I've got two fold problem to tackle:

First, I've got a decent amount of HDV footage that I need to pull stills at as high quality as possible. Does anyone have any suggestions regarding removing DV artifacts and noise and sharpening up footage? I'm seeing Algoshop from Algolith that seems to address a few things but I'm curious if anyone has any home-brew solutions to this that would be both free and very effective?

Also, I'll have to be placing some cg work into some DV footage - what are your solutions for blending this well and getting proper artifacting & noise back in along w/ the composite?

Any thoughts on these would be great.. Thanks!!

I'm not really able to tell you a good way to remove artifacts from your footage, but i'm going to assume that you've made a short film and you're going to send it off to festivals.

You're actually supposed to have a set photographer, who takes still shots seperate to the film (or in your case, HD) cameraman. Those are the ones used for marketing, advertising, and in your press kits.

My first short film unfortunately lacked in the stills, and so i was forced to pull some from the video footage, and it's not pretty. It takes a LOT of cleaning, and even then the resolution won't nearly be where it needs to be.

DV footage (at least in PAL) is 1024x576 (assuming you shot 16:9) and you want your stills to be at LEAST 4048x3040.

Don't expect anything pretty from your stills this time around, but i'd HIGHLY recommend hiring a stills photographer next time.

I don't think you can remove DV artifacts automatically, either.

Adding DV artifacts to CG footage is easy though - just compress the clip as DV. :)
You might also try things such as edge enhancement (sharpen).

DV footage (at least in PAL) is 1024x576 (assuming you shot 16:9)...and it's not even that high, the camera only shoots and stores 720*576 (16:9 or not). The 1024 only comes if you stretch a 16:9 clip to square pixels in post.

search and try demo of after effects or premiere plugin called magic bullet.

it is a magical tool that help you to deinterlace, remove dv artifact and change the look of your shooting by many parameters.

most of software that load after effects plugin can use it, and before to buy you can try the demo.

it was developed by the guys of orphanage, ex ilm employer that work a lot with video and develop many tools to change video look to movie look.

Magic bullit indeed is one hell of a tool... done some corrections with it, haven't seen another plugin or program doing it better.
