Below is a description of the two different codecs.
H.264
Very commonly used compression offering a good compromise between image quality
and file size. Most playback devices made in the last ten years will be able to view files
compressed with this codec up to at least HD resolution.
H.265
Highly efficient compression capable of halving the size of video files for a given
image quality compared to H.264. This codec is excellent for packaging high quality or
Ultra HD video, but may need more up to date playback software and hardware to watch.
NOTE For more information on the difference between H.264 and H.265 see
the 'recording' section of this manual.
Bit Rate
The bit rate setting determines how much video can be recorded to your SD cards and the
quality of the video recording. There are three options you can choose.
High
Select 'high' when you want the highest quality video with the least compression.
Medium
Use the medium setting if you want to fit more video on your SD cards but also want to
have very good image quality.
Low
Select 'low' if you want to fit the most video on your SD cards and you don't need the
highest video quality. This setting will use the most compression so you may see visible
compression artifacts in your recording.
NOTE The built in H.265 encoder uses the latest compression technology
which means you get high quality video recordings using the least amount of
data. Even at the lowest quality setting, with the most video compression, the
quality of your recording will still be very good.
