Purpose: Does it satisfy a user need or business goal?
Commitment, time, effort
Then – the technical stuff
Sound is very, very important! (make sure audio can stand alone because the audience might be multi-tasking)
Quality of picture, lighting etc.
Quality of extra material such as photos or slides
Graphics – Readability is key
Planning
Once you have all that down: CONTENT!!!
Have a strong story to tell
Jump right in – remember the purpose and the audience and think about your own attention span online
Keep it short but interesting (Promotional videos from 30 sek to 5 min tops – program videos preferably no longer than 30 min – informational video somewhere in between)
Think about visuals
Provide context if necessary but stick to the point
