Introduction

This article is not the first I’ve written concerning my Moto Atrix. I’ve had this phone, as of the writing of this article for almost two years. It has been a great phone. One of the reasons I originally wanted this phone was the quality of the camera.

The phone automatically uploads camera files to my Dropbox account and so I can easily take videos and make comparisons using the ‘avconv -i videoname.ext’ format. Here are the results:

  1. Video 1 Characteristics (.m4v). The video is simply labled as “HD (30 m)”. I presume this stands for “hi-definition, 30 minutes maximum recording window”.

  2. Video 2 (.m4v). This setting is labeled “High (30m)”. Again, I’m presuming this stands for “high quality, 30 minutes maximum record time”.

  3. Video 3 (.3gp). This setting is labeled “Low (30m)”. I’m presuming this stands for “low quality, 30 minutes maximum record time”.

  4. Video 4 (.3gp). This setting is labeled “Low (MMS, 30s)”. Again, I’m presuming this stands for “low quality, 30 seconds maximum record time”.
    Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '2013-03-21 19.54.27.3gp':

  5. Video 5 (.m4v)
    This video is labeled as “YouTube (HD, 15m)”. This video has a 15 minute maximum and is high definition video intended for YouTube upload.

  6. Video 6 (.m4v). This video is labeled as “YouTube (High, 15m)”. This video has a 15 minute maximum and high-quality video intended for YouTube upload.

    Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '2013-03-21 19.54.59.m4v':
    Metadata:

Conclusion

These characteristic raise some pretty interesting questions. For instance:

  • Why is the framerate lower on the 1080 resolution images?
  • Why does the 720 video have a higher bitrate (higher fps?)?
  • Which is ultimately best to shoot in?

I guess each one has to decide for themselves although the high quality (not HD) will be where I’m headed when I go to use video on the Motorola Atrix 4G.
