Introduction

Tarina UI

Tarina UI

The interface focuses on presenting the essential tools in film making in one menu that is present and accessible all the time. You can control it with a keyboard or with the physical buttons; Enter, Up, Down, Left, Right, Record, Retake, View and Remove.

Retake function

After recording a take you'll see an image of the last frame of that take. Now, if you hit record again you'll move to the next shot in your movie. If you press retake you'll move to a new take of the same shot in your movie. Now, the live view is back and next time you'll hit record it will actually start recording. So, if you're browsing shots and a frame is present instead of the live view, hitting record will take you to the next new shot in your movie. Makes perfectly sense, right? When live view is present it will always start recording. So record and retake are multi functional buttons in that sense. Fiddle around with it, you'll totally get it and be blown away how simple it is.

Buttons

With keys up and down you change a specific setting, for example shutter speed. With keys left and right you change what settings to change. With view, you can view the last shot or if you have a specific scene highlighted the camera would automatically glue all shots together and play that scene for you, same goes for film. With remove you can remove a specific take, shot, scene or film. With the retake button you retake a bad take, this is how the camera keeps track of your good takes. The last take is always the chosen one.

Special keys on the keyboard (CAPITAL):

Y = Copy scene/shot

M = Cut (as in cut and paste) scene/shot

P = Paste scene/shot

I = Insert empty scene/shot

space / pgup = Rec / Stop

pgdwn / backspace = Retake

tab = view

Menus

A short explanation of all the settings and why they are where they are.

Film, scene, shot and take

This you don't see on other cameras because they don't care about what you're filming, however this camera does and it wants to know where you are in your filmmaking process and help put it together. Of course this means that you have to know where you are in your filmmaking process. The idea of the workflow is: film only the essentials, check your montage on the spot and do a retake if you need to fix something rather than filming a bunch of things and fixing it later on another device. This will save you alot of time.

Dubbing

If you press enter while you've highlighted the film name or a scene you'll be entering dub settings menu. (ADD:d:1.0/o:1.0) this indicates the volume of the (d)ub to the previous (o)riginal mix. So, for example if you want the dub volume to be 50% of the previous audio, the settings would look like this (ADD:d:0.5/o:1.0). A good all-around background music volume level is only 10% so it would look like this (ADD:d:0.1/o:1.0). The other setting is fade in and out in seconds (in: 0.5) (out: 1.0) whould be half a second in and a second out. Now if you press enter while the ADD is highlighted you'll be dubbing. You can change the settings later if you come back to the menu. You can add up to 99 tracks!

Shutter, iso, red, blue

Shutter and iso are well know basic camera concepts. With red and blue you control the colors. If you press enter while on any of these then it will go into auto mode and if you press it again it will go back to manual mode with the current auto settings. I'm using this feature to quickly find a reasonable good value before I'm locking and tuning the settings manually to my likings. Cuz you always will know better than the robots!

Bright, cont, sat

Color grade on the go with brightness, contrast and saturation. You will probably have to play with theses to figure out what you want. Remember that as you're making your film ready while you're shooting it take by take, there's no color grading later on so you'll have to settle on your color grade before you film. To get that good old spaghetti western look go with the contrast at -19.

Flip, beep, lenght

If you go gonzo, flippin it is the way to go! beep is a countdown timer from the moment you press rec or retake to when it actually starts filming. Lenght let's you put in the lenght of your take before you actually start filming. Both of these are very useful if you film action alone and can't reach for the buttons.

Mic, phones, comp

Control teh level of your mic and headphones. Comp is a basic compressor so your message comes across and we hear ya! it's quite harsh at the moment but I like it when it goes craking up abit like in the good old 70s cinema.

Timelapse

Do a timelapse when you need to tell about time. There's an under menu here where you can choose the intervall of the takes, now this isn't really a traditional timelapse, it will instead do a 0.2 sec video at each intervall or it can be set to your likings but 0.2 is good for a traditional timelapse effect. At the bottom of the screen is a calculation of how long the clip will be if you do the timelapse for an hour. I'd say don't over do it! a 10 - 20 sec clip is already quite a stretch but its up to you, you're the movie film director.

Lens

A future implementation of lens shade correction will come where you get to do your own lens corrections to get those colors right on the spot!

Dsk, shutdown, srv, wifi

Disk space, showing you how much of space left on your sd card. Shutdown, when your really done! it's good to do this before cutting the power or otherwise there's a small chance of sd card corruption. Srv is a network server, if your connected to a network and put this on you should be able to go to any browser on any device and watch your movie films (that is if you've rendered them first), just go to http://tarina.local or it might be that you have to know the ip address of your tarina (you'll find it when you've connected it. Press enter on wifi. There it is on the bottom of the screen, looks like this 192.168.1.105). If you press enter on wifi you will be transported to a glorious program called Wicd curses, here you really need to have a keyboard to set up your connections. Hints are down on the screen what buttons to press. To get back into Tarina press "q".

Update and upload

Update the camera to the most exclusive version, this is still pretty much a-work-in-progress and as a warnign expect some bugs! don't worry I'll be improving things but it takes time. Upload your film to the web, there is a youtube uploader mod you can install but you'll have to do some configs to make it work for you. Details coming soon. Reach out to the matrix room if you're in a hurry..

Backup

It's good to always backup your stuff! Plug in your usb drive and just press enter and sit back and relax as the wonderful work of computer copying does the magic. While you're at it open a beer cuz it can take quite a while if you got much stuff on there. Now, this should be working on almost all hard drives but there are some that still use a very old file system called fat, and its as lazy as its given name and doesnt store critical information we would want, because we want the copying to only copy our new takes or retakes. So please use new drives like ntfs systems or ext or whatever they all are called. You'll find all your takes even the shitty ones on your harddrive in a directory called /tarinafilms/. One more thing, there are some drives that are very power hungry and doesnt come with it's own power source, now these drives are very bad for this particular use because the Tarina has limited amounts of power for usb use, so to be sure it's gonna work, use powered hard drives that has got a power cord.

Load and new

You can have many on going films, load em up or start as many films as you like.

Tarina parts layed out

Tarina parts layed out

Here is a list of parts that will work, there are other parts that probably will work but requires some hacking.

Raspberry pi 3 B

Price ~30 eur

The heart of Tarina. Why Raspberry pi you ask? There are several reasons:

The 3B+ is too powerhungry for the Powerbooster 1000C thats why I went with 3B

Links Raspberry pi site Buy Aliexpress

Arducam 5 MP OV5647 camera module with CS lens

Price ~30 eur

This module and lens gives good hd video quality with the ability to manually focus and replace lenses. See tested lenses down below.

Links Arducam Buy ebay

Ugeek 3.5 inch 800x480 TFT Screen

Price ~35 eur

Best 3.5 inch screen that I could find. Features worth mentioning:

This is not a touchscreen but I dont think touchscreens are good for cameras anyway.

Links Raspberrypiwiki Buy Aliexpress

USB via vt1620a sound card

Price ~1 eur

Really cheap usb soundcard. It has been working suprisingly well. Have not tested other cards yet.

Buy Aliexpress

3.7v 7800mAh li-ion Battery

Price ~17 eur

I have tried several batteries, the adafruit 6800mAh is also fine.

Buy Aliexpress

Adafruit Powerboost 1000C

3d printing

While waiting for ordered parts lets 3d print the rest of the parts. I recommend printing with a solid 90% infill. Now it is pretty crucial that you have a good calibrated printer so that you don't over/under print. Some parts need to be very precise to work.

You'll find all the 3d parts in the 3d folder.

Post processing

This is still a work in progress...

So far I've come to this conclusion:

Wiring
