Uprez SD to HD

aldo12xu wrote on 7/24/2008, 2:10 PM
I am working on a project that will have 80 % HD footage and 20 % SD footage. I realize that I can work with both SD & HD in the timeline without a problem and render out the final result back to HD tape or as an HDV mt2 file.

But what I'd like to do is upconvert and enhance the original SD footage before I put it in the timeline so that it approaches HD quality. What I'm hoping to get is a less noticeable difference in quality when I'm cutting from the HD footage to up-rezzed SD footage. As it stands now, the difference between the HD footage and original SD footage is quite marked. I guess I'm looking for a software program that's equivalent to the upcoversion that some DVD players are capable of.

I found these two programs, but they're over $300 each. Any cheaper alternatives out there?

Digital Juice has "Topaz Enhance" on sale for half price. There is a fully functional 30-day trial available on their website. I've been playing around with it and comparing it to Instant HD Advanced. The controls are very similar and the results seem very much the same to me (though I did nothing scientific in my tests). What I like about Topaz Enhance is that it has quite a few other tools included that seem very useful including noise reduction (seperate from the HDV upscale plugin). Their user manual and tutorials are very good as well.

Another program is Video Enhancer which is a standalone and only 29.95. I played with it but had trouble getting it not to stretch my videos in wierd ways. I'm sure it works I just could not find the right combination. Also there is no way to adjust the position of the video like you can with the others when in After Effects.

They show some quality comparisons with other programs on their website but when they compared it to Topaz Enhance they must have overtweaked the settings because I am not having the problems they claim Topaz has. Like any of these products make sure you try before you buy.

Be aware that most uprezzing programs really only perform their magic properly on progressive footage. If you have regular NTSC or PAL interlaced footage, you won't see much difference between these programs and just rendering the interlaced SD from the timeline in Vegas. At least that has been my experience.

Also be aware that there are some pretty good free VirtualDub and AviSynth uprezzing plugins that are quite likely to be as good as the commercial uprezzing programs.

Thanks for the tips, guys. Topaz sure looks good and would definitely have been tempting if it came as a plug-in for Vegas. I'll give Video Enhancer a try.

Please share with us exactly which free plugins you are referring to. (provide links if you can please) BTW, super-resolution is the technical name for this process, as it differs slightly from uprezzing.

I've had pretty good luck with the simple Lancos 3 uprezzing filter in VDub. Especially combined with the interlace field separating filter. I just separate the interlace fields to either side by side or one on top of the other, then resize with the Lancos3, and refold the fields back together. That's taking for granted that you want to uprez regular interlaced video.

As far as Topaz Enhance goes, it is probably really good. I have Topaz Moment which does something similar in order to capture higher resolution stills from video and it works quite well.

Does anyone know if this works with Cineform?

Not sure what you're asking. Topaz Enhance requires a host like After Effects so the question is does the host you are using support CineForm. Topaz is just getting frames served to it from the host and could probably care less what the original file format was.

I tried the demo with Boris RED 4.3 and it seemed to work although it is not a "supported" host. I did get it to die when nesting Comps so it may have limited use with RED since the filters depend on Comps to apply more than one dynamic filter at a time. I deinterlaced some CineForm footage and it was fine, but this is because RED supports CineForm not Topaz Enhance.

I could not get it to uprez with RED. That could be a limitation of RED or just my not understanding how to get RED to accept the larger format. All it did was zoom with the original dimensions. :( I'll have to play around some more when I get time.

OK, so it's just an After Effects plugin. I'm not interested anymore. I thought it was a stand alone program like Topaz Moment.

Topaz Enhance also works in Premiere and Final Cut. You have to be careful how you stack the filters when using it in AE so it's worth reading the manual. Also in Premiere certains settings need to be right.

OK I got the uprez working with Boris RED. The key is to create a container, add your media to the container, then add Topaz as an effect on the container (not the media) and the media will be uprezed to fill the containers resolution. (Duh... I knew it was something I wasn't understanding) It rendered extremely slow (several minutes for 1 second of video) but it did use all 4 cpu's on my quadcore.

So will everything downstream be affected os just in that container

Only what you place in the container. All I placed was the one video. Of course, you could place that container in another contain or even place the whole comp in another comp. In fact, using nested comps is how Topaz recommends that you use their tools. Unfortunately, RED gave an error and dies when I tried to nest comps using the Topaz tools so there may be a problem there.

So, how did that one second of uprezzed footage look?
