Micro & Nano studio MOOC

Today we decided to create the ultimate mini studio for recording a MOOC with pro quality audio and video while on budget and in need of transportable setup.

The minimum we are looking for is recording the voice of our teacher a front camera and a tablette for his writing.

The Micro studio MOOC

The Micro Studio is a setup that will allow us to have 2 microphones like this two people could be recorded together.

Using the Atomos Ninja2 allows us to record the iPad Tablet

The tools we will use for the micro-studio are as follow:

  • 1x iPhone 5s
  • 1x iPad Pro 12.9”
  • 1x Apple pencil
  • 1x Apple HDMI adaptor (for our iPad)*
  • 1x Atomos Ninja 2
  • 1x SSD 256GB
  • 1 or 2 Lavalier microphone (XLR)
  • 1x iRig Pro Duo (for our iPhone)
  • 1x iRig Power Bridge

*Tips: you can use a power supply with the adaptor to charge the iPad. I would recommend to use the power supply of 29W for MacBookAir with an USB-C female connector and using the Lightning to USB-C cable from Apple. Doing this you will be able to recharge your iPadPro 12.9″ much faster than the original power supply provided by Apple.

Here is the schematic of our micro-studio

The Software we will use is as follow:

For the iPad

  • 1x PDF Expert
  • 1x FilMic Remote
  • 1x Clapperboard
  • (1x FileBrowser)

For iPhone

  • 1x Filmic Pro
  • (1x FileBrowser)

FileBrowser is optional, but is a great tool to transfer files from your iOS device to a Cloud server or a computer with sharing options using only WiFi.

The workflow

  1. We start the Atomos recording first then the iPhone is launched with FilMic Pro (with the remote option enabled)
  2. Now Using the iPad we will start (or stop) our recording on the iPhone using the FilMic Remote
  3. Both recorders are now recording (iPhone + Atomos)
  4. We need to synchronise them. We will use Clapperboard to do this
  5. On the iPad we launch Clapperboard and clap it
  6. The image of the clap will be recorded to the Atomos
  7. The sound of the the clap on the iPad will be audible through the speaker of the iPad and our microphone will catch this sound and it will be recorded on the iPhone. Because we connected the iPhone audio jack OUT to the Atomos audio jack IN using a Jack male-male 3.5 (this will work only for earlier versions of the iPhone than the iPhone 7) the sound will also be recorded on the Atomos Ninja
  8. Then we can finally launch PDF expert on the iPad and start our MOOC

PDF expert is nice because it will send the image of our PDF without the tools around it.

The Nano studio MOOC

For the Nano-Studio we will replace the iRig Pro Duo and iRig Power Bridge with the iRig Pro I/O. This is nice for a lighter studio but we will have only 1 microphone. On the other hand we will have the power supply for the iPhone directly provided through the iRig Pro I/O.

Nano studio MOOC

The tools we will use for the nano-studio are as follow:

  • 1x iPhone 5s
  • 1x iPad Pro 12.9”
  • 1x Apple pencil
  • 1x Apple HDMI adaptor (for our iPad)
  • 1x Atomos Ninja 2
  • 1x SSD 256GB
  • 1x Lavalier microphone (XLR)
  • 1x iRig Pro I/O (for our iPhone)

Here is the schematic of the nano-studio

The workflow will be the same as the micro-studio

Pro

  • very light studio
  • possibility to use it on battery only
  • good sound quality
  • good image quality
  • the iPhone using FilMic Pro will give a .mov container with an AVC codec and can also record the video in Pro Log (in version 6) giving some nice possibility for light and color correction in post production
  • The Atomos record directly in ProRes format allowing us to easily work with it in a post production software (Final Cut Pro X or Premiere).

Con

  • The Atomos Ninja 2 (and Ninja Blade) can record only 1080p 24,25 and 30 fps but the iPad using the HDMI adaptor can only send an image in 60 fps (59.94) therefore the resolution can not be recorded in 1080p and the Atomos will force the iPad to revert the resolution to only 720p 60fps (59.94).
  • If we wanted to record the Tablet in 1080p we would need to use a different, more expensive recorder. For exemple the Video Device PIX-E5 or PIX-E7 or Atomos Ninja Flame
  • For the moment PDF expert outputs the slides via the HDMI adaptor with a black border around it, and not in full screen 16:9. I hope for an upgrade in the future.
