I have an old family film, originally on Super 8 then converted to DVD via
VHS so a mixed start in life.

I wanted to see if it could be enhanced so I downloaded and installed winxvideo-ai.exe. It took 36 hours to enhance it on my Gigabyte Z790
(Intel UHD Graphic 770) and was unplayable.

I then dusted off an ASUS Z170-K PC, eBay purchase with a Specialist PC
BIOS and Nvidia Quadro M4000 graphics card and tried again. Fine, 20
minutes or so and it played OK. Not sure if it's much enhanced. However,
it won't play on the Gigabyte.

I haven't bought an add on Graphic card for 20 years or so, is it possible that the video is so "enhanced" that Intel's built in graphics (or VLC)
just can't handle it?

The degree of enhancement (or otherwise) shouldn't have any implications
for a video file's playability.

It's possible that the software that did the "enhancing" saved the
result in a video format that your PC can't handle (i.e. doesn't have
the right software to handle) ... fairly unusual for VLC not to be able
to handle video, though.

What's the file format? What codec does it use? Have you tried
re-converting it using a different codec or container format?

How up-to-date is your copy of VLC?

Hi Daniel, long time no hear :-)

The original was an mp4 and it churned out a longer mp4, 102K became 1.2 MB.

It used the NVidia card for the rendering.

It runs in VLC on the PC it was rendered on but not in VLC on my main PC.
Both copies of VLC say they are up to date.

I have never played with graphics or video, all the icons I produce for my programs look like stick insects :-)

MP4 is just a container. Different MP4 files can have the video inside
them encoded in different ways.

Not confusing at all, eh?

What happens if you encode the video again without using the nVidia
card? It could be that the card is using a codec that it can decode but
that the other PC doesn't have (I presume it doesn't have the same
nVidia card).

When I did that on my Gigabyte Z790 (most modern and fastest PC) it took
36 hours to produce an unplayable video!

I think I will stick to the original and treat it as "historic" :-)

36 hours to upscale 102 kB of video?!?!

Yes! Don't think upscale is the expression I'd use though :-

I would imagine that most set top satellite TV receivers must be able to
do HDMI upscaling in real time ?

That's nuts! My old (c.10 year) PC would transcode (using Handbrake, shrink files while maintaining most of the quality) in pretty much real time. My newish Mac Mini does it at 1000ish fps - 1/40th of the time. So a 2 hour film 5GB to 1GB in about 3 minutes.

Progress, I suppose . . .
