If you are dealing with creating apps you may have come to the situation to want to make a short promotional video for your app.

If you're a developer, then you're probably not a designer, and making such a video is a demanding job.

You should probably leave this job to someone else, but for the right result, you probably would need a lot of money.

However, there are sites that can help you create the video clips yourself.

One of those sites that I particularly liked was Renderforest

In just two hours, I managed to make a pretty good promotional video.

The thing is very simple.
- Choose video templates that are right for you
- enter a custom text into your video feeds and insert your pictures or video
- Sort the templates as you like

Once you're ready to customize your stuff, you're ready to create a video.

It's alsol possible to customize the theme, color palette and music.

You can select music from a rich collection of available songs or upload your own song or speech.

And that is it, your promotional video is ready for publishing.

There are some others things I also liked about the "Renderforest".

Your pictures are saved online at the "Medial Library" so you do not have to look for them constantly on your computer.

This is very useful when you are playing custom templates.

I also like the option that you can adjust the duration of each template.

It's simple, with "Renderforest".
