filtering out edge enchancement
 

Hello everyone - I apologize in advance if there is already a post on this. I ran many searches and came up with nada.

I'm currently planning the (post editing) post production for a documentary shot on a JVC HD1 (quickly: this was a budget production that recently got more support, so we are trying to fix some things without looking tacky).

Being a consumer camera, the HD1 has built in edge enhancement that cannot be disabled. From what I understand, it is essentially a cheap unsharp-mask filter. This has resulted in many hard (or pathological) edges in many scenes that are sometimes visually garish, but mostly they trip up the mpeg compression and cause a lot of bad noise.

We are editing CineformHD intermediate, so the goal is to filter out as many problem areas now as possible, so that they do not reappear or become compounded when we compress again for DVD. We're planning on using Algolith's tools to handle all of the chroma/mosquito noise. Does anyone know how to un-filter an unsharp mask? Or at least minimize the effects?

Thanks in advance.

whats your NLE?

Can you post a still frame example?
There are some techniques I can think of, but it's easier to help knowing what app you're using and what your specific situation looks like at the moment.

We're editing on a Premiere Pro setup with Cineform AspectHD. Some titles and things we've been using AE, and we'll be doing any image fine tuning with it as well. I'll get some screenshots up shortly.

Thanks,

Will

Okay - i set up a flickr account to share these photos. This set is from one particularly bad shot, since most of the sky is blown - but this is common when shooting video, since the only other option is crushing the subject. You can't always get the shot you want when shooting for docs, so we're trying to make the best of what we have...unfortunately, that means working with some shots that look like someone outlined everything with a magic marker.
