captured direct from hdmi yet?

[jetpro]

Has anyone captured from the HDMI out into a macpro with a blackmagic intensity card yet? Was there a drastic improvement? What was the work flow, was it as simple as log and capture in FCP to prores or uncompressed?

There's a studio portion of a show I'm producing and I'm wondering if it would be worth the $250, and the hassel of bringing the mac.

Has anyone figured out whether you can captured 24p through the Intensity?

[jetpro]

i haven't been able to find any definite answers on the 24p issue. there doesn't seem to be an in depth reviews.

[David Saraceno]

Web site says 720/60 only

[jetpro]

which website?

blackmagic's site says:

1080i50, 1080i59.94, 720p50 and 720p59.94.

Why should be HDMI be a drastic improvement over components?

it's my understanding that HDMI will give you 422 color space and a uncompressed image from the camera.

now if it's a drastic improvement over the component out, I have no clue. Also either way I'll need to get the intensity or a different card that can capture via component cables.

I got the IntensityPro and captured via HDMI and Components - no difference.

The only difference, audio comes within HDMI - for component you need seperate audio cables.
But the video signal is basicly the same HDMI=YCbCr Component=YPbPr

....and I´m an obcessed pixel counter.

Inside the computer it will be converted to RGB anyway, no matter if it comes of HDMI or Components.

Unless we don´t have cameras and cards that can handle the xvYCC or Extended-gamut YCC color space, you will not see any difference.

Workflow is pretty straight forward. Set uncompressed or Poto JPEG and capture. That´s all - ready to use.
You will have to make a Black Magic timeline to use it in realtime. Signal quality is superb.
If you want machine remote you have to buy the Deck Link.

so how does the AVC Cam ProRes encoded footage compare to the uncompressed capture from the HDMI out on the HMC150?

instead of capturing uncompressed, can you capture to DVCPro HD? what are the frame rates and options?

[Postmaster]

I never saw a codec that stisfied me (thou Cineform come dammed close).
Every lossy codec that compresses, does that by throwing away information.
You may come to the point when you need that information - like color grading.

On the other hand, there are some verry sophisticaded codecs out there.
Cineform, ProRes, Avid and what not.

Personly I don´t like DVCProHD and I don´t like any GOP codec that´s why I use uncompressed when ever posible - but I´m pretty anal here.

In the real world you can work pretty good with most of them. Just make sure you keep your workflow straigt and don´t jump from one codec to an other too much.

If your camera is doing DVCPro HD than capture and edit in that format and then output to - whatever you need.

If you plan to do excessive post work and color grading, it´s better to capture and work in a lossles or almost lossles (Cineform) 10 bit 4:4:4 intermediate format.

The HDMI or Component out of a HMC150 (if captured lossless or almost lossles) is way better than recording DVCPro HD on P2 Media.

I'm referring to anything 24p.

Isn't supported.

[Postmaster]

Don´t know how that works in FCP but there is a Black Magic preset in Premiere that says it does 24p (pull down from 60i)

Frank

[jetpro]

so what's the conclusion, capturing live from the camera straight into FCP better/same/worse?

[zcream]

Quite a few camcorders have recently given a xvYCC signal via HDMI. Are you aware of a capture card that will take this signal without clipping ?
Turns out the Blackmagic does indeed clip the signal.
