Video Enhancer-VirtualDub like program-to enhance video-when upsizing!

[jagabo]

But I can understand one reason: Is among the few things out there, that proves easily that avisynth is not the Holly Grail. And that probably piss off it's fans.

The fact that some other program has a feature that AviSynth doesn't deminish AviSynth at all. There's no reason someone couldn't write a super resolution filter for AviSynth. I might even be willing to buy a native AviSynth super resolution filter from Infognition if it supported RGB, YUY2, and YV12 colorspaces, was reasonably priced, and didn't have oppressive DRM.

I have no problem seeing and admitting that Infognition's super resolution technique is better than anything I've seen with AviSynth. When watching motion video their upscaling results in less buzzing edges (temporal/spacial aliasing) than simple frame upscaling and sharpening of individual frames. Of course, it's still not perfect, and it doesn't create HD video from SD video. It simply enlarges the frame while producing a sharper picture with less artifacting than most other programs. That's all one expects an upscaler to do.

If I have a DVD quality movie and converting it to digital to store on my media center, is there any value in upscaling it with tools like Video Enhancer to get closer to BlueRay size? Assume will be on a 50 inch plasma if that matters. Was thinking upscaling like 1.5x so it's not double. So if it's 720x480 would upscale to 1080x720.

Thoughts?

Thanks.

No. Leave it as-is. Copy, don't convert, your DVD files into either mkv or plain mpeg. Your TV and/or player have real-time up-scaling which are probably superior and certainly less hassle.

nnedi3 in AviSynth can do better upscaling than your TV. But you'll need to use a higher bitrate.

I see people on this forum making these kind of statements all the time.

I am sure they can back it up with objective tests and references?

So let's address this issue: what special scaling is used in a DVD player or TV that apparently cannot be implemented in software on a computer?

Assuming the software is "just as good," why waste the time?

This may be a stupid question, however is it safe to assume upscaling will always be available on hardware devices or possible at some point you will just end up with a little picture in the middle of the screen? I know today even 4k displays have to upscale 1080p but is there a point when they won't do this upscaling or it will be considered more legacy so the circuitry upscaling SD or lower resolution content will become inferior?

Thanks.

As long as multiple frame sizes are available upscaling and downscaling will be available.

OK I'm torn.

As usual getting two different types of opinions. For and against. Makes the world confusing and fun. If I was to upscale is nnedi3 better than Infognition's Video Enhancer?

No really.

If you have a compressed video I'd say don't mess with it because any transcode will only make things worse. It's like taking a photocopy from a photocopy the latter is always worse fidelity wise. Unless you have to process the video and fix problems with it I'd say leave it alone.

I don't know. I've never used Video Enhancer. All I've done is look at the examples at their web site. In those examples VE looks better than needi3. But I suspect they cherry picked the shots where VE worked well, and didn't spend much time optimizing their AviSynth scripts.

Hi,

I would suggest posting your question at the official video enhancer forum here.

Guess I got my answer. So I took the original 864x480 dvd and upscaled it with Video Enhancer 1.5x to 1296x720. When I opened both files in VLC and made them both full screen on the same time placement of 1 hour into the movie, the video alt-tabbing between them looked basically identical. Though the original 864x480 looks sharper before it's full screened. So I guess Video Enhancer does a good job at resizing, at least equal to what VLC does when it full screens a movie making me think there is no point in upscaling and loosing the original fidelity permanently and just let the hardware upscale as needed.

Thanks for the input.

Unless you changed the default VLC uses your graphics card's scaler which is usually a bicubic filter. Video Enhancer should do better than that. It should give sharper edges and less aliasing artifacts on near horizontal or near vertical edges.
