Neo, Aspect, or Prospect???? which one
 

I am using Adobe PPro CS4 and would like to move into the cineform workflow. Which product would best suit my needs? I work entirely in HDV and do not see myself using HD-SDI in the future at the price point I am at currently. I use Magic Bullet Looks for color correction within PPro. I need something that will help take the HDV render times down and give me the best possible quality. Once finished with the project I archive it back to tape as HDV, burn to Blu-ray disc, and also to an SD DVD. I would really love the footage to be frame accurate within the project so when I batch capture everything is back in place (incase something needs changing later on).

Any info as to which is best would be greatly appreciated. I noticed that Cineform states that Aspect HD works with Premiere Pro realtime but whats the difference between the rest?

Thanks.

Aspect should be all you need if you are editing entirely from HDV. The Prospect options are for full raster cameras (1920), SDI I/O, and other such things.

Key thing to note is that CS4 is not yet supported by pretty much any third party vendors (Matrox, AJA, Blackmagic, Cineform, etc.) but they will be in a month or two. So if you are totally wedded to CS4, continue to edit in native HDV mode for a while.

Adding to Mike's comments.

Aspect HD and Prospect HD/4K are optimized for Adobe Premiere Pro on Windows. They include all features of Neo, but the Aspect-Prospect products include CineForm's real-time video processing engine optimized for real-time, multi-stream playback within Premiere Pro while reducing the need for rendering.

Since you'll be working in PremierPro you'll want Aspect/Prospect.
Aspect works great with HDV.
Based on your requirements it doesn't sound like you'll need Prospect.

Prospect HD also provide all the 32-bit float support, so it you plan on extensive color correction, it is the better choice even for HDV sources.
