upscaling 480p to 1080p - an impossible task ?

I have footage 720x480 that I am trying to upscale to 1920x1080.

This is obviously a huge leap, perahps too huge to be feasible. Yes, 480p to 720p might be OK but 1980p, probably not.


Do you guys know of anything that might do this for me?

I tried Compressor, and am trying Red Giant Instant 4K, both not giving great results.


I have seen footage which was originally 480p to 1080p look great, but I think they went through it frame by frame or something like that.

Any comments ?



ps: what about Photoshop?

You're correct that 720 might be more realistic. A lot will depend on the quality of the SD material.


In Compressor, mark a short, but representative section and test the effect of different adjustments in the Quality section of the Inspector.


I don't have the Red Giant product, s I can't comment.


If it's a very important project, consider outso the upscaling to someone who has converter hardware.


Good luck,

Thanks Russ...

Upscaling hardware... hmm, I'll look into that.

Any comments on the new Photoshop preserve detail in upscaling enhancements?

I know of an organization who did SD to HD like this but I think they went through it frame by frame. I don't know what software or process they used but it looks amazing.

All I know was it was a long, long process.


@IanRBrown -- I am not looking to improve the quality of the original SD but I am looking to maintain as much quality as possible as I am going to mix this SD footage with existing footage which is natively HD.

Black Magic Teranex is a hardware solution, you would play our SD source files through it and it will uprez them to HD.

The Teranex is in use world wide, you may be able to locate a production facility near you that can do the conversion for you.

Do a short test sample first - like all conversion processing, the higher quality source files you have will give you better results.


Depending on the length of the file that you are trying to uprez, using the better upscaling in the latest versions of Photoshop may be worth a try.

Output an image sequence, set an action in Photoshop to upscale the image size, run the action on the individual frames, and then reimport the upscaled images as an image sequence.


This may become cumbersome if you have a lot of footage to upscale.

We do this regularly with our archival footage from ye olde 3/4" and Betacam days. We just drop it straight into a timeline and let FCPX do the scaling. the biggest headache is filling the pillars.

All upscaling is a compromise. You can throw money at it and buy specialized hardware or well-researched software. You've got to figure out the relative values of your alternatives.


We thought it was SUPER important to have SUPERB upscaling. Didn't turn out to be the case. No one in the production workflow really cared much once we looked at the various options.

We go to 1080 regularly.

Your tolerance for pixelation will determine how much money you must throw at this project.

The math is not difficult:

a. 720x480 = about 340,000 pixels

b. 1920x1080 = about 2,100,000 pixels


b/a = about 6 so every pixel is being blown up about 6 times to fill the entire space. Which isn't accurate at all since the HD frame is only 2.25X taller than SD and there are the Pillars of Blackness that don't really count.


Besides, we usually don't fill all the way to the top and bottom, preferring to allow future video geeks to do their own cropping. It all gets pretty crunchy without external processing of some kind, for sure. It's all about the $ and our people, who have the money, said, "Eh."
