 When you open a video file using the Open button (Ctrl+O) on the main toolbar, there are 3 basic things you can do with it in Avidemux: When you open a video file using the Open button (Ctrl+O) on the main toolbar, there are 3 basic things you can do with it in Avidemux:
  
-  - **Cutting**\\ //Why//: For example, cutting out ads from a TV recording, or saving only a small part of a video you are interested in.\\ //How//: Select a portion of the video with the mark A and mark B buttons, and either delete, copy, paste or save that part. If you do not reencode the video (that is, if the encoder is set to Copy), make sure all segments start with keyframes, or the resulting video will be broken at cut points. See the [[using:​cutting|cutting]] chapter for more details.\\ \\  +  - **Cutting**\\ //Why//: For example, cutting out ads from a TV recording, or saving only a small part of a video you are interested in.\\ //How//: Select a portion of the video with the mark A and mark B buttons, and either delete, copy, paste or save that part.

-  - **Encoding**\\ //Why//: You may want to convert the video to a different video format that your hardware or software players understands,​ or you just want to compress the video to a smaller size, for archiving or publishing it on the Internet.\\ //How//: Encoding in Avidemux means selecting an encoder that does the video compression. That is, the drop-down menu on the left cannot be set to Copy. See the [[using:​main_window_-_qt_version|main window]] chapter for more details.\\ \\ +  - **Encoding**\\ //Why//: You may want to convert the video to a different video format that your hardware or software players understands,​ or you just want to compress the video to a smaller size, for archiving or publishing it on the Internet.\\ //How//: Encoding in Avidemux means selecting an encoder that does the video compression.

   - **Filtering**\\ //Why//: Basic filters applied to the picture like deinterlacing or resizing come in handy for various format conversions. Other filters may be used for adding subtitles to the picture, color correction etc.\\ //How//: Filters require reencoding. So you have to select an encoder first, then you can add filters using the Filters button.

   * **Container format**: audio and video tracks are stored in a single file, in a container. The container format does not influence the audio or video quality, it is only a way of storing video and audio in a single file. In Avidemux, the container format is selected in the (Output) Format section at the left.\\ //Note//: Always select an appropriate container format for the file you are saving! See the [[general:​output formats|Output formats]] chapter for more details. You should also add a suitable extension to the file name when you save the video, like .avi for the AVI container format, or .mkv for the Matroska container format. Avidemux version 2.5 or older does not add the extensions automatically!   * **Container format**: audio and video tracks are stored in a single file, in a container.

-  * **Video format**: this is the way the video stream is encoded in the file, usually in compressed form. Modern compression fomats usually offer better ​size/quality ratio than old ones. Common video formats include H.264, MPEG-4 Part 2 or MPEG-2 Part 2.+  * **Video format**: this is the way the video stream is encoded in the file, usually in compressed form.

   * **Audio format**: the way the audio stream is stored in the file. Common audio formats include AAC, MP3, MP2, Vorbis or PCM (uncompressed).\\ //Note//: Do not confuse audio and video formats with audio and video codecs. Codecs are tools used for encoding and decoding, while formats are methods of encoding the data.

   * **Encoder**:​ this is a tool used for encoding the audio or video stream into the desired format. Some encoders are better than others – even if there are multiple encoders for the same format, one of them may offer higher quality at the same size. In Avidemux, you can select the software encoder in the Video and Audio sections. Of course, the selected encoder then implies the output format as well.   * **Encoder**:​ this is a tool used for encoding the audio or video stream into the desired format.
