Mobius Q & A - Questions and Answers
140520
Q. Recorded at 720p and 60FPS, can the file be played back slow motion at 0.5 speed (30 FPS)?
A. Yes and No.   The MOV contains 60 frames per second and parameters in the file specify 60FPS playback. So, the file will normally playback at 60FPS (1X speed video and audio). 
However, some players can play back slow or fast. 
VLC & WINDOWS MEDIA PLAYER - will playback at various speeds so at 0.5X the video will play at 0.5X speed (30fps) slow motion and the audio will also be at 0.5X speed but the frequency is corrected (not one octave lower). 
KMPLAYER  - can playback at 0.5X but on my computer the video is not smooth (jerky), it starts and stops while playing.
HANDBRAKE - if the file is re-encoded to MP4 30FPS, Handbrake discards every other original frame so the resultant video and audio plays at 1X speed, probably not what you wanted.

Mobius Objective Data
All metrics are subject to change
Video and Photos - No up-scaling.  No aspect ratio distortion when files are displayed with square pixels.

Video File Path, example - DCIM\100HDDVR\REC_0001.MOV

1080p 
Summary -
1920x1080, 30 FPS, MOV format.  Horizontal angle of view is about 87 degrees (wide angle).  File data rate is about 120 MB per minute.  The audio is 512 Kbps PCM sampled at 32kHz.  It seems that key-frames are every 15 frames because "SolveigMM Video Splitter" will cut only on 15 frame boundaries.
Info from KMPlayer for a short outdoor-light clip:

AOV
- The Angle Of View measured empirically.  I used this method: I set a long tape measure on the ground and took images at a distance of 34 inches.  I used the math on this page to calculate the AOV.  For reference, a 50mm lens for 35mm film has a horizontal angle of view of about 40 degrees.

Removed
This information was removed either because it applies to older pre-release firmware, or it is not correct.

Removed because this method of AOV measurement does not work for a fisheye lens.
AOV - The angle of view measured empirically, using this method.  At 36", a landscape 11"x8.5" sheet of paper is about 464 pixels wide, in both 720p video mode and 2048x1536 photo mode.  This might mean that 720p uses the cropped center of the image sensor.  I don't understand why the photo mode has the greatest horizontal pixel count, but 1080p video mode has the widest AOV. Needs an explanation.
