Lossless way to convert (up-convert was the wrong word) 720p to 1080i? - does it exist? im doing this from the HD200.

Why not capture the footage as 1080i from you component out's? Do you have a way to capture live component in (even from the tape if needed).

If you have HD SDI input capability then you can use Convergent Design's HD Connect LE hardware to cross-convert the HDV1 720p stream to a baseband 1080i HD SDI signal. It's all digital so you won't have the problem of D to A conversion that you'd get using the camera's HD component analogue outputs and the conversion is real-time, of course.

In addition to the HD-Connect LE, we'll have the HD-Connect MI out this week for $695. It does HDMI -> HD/SD->SDI out of the HD50 deck. You can easily setup the box to output 1080i or 720p.

I've used the HD-Connect LE to go firewire out of cam to HD-SDI upconvert in to deck before and it works flawlessly.

I had previously tried several different solutions and this by far was the best. I'm sure you could probably get a demo from a local retailer and do some test runs for yourself.

Does your NLE do the conversion on the timeline? Why not let the NLE do the work? Converting to 1080i is not that much of a hit on your 720p footage.

mpeg streamclip should be able to do this and its free.
