From iOS 8 onwards, Apple will enable developers to submit App Trailers to showcase their apps to the users.
An App Trailer is a video demonstrating the app. It is in addition to the App Screenshots we know and have used before.
As an owner of an App Portfolio, you need a way to effectively produce App Video Trailers for each of your apps in a cost-effective way.
For a true App Portfolio, however, it may be sufficient to produce just one video explaining your concept and use it to showcase each app from the portfolio.
An important point though is to produce a professional video that makes the users want your app concept.
Here is the rule of thumb:
It is better to produce one video professionally and reuse it for all apps from the portfolio instead of having an individual video for each app done poorly!
To Your Success!
