How to create a fake trailer with blender 3d – Part 3: Finalize

Hi together,

i hope you enjoyed the first 2 parts of „How to create a fake trailer with blender 3d“ (Part 1, Part 2)

In the last part we will combine  our separate scenes and add sounds to it.
Before we start, i have to say sorry to you – we don’t use blender in the last part. For adding sound and combine videos i will use openshot ( it’s a very simple and powerful video editor and it is open source. Unfortunately the program is only available for linux  at the moment.

If you have further questions – ask me:


Openshot (
The trailer in mp4 format (here you can convert youtube movies

4.) Now put the explosions in the 3rd and 4th line. If you want, you can put the sounds in one track, but i think it is more clear (but it depends on the length of the sound-sample you use)
