About the JPEG 2000 Codec (J2K)

With MovieRecorder 3.4 or later, you can choose the JPEG 2000 codec (sometimes called J2K). It comes standard with MovieRecorder so you don't need the pro codecs option for that. You will only need the Pro Codecs option if you want to record to MXF.

The JPEG 2000 codec is a high quality codec that is used mainly for archives or film deliveries. This codecs requires a lot of processing power however to encode. But the encoder we use is highly efficient, but there are a few things to know.

 

GPU Limitations

In order to be very efficient, the JPEG 2000 encoder use the GPU and not the CPU (unlike all the other codecs that we encode to which use the CPU). So the better your Graphics card the more channels you'll be able to encode.

Also we currently support only 3 Graphics card, and these are the models used for the Mac Pro 2013 (AMD FirePro D300, D500, D700). We don't support other Graphics card, so you won't be able to encode to JPEG 2000 on older Mac Pros, or MacBook Pros, nor Mac minis.

 

MXF or QuickTime ?

As said earlier, you do not need the Pro Codecs option to encode in JPEG 2000. But without the option you will only be able to record to a .mov file, not to MXF. If you want to record JPEG 2000 in an MXF container, you will need the Pro Codecs option.

 

Playing out JPEG 2000

The Softron playout solutions do not support J2K codec yet, but there are a few players that you can use. Below are some players that support JPEG 2000.

Player MXF QuickTime .mov
Adobe Premiere Pro Yes - Only progressive Yes - Requires the "Avid QuickTime Codecs LE" installed - Only interlaced
Avid Media Composer Yes - Only progressive Yes - Requires the "Avid QuickTime Codecs LE" installed - Only interlaced 
QuickTime 7 No Yes - Requires the "Avid QuickTime Codecs LE" installed - Only interlaced
VLC Yes - But very demanding in CPU, so playback may not be smooth No

Note that this table is subject to change, as we are not the manufacturers of the software above, so we can not guarantee this, and the best is as usual to download a demo version of MovieRecorder and test this in your favorite application.
