Nano Flash Workflow Guide

Nano Flash is now a very popular tapeless recording addition for any camera with an HD-SDI out. The reason for it becoming so popular is that it can record a number of different formats which broadcasters approve of (basically anything that can record a 50Mbit + data stream). It’s a great way for production companies to get more value from cameras that they have already invested in that are not on the ‘approved’ broadcasters list of cameras.

The Nano Flash itself can record MPEG2 Quicktime and MXF upto bit rates of 280Mbps. Listed below are the different formats supported by both Final Cut Pro and also Media ComposerFinal Cut Pro

If using Final Cut Pro (version 6.0.3 or version 7.0.x) you should record Quicktime files. Final Cut Pro supports playback of all bit rates of Quicktime files created by a Nano Flash. You should create a timeline with the XDcam HD 422 codec but with the Render Control set to ProRes (this is under User Preferences > Render Control). Please note though that Final Cut can playback (decode) any bit rate, as soon as you render you are rending down to a 50Mbps stream (it cannot encode higher than 50Mbps).

Avid Media Composer

You will need to be running Media Composer 3.1.1 or better to take advantage of Nano Flash recordings. Ideally you should be running Media Composer 5.0.3.2 or later which is when AMA file link support was introduced (no SD file support with AMA linking). Some pointers to follow

  • With Media Composer 3.1.1 you can only import files.
  • When using Media Composer you should record i-frame only MXF Files on the Nano Flash.
  • MC also supports Long-GOP 50 Mbit but this is more taxing on the system so best avoided.
  • 720p 24/25/30 frame rates are supported but only up to 50 Mbps rate.

As with Final Cut Pro, Media Composer can playback (decode) files up to 280Mbps but will render any effects work down to 50Mbps. With the introduction of Media Composer 5.5 you will need to download the Avid AMA MXF plugin from the address below

If you wish to check the recorded bit rate of your .MOV or MXF files either play the files back in Quicktime and check the Inspector or you can use XDCam Browser software which will also tell you.
