QT Broadaster from Blackmagic capture card?

Can QuickTime Broadcaster take input from Blackmagic's
capture card? Also, can Broadcaster work as an encoder
source to Real's Helix server?
Thank you,
Mike

Not if you are limited to sending back out HDV. The reconforming process is slow (as you have experienced).
in the for what it's worth category, this is why it's takes time.
Sony's version of HDV is formated into a 15 frame GOP (group of pictures). Simply put, this means there is one full frame (I frame) then 14 frames that reference the differences to the full frame. These reference frames do not contain full information and only make sense when compared to the last I frame and any intervening frames.
When you make a cut in this GOP, the chances are you are NOT editing on an I frame, you are cutting somewhere between them. This means FCP must generate an internal I frame at that point. As you can imagine this is an editing nightmare. That FCP gets it to work is truely a bit of wizardry.
When you are all done, FCP must re-conform the the footage, that is, generate a continuous 15 frame GOP structure from the beginning of the footage. Some I frames become reference frames and new I frames must be generated in the correct pattern. This is very computationally intensive and is totally dependent on processor speed.
So, If you want to speed up output to HDV, get a faster machine.
good luck,

Blackmagic Capture Cards?

Anyone using Blackmagic capture cards?
I have an Intensity Pro. Composite and s-video work fine. I
cannot get component working with a 720p or 1080i signal. FMLE
doesn't give me the option to select a resolution higher than
720x486. I haven't tested the HDMI input. Any ideas?
Maybe the problem is related to
this
post?

The video doesn't work for me.
I can get video output from the blackmagic media express software.
set to 1080i 59.94
The control panel for the blackmagic is set to 720p HD to SD letterbox 16:9 downconvert....
But when I launch the FMLE i just get a blank screen.
I'm told there is an ACC plugin to fix the audio isssu. HDMI is outputing sound at higher then 44100 so you need a plugin to deal with that...
But my probelm is with the video... I don't get a video stream....
Hell it would be nice if FMLE would support 1900x1080 and not make me mess around with all this....
anyone hanve any ideas?

Urgent: Unable to capture from TV Capture Card

Hello,
I'm Ashish Shukla. I'm writing an application in JMF 2.1.1b using J2SE 1.4.0 on Win32 platform on Intel Celeron 1 GHz processor which captures from the capture device. It works fine on Intel Create & Share CS110 Web Camera. But now, I'm try to capture from the TV Capture Card Pinnacle Studio PCTV TV Capture Card (Composite Video).
But JMF Registry is not able to detect the TV Capture Card (connected alone) & my PC hangs. But, when WebCamera is plugged in, JMF Registry detects it.
When Both WebCamera (USB port) & TV Capture Card are plugged in, then JMF Registry detects only Web Camera.
If anyone can help me resolve the problem. I'm very thankful.
Yours sincerley,
Ashish Shukla
Wah Java!!

Dear friend
I have a similar problem, did you got the answer...
I m trying to get video from the video capture card first from video then for composite then for ..... each port ... but it looks not to be easy ...

HD/SD Blackmagic Capture Card for G5 Quad Power PC

Hi,
Can someone give me some advice on buying a good, reasonably priced capture card for my G5 powerpc quad. Its still running very well and I'd like to extend its professional use for a little bit
longer as I suspect that the next incarnation of desktops is possible months away.
I'm assuming a BlackMagic card is best suited due to my limited budget but I'm open to suggestion.

You haven't said what formats you're hoping to capture, but I'd imagine one of Blackmagic's Decklink cards would work for you (Intensity Pro is not compatible with non-Intel macs).
Pay attention to the hardware requirements though: http://blackmagic-design.com/support/detail.asp?techID=76

Streaming multiple streams from multiple capture cards at the same time

Hi All,
I have 2 the same capture card. And I am trying to stream to 2 diffrent rtmp server. I start first one and no problem. But when I run second FME instance and select second stream card, first one turns to black and second one shows up. When I close second, first one again comes back.
What shoul I do for streaming multiple streams form multiple stream cards?
Best regards.

They are, yes, but I'm also working with multitrack sessions using clips made from various different sound files.
Ahh ok, use markers?
So, this sort of thing isn't possible in multitrack mode then?
If not, it sounds I'll have to "mix down" my multitrack session into a single file and set up the markers in Waveform Edit view.
That's an extra step I'd have to do, and after editing the multitrack session, surely some markers . . . oh wait, no . . . every time I output the new mix down file from the multitrack I'd need to redo all the markers. Drat . . .
Honestly, I am very new to Audition, but I'm about to plow into it, big-time, and I'm hoping for a nice non-destructive and fast workflow that'll enable me to output sets of sounds from the same multitrack session.
But, it seems like this functionality is currently missing.

Use Camera with capture card

Hi,
I'm using the camera method to view input from a webcam or to
view input from my capture card locally.
My webcam looks perfect, but I don't see any input from my
capture card.
Of course I've got input (tested with windows media encoder).
Should I activate or define the input (composite video,
s-video) or anything.
If yes.... How do I do this...
Thanks.
greetz Vince

Hi,
I have a similar problem. I want to use a webcam by the
composite connection and a dvd-recorder by the s-video connection
of the same capture card. How do I manage my flash application to
get the correct input source, that I have defined inside the
capture card configuration tool ?
Thanks,
Franz

How to display YUV stream from a video card into javafx and without JMF?

Hello,
I try to display in a player a yuv stream gotten from a video capture card.... Is there a means to perform this in javafx?
regards

Thanks for the pointer ; unfortunately I haven't find yet the alexfromsorkoland post about the topic you mentionned.
I'll try tomorrow another way of doing...
Basically I get yuv frames from video capture card... I've to translate these into RBG frame and then convert them into images I can display at a specific rate.
We can do this by using the hidden classes of JMF like com.sun.media.codec.video.colorspace.YUV2RBG and the javax.media.util.BufferToImage.BufferToImage. I've just now to find how to build the buffer needed for the YUV2RBG :-(

Capture card for HDV

Can anyone tell me if I have somekind of advantage from a capture card when working in HDV like realtime effects or even better direct output to tape without the time consuming conforming of the HDV material.
Core

I'm thinking about getting the Intensity Pro, and I have a Canon HV20, but I have a few questions for you.
Do the intermediate codecs look better when going from HDV to Apple Pro Res for instance?
If you have an HV20, do you know if capture is smoother? By that I mean does it find timecode more easily (when I batch capture, it's a struggle because FCP can't find the timecode half the time, and I have to keep telling it to retry).
How does the computer control the deck/camera? I didn't know you could control something over HDMI.
With the HV20, it records in 24p but really 60i where you have to take out the interlaced frames to make it a 24p image. If the HDV is captured as Pro Res, is it possible to still use Cinema Tools to remove the interlaced frames?
I have a ton more questions, but that's good enough for now
Thanks so much!

Capture Card Not in Audio Pulldown

I am using FME2 and a "Hauppauge WinTV PVR PCI II" capture
card. The card does show up in my computer's audio settings as an
audio source, but it does not show up in the pulldown of FME. Thus,
I cannot get the audio from my capture card, only video. Is there
any way to fix this, or can anyone give me an idea what might be
the problem?

Sorry about the double post. Looks like there is no option to
delete a post unless I'm missing something.

Capture Cards for HDV

Is it impossible to capture into FCP 5.1.4 without an AJA or blackmagic capture card? would this apply to imovie HD as well? I'm using an song hvr m15u deck....any help appreciated.
best

i am positive the i-link is "off" in the down convert section, and the output i have set to HDV. i've tried automatic, no better luck. such a pain. it feels to me like a setting in the deck, b/c i can't properly play tapes back on a monitor.
thanks again for the suggestions.

One FME instance for one Capture Card (or Stream)?

Any chance of running multiple instances so FME can encode
multiple FLV streams simultaneously? Assuming FME can Encode from a
Media Gateway (or Media Server) and not from a capture card.
Thanks
Ravin

Hi Ravin,
You should be able to run multiple instances of FME right
now. That said, encoding requires a lot of computer resource, so it
may not make sense to do this unless you have a very beefy machine.
Thanks,

BlackMagic Intensity Pro Capture Card & (3) 1TB Internal Hard Drives

Hello,
This is my first time using BM Intensity Pro. Prior to tonight all I used was FW400 & iMovie/iDVD.
I have now upgraded to Final Cut Studio with a BM Intensity Pro Capture Card and Three 1TB Hard Drives (7200 RPM with 32MB cache) - Striped as a RAID set to create ONE 2.7 TB HD for Video Storage.
I have a few questions that I would like some help with.
I would like to capture at the highest video quality possible.
I'm worried that Hard Drives wont be able to handle the capture speed or file size?
I ran the BM Disk Speed Test. I'm just not sure what all these numbers mean?
Can someone please explain to me what the following information is telling me?
Do the results mean that I'm good to go with uncompressed HDV via HDMI?
The first is my OEM Mac Hard Drive. The second is my 3TB RAID set.

I would invest in an external RAID controller.
You can find a variety of such from AMUG in RAID5/6 that will support higher sustained thruput.

FCP, Beta SP and Blackmagic Multibridge Extreme capture card

I'm having problems getting a video signal into FCP via a Multibridge Exteme capture card by Blackmagic Design. I currently have device control and am able to view footage already in FCP on an NTSC monitor so it appears as though the capture card is working. I have my capture setting set to blackmagic NTSC-10 bit (i've tried several different settings). I have the deck connected to the card through the component ports. Here are the specs on what i'm working with:
Mac Pro dual 3.0GHz Xeon
10 GBs of RAM
Blackmagic Multibridge Extreme capture card w/ breakout box
Sony PVW-2650 Beta SP player
FCP 5.1.4
Quicktime 7.1.6
OSX 10.4.10

Under System Preferences go to the Decklink Preferences.
Change the input from SDI to Component and XLR audio
Problem solved.

I have premiere pro CS6 and a blackmagic intensitiy pro HDMI capture card

I have premiere pro CS6 and a blackmagic intensitiy pro HDMI capture card will I be able to capture HD TV progrsms if I have a HDCP compliant monitor?

No.
As soon as you connect the HDMI cable from your cable box to the BM card it will be seen as non-HDCP compliant.
