Initially the 'Intensity' card had only HDMI connections, while the
current 'Intensity Pro' since late 2007 got a breakout cable for
component connections. I would expect the latter model is what the Linux
announcement mean with 'Intensity', though I haven't asked myself yet.
I don't know if the tech specs does clarify more
Analog Video In/Out Component, NTSC, PAL or S-Video.
Dual Rate support HDMI and Analog Component switches between
high definition and standard definition.
HDMI Video Sampling 4:2:2.
HDMI Color Precision 4:2:2.
HDMI Color Space YUV 4:2:2
And from features in the pdf brochure
* HDMI and Component connections switch between
high definition and standard definition.
* HD format support: 1080 lines at 59.94i, 50i, 720 lines
at 50p and 59.94p. SD format support: NTSC/PAL and S-Video.
* True uncompressed YUV 4:2:2 video capture and
playback for high-end production quality.
* Compressed video capture and playback on
supported platforms. Edit in DV, DV50, JPEG,
HDV and DVCPRO HD files on Mac OS X. Edit in
DV and Online JPEG in Adobe Premiere Pro
My own Sony HDR-FX7E HDV camcorder works internal with 1920x1080, and
should according to Steve Mullen's Handbook be able to send raw output
from its 3CMOS sensor to HDMI out as uncompressed 1440x1080i at 4:2:2.
HDV (m2t) on tape at 1440x1080i (1280x720) with 4:2:0 sampling is
compressed MPEG-2 video at data rate 25 Mbit/s (the same as DV/SD) or 15
Mbit/s. I thought it would be smart to have an option to save raw video
on harddisk at moderate compression (MPEG-2 or H.264) which utilizes and
also is compatible with Blu-Ray (BD-R/RE AV) max data rate of 40 (36)
Mbit/s for video.
Regarding Cinelerra's native quicktime for linux codec yuva 4:2:2 I wonder:
1. Is this a standard documented Quicktime format, and do we have a link
to such reference documentation we can point Blackmagic Design to?
2. While output video file formats from Cinelerra are mentioned here and
there, I haven't seen an overview of which video file formats that can
be opened (imported) and are supported and work well for editing.
What about container type and compression levels? Though I haven't
started to edit yet, I did a couple of simple tests and opened both DV
and MPEG-2 (SD from DVD) files, which seemed to open ok. In additon I
have heard that native HDV (m2t) should work.
But what about other SD and HD files at higher quality (4:2:2 and
datarate) in MPEG-2 and MPEG-4/H.264 moderate compression ?
