Ciano
DISGRIFIAD:
The ciano is a multimedia converter for all the format you need. Focused on simplicity, Ciano brings a new approach to using FFmpeg, without the need to write a single command line code. Support for many codecs and containers like MPEG4, MPEG, FLV, AVI, OGG, GIF, VOB, MP3, WMA and many more.. It also supports multiple file selection and conversion.
It is not often that you can find an “all-in-one” converter for Linux. The fact that it can convert videos, photos, and audio files inside one single app is extremely useful. The fact that is simple it is both great and not-so because it lacks a lot of options like selecting the quality of the exported files or any other option of the sort. This app is for those who want to simply convert from one format to another without changing anything about the files in terms of bit-rate, video quality, image resolution, and so forth.
