The problem is, that the speed change function for clips supports only 2 digits after the decimal, so I can only slow it down 0.12 or 0.13 times. My next plan was to place the Video and the Audio in the timeline, slow down the Audio to 0,125x speed, so it would match the Video clip and then just cut in the timeline. Removed support for libvo-aacenc and libaacplus. My plan was to sync up the Audio with the Video first and then start cutting, but it seems the Synchronize feature in the Media Pool is not for that. FFmpeg 3.0 'Einstein', a new major release, is now available Some of the highlights: The native FFmpeg AAC encoder has seen extensive improvements and is no longer considered experimental. Now I planned to cut the slow motion recording and speed it up to real-time where people speak and to slow-motion again where the action happens. The camera also created an AC3 Audio file, containing the Audio in real-time.

The most simple way of doing this is to take a. changes, and a limited distribution, review, and testing. Playing it back, it shows the 'action' 8 times slower than it happend. development mailing-list and make sure that they are applied.

The camera created a Video file without Audio containing the 1080p 29.97fps Video file. I have a 8x slow motion recording from my Camera.
