Weird Gearshift problem

If I capture m2t files and render with Gearshift, then view using 1394 preview, I see a full resolution picture on anything that isn't changed regardless of my preview setting. This is exactly what I would expect and extremely cool. This is in fact the way I usually work: at reduced preview resolution, which I only see during overlapping transitions and animations. However, if I capture cineform codec HDV and render proxies from this, what I see over the 1394 preview is an image rerendered at whatever the preview resolution is set at. I can't for the life of me figure out why.

If I mix proxies generated from m2t files and proxies generated from cineform files on the same track and view via 1394 at draft resolution, the proxies generated from the m2t files will preview at full resolution and the proxies from generated from the Cineform avis will preview at draft resolution. If I look at the properties of the proxy files, they seem to be exactly the same. If I view them from a media player they look exactly the same. There's just something about the proxy from the Cineform file that makes the 1394 preview rerender.

What I want to do is capture Cineform avis using HDLink, generate SD resolution proxies for editing, preview this at "good" resolution, and see full resolution except at the overlapping transitions (which I only use sparingly). As things stand, I can't do this.

How are you making your proxies from the CineForm files?

OK, here's an update after a little experimentation:

If I run Gearshift to make SD proxies for Cineform avis while the project properties are set to NTSC widescreen, the proxies preview at the set preview resolution even for unchanged parts.

However, if I make SD proxies with Gearshift while the project properties are set to HDV then switch the project properties back to NTSC widescreen before editing, the proxies will preview properly: at full resolution for all unchanged parts and preview resolution just during overlapping transitions.

I'm making the proxies by browsing the files to convert, selecting "all files" instead of "m2t", selecting the Cineform avis I want to make proxies from, then running Gearshift to convert the proxies. The reason I'm doing this is to save hard disk space and rendering time as it is more efficient to capture Cineform with HDLink than it is to capture m2t files and convert to both Cineform and SD proxies. My PC is only up to editing Cineform at reduced resolution and I'd rather work with proxies I can see clearly.

I'll have to dig into this more deeply. You're doing something GearShift wasn't designed to do, but if we can make it more useful for folks by incorporating this workflow, we should. I've never made a proxy from CineForm, simply because it hasn't made sense for me to do so, but I can see how some users might benefit from this workflow to some degree. Also, you might want to remember that the GearShift support forum can be found here
