Does anyone know of a plugin or program which will remove video compression artifacts from a DV image?

You might want to take a look at SmoothKit:

<http://www.revisionfx.com/smok.htm>

It's normally $169, but it's on sale right now for $89:

One of the must have products, The Magic Bullet Suite, makes propably the
best DV-compression artifact removal I've ever seen.

You know the did use it in Jackass: The Movie, because it was filmed mostly
on DV-cameras, even with ones with only 1ccd... The quality is outstanding.

Also look into Grain Surgery: <http://www.visinf.com/gs/ae/>

But I don't know of any dedicated deblocking filter for AE.

Apple has a nice Total Training video on how to reduce JPEG artifacts here:
<http://www.apple.com/creative/resources/ttphotoshop/603jpegartifacts.html>

you could apply that to video pretty easily.

Thank you so much. This looks like the solution. Unfortunately I have a PC and the tutorial refuses to open. I am assuming the page is formatted for a mac.

Best Regards,

It uses Quicktime... which you may not have installed. Go get the Windows version here -> <http://www.quicktime.com/>

Thank you once again, the new Codec allowed the tutorial to play, although only half the tutorial plays for this particular download the type of artifacting they show on the screen is quite different than the artifacts I am dealing with. The compression artifacts in our image are the fine wire screen blocky artifacts, although I imagine that the same process may work for both.

What exactly are the compression artifacts you want rid of?

I made a plugin that makes progressive PAL DV footage more keyable by swapping around the chroma (since PAL DV is 4:2:0 within a field, you get mice-teeth chroma on progressive footage, my plugin tinkers that)

You can get it here <http://www.master-zap.com/aeplugs/> (sorry, no page yet, just a directory ;) )

anyone who invents a way to make DV look uncompressed will be a VERY rich man.

Looking outside After Effects you can always try to take a look at virtualdub -

<http://www.virtualdub.org/>

Which have a bunch of smoothing & noise reductions filters, everything for free..

For the newest and maybe most sofisticated, a company called Alogolith have made a plugin called AlgolithMNR for removing digital artefacts. Still only for shake & fusion though - but the plugin is as said brand new -

The de-artifacting algorithm in Magic Bullet is pretty good, but it aint cheap.
