Video Tips!

Output resolution.
Remember standard TV and DVD don’t display high definition (HD) at full resolution. For HD 720 and Full HD 1080 you’ll need the right HD display for optimum viewing. Web video uses a much lower resolution.
Invest in memory.
If you intend to shoot a lot of short sequences then your memory cards will fill up, and fast. One minute of 1080p footage (MPEG4) will take up at least 300MB of space, so it’s worth carrying around spare cards – ones new and fast enough to keep up with the large stream of data too.
Look for the right frames per second (fps).
Video needs to record upwards of 24fps for movement that appears smooth to the eye. For UK playback, 25fps or 50fps is the optimum to be compatible with PAL – the UK display standard.
