The following frames (P‑frames and B‑frames) hold only part of the image information (→ the difference compared to the I-frame), so they need less space to store than an I‑frame, and thus improve video compression rates. See ”Video compression picture types” for details.

Simply install the following package(s):

• avidemux (multiverse)

There are some additional packages, providing special functionality:

• avidemux-cli (multiverse) – optional command line tools, e.g. useful for shell scripts, converting tasks etc..

After installation, you can start the program by clicking “Applications→Sound & Video→Avidemux (GTK+)”. Or open a terminal and start it via avidemux.
