Avidemux is a video editor for straightforward cutting, filtering, and encoding jobs. It trims clips, joins segments, applies filters, and converts containers or codecs, with a stream copy mode that saves edits without re-encoding.
Avidemux is a video editor built for quick, specific jobs rather than long-form production. You open a file, mark start and end points on the timeline, and either save the selection directly or run it through filters and an encoder. Because the default mode copies the existing video and audio streams, trimming a clip takes seconds and leaves the original quality untouched. When a cut does not line up with a keyframe, the program can re-encode just the affected portion, and the same window handles format changes, frame rate adjustments, and simple visual corrections.
Automation is where Avidemux separates itself from drag-and-drop trimmers. Jobs can be queued and run in the background, the whole application is scriptable, and the same operations can be driven from the command line for scheduled or repeated work. Output settings cover the common containers and a range of codecs, so a recording can be repackaged without touching a full editing suite. Filters handle cropping, resizing, deinterlacing, sharpening, colour adjustment, and burning subtitles into the picture. When subtitle work needs to be authored rather than just burned in, Aegisub is the dedicated tool for timing and styling the script first.
The reason to keep Avidemux installed is that most video tasks do not need a timeline editor. Removing adverts from a recording, extracting a single scene, stripping an audio track, or changing a container are all jobs it finishes in seconds because the video streams are copied rather than decoded and rebuilt. That also means no generation loss: a clip trimmed in copy mode looks exactly like the source, which matters when the material is going to be encoded again later. When the source has been cut badly, the smart copy options repair the damage around the cut points instead of forcing a full re-encode. Filters, the job queue, and a scripting interface cover the repetitive work that would otherwise be manual, and the command line interface makes the whole thing usable from a script.
Key capabilities and highlights.
In copy mode the video and audio streams are written straight into the new file, so a trim finishes quickly and the quality is identical to the source. Only the frames outside your selection are discarded, and nothing is recompressed.
Cuts that fall between keyframes create broken references if they are copied blindly. Avidemux can re-encode just the frames near the cut point, which keeps the edit accurate while leaving the rest of the clip untouched and still avoids a full rebuild of the file.
A filter chain handles cropping, resizing, rotation, deinterlacing, sharpening, blurring, colour and brightness correction, and logo or watermark overlays. Filters are previewed on the actual footage before encoding, so you can judge whether a fix is worth the quality cost.
Files can be repackaged between common containers and re-encoded with modern or legacy codecs, with separate choices for video and audio. That makes Avidemux useful for preparing material that a television, phone, or older player refuses to open in its original form.
Video and audio are handled independently, so a clip can keep the original soundtrack, be re-encoded to a different audio codec, or have its sound replaced entirely. Both streams are selected separately, which suits extracting audio or swapping a track without touching the picture.
Several saving operations in Avidemux can be lined up in a queue and processed one after another without supervision, which is practical when a set of clips needs the same treatment. The queue also accepts jobs generated by scripts, so routine work can be scheduled rather than clicked through.
The editor is scriptable, and every action available in the interface can be driven from a script or from the command line. That is how people trim hundreds of recordings consistently, generate variants from one source, or fold a step into an existing processing pipeline.
Avidemux offers markers, keyframe jumping, and frame stepping that make it possible to land on an exact cut point, and the selection between the A and B markers is what gets saved. Zooming the timeline and previewing the selection keeps long recordings manageable without scrubbing through the whole file.

Common questions about Avidemux.
Short, specific jobs: trimming a clip, removing adverts from a recording, extracting or replacing an audio track, applying a quick filter, and converting a file so another device will play it. It is not a timeline editor for multi-track projects, and it does not try to be.
Not by default. Copy mode writes the existing streams into the new file, so quality is preserved and processing is fast. Re-encoding only happens when you ask for it or when a cut point cannot be copied cleanly, in which case the affected frames rather than the whole file are rebuilt.
Yes. Files can be opened in one container and saved in another, with the video and audio codecs chosen separately. Where the existing streams are already compatible with the target container, the conversion is a repackaging job rather than a re-encode, which keeps both time and quality intact.
The same program can be run with arguments, and the application is scriptable, so repetitive work can be handled without the interface. Jobs can also be built up in a queue inside the window and then left to run in the background, which suits overnight batches of similar files.
Yes. A subtitle filter renders text subtitle files onto the frames during encoding, which is useful when the target player ignores sidecar files. The subtitles have to be authored properly first, and a dedicated subtitle editor is the usual place to handle timing and styling before the burn.
It handles the common consumer and broadcast containers, along with the codecs that typically sit inside them, including older MPEG-2 material from DVD-style recordings and modern H.264 or HEVC video. If a file opens but cannot be saved in the format you want, changing the output settings usually solves it.
