Here’s how to install SlowmoVideo, an open-source software to create slow-motion videos, via PPA in Ubuntu 16.04, Ubuntu 15.04, Ubuntu 14.04, and derivatives.
slowmoVideo uses ffmpeg for reading and writing video files, and GPU-KLT+FLOW and OpenCV for calculating the optical flow so it does not simply make your videos play at 0.01× speed. You can smoothly slow down and speed up your footage, optionally with motion blur.
- Videos in any format supported by ffmpeg can be loaded. Image sequences can also be loaded, so, if you did a timelapse with too few frames, slowmoVideo may help as well.
- slowmoVideo does not work with a constant slowdown factor but with curves that allow arbitrary time accelereation/deceleration/reversal.
- Motion blur can be added, as much as you want.
How to Install SlowmoVideo in Ubuntu:
For Ubuntu 15.10 users who’ve GetDeb repository added, you can install the software via Synaptic or apt-get command.
For Ubuntu 14.04, Ubuntu 15.10, Linux Mint 17.x, and upcoming Ubuntu 16.04, slowmoVideo is easy to install via this unofficial PPA.
