Which model is best to upscale 480 old TV to 1080p?

General Discussion

I’ve been using VE 2.6.4 since I bought a few years back, and really like the ‘Dione Interlaced robust dehalo’ model.

I’ve downloaded a trial version of TVAI 5.4, but can’t seem to find that model in the models that are available.

Does anyone know where it is, or has it been removed from 5.4?
If it has been removed, what is the most current version that still has it?

Also, the 5.4 doesn’t seem to offer a CRF slider bar. Has that been replaced with the ‘low’, ‘medium’, and ‘high’ settings?

I use my 2.6.4(and any upgraded version) to upscale old TV 480p shows and movies…anyone have any suggestions as which ‘model’ is best?

When I used the Dione model, it took about 2.5 hrs, to upscale a 1 hr(42mins) 480 video to 1080p, and ‘about’ doubled the original file size(1GB to 2GB).

When I experimented with Proteus, Artemis, and Theia, they all took the same 2.5 hrs, but created 11GB files—and they didn’t look any better than the Dione one using my old 2.6.4.

Suggestions?

Thanks!

In the Preferences you can still activate the old models. I would give it a try with Iris medium quality at first.

Thanks for that info…I found the old models in the preferences section.

Tried upscaling the same test video as used for the above tests, using the Dione Interlaced robust dehalo’ model- it took the same 2.5 hours, but produced a 14GB file that did didn’t look any better than my original test using the old 2.6.4 Dione model(2GB) or the 3 tests using 5.4 Proteus, Artemis, and Theia models(11GB each).

So, unless I’m missing something somewhere(hidden/unknown settings), I’ll just stick with my old 2.6.4 using the Dione model.

on the right look for Adjustments and Codec Settings to adjust the encoding quality!

I’ve been using the ‘High’ setting, mkv. Would the file size be smaller if I used the mp4 container?

The container should not matter. Just switch from high to medium quality dynamic to get the file size down. I personally encode via H265 Main 10 with Dynamic Medium setting. :slight_smile:

Bit late to the discussion, my go-to for these is Iris MQ (aka Iris2) with Auto parameters, which works well for VHS-ish and somewhat better stuff I find. I usually upscale to 1920x1080 Letterboxed.

There was also a good tutorial from way back in the day for using Dione, which was intended for interlaced data, with progressive data and it works decently too. Iris2 is still my go-to though…

this is the workflow I used at the time when I wrote this guide.
