Panasonic HX-WA2A Owner's Manual page 54

≥ The images recorded between pressing the recording start/stop button
to start recording and pressing it again to pause recording become one
scene.
≥ If the file size exceeds 4 GB during recording, the unit saves the file
and saves the continuation in a new file. (A new file is created
automatically every 4 GB (l 192))
≥ While recording is in progress, the recording will not stop even if the
LCD monitor is closed.
≥ Please refer to page 191 for details about approximate recordable
time.
About the compatibility of the recorded motion
pictures
≥ They are not compatible with devices other than those that support
MP4. Images cannot be played with equipment that does not
support MP4. Confirm that your equipment supports MP4 by
referring to the operating instructions.
≥ There are some cases where the recorded motion pictures cannot
be played back, even if the device supports MP4. In such a case,
play back on this unit instead.
