Hot pixels
In: Cameras
If you want to fix dead/hot pixels in your footage, you can do so in most NLEs.
First, make a duplicate track of your footage. Then, make a mask that is transparent, except for the dead/hot pixels. Attach that mask to the top video track, so that the hot/dead pixels are the only part top track that covers identical track below. Then, Gaussian blur the footage in the top track (but not the attached mask), so that the values/color from the adjacent pixels seep into the masked hot/dead pixels.

One way is to make a duplicate track of your footage, and, then, make a mask that is transparent, except for the dead/hot pixels. Attach that mask to the top video track. Then, Guassian blur the footage in the top track (that is attached to mask), so that the values/color from the adjacent pixels seep into the hot/dead pixels.
Here is a demo:

By the way, one good site to go to for documentary tips is http://doculink.org/ The Doculink "mailing list" is their forum.

Make transcription text files with time code references to all spoken lines in your footage/audio. Then, edit "on paper" before you even get close to sitting down at the edit bay. It makes the process exceedingly easier and much more thorough. You can add b-roll/cut-aways during the paper edit and/or during the NLE session.
If you have a lot of footage/audio (more than ~20-30 minutes), hire a cheap transcription service to make the text files with time code reference. The least expensive transcription services are probably in India and, perhaps, in the Philippines, and they can often transcribe most languages. These services are worth every penny you spend on them.

You beat me to it! I was also going to suggest a cheap base rig with rails with this one that has adjustable height on the camera platform.
Op, you might as well get a cheap rig such as this that additionally gives you rails to attach a matte box or lens hood, a follow focus, etc., if you ever want to use such items.
On the other hand, you could also just slide the camera to its most forward position on the Manfrotto 502.

There is nothing like lensrentals.com or borrowlenses.com where you are located?

Consider renting.
A $7000 budget for a camera package sans lenses seems rather excessive for a short. I've worked on shorts in which the budget for the entire project was a fraction of that of your camera (sans lenses) package.
Plus, renting gives you more flexibility/recover-ability. If you rent a camera that has a problem (such as fpn) or if you just don't like it, you can return it and get another camera.
Also, for a narrative short, you probably don't even need 4K, which could greatly reduce your budget.

Consider a fixture with some throw (not an LED panel), and a tall stand with a fill-able bag.
Unless you want to spend the money on a waterproof fixture, just learn how to deploy/use rain hats.

This is true. Rule of thumb is: 90% of c-mount lenses are designed for 2/3" image circles (i.e. half of MFT, equivalent to 4:3 16mm film), 15% are designed for 1/3" image circles (Super 8 equivalent) or smaller, 4% are designed for 1" (or Super 16), 1% is designed for MFT or bigger image circles.
Might want to check the math and add the percentages.
At any rate, there were tons of C-mount lenses made for larger videcons/plumbicons, so, not the above percentages are a "rule of thumb."

So yes or no?
How to check before buying a used one in the internet? Are there different C-Mount lenses with a different angle of view? If I understand it correctly, it will almost cover the sensor with 25mm and above?
There is no absolute image circle size for a C-mount, nor is there an absolute image circle size for the various focal lengths with a C-mount.
Furthermore, one can use an adapter to mount APS-C and full frame lenses to C-mount cameras.
You just have to determine the image circle of each lens on an individual basis.

tupp what problems were you having?
I was getting corrupt file headers, and, consequently, the files would not work on all players. Changing the microSD card fixed the problem.
Some have reported that removing or changing the SD card has fixed noise and crackling problems on Zoom recorders:

It has a soft continuous noise at about 1kHz and a ticking sound at about 2.5Hz.
Have you tried using a different microSD card? I was having problems with my H1 and a new microSD card fixed them.

It shows me that the f65's mechanical shutter is beautiful - but not really that noticeably better and definitely does not make the extra weight and bulk and size of the f65 worth it.
I think that the mechanical shutter makes a more noticeable difference with significant movement and with handheld shots. The mechanical shutter probably also reduces noise.
By the way, Panavision modified a few F65s by removing the mechanical shutter. They called the modified version the "F65 Mini," and they usually live in France:

Hey man, agree to disagree.....I know more about Al Green than even Al Green does!!! hahaha, seriously, my favourite singer, know all his tracks inside out. The pitch shift suited the video.
Okay, but keep in mind that such a treatment of a classic album cut screams "millennial discarding the sanctity of the original," and some in the position to hire might react adversely.
It's almost like using hip-hop jargon in business correspondence -- probably not a good idea.

Ah, quick release legs? Didn't notice at first.. nice
That feature has existed in other tripods for a long time.
I think that the Manfrotto 058B appeared at least 15 years ago:
I think Manfrotto has several models with this feature, including one with video legs. They also have a similar small version of this with separate release buttons at the top of each leg. To release all the legs at the same time, you just wrap your hand around the smaller base, and squeeze all the buttons.
I suspect that there are other manufacturers with tripods that have a similar feature.

Determine what your time is worth for each day, and add 10% for contingency. Add/list expenses, plus 10% contingency.
Hint: don't list the contingency amount separately -- just include it in the amount you list for your services and also in the amount for the expenses.
Have fun!

Well, there are a lot more costs in manufacturing than just the price of parts.
I included the manufacturing operations in the list. The design costs are essentially the same, as the only extra cost is creating another Autocad file and adding two to eight threaded holes -- the front tube to the EF lenses has to be designed, regardless.
On 8/12/2017 at 1:09 AM, mercer said:And there are plenty of modern super 35mm cine lenses that will mount to EF:
• Zeiss Compact Primes
• Schneider Cine Xenar III
• Cooke Mini S4
• Rokinon Cine
• Tokina Cinema
Again, your list is fine for those who don't want to stray outside of the box. However, creative pros will often want more versatility than that list (not to mention great Cine lenses which only come in PL.
On 8/12/2017 at 1:09 AM, mercer said:The EVA1 seems to be more of a B-Cam to a Varicam LT than an A-Cam to a GH5. I don't agree with that marketing/production decision but Panasonic seems to have designed it that way.
The short-sighted intentions of Panasonic's management/marketing/sales people have no bearing on what they should have done. Furthermore, outside speculation on some company's intentions is not exceptionally relevant.
On 8/12/2017 at 1:09 AM, mercer said:And not too many cinematographers are putting old Schneider Super 35mm glass on a Varicam LT.
Well, not too typical shooters are putting old Schneider cinema lenses on Alexas either, but they can if they want to!
I was helping someone on a commercial a few months ago, and the DP had just hit the big time. She is already sitting in on panel discussions with ASC and BSC members. She was using old Crystal Express lenses on an Alexa, and they were distinctively beautiful.
Shooters on that level usually seek alternatives to typical run-of-the-mill EF glass, as they are usually more sensitive to the subtleties of lenses' looks and effects.
On 8/12/2017 at 1:09 AM, mercer said:Unfortunately, Micro 4/3 is just not a professional cinema camera mount.
Then neither is an EF mount. However, cinema lens mounts don't need to be as rugged as PL or PV -- we have lens support for that.
Furthermore, Panasonic didn't have to commit to a M4/3 mount. They could have just made a shallow interchangeable lens plate, as I have described.
On 8/12/2017 at 1:09 AM, mercer said:And the EF mount offers enough possibilities for professional cinema lenses and for lower cost professional still lenses.
The EF mount offers only a small fraction of the possibilities available with a Micro 4/3 mount, an E-mount (there are ways to make this work) or an EF-M mount.
On 8/12/2017 at 1:09 AM, mercer said:But as far as adapting goes, there are plenty of older lenses that will adapt to EF:
For some PL mount lenses...
That is a risky adapter as there are plenty of lenses that won't into it.
On the other hand, a simple PL adapter for M4/3 will take almost every PL lens. In addition, some M4/3-to-PL adapters also allow TILT/SWING movement!:
Tilt/swing adapters are impossible with the EF mount and any full-frame or smaller lens.
On 8/12/2017 at 1:09 AM, mercer said:So you're right, there are some lenses that won't work
FTFY: There are countless lenses and adapters that won't work with an EF mount!
On 8/12/2017 at 1:09 AM, mercer said:but the EVA1 isn't designed for those lenses because not a lot pro cinematographers would use old c-mounts or Veydras or Speedboosters.
No. Regardless of speculation for whom the EVA1 is designed, a lot of the top cinematographers use PL/PV glass and also seek out all kinds of unusual optics and adapters (probably not Veydras) that will give them an edge.
Panasonic could have easily accommodated such high-end shooters (and even some of the lowly shooters who know better) while also catering to the typical EF people.
On 8/12/2017 at 1:09 AM, mercer said:I think you're more interested in the possibilities of a future AF200 and not an EVA1.
Actually, I think that every cinematography camera should have either a shallow mount or an interchangeable lens plate. We're experienced and creative pros -- we need versatility, not protection from FUD.

The problem is that at that price point, Panasonic wouldn't be getting anything out of doing it except extra engineering and manufacturing costs.
Actually, Panasonic would be getting a much more serious and versatile camera for very little extra in cost.
There has to be some sort of "tube" or enclosure going from the sensor to the lens mount. So, having that "tube" as a separate piece doesn't require much extra in materials, but it adds a whole heck of a lot to the capability (and maintenance) of the camera. The extra costs would be for:
- a separate die-cast piece (could be incorporated in the same die as the rest of the camera housing);
- one to four threading operations in the camera body (about US$2 each);
- a deburring operation;
- a powder coating (again, no extra materials here);
- wiring/contacts for the EF electronics (US$30?).
Such a small expense is negligible to such an expensive camera, but a removable front would greatly enhance what lenses and adapters/speedboosters one can use.
7 hours ago, mercer said:Most people buying at that price range won't be using Panasonic lenses anyway, so why incur those costs for a minority of shooters that want to use Minolta, Konica, or FD lenses?
Who said anything about using Panasonic lenses? That is the kind of narrow thinking that produces cinema cameras with EF mounts!
A removable front would literally open the camera up to a whole world of lenses, including professional cinematography lenses offered in PL mount, PV mount, C-mount, Arri Bayonet mount, and it would even allow the attachment of "Minolta, Konica, or FD lenses (which all have very nice optics)." Additionally, such a feature would enable the use of focal reducers (extra stops and wider view angle), tilt/swing adapters, macro bellows, helical mechanisms, and other lens modifiers.
Certainly, the typical walled-garden EF shooter is not interested in such versatility, but this multitude of possibilities would be very useful to cinematographers who want to create interesting images and who want to get an edge on the "straight" shooters.
Again, the additional manufacturing cost for a removable front would be minimal, and the EF shooters would never know the difference.

Isn't wavelet decompose in GIMP called frequency separation technique in Photoshop?
Yes. Essentially, frequency separation is wavelet decompression with with just two layers -- the residual layer and the high frequency layer. However, on Photoshop it probably still has to be done manually (similar to the manual procedure given by the OP).
Two layer frequency separation sets up a little more quickly in the GIMP, due to the grain extract and grain merge features. Of course, it is even faster to get two-layer frequency separation in the GIMP with either of the wavelet decompression plug-ins, but setting it up manually probably gives one more control over the "frequency."
I don't know if Photoshop currently has a wavelet decompression plug-in (it didn't have one four years ago). If it doesn't, manually making five wavelet scale layers plus a residual layer would probably be a long, arduous process in Photoshop.
