No problem Leuname. Glad the clips were helpful.

Losses? IMHO, no. Maybe the fact that it's going from HDV to DVCPRO HD, but you can get XLH1 footage into lots of other formats (like uncompressed) in order to keep recompression at bay. Maybe one of the codec experts can help me out here, but I think because the HDV is subsampled down to smaller frame 720p, you get 4-2-2 color anyway, and that's to say nothing of acquiring through live SDI tap.

That program does a flawless job of converting to 720p if you use the right settings. Maybe the only loss is simply that you're losing resolution the H1 provides by going down to 720p, but 720p is a very good HD format and it's nice to know that the H1 can look terrific in this realm too.

Oh yeah...the main loss: time. The renders can be dog slow, but that may be a small price to pay for all the flexibilty.

Good report. Thanks again.

Is it possible to handle with that resolution in order to get slow down from 60i/50i to 24p without left 1080?

And in this case to have more resolution than 720p mode with the HVX200?

Without speaking, of course, of the higher XL-H1 1440x1080 CCDs vs the lower HVX200 960x540 CCDs -- pixel shifted or not.

useful observation

<<<Major differences at my point of view, codecs away:

HVX200

color + filmic dynamic range + wide latitude + native progressive scan = better film-like look

XL-H1

native higher resolution + superior lowlight & noise handling = better run and gun >>>

Leuname, thank you for a really practical insight.

I need more of them whenever you feel inspired by your experiences.

So the motion will look pretty much like 2.5 "overcrank", but not necessarily all that sharp. The actual detail and results I think will be very similar to taking true 1280x720 and bumping up to 1080p.

Regardless, it can look pretty good and reasonably slow for dramatic purposes.

You need to end up with 1920x540 filelds interpolated vertically to be 1920x1080 from 1080/60i, right?

Why not better if 1920x540 = 1,036,800 is higher than 921,600 (1280x720)?

So the pretty look results that you have been to prove that it's possible to get slowmotion from XL-H1 through HD-SDI to DVCPRO-HD at 720p, it means that will it be viable to have it from any kind of 1080i source like 1080i Canon's itself or any Sony's HD series, Cinealta or HDV -- right?
