Avidemux is a freeware, open-supply video editor designed for multi-motive video editing, converting, easy cutting, resizing, filtering and encoding tasks.
It helps many record types, such as AVI, MP4, Matroska, MPEG-2, H.264 and H.265. It does now no longer yet, or handiest in part helps cutting-edge open formats, like Opus, WebM, VP8, VP9 and AV1. Tasks may be computerized the usage of projects, process queue and effective scripting capabilities.
Avidemux permits you to edit maximum video documents with the aid of using your necessities to lead them to play on any decided device. Multi-threading is supported! The graphical consumer interface of Avidemux seems quite just like VirtualDub. The maximum capabilities recognised from VirtualDub are to be had too and natively help brilliant record types, inclusive of AVI, MKV, MPEG, VOB, MP4, TS, ASF, OGM and FLV.
Avidemux can't open uncooked MPEG streams. Instead, it may open listed MPEG streams. The index is a textual content record containing navigation information. It is wanted to permit body accuracy.
As for MPEG streams, a NuppelVideo record has no inner index. Avidemux will rebuild it routinely upon loading (that would take a few minutes).
Avidemux also can open a flow of uncompressed BMP documents (RGB) or a fixed of JPEG documents or a fixed of PNG documents. The cutting-edge model of Avidemux can normally decode the WMV/ASF containers, there are now and then a few documents that also have issues with starting or playing. If you've got that problem, then you may try and area the WMV contents into an AVI container.
Multithreading has been implemented in the following areas of Avidemux (some partially through libavcodec):
- MPEG-1 and MPEG-2 (using libavcodec)
- MPEG-4 Part 2 SP/ASP (using libavcodec or Xvid)
- Earlier versions of Xvid are not compatible with this feature.
- H.264/MPEG-4 Part 10 AVC (using x264)
- H.265/HEVC (using x265)
- MPEG-1 and MPEG-2 (using libavcodec)
- MPEG-4 Part 2 SP/ASP (using libavcodec)
- New HiDPI compatible button set
- A fast method to add partial filters via CTRL+F shortcut
- custom frame rate change (audio stretch with pitch control)
- configurable compressor (DRC)
- 3-band equalizer
- independent channel gain options
- independent channel delay options
- channel remap options
- new downmix options: stereo headphones and headphone virtual surround
- audio track configuration up to 32 tracks
- the volume setting is saved upon exit
- Light and dark theme options in the View menu
- Option to remember selected resize method in “Resize”, “Fit to size” and “Zoom” filters
- New filter: 3D LUT
- New filter: Decimate
- New filter: Arbitrary Rotate
- New video encoder: VideoToolbox HEVC (“ffVTEncHEVC”, macOS only)
- HDR tone mapping performance and quality improvements
- Extended file info
- Rotating mouse wheel over buttons to seek by 60 seconds cycles through 1/2/4/60 seconds seek modes
- Support for decoding 8-bit VP9 in hardware via DXVA2 on Windows and via VDPAU on Linux with graphics cards featuring a VP9 decoder
- Buttons to seek to selection start (A) and end (B) in an on-the-fly video filter preview
- The logo image in the “Add logo” video filter configuration dialogue is now scalable and can be repositioned by dragging
- By default, on-the-fly preview in video filter configuration dialogues is now rendered using OpenGL to improve performance in HiDPI conditions
- Crash on copy to clipboard if selection extends to the end of the video, a regression introduced in v2.8.0
- Crashes in “Resample FPS” video filter with motion interpolation enabled
- Crash on finishing encoding with the vp9 encoder
- Avidemux fell victim to a crash in the VA-API driver triggered by probing on application startup on Linux with some recent hardware
- Crash loading MPEG-TS or MPEG-PS file with MPEG-1 video track and HW decoder via VDPAU enabled
- Wrong number of channels or wrong channel layout with some E-AC3 streams
- Reduced contrast and desaturated colours in loaded BMP images
- Selection starting at zero and ending at the last picture of the video cannot be deleted
- Disabling B-frames breaks VideoToolbox HW encoder (macOS only)
Avidemux can be used on almost all known operating systems and computer platforms. It is available for Linux, BSD, Mac OS X and Microsoft Windows under the GNU GPL license.
