Thread: Major Magic Lantern 550d update!

  1. #251

    Default

    So I was going to get the t2i and put the Magic lantern on it to get clean hdmi output 1080i for a solution like the Intensity or that new black magic capture station. That was the only reason. So my question is the 7D does this anyway, and the reason I was getting the t2i or ML is not valid as I already have the same capability in the 7D. Or does the t2i with ML offer better edge to edge without the pillar bars straight 1080i out of the hdmi port and I should still get it anyway.

    Like I posted before, you will get the bars unless you crop the image and give up about 16% of the frame. The clean output refers to the fact that there are no red dots, white boxes or other icons on the screen. Same with the 7D I believe only you can record with it while keeping the HD output.

    Okay so me buying the t2i is stupid as I get the exact same thing wit the 7d. So that saves me money. And I already own an hv30 so this saves me money. Thanks guys.

    Zooming on the TV would lose resolution. It appears the image above is a 3:2 AR image shrunk into a 16:9 box, getting both letterboxing and pillarboxing at the same time.

    I've found no way of getting a full, realtime (not recorded) 1920x1080 out of my unmodified T2i...

    Just butting in for a second. This Blackmagic HyperDeck Shuttle records an uncompressed file from a HV40, right? So you get virtually broadcast quality greenscreen plates and ultra HD footage.

    And, to get that footage into the Timeline of your NLE, I guess you just import it as a media file, instead of "capturing" it using the NLE's codec, is that right?

    That's a really dumb question, isn't it.....

    You only get the full quality if you capture live. Once your footage is on tape, you'll have the full HDV compression. You capture it into your timeline or into the file (basically the same). The cards use an NLE codec (ProRes e.g.).

    So if you record live straight to the Shuttle, (not on to tape), and then copied that file to your computer, then imported it into your NLE, you end up with HD footage compressed by the ProRes codec, right?

    The blurb says these recorders record fully uncompressed files...

    Is there a "major" difference in picture quality?

    The final result on screen might not be worth the cost, if it were just for straight non-effects filming.

    But I was thinking it would be a good way to get the best possible footage for chromakeying. Especially where there is some movement and/or fine detail like trees, hair, etc to deal with.

    So, is that right, then? If I record a greenscreen shot direct to the Shuttle on to an SSD card, then import that uncompressed footage into my NLE, and composite something in, I'll get a much better key than if the footage was compressed in the camera?? Surely.

    Obviously I'd be working with monstrous files while compositing, but if the shot was, say, 10 seconds long, that would be doable, wouldn't it?

    Yes, ProRes will help you to get better keys than HDV/AIC. However, I have seen no difference between AIC and ProRes422 yet. My keys are pretty simple though (I only shoot ponytailed women )
    There are meanwhile several ProRes tastes.

    Here's what I don't get, CG - the blurb for this thing says it records footage as an uncompressed file. In its own words, "HyperDeck Shuttle bypasses your camera’s compression and records from SDI and HDMI direct into the highest quality uncompressed video". No mention of using any codec at all.

    Obviously a codec will come into the workflow later on, after editing and sharing the video, (or saving it as am M2t file). But for the working footage, I'd like it totally untouched by any codec.

    Am I advertising my ignorance here?

    Some blockiness is can be seen in HDV coding, especially if you have to tweak a lot in post.

    If the Shuttle takes the HDMI 1920x1080 signal and records that at around 190 Mbps (≈ 1.5 GB per minute, 90 GB per hour), then there is no compression...

    Edit: That was just a quick calculation, it may be off by quite a bit; Apple says uncompressed 4:2:2 is 1,325 Mbps...

    Can't wait to receive Taky's T2i! But I'm still asking myself if it really worth it...(ML firmware)
    Someone wants to really convince me?

    I'm certainly not saying that you will never shoot with your hv30, but it will be few and far between if you have a t2i in your hand. Not to mention, there's so much beautiful glass out there. The old russian m-42 mount lenses, (many different brands) are gorgous, The ability to shoot in the dark is amazing.
    There are also issues, you need a shoulder rig (not always) but for narrative filmmaking you do, you need audio, the audio capture is fine for synching, and interview stuff, but thats about it.

    If they wern't all that their cracked up to be, guys like hurlbut wouldn't be using them for gigs, they really are cool little cams. You really have to look at it as another tool in your box. There's jobs I do with my A1 dof rig, and some I do with the dslr's. They both have advantages when in the right situation. I say get it.
    I'm feeling frisky!

    This is from the tech specs of the contraption:

    "SDI and HDMI switches between 270 Mb/s standard definition SDI and 1.5 Gb/s HD-SDI."

    The 500/550 use a mini-HDMI to HDMI cable, nothing special.

    OTOH, I once asked a salesperson to let me see video directly from my Sony Cybershot DSCWX5 camera on a Sony HDTV in the store - and he wasn't able to get it to work!

    If Sony can't interface its own camera to its own HDTV, there's something fishy going on... (No problems displaying it on my LG HDTV, though.)

    So, seriously now, those specs suggest that the Shuttle can record at the required rate to ensure no compression, right?

    If you have any questions about the product, even pre-purchase ones, Blackmagic Design will answer them. At least they were very responsive to my questions. Send them an email using their website, and I'm confident they'll respond and answer your questions. They will even respond to specific application questions. Like, "I have a t2i and want to connect the Shuttle to it for uncompressed recording. Will this work?"
