upscale to 4k? any benifit?

[Shadow_Storm56]

Simple question, if my video is taken in 1080 is there any quality benifit in rendering it up to 4k in premiere or is it just a waste of time and space?

the only case where upscaling makes sense is for example if you'd put it on youtube, because that way you get more bitrate for what is essentially still 1080p video.

 

if you're only gonna use it locally, you can have whatever bitrate you want, so essentially yes, its a waste.

It is for youtube.

Upscaling to 4k from 1080p is most likely going to hurt the quality as it has to calculate a lot more pixels. Personally i think upscaling 1440p is the best option as YouTube will automatically encode the video using the vp9 codec instead of the standard h264. |
 

Also the type of upscale method is important as some will soften the image in the process whereas others will retain the sharpness

 

What software are you going to use to upscale?

Actually it is not a good idea since 4k is exactly 4 times the since of 1080p, which can be scaled losslessly.

1440p is 1.78 times the size of 1080p and scaling to that resolution will reduce the quality.

The answer is yes if Uploaded to YouTube as others have said, but only because of the higher bitrate.

What if I just render it to have a higher bit rate?

Won't change anything as long as the bitrate is high enough in the first place.

Youtube will still butcher it.

Youtube has set bitrates for their specific resolutions and no matter whether you upload 40mbps or 100mbps at 1080p it will be reencoded to something like 6mbps.

Higher is better for "sampling" the reencode with more details.

But 4k would be better as youtube will invest more bitrate to the reencode.

I always upscale any 1080p Video before uploading it to Youtube. The Youtube 4K Preset in Premiere will do just fine in most cases.

that video makes a few good points, but it doesn't cover everything.  such as there's no benefit of scaling up to 4K if the original 1080p video's quality is horrible.

Source material as 1080p, upscale to 4K only if it's for youtube or your TV upscaler is horrible and you wish to show videos to your friends. Just finished comparing 1080p vs upscaled 4K on youtube, if still wondering what the difference may be:

Is it just me or does the 4K video look like it has less dynamic range here? I can see the sky blowing out and the blacks clipping visibly when he switches tabs...

I assume youre talking about that clip on a boat? I see it other way around. Sky is overexposed on purpose. 1080p version flattens the colours and makes them more washed out. I've linked test clips under description if you wanna compare on your own, as this was recorded with OBS that plays a small part how it looks on final video.
