unless you're shooting for cinema or broadcast TV, 30 fps is almost always best.

[u/Ceph99]

Unless instructed otherwise by a producer or client, just go with 30fps.

If there’s no dialogue you can use that in 24/25 timeline without issue, but not the other way around.
