Quick blog post about an awesome (free) video upscaling tool I use by the terrific @finnvoorhees https://christianselig.com/2025/06/awesome-upscaling-tool/
A slept on upscaling tool for macOS

I upload YouTube videos from time to time, and a fun comment I often get is “Whoa, this is 8K!”. Even better, I’ve had comments from the like, seven people with 8K TVs that the video looks awesome on their TV. And you guessed it, I don’t record my videos in 8K! I record them in 4K and upscale them to 8K after the fact.

@christianselig Awesome! I was wondering how you managed 8k

@christianselig @finnvoorhees I will have to try this with some TED Talks 🙂

@christianselig @finnvoorhees Thanks, been looking for something like this!

@christianselig thanks a lot for the info. I’d been looking for something along these lines.

Did you mean ‘extensive’?
“this library is an extensive of Apple’s Metal graphics library”

@christianselig now that you have a PC with nvidia card, you have much better options for upscaling. Lmk if you want me to point to some good online communities.
Show threadChristian SeligJun 30, 2025
@covercash I've tried a bunch of them, but never had the same performance:speed ratio as Apple's MetalFX. Topaz is admittedly a fair bit better if you're willing to put in the time

@christianselig aren’t you looking for a 5090…
Show threadChristian SeligJun 30, 2025
@covercash Yeah, that’ll even the playing ground a bit more but it’s still “only” about 5x faster than my 3060 Ti for AI work, it’ll bring it from over a day to around 8 hours which is still a fair commitment versus an hour. Enough that it’ll make it worth it though no doubt

@covercash @christianselig Absolutely not my experience.

@christianselig @finnvoorhees the S1ii is a wonderful camera. Have the S1Rii since I shoot more photos but bodies and software are mostly the same. Joy to use
Show threadChristian SeligJun 30, 2025
@janwedek That’s awesome to hear, and congrats on the beautiful camera. My only wish with the S1ii that it had the OLPF from the S1H but it looks incredible otherwise
Show threadJan WedekindJun 30, 2025
@christianselig I saw some complaints about this on the usual forums. Seems pretty certain that a S1Hii will come sooner or later too and might have it again. My guess would be a stacked sensor too, like Z8/Z9.
Show threadChristian SeligJun 30, 2025
@janwedek then I worry that it’s gonna be like $5K haha

@christianselig @finnvoorhees Thanks, looking forward to trying it on old VHS videos.
Show threadChristian SeligJun 30, 2025
@PenguinToot I’d be curious how well it works on that, I can’t imagine their internal model was trained on content of that style. Topaz has a Starlight model that was however and is pretty remarkable in some cases
Show threadPenguinJun 30, 2025
@christianselig @finnvoorhees I’m sure it wasn’t and I don’t have much hope. Someday my 1980’s VHS-C home videos will be upscaled but my children will have to do it (I’ve tried Topaz with poor results). Thankfully I have later ones in Hi8, the best SD format with great color that makes up for the low resolution. And fortunately HDV & AVCHD for high school videos 🙂
Show threadChristian SeligJun 30, 2025
@PenguinToot nice yeah I was fortunate that most of mine were in Hi8 too

“tool”?

Awesome video. I haven’t built a PC in probably decades. Weird how both nothing and everything has changed 😆

Show threadChristian SeligJul 2, 2025
@ccunning It's a lot easier now I would imagine! And good catch on that typo, changed!
Show thread CalebJul 2, 2025
@christianselig I dunno. My first build used an AMD K6-III which used the same socket and motherboards as Intel chips 😱
Show threadChristian SeligJul 2, 2025
@ccunning Wow, that would help! I almost just assumed pre 2010 everyone was just soldering things manually :p
