FFMPEG is an open source encoding tool that provides the ability to record to a number of formats including MPG, TS, MP4, MOV and MXF.

Select the recording format to use out of MPEG-2, MP4 X264 with AAC audio and VC-3

Depending on the codec a number of file formats will be available.
MXF or the MOV/MP4 non-Indexed formats are recommended as they support file recovery in the event of a power or system failure.


       MP4 creates a video file containing H264 video and AAC audio.
       Due to the complexity of H264 compression, this option requires a faster processor for optimal performance.

       Bit Rate

       Select the Bit Rate for the H264 video stream in Mbps (Megabits per second). 25 is recommended for high quality HD (similar to AVCHD)

       Audio Bit Rate

       Select the Audio Bit Rate for the AAC audio stream in Kbps (Kilobits per second). A maximum of 192kbps can be selected. 128kbps is the default.

Windows 7 File Size
MP4 recordings have a maximum file size limit of 4GB under Windows 7.
For larger recordings, choose a different recording format or upgrade to Windows 10.



     Options are the same as above but with the following additional settings:

     Bit Rate

     Specify the Bit Rate for the MPEG-2 recording in Mbps (Megabits per second). 8 is recommended for SD, 25 for HD.

     File Format

     Specify either Program Stream (MPG) or Transport Stream (TS)

     Transport Stream is recommended if the video will be edited by a program such as Sony Vegas.
