It is true that the live-camera video out of the HV20 is exceptional (for a $1100 camera). You do get the full 1920x1080 422 YCbCr video which has need seen a compression cycle of any sort. At a shootout at NAB many people were hard pressed to tell the difference between the live HV20 and some very high-end ($100K+) cameras. Mike Schell |

I wouldn't presume to tell you anything (if just for the reason of number of posts alone - not even considering that you are an industry professional), but I was specifically talking about capturing from tape. I would think that as a practical matter going from 1440x1080 to 1280x1080 would be offset by also going from 4:2:0 to 4:2:2 color and going from a 25Mbit compression to 100Mbit; i.e., wouldn't DCVPRO HD have higher quality potential than HDV? As far as all of the 24p stuff goes, I'm not really interested in it. I bought the HV20 primarily for its HDMI port, to use as a feeder for FX1 and Z1 tapes (and as a family camcorder). |

im not sure by reading this thread if there was ever an answer, but the canon HV20 does indeed work perfectly with the black magic intensity HDMI input. we caputured a bunch of footage using the mjpeg codec at 24p (the camera wraps the footage as 60i of course). weve been doing pulldown in after effects because premiere cant manage that. the quality of the codec is amazing, infinitely better than HDV especially on fast motion and high contrast. what would rock now is if the card could do pulldown on the fly. im in the process of designing a small box that will connect the black magic card to a notebook express card slot (its basically a cable with an expresscard on one end and a x1 slot on the other). this should make everything nice and portable for shooting with the mjpeg compression. im working on a way to get a notebook to save uncompressed as well, but thats more challenging. i see other are concerned with portability as well, so if anyone would is interested in this little express box, post here and i may be persuaded to make it a priority project. later, terence |
Count me in, Terence. I've been looking for an Intensity type option that I could take on the road.

Is the capture footage 1920x1080?
Is it possible to capture on a PC, using Vegas? or Cineform? Do you support the PAL HV20, 25p? I would be interested in your notebook solution. Patrick |
- Is the capture footage 1920x1080?
yup, its full 1920x1080 60i. it bypasses the tape compression if you capture live. - Is it possible to capture on a PC, using Vegas? or Cineform? never used vegas or cineform, ill leave that to someone else to answer. we captured in adobe premiere pro 1.5 and cs3. both are fine for 60i, but for 24p you have to save out and do the pulldown in another software such as after effects (pain in the a**). - Do you support the PAL HV20, 25p? no idea here, dont have pal settings on our camera. - I would be interested in your notebook solution. 2 already eh? ill mock up a spec and estimated price for this box in the next week. its a passive device so it should be relatively cheap with enough volume. terence |

Hold the presses...
I thought the Black Magic Intensity card had HDCP issues and it did *not* work with the HV20? Are you saying that it works!? What changed? Was there a new firmware release for the HV20? Software update for the Intensity card? If this is not an April Fools joke (a bit late) put me down for a laptop solution as well! Thanks! Rob Robinson |
our hv20 was bought last week along with the card.
its possible that older versions of the cam/card didnt like each other, i have no idea. i just know that what we have works flawlessly. the notebook thing isnt an april fools joke. the expresscard slot on most new notebooks is a pci express x1 and usb 2 interface combined. its possible to map the pins back to a standard x1 slot with a little effort. thats what im doing, then stuffing the x1 slot in a small case sized specifically for the intensity and using a cable to connect back to the pc. it will be something like a portable 2.5" hard drive in size/shape. ill try to get a mock up done asap, but im swamped with work til mid next week so i doubt it will be before then. terence |

yup, thats what motivated me to do this. thats ones big and clunky and needs external ac power. mine will be more usable for carrying on your person and dedicated solely to the intensity.
it should also be cheaper (i hope) terence |
Terence... put me down for one too.... :-)
Also, on the Intensity card, is it the standard or Pro card... what software version are you running with the card? |

were using the standard, dont have need for the analogue (i imagine some people do though) driver version is 1.3

Terence,
You wrote : "this should make everything nice and portable for shooting with the mjpeg compression." be warned that the M-JPEG codecs in general have a lot of edge artifacts, therefore are not commonly used today in post unless very high data rate are used. Attached is a comparison but CineForm High quality and the Blackmagic MJPEG codec. Here is right up by another user that compared the to : http://www.dvinfo.net/conf/showpost....56&postcount=1 Please make sure you allow user to select nicer codecs. P.S. CineForm has pulldown extraction to 24p from the Intensity card as a feature of all our products. |
Quote:
yeah, i second that. use cineform. otherwise when i buy your box i'm just going to have to go through an extra step to convert it to that. :) |
hey there.
im just making a box :) it will be up to the user to config their laptop the way they please. compression(of some kind) is only a must at this point only due to hard disk performance limits (25-30mb/s sustained write for the fastest notebook drives). if someone would make a notebook with 2 express card slots, this would not be an issue as a "pocket" raid system could be added. does cineform work with the canon hv20? from what i read on your site, you need prospect hd to get the 10 bit 1920x1080, and that canon 24p was not supported "yet". as well, small notebooks are usually limited to 1.6-2.1ghz dual cores at the moment, your minimim specs on your site would stress these little ones to the limit. we were looking into cineform as a possible solution for pulldown removal on the fly. any thoughts? terence. |
me want express box. uga uga....

For capture a user could use NEO HDV which will encode to 1440x1080 (resizing the source to fit the encoder license) or NEO HD for 1920x1080. Both less expensive than a Prospect HD licence for Premiere. As for the minimum system specs, they are old, modern systems do very well at lower clock speed. I would expect most 1.8GHz Core 2 Duo laptops would hande 24p encoding. My 2.33Ghz Dell laptop encodes 1920x1080 at 36+fps for high quality and 39+fps for medium -- this is for extremely demanding StEM footage, data from consumer cameras is easier. |
Hey Terence, put me down for one of those boxes as well. Sweet.

I believe it has been said in other threads that most of these cameras only output 8bit over HDMI anyway so cineform not supporting more wont be a big thing, if anything, that's less data to deal with. Or is cineform expanding it the 8bit to 10bit anyway? I, too, am very interested in whether core2duo mobile processors in the 1.6-2.13ghz range are adequate for capturing from the intensity from an hv20. Perhaps in low quality mode? 2.33ghz core2duo mobile cpus are $600+ just for the cpu, and the 2.0 ghz version is like 1/3 the price. I guess overclocking might be an option for some. But if it is not necessary for capturing, it could make a big difference. I am interested in building a portable miniITX capture device using the intensity, so knowing exactly what cpu will give us the results we want for the lowest price will help a lot. Unfortunately I doubt many ITX boards can be easily overclocked. As much as i'd love to buy neo hd and an intensity card and test it on various mobile processors, I dont think I have the disposable income to afford it if the cpu's I buy dont end up being enough for reliable capture.
NEO HD seems a bit pricey even for all the things it does. David, any cineform fanboy discounts for posting on forums all day about how great cineform codecs are? :P Is it possible to use NEO HDV to capture from the intensity? will that just force resizing to 1440x1080? or are there also other limitations? |
btw i think i tried using some trial cineform software to convert 24p@1080i hdv to cineform 24p (with inverse pulldown) on my core2duo mobile 2.0ghz cpu and it seemed to be able to do so in a little less time than the length of the clip (just faster than realtime). It was close, so im not sure I'd trust it, but capturing from HDMI might be easier on the cpu since its not decoding hdv while encoding cineform at the same time. it was something like 20sec to convert 27sec of hdv. im not sure if im remembering some of that correctly, but its a start.

Yes Noah, it is very good sign that you can convert an MPEG faster than real-time. Your laptop will have no issues live capturing. As for the cost, there is always someone you thinks we charge too much, yet last month the equivalent to NEO HD was $3000, and still a good deal, so $599 is a steal. Remember there is not equivalent on the market today. As for 8-bit vs 10-bit, we upconvert all sources to 10-bit, it just looks better. Yes NEO HDV ($249) will also work with the Intensity, automatically resizing to 1440x1080.
We have plenty of fanboys, we don't need to give up $$$ to recruit more. ;) |
Hey Blackmagic company folk, since you're reading this thread, I hope you have noticed the lengths we are going to in order to get an Intensity card attached to a laptop... why don't you just make an Expresscard version?
Bruce Allen www.boacinema.com |
david, ill try the demo for neo hd and test the pulldown removal on the hv20. if it works and can be happy on a 2ghz core 2 duo, then it sounds like a very viable option.
price is always a concern, but you have to weigh it against what you are gaining. realtime pulldown removal and higher quality compression can justify $600 for alot of people who need to make money of the process. im sure ill get a few people telling me the expresscard box is too expensive and want a fanboy discount :-P terence. |

"Intensity is currently not compatible with the HV20's HDMI output for capturing 1080 video. We're still investigating." Perhaps then there is new firmware on your HV20? Can you verify the firmware on your camera or perhaps the serial #? I wonder if Canon was able to change the firmware on newer shipments? Thanks! Rob Robinson |

I don't know if anyone already asked..but Terence, can you provide us a sample video from your test shoot?

I know cineform is a steal considering there really isnt anything else that does what it can do. I just wish i could buy it now, but I probably wont be able to justify it until I have a real project that requires it. If it worked for OSX, I would have tried to get the company I work for to buy it instead of buying our expensive xserve raid for uncompressed HD. Unfortunately "uncompressed" seems to be a buzzword for a lot of people. the buzzword really should be "visually lossless". of course we had to downres and convert all our 2k dpx's to uncompressed HD just to get one stream to playback on our new $20k edit station. Makes you really appreciate what prospect/neo 2k does.

I've been monitoring the Blackmagic site daily for a software/firmware upgrade to the Intensity card. Software version still at 1.3 which was released March 21, 2007.
http://blackmagic-design.com/support/software/ |
I'm a HV20 user looking for a laptop, possibly backpack contained, HDMI uncompressed solution. So, count me in!
|
So how does what's being proposed differ from this...
http://www.magma.com/products/pciexp...ox1/index.html Also, Terence, can you please tell us what the firmware version of your HV20 is? |
that device has been mentioned already, the differences are size, weight, power, and price. otherwise, yes, they do the same thing.
frimware version will have to wait till tomorrow. im actually in toronto, and the camera and card is in LA with my partner on this project. works out great :). ive ordered another bm card and will likely pick up another camera for testing next week so i dont have to do the long distance thing anymore. terence |
hmm, where would we find the firmware version. ive noticed that canon has not released any updates for this camera for public download.
terence |
ok, so we tried the neoHD demo, and there is no pulldown removal option for anythig but SD dv. is that because it doesnt recognize the camera? or is the demo older and not have that function?
terence. |
