Vint: Realtime Video Interpolation and CRT Emulation is now Available. What are your feature requests?

[William Sokol Erhard]

Hi, I'm William. I've written for Blur Busters about framegen.

I'm happy to announce that my software, Vint, is now fully released!
The Vint temporal upscaling application supports advanced machine learning based RIFE interpolation, black frame insertion strobing, and CRT emulation based on the work of the Chief Blur Buster and Timothy Lottes.

I would love to get a sense of what the community would like me to focus on in my continued development.

Edit (11/25): Vint now at version 1.2.0 with added Intel CPU & GPU support via OpenVINO. Vint also includes a new secondary TensorRT-rtx accelerator, additional crt emulation control, RTX Video Super Resolution integration, in addition to an array of bugfixes and dependency updates.

Congrats on the release!

Linux support is the only thing I would want out of this, but I understand that Linux desktop in general is a mess to figure out

[William Sokol Erhard]

Thanks RealNC!

You're not alone in wanting Linux support. I would love to run everything there eventually.

With Vint specifically, the client UI should be portable if a bit of a hassle with all the IPCs and window features. I'm a little more concerned about getting the TensorRT acceleration to work on Linux. It should be possible but it looks like it'll be quite a bit of an undertaking.

Congratulations on the release!
I was curious on one thing, what is the lowest persistence value the CRT shader emulation can target?
There isn't a specific mention of this, but my assumption is that it's limited to the native maximum refresh rate.

[William Sokol Erhard]

Thanks kyube!

I hope to write more of a guide and explanation of how the systems work including the CRT emulation.

Yes, software CRT scanout emulation necessarily has a minimum persistence value equal to the minimum persistence of the display. That is to say, the maximum persistence. Technically you can combine software CRT emulation with low persistence display strobing but that would interfere with the CRT emulation itself.

I am continuing to work on Vint and will be adding and refining features. In the current live build of Vint, CRT emulation is set to a 4x multiplier but I am adding some more config options for the next update.

Hey everyone.

I just released a new 1.0.2 update to Steam and itch.io

I added a 'play file' button, added documentation links and some tooltips, and fixed some minor bugs.

Hi William, congrats on the release!

I’ve been keen to somehow get the CRT beam working over signals from external HDMI gaming sources, like say the PS5.

Is there a mechanism by which Vint could allow this to occur with minimal lag? (Which would probably in practice mean, to work over this content without needing a capture card in between?)

Thanks!

[William Sokol Erhard]

Thanks roginthemachine!

So Vint is naturally working in software. Software also allows Vint to be far more flexible, runs on existing systems, and it entirely bypasses the hardware restrictions of PS5 output for example. Vint can run at 480FPS or higher limited only by the system that's running it. That said, latency will necessarily be higher than hardware solutions. An ASIC hardware solution would require mass adoption. An FPGA hardware solution is very expensive, easily $700-800+.

Vint is build primarily for video content. Vint does support UVC sources including some capture cards so it can take in a blu-ray player or anything else. It's capable of relatively low latency, that is to say as low as the 50-100ms range generally.

I think for console gaming or low latency output, the ideal here would be to have beam emulation implemented in display firmware like they do with strobing. I am interested in software solutions on PC for emulators or PC games but that's a little outside of Vint's current focus.

Hi everyone,

I just released my 1.1.0 update with lots of nice quality of life improvements, bug fixes, and configuration options.

It's on sale for the next week, try it out.


This update is launched alongside my new article. https://blurbusters.com/flicker-vs-framegen/

Are WebMs not supported for offline transcoding? The command prompt shows up like it does for other file types, but quickly disappears with an error. Does Vint write any logs for these failed encoding tasks?
