Digibetas are generally used for capture and intermediate storage in the broadcasters I've worked for, for standard definition applications. HDCAM-SR for most HD, or DNxHD, as many more people are using EVS for studio capture/insert playback.

Pocket oscilloscope as waveform monitor
Daniel Smith replied to Phil Rhodes's topic in Accessories (Deprecated SubForum)
To be honest though at least it gives you a rough approximation of exposure, which is better than trusting a monitor with a 100x10^200 contrast ratio where even the sun looks correctly exposed. -
Apologies wasn't really thinking about portability.. Check out the 'Test Chest' or try Phabrix.

Could possibly find an SD-SDI Tektronix second hand for a reasonable price. Failing that, there's some Tektronix rasterizers around for an even more reasonable price that have VGA outs. It's just that BT.601/709 difference in down conversion I'd be wary of.

Nothing wrong with liking it at all, I can completely understand the artistic use of analogue mediums. It's just it sounded like you were totally obscuring your own argument beyond any logical sense to prove analogue formats were factually better, something I wouldn't have a problem with if you could back it up.

Building a Lighting Kit...
Daniel Smith replied to Victor Bareno's topic in Lighting for Film & Video
On that note, if anybody's interested it's definitely worth looking up ingress protection: http://en.wikipedia.org/wiki/IP_Code Most 16a cee-forms are IP44, but you sometimes see IP67. Was quite a challenge during the Oxford vs Cambridge boat race trying to keep everything safe. Fortunately the yellow cee-forms are designed with a slightly different 'key' shape and won't connect with blue cee-forms, even though they look the same (the notch that normally indicates up or down is rotated around 180 degrees.) -
Black-Magic Design Announces 2.5k Cinema Camera
Daniel Smith replied to Tim Tyler's topic in BlackMagic Design
Sorry, this was too good not to share -
It's often the small but key things that get overlooked. A beautifully shot film - graded by the director on a £150 TFT. An amazing drama - no sound-post, let alone ADR. Or better yet, ADR with no-alignment. I'm hardly one to talk but generally the better productions I've worked on have normally been where the guys in charge have had both technical and creative competence. I think my biggest grief is still the way people think it's acceptable to grade 4th generation dubs and expect to pull HDR results out of it. I don't know of any official details from SMPTE surrounding 6G-SDI but please let it not accept any form of interlacing, at all, whatsoever. (Please excuse the tangent.)

Converting XLR 5-pin to 4-pin
Daniel Smith replied to Jerry Mao's topic in Accessories (Deprecated SubForum)
As long as you're sure whatever's coming down the 4-pin XLR is rated respectively it shouldn't be an issue. Buzz the cores out and test for positive polarity with a multimeter before plugging it in, better safe than sorry with power. -
I can understand keeping the original negative, when scanning methods improve there may be value in re-scanning the original negatives and restoring them, as in the case of the 'Jaws' video posted in this thread. However to scan the film, re-edit/touch and then burn back to film, and then re-scan, it's the difference information I'd be interested to see before and after this process. Is any quality lost during the transfer to film and back/is the film format able to retain picture detail with the same strict quantisation levels found in digital. I'm not referring to quantisation in the sense that film has binary values, but in the sense of, is the format able to retain picture detail to a finer accuracy than say for instance, a 14-bit scanning system, how much does it drift, how linear in nature is the loss (if any.) Like I said, I'm not saying film does drift or isn't accurate enough, but I'd still be interested in seeing test results before and after.

I'd still be interested in viewing difference mattes between film before archival and after re-scan. No one stores high value content on one LTO tape, nor one hard disk, so making comparisons between one LTO tape or one hard disk VS a roll of film isn't a practical comparison. Data redundancy by today's standards makes digital archival achievable theoretically for as long as we want it to. What attracts me at least to digital archival over film is having the confidence that I'll get back exactly what I put in. Which is why I'd be interested in seeing PQA results between pre-archived material stored on film and then after archival and re-scan. You could probably argue that if quality was lost it was due to the re-scan not the negative, an optical to digital process I would assume will improve in years to come (a process improving faster than the deterioration of the negative.) Admittedly I have very little experience with film, but I remain unsure about its ability to retain picture detail within such discrete quantisation levels found in digital systems, for instance 14-bit scanners - from archival through till re-scan.

I doubt this will be worth it because of the postage costs but I always shop bryant-unlimited.co.uk. I've always got a good deal there.

I can see the value in that film is able to retain the quality of its pictures for many years, in comparison to hard drives for instance in which from my experience last around 5 years (normally because of mechanical failure - but not that SSD's are much better.) I think you're right in that it's more worthwhile for material with high economic life, I think the process of transferring to film and back isn't as flexible as accessing data held on a RAID array, although in the context of archival I don't think flexibility is necessarily an important factor, and when you're Twentieth Century Fox dealing with the original prints from 'Star Wars', I don't think the cost of doing so is an issue.
-
I think what would put most people off archiving onto film nowadays is having or paying for the facilities to transfer the content to film and back again, along with physical storage space, demanding storage conditions, along with the time it takes and any loss of quality over time and/or through transferring content to the optical domain and back. Let alone the fear that manufacturers may not support the technology in 20 years time (ie. Try getting spare parts.)

The Sennheiser ME66 isn't bad for its money, I've had many good experiences with it.

Breaking into films
Daniel Smith replied to James E Wright's topic in Students, New Filmmakers, Film Schools and Programs
I'm studying a BSc in broadcast engineering and when I posed interest in a telecommunications position in the Navy I was told all broadcast engineers did was change light bulbs on a stage. I think it's fair to say subjects surrounding television and film are not always as academic as pure STEM courses, but they have their own unique challenges, of which anyone without any experience in either industry are often ignorant towards. -
How do I color correct to look like this
Daniel Smith replied to Elliot DeBonee's topic in Post Production
Many professionals use grade 1 monitoring, which is far too expensive for most people to afford independently. The environment you are grading in is also important to consider, if the room is painted sky blue, it may affect your eyes overall perception of colour thus affecting the outcome of your grade. Lighting is also important, try and work in a dimly lit room where your perception won't vary as a result of surrounding light. Normally grades consist of a technical grade followed by more of an artistic grade. The technical grade often entails exposure, black level and colour matching alterations, whereas the artistic grade is more about making things look pretty (ie. lowering the detail to create a silky effect, like the one you referred to.) The real problem with grading is that our eyes are constantly grading themselves, thus altering our perception and ability to grade images impartially. Check out effects like bilateral blur in After Effects. -
How do I color correct to look like this
Daniel Smith replied to Elliot DeBonee's topic in Post Production
Looks like the hues of the blues in the sky could change to produce more of a purplish/magenta tone, adding reds only to the blue component. The relatively low contrast helps. I'd try lowering the detail/clarity levels to give the image a pearly effect. -
But what if someone's financial circumstances changed throughout the duration of the course? It may be that the institution did not fully inform her of the financial requirements of the course to begin with. It would be unfair to fail someone on either basis. The only lesson I think she would be taught if the school were to fail her is that film is for rich people, which I'm sure neither of us would believe.

I think you could probably achieve the prolonged shutter speeds in the time-lapse automation software I mentioned. You can set all of the parameters up in the software and let it roll. The real question is will the software communicate with your camera, or can you get hold of a camera that will. I wouldn't attempt forging it though, it's not worth the risk. I think any tutor would or at least should understand if you don't have the money for the film, nor should you be obliged to sell what you have. I think it would be elitist of the school to only accept work shot on film but not provide the materials or equipment to do so. I can't emphasise the importance of talking to your tutor, they are there to help with problems like these, not to penalise you because you're not financially in a position to purchase the required materials. Andy made a good point about looking for some kind of sponsorship, it's amazing how much companies are willing to help at times, it's worth looking into.

I'm not very familiar with that model of camera, but there is software available allowing you to connect a laptop to an SLR (at least) and set it up to take pictures at predetermined intervals. A lot of people use it to produce time-lapse videos, which looks a bit like what is going in the video you posted. As a fellow student, I'd suggest talking to your tutor so they are aware of the difficulties you are having, and if you do shoot digital, grade it and add effects to make it look more like film but be ready to justify every alteration you have made either in your presentation or report (or whatever is required at the end of the project - if anything) Turn the negatives into positives.
