XL-H1 Overcrank clip!

Barlow, ready when you are.

Hey Darrel,

I shot you an email. Call if there are problems.

[Darrell Essex]

Barlow, do i just drag and drop onto your webpage?

Barlow,

what version of compressor do you have? i'm not getting the exact same settings and it won't allow me to change a few - min spatial quality and min. temporal quality.

[Barlow Elton]

Compressor 2.0.1

[Barlow Elton]

Vince: If you're bringing in a 1080i clip, try this in the Inspector under frame controls:

Frame Controls: Custom
Resizing Control: Best
Output Fields: Progressive
Deinterlace: Best (make sure Adaptive Details is checked)
Anti-alias:0
Detail level: 0
Rate Conversion: Best (High quality motion compensated

barlow,
it worked fine without those settings. it did, however, create a quicktime with a frame size of 960x720. even though it was set for 1280 x 720.

either way, looks pretty nice. i will continue to experiment.

thanks,

vince

yeah, I had that result initially. Compressor can get confusing with DVCPRO HD because you might see a general description where it says it's rendering out a 1280x720 standard HD image, but because it's rendering into the actual sub-sampled 960x720 spec of 720p DVCPRO HD, it offers up a squished, squareish image. I went to the frame custom controls and told it to be 1280x720 there, and then it rendered correctly.

The download is done and thank you for the email that I received. Your files were and they are useful. And you prove that it's possible to get the same slowmotion as HVX200 does. Besides from 1080i, so better resolution or from 60i to 24p is there losses?

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.

By the way, I had been reading your post-report again and I'd like ask you if are you test it without going down to 720p, that is, with 1080?

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.

<<<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.

I'll have to give it a try. I believe what you'll end up with is 1920x540 fields interpolated vertically to be 1920x1080 60p, then converted to 1080/24p. 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.
