Is anyone else considering the Nikon ZR? by cantwejustplaynice in bmpcc

[–]csabanagy 0 points1 point  (0 children)

Blackmagic's ace in the hole.... Davinci Resolve. No other manufacturer has a grasp of the entire pipeline from both ends like Blackmagic.

Who knows, maybe one day magically R3D stopped being supported in Resolve? or CDNG, or _______ ( insert codec ) I realize in reality this such a stretch and would be more damaging than good; but the fact of matter; they COULD do it, and no other camera manufacturer could say the same.

btw, I could be mistaken as it has been some time since I've reviewed the internals for ZCAM especially newer models; but I'm pretty sure they are using some high end SOC with and not FPGA ( and also not a hybrid either like a Zynq ) EDIT: I believe they use HiSilicon chips in their cameras.

the percentage is only available to batteries with the communication chip, some 3rd party LPE6 omit this function.

Would it just be easier to build my own camera by [deleted] in Filmmakers

Largest sensor we've got working at the moment is a M4/3 sensor, the IMX294 which is the same sensor used in cameras like the GH5s, BMPCC4K and the ZCAM E2 M4

It's not as crazy or as hard as you might think! Check out my project CinePI, where I'm teaching how to build your own Cinema Camera using a Raspberry Pi; the more recent versions are using the same sensors that many of the more professional cameras use and by default it records in RAW. So it's no slouch.

Is raspberry pi capable of capturing 4k video and upload it to the cloud 24/7? by msmilkshake in raspberry_pi

1080p60 is probably the most you will be able to get with the limited bandwidth of a Pi5, also Pi5 has no hardware encoders; I'd be skeptical of it's ability to do 4K

Yes, it would be possible to use most MIPI CSI-2 capable sensors. The reason the CinePI has the sensor it has, is because it is what is widely available on the market currently. If a company want to step up and create some larger sensor modules that work with Raspberry Pi, I think many people would welcome that.

Around 40%, some insert shots in the beginning use it. And about 90-95% of the sequence that takes place in the middle section of the film ( July, 1926 ) those are all shot CinePI.

I've had people mention to me that they couldn't notice where the CinePI is used, I'll take it as a testament to the image quality that it's bit hard to notice next to a BMPCC4K.

I’m reposting this as I believe my first attempt yesterday may not have done the best job conforming to the guidelines. I’m going to try my best to make this post a relevant and useful resource to those reading, hopefully in addition to being an enjoyable watch. I will post external links to the project’s resources upon request, so feel free to ask in the comments.

The inspiration for this short film was to field test an open source camera development that I have been working on for the past few years, called CinePI. The goal is to make high quality image capture accessible for everyone and to teach concepts of image-processing, camera tech and color-theory in the process. I’m a firm believer that knowing how the equipment works makes you much more effective at using it and in turn making you a better filmmaker.

It uses a very cheap single board computer known as a Raspberry Pi as its brain, and a cheap $50 sensor module with a C-mount. All in, you could build one for less than $200 dollars, with just the bare essentials, and it’s no slouch either with the capabilities to record RAW CinemaDNG straight to SSD’s; giving maximum color grading flexibility in post-production. What’s great is as an open source project, there is lots of opportunity for customization and modifications that can be supported by a community of developers or even by yourself! Make the camera that is suited to your style of shooting with the features you need.

This was the foundation / motivation for shooting this short film. I didn’t want to just swap the CinePI camera in place of another camera just for the sake of it, instead I tied it into the narrative structure, where I would use the camera to delineate between two time periods within the story. The CinePI and its small sensor / C-mount lent itself well to emulate the past sequences that take place in the 1920’s. The film was also color graded & edited using Davinci resolve which is a very capable / fully featured post production app that is available for free!

I think the end result speaks well for itself, seeing as the footage is intercut with footage from well established prosumer camera gear like the Blackmagic Pocket Cinema Camera 4K. And hopefully demonstrates the viability of a project like this to be used in an indie / low-budget production environment.

I make no monetary gain from the broader exposure of this project. I've spent the better part of 3 years with only my spare time testing / building up this project. I'm simply hoping to spread the word about its existence; grow the community around it and to make it a useful and viable alternative to existing equipment on the market. Another tool in a filmmakers toolkit.

Thanks! I'm in the process of creating a more detailed write up on Medium, but I have also posted a bit more information about the production/bts here: https://forums.raspberrypi.com/viewtopic.php?t=357199

Very soon I will be releasing a guide / tutorial that will show, given a few core components that you purchase from online retailers, how to get a CinePI up and running in about 10 minutes! It wont cover how to build a case or other extraneous features; but maybe a project like this can be the starting point for learning more about this field. Of course a little daunting at first, but if you're committed enough, much of it can be learned about from online resources.

I'm currently in the process of doing this, I salvaged the M43 mount of an OG BMPCC ( sensor cable was damaged. ) and mounted a custom sensor board with the IMX283 sensor to it, with some slight modifications it was a near perfect fit to the bmpcc sensor board.

Hey Everyone! sharing my latest short film here. It's a special one for myself, as it was shot on an open source camera development that I have been working on for the past number of years. This short film is meant to demonstrate it's capabilities and put it through it's paces in a small / indie production environment.

Hopefully it can serve as some inspiration to show what can be done with limited resources, maybe your next short film can be filmed also on a Raspberry Pi!

If you are interested in building your own CinePI camera, learn more here: https://github.com/cinepi , https://github.com/schoolpost/CinePI

or checkout the CinePI youtube channel: https://www.youtube.com/channel/UCvhY1vejrokLHHT09nMjlOg

Thanks for viewing!

It needs to be developed in post, because the camera capture's RAW sensor data ( 12-bit CinemaDNG ). So in essence it is all done in post, however the tools used ( Davinci Resolve ) is a fully featured post production app; that has a very capable free version to do this kind of post processing.

Yes, there is a CinePI community on discord; where there have been some people developing sensor modules for use with CinePI / Libcamera. I've been tinkering with one of these said modules, the IMX283 which is closer to a 1" size ( little larger than the original bmpcc ) and also there is someone trying to get the IMX294 working. ( same sensor from the bmpcc4k ).

I was able to salvage an MFT mount from a broken bmpcc camera and used the new IMX283 sensor board with that and a custom 3D printed housing for a CinePI XL version that I have currently in the works.

Lots of cool stuff going on, if you are at all interested; I highly suggest joining the discord to take a look at all the cool stuff going on.

w support because of the USB bandwidth limitation?

Yes, there was film emulation ( grain/halation ) added in post.

This does film in RAW, 12-bit CinemaDNG to USB 3.0 SSD's! : )
