I am not an editor nor a post person, but one thing that I always hear from pro editors is that they never edit with a compressed, capture format. By transcoding all of one's footage to an uncompressed edit-friendly format, computer resources are saved for effects, filters and rendering, etc., instead of continually decompressing a resource-hungry camera format on the timeline.

I have been using the BMPCC the last two years.. But seems to be the RAW 3:1 dng files that are not possible to view except with Resolve. My OS is El Capitán...
If you can view the files in Resolve within the OS in question, then it is not the OS.
Can you post a link to one of both 1:1 and 3:1 dngs?

Guys i have the problem that Mac OS doesnt recognize the dng files of the BMMCC, so the only way to see the files is with Resolve.. They appear black on Mac OS. Not even Photoshop or After Effects can open them.. Is anybody else having these issue?
It is probably not the fault of your OS nor of your image manipulation programs. Keep in mind that dng footage is essentially a bunch of raw still photo files (one for each frame of footage) consecutively named and located within a directory/folder. So, trying to view the folder might not work in Photoshop. However, you should be able to view an individual dng file as a raw still photo.

Don't over-think this job. You are not shooting "Lawrence Of Arabia." On the other hand there are a few things to consider in regards to how trade shows work and on how to optimize the video coverage for your client.
First of all, do not contact to the trade show management directly about anything. As an exhibitor, your client is a paying customer of the expo, and he is the one who should deal directly with the show management on all matters. You are not with the independent "press" -- you are hired by an exhibitor, and he will probably get you an exhibitor's badge. I have been to a few trade shows, and I have never heard of trade show management prohibiting an exhibitor from shooting his/her own booth. So, unless this expo is the "Anti-Paparazzi Con" or the "Paranoid, Secretive Espionage Agencies Con," don't sweat the lack of official permission to shoot.
Secondly, your idea of shooting a time lapse of the booth set-up is nice, but keep in mind when choosing your camera position that things move around a lot and unexpectedly appear and disappear during a trade show set-up: fork lifts; man lifts; push carts; carpet (will eventually cover any bare concrete that you see); signs (erected from the floor and hung from the ceiling); and, of course, big, opaque booth walls will appear. You might have to move your camera out of the way at some point.
It is probably wise to shoot some live coverage in your client's booth during set-up, but most of that footage will probably be dull, so there likely is no need to spend the entire day shooting set-up.
The first day/morning of a trade show is usually the most active and exciting. Your client will probably want some shots of his booth full of attendees. So, be ready to shoot at the start of the first day. Don't get too big with your rigs -- be nimble so you don't miss anything. A camera with a zoom lens and a monopod are probably all that you need, perhaps along with a shotgun mic plugged into your separate recorder (the camera sound will grab anything off-camera). Look for interesting/positive interactions.
Be mindful that the last day is usually the slowest (that morning might be good for sit-down interviews) and that, at tear down, most exhibitors want to pack up and go home.

Don't know if the forum has ever discussed this Feelworld viewfinder (US$229) or this Feelworld monitor (US$139). Both of these items are spec'd to handle a 1080P, 60fps/59.94fps signal through HDMI, so they might work with the BMMCC's 60P output.

I appreciate the gratitude, but thanks/credit for the "hood>filter" stacking order should go to aldolega.

Did you try trimming the rubber lens hoods back with scissors (or an Exacto knife)?

That's a "French flag." I prefer a cheap matte box to French flags.

Fold the hood back when you need to adjust the filter.
Sounds like a good plan! (Just don't want get the filters too far out in front of the lens.)

Does that filter have 77mm female threads on the front? If so, here are some options.

Was going to go with the 478, but thanks to you will be getting the Kenko.
I am glad to be helpful. Please note that I have never used the meters that I linked.
By the way, when you start using your incident light meter, it is generally best to aim the meter's dome directly at the light source (as opposed to aiming the dome at the camera). This is true both for taking lighting ratios and for getting exposure readings. Use your free hand to block light from other sources (including reflectors) that you do not want to meter. By aiming the meter at the directly at the light source, one avoids blowing out the highlights with that particular source, regardless of whether or not it is positioned to the side of the subject or more frontal to the subject.
Aiming the dome at the camera can give a useful additive/average exposure reading in situations in which you have more than one frontal light source with a lot of overlapping coverage on the subject.
-
Incident light meters are great for learning and for recording lighting ratios. Recording lighting ratios is especially valuable in case you ever have to reshoot a scene or duplicate part of a scene at another location.
Spot meters are not very helpful in this regard, as the subject's orientation and/or surface characteristics can dramatically change the reflective exposure reading, even though the incident lighting remains the same.
Any digital incident meter with a fineness of 1/10 stop increments is more than enough for any lighting ratio needs. I have about five meters, but the one I use most is the discontinued Minolta Flashmeter IV. Kenko currently makes a knockoff of the Minolta Flashmeter V for US$249, which seems to have decent reviews.
The Sekonic L-308S is US$161 on Amazon, and it has 1/10 stop increments. There is a more recent model of this meter -- the Sekonic L-308S-U -- priced at US$199.

Oh god, frankenstein camera.
That's like calling the Model T a "Frankenstein" car.
Because some of us have only seen products created with the more recent advancements in miniaturization and integration, some might sneer at venerable products such as the Graflex large format SLRs as unwieldy, "Frankenstein" rigs. However, that 5x7" SLR was a sleek, modern, integrated, state-of-the-art camera back in the early 20th century. Here are pages from a 1923 Graflex catalog describing some of the special features of their large format SLR line.
Actually, it is difficult to imagine how to make a 5x7" SLR much smaller, even with today's manufacturing advancements. Might be able to make it lighter and stronger, but Graflex cameras certainly were solidly built
And how cool would it be to attach one of the Large Sense backs to such a large format SLR?!

- The largest and/or smallest Rifa (lamped w/tungsten) w/egg crate;
- 2 600w squeezers;
- 2 25' stingers;

- 1/2 CTB for all lights;
- 1/2 CTO for the Omni and Pro lights;
- Various party gel and diff;
- Other non-gel expendables -- black wrap, gaff tape, bullets, bailing wire, etc.;
- Various portable grip items -- Tota-clamp, Tota-tatch (mini trombone), #1 grip clip w/baby pin, #2 grip clip w/baby pin, fold-able flag/silk w/swivel clamp, french flag, etc,;
- spare bulbs.

What about large format video? http://largesense.com/
Great find! Holy cow!!
Gonzalo Ezcurra's E/Mini Cyclops cameras have a larger "sensor" than these Large Sense cameras, but 50micron-70micron pixels covering large format frames?!!!
How did this guy make/find the sensors? The rolling shutter is not bad at all. I am guessing that these backs will cost a little if/when they go into production, but with the right price these things could move.
Very exciting!

Interesting. What kind of continuous shooting times are you talking about?
Like I mentioned, I've run up to about 2-hours of continuous recording and not noticed any difference, and the lens-cap test always shows you what you've got noise wise.We had a new, zillion-take take director, so we had the camera on for two to three hours in some scenes, sometimes going through two XTPower batteries in a half day.
When the BMPCC got warm, more continuous hot pixels appeared.

The BMPCC is DESIGNED to run on an external power source of 12-18v.
Any batteries will supply less voltage as they run down so using the 9v setting on the XT Power can cause an UNDERsupply situation that can cause internal operational problems.I know that the BMPCC is designed to take 12-18v, but it works with lower voltage. Except for the fact that the internal battery doesn't charge with an external power supply, I never had any problems using the 9v setting on the XTPower with the BMPCC.
21 minutes ago, DPStewart said:The BMPCC has an internal DC-to-DC regulator that wants 12-18v coming into it. That regulator is going to send the correct amount of current to that various internal systems. Using the 12v setting or even the 9v setting on the XT Power is not going to cause an overheat condition in this camera.
That 12v power supply that comes with the camera? The engineers designed the camera to run off of that.I'd rather use an external voltage regulator than heat up the internal voltage regulator and nearby camera sensor.
26 minutes ago, DPStewart said:I have run BMPCC's for over 2 straight hours of recording on both internal and external batteries (switching out the internals as fast as possible) and I have not ever noticed any housing temperature differences over all 3 of my BMPCC's.
Simple test: Keep the lens cap ON and run the BMPCC in record for one hour each using both internal and external batteries.
I saw no difference in noise.I shot a feature using two BMPCCs, and, fearful of under-voltage and wanting to keep the internal batteries topped-off, I always used 12v for external power. About 2/3 of the way through the show, I accidentally ran one BMPCC with the 9v setting on an XTPower, and it worked flawlessly with less heat and noise. Wish I had had that accident earlier in the production.
30 minutes ago, DPStewart said:The SONY cameras like the A7s described in that video may be an entirely different design that does indeed require a lower input voltage.
Well, it is a good idea to always run a camera at the lowest necessary voltage, for avoiding heat and for other reasons.

Coincidentally, I hold an Extra Class ham radio license, and I was a drummer in many bands for longer than I care to admit.

This is a bunch of basic information about affordable camera support gear.
Great video! Very informative, and it is further helpful that you demonstrated that some of the gear is booger-proof!
For my personal gear, I tend to go for much cheaper and lighter solutions, such as those shown on the Frugal Filmmaker channel.
The XTPower batteries are great. I have 3 of them as well. On the other hand, I sort of wish that I had instead purchased less expensive Sony NPF clone batteries, as they run at most cameras' (including the BMPCC) operating voltage of around 7.2v-7.5v. The 12v setting on the XTPower units is nice if you want to charge the internal battery on the BMPCC while you are shooting, but such higher voltages heat up the camera and sensor more than necessary, and, thus, produce more noise. The 9v setting on the XTPowers reduces the heat/noise, however, here is a video on how to easily use a cheap voltage converter to get 7.4v from 9v-12v batteries.

Their existing lens range wont cover an s35 sensor though.
With the JVC tech (and with Canon sensor cropping), the lens doesn't need to cover the S35 sensor.
Furthermore, a lot of pros don't care about using any particular line of line of lenses, they just want versatility -- a shallow lens mount that will allow the mounting of any lens.
Really, the concept is super simple. Just give us the shallowest lens mount possible and let us pros worry about "coverage."

Okay. Attached are the five versions of TL that I have for the EOSM. I think that the only difference between them is the "autoexec.bin" file.
Enjoy!

Really there were only ever TWO hacked Camera OS's - Canon by Magic Lantern and GH2 by Vitaliy
Additionally, there was nikonhacker.com, pentax-hack.info, nex-hack .com (Sony cameras), and, evidently there is a GoPro hack from CHDK.
By the way, the main Magic Lantern developer (A1ex) was originally a contributor to the CHDK project prior to starting ML. CHDK is still very active, primarily providing extra still photo features to Canon cameras.
Of course, there is also the Tragic Lantern fork of ML (which is still used to get All-I frames from the EOSM and the T3i/600D), and the is the existing Samsung NX hack.
