* **MPEG-4 AVC (x264):** A widely used codec that offers good compression and quality.
* **MPEG-2:** An older codec, still used for DVDs and some broadcasting applications.
* **Copy:** Copies the original video stream without re-encoding (use this only if you haven’t made any changes that require re-encoding).
2. **Configure Video Codec Settings (Optional):** If you selected a codec like x264, click the “Configure” button to adjust the codec settings. This allows you to control the quality, bitrate, and other parameters. For beginners, the default settings are usually sufficient.
3. **Choose Audio Codec:** In the left panel, under “Audio Output”, select the desired audio codec. Common codecs include:
* **AAC (FDK_AAC):** A modern audio codec that offers good quality at low bitrates.
* **MP3:** A widely compatible audio codec.
* **Copy:** Copies the original audio stream without re-encoding (use this only if you haven’t made any changes that require re-encoding).
4. **Configure Audio Codec Settings (Optional):** If you selected a codec like AAC or MP3, click the “Configure” button to adjust the codec settings. This allows you to control the bitrate and other parameters. Again, the default settings are usually sufficient for beginners.
5. **Choose Output Format:** In the left panel, under “Output Format”, select the desired output format. Common formats include:
* **MP4:** A widely compatible format that supports various codecs.
* **AVI:** An older format that is still supported by many devices.
* **MKV:** A flexible format that can contain multiple video, audio, and subtitle streams.
6. **Save the Video:** Click on “File” in the menu bar and select “Save” or “Save As”.
7. **Choose a Filename and Location:** Enter a filename for your video and choose the directory where you want to save it.

Advanced Features and Tips
While Avidemux is designed for basic editing, it also offers some advanced features that can be useful for more complex tasks.

* **Scripting:** Avidemux supports scripting, allowing you to automate repetitive tasks or create custom filters.
* **Batch Processing:** You can use Avidemux to process multiple video files at once, applying the same filters and encoding settings to each file.
Tips for Better Results
* **Experiment with Filters:** Don’t be afraid to experiment with different filters to see what effects they can create. However, be mindful that applying too many filters can degrade the quality of the video.
* **Use Appropriate Codec Settings:** Choose codec settings that balance quality and file size. Higher bitrates result in better quality but also larger files.

* **Video Playback Issues:** If you experience choppy or distorted playback, try adjusting the video codec settings or using a different video player.
* **Encoding Errors:** If Avidemux fails to encode a video, check the codec settings and make sure they are compatible with the output format. Also, ensure that your system has enough resources (CPU, memory) to handle the encoding process.
* **Filter Problems:** If a filter causes unexpected results, try adjusting its settings or removing it altogether. Some filters may not be compatible with certain video formats or codecs.
* **Audio Sync Issues:** If the audio and video are out of sync, try adjusting the audio delay in the audio settings or re-encoding the video with different audio settings.
