Super resolution

I would use it, but they don't give a free trial of that without the lines going through it.

You're much better off using the avisynth plugin than the app.

Agree! (even if you must take it cum grano salis because I'm an old dinosaur who likes to actually write commands...)

@ Andrea & Valeyard - Aside from the added benefit of being able to do any "post-processing," once the material has been SR upscaled, why are you guys of the opinion that it is "better" to use the avisynth plugin? Is there some benefit to this or is this just your personal preference?

[spoRv]

Maybe because it's possible to add further filters, and encode the final result in one go - dunno if avisynth filter is actually better/faster/nicer...

[Valeyard]

Because you can embed it in your script however you want and call it as many times as you like (DrDre's script for instance calls it multiple times).

I would use it, but they don't give a free trial of that without the lines going through it.

Yeah so VE is better for the trial/evaluation of the product, but if you want to buy it the plugin is the way to go.

Also I know a coupon code that reduces the cost by 50% of any of Infognition's products. Code is STDNT.

Should I use filters such as sharpening, deinterlacing etc. before doing Super Resolution with Avisynth or afterwards?

Sadly Super Resolution doesn't seem to have big results on low quality sources: http://screenshotcomparison.com/comparison/136331

I know little about sr. Just trying to find out about it for myself. One thing I do know is you have to ivtc before using sr. Working with frames is better then fields. Sharpening I would do at the end but that's me

[jerryshadoe]

IMHO, if you are working with any interlaced footage, you should de-interlace it before you do any additional work to it.

So, in this case, de-interlace, then change framerate if needed, then SR, then any/all other filters, then resize to final dimensions, and then grain plate last...

Care to share a screenshot comparison of your results?

I haven't tinkered much with the plugins in VE. I looked....

Having read all of it in daylight, I know realize it might not be the fastest way, given that there's no realtime feedback when adjusting the settings on a filter. The plugins themselves are just virtualdub plugins. And some of them crash. Probably best to do all the other stuff in another program that you'll use anyway to give you flexibility of choice and fine-tuning. So basically disregard the... whatever I said.

So another question. Would sr help with macro blocking that wouldn't be in the original master. I have a few hdtv 1080i mpeg 2 broadcasts that have macro blocking. Just wondering if the comparing frames that sr does would help without having to blur the blocking

[jerryshadoe]

Keep in mind, YMMV, but in the tests that I have done, SR doesn't cause any EXTRA macro-blocking during the upscaling process, HOWEVER it does NOT really "filter" out any macro-blocking that you may have in your source. There have been a couple of sources where it doesn't look as bad as the original but this is usually when upscaling "non-standard" resolutions (i.e. non-divisible by 16) and doesn't always happened. For getting rid of macro-blocking, I have had the best results using an "unsharp mask" and usually try to have two different sources than I can overlay with each other which helps mask the macro-blocking.
