video upscale

Postby sjf » Thu Jul 23, 2020 10:21 am

Currently using PRE15 on a Mac, to edit home videos all filmed with VHS or Hi8. These have been digitized and now reside on DVD. Nevertheless, video still blurry, especially bad on larger screens.
1. Is there a valid way to upscale resolution? Is video enhancement the same thing? Who makes legitimate software and/or hardware to do this, and can it be done on a Mac?

2. Unrelated question - have been unable to update to Catalina OS since incompatible with PRE15. Are there other significant benefits to upgrading to PRE20?

There is a process that uses a bunch of AI to sample and upscale the footage. What I do is to play around with the sharpen tool and see if you can get something you are happy with. VHS tapes have low resolution so getting it to look sharp on a 1080p monitor or TV is difficult but....

The video below has information about how it is done. I have not tried this and not sure how involved the process really is

1. Video upscaling is a best done by your TV and disc player, and most do a good job of that. But DVDs are just standard resolution, so there's a limit to how much you can enlarge it before it looks soft. You may be able to upscale your DVD video using a third-party program, but I don't know what that program would be -- and even it wouldn't create true HD from standard resolution. But also note that if you put the video back on a DVD, you'll be downscaling it again, so it will still be standard resolution if you're playing it off a disc.

2. Premiere Elements performance has not improved much since version 15, other than being able to edit H.265 HEVC video. But you can see the list of new features from each version on your product pages. It's those features rather than improved performance that would be the best reason to upgrade. That and Apple's OS upgrades that continually make old software useless.

Here are the new features for version 2018: https://muvipix.com/pe2018.php
Here they are for version 2019: https://muvipix.com/pe2019.php
Here they are for version 2020: https://muvipix.com/pe2020.php

Thanks all for the input. Steve mentions that putting enhanced video back onto DVD would result in downscaling again. Is there another way to do this? Perhaps uploading to a 3rd party site for select folks to stream, or would putting video on USB give better resolution. I have previously tried putting a 4K movie on USB but it did not play smoothly - unsure if that was my TV, which was not 4K, or was the USB too slow - if the latter, what specs for USB are ideal?

I am not sure 4k video plays on a non 4k tv unless you are viewing TV through streaming Youtube. 4k files need to run on USG 3.0 because of the size.

Topaz Labs sells a product called Video Enhance AI specifically designed to enlarge and enhance video. Needs interlaced video to be de-interlaced before upscaling, but the results are impressive. See this link for more information: https://topazlabs.com/video-enhance-ai/

Requirements:

Looks like the software is $200 USD.

System Requirements: 1. Need nVidia GPU >3GB VRAM to run fast (CPU can run but quite slow). 2. Cannot handle “interlaced” video directly, footage needs to be to de-interlaced first. 3. Windows 10 platform, Mac OS 10.13 or higher.
