Proxy recording

You can record a low bitrate proxy file at the same time as recording the high bitrate original movie file.

The proxy file is suitable for data transferring as the size of proxy files is smaller than that of the high bitrate original movie file.

Proxy recording is supported only when [FILE FORMAT] is set to [XAVC S 4K] or [XAVC S HD].
