-Linux video and audio editors generally support every possible codec they can, and that's quite a lot. This affords you great freedom, but should you experience performance issues while working with a file format, consider extracting the video and audio streams from their compressed containers and working with them as native or [mostly] uncompressed files.+Linux video and audio editors generally support every possible codec they can, and that's quite a lot. This affords you great freedom, but should you experience performance issues while working with a compressed ​file format ​(such as MP3, Vorbis, Theora, Dirac, and so on), consider extracting the video and audio streams from their compressed containers and working with them as native or [nearly] uncompressed files.
  
-If you do convert media, you obviously want to avoid losing quality, so ensure that you are using a //less// compressed container, and that you are retaining the exact same settings as the source video.+If you do find that you need to convert media, you obviously want to avoid losing quality, so ensure that you are using a //less// compressed container, and that you are retaining the exact same settings as the source video.
  
 If ''​mediainfo''​ or ''​video-meta''​ reports a bit rate of 67M at 29.97 fps, then when you convert, use at least 67M for the bit rate and 29.97 for the frame rate. If ''​mediainfo''​ or ''​video-meta''​ reports a bit rate of 67M at 29.97 fps, then when you convert, use at least 67M for the bit rate and 29.97 for the frame rate.
