Software Update: Avidemux 2.8.0

Version 2.8.0 of Avidemux has been released. With this open source and cross-platform program video files can be easily edited and converted. It’s available for Windows, Linux, and macOS, and there are also unofficial versions for BSD. Avidemux is developed in C++, the interface is created with Qt and it uses FFMpeg for its multimedia functions. The changelog for this release can be found below:

Behavior

• The part of video preceding the presentation time of the first frame is now excluded from created segment, making all videos appear as if they “start at zero”.
• When saving video, the frame matching the B marker is now excluded from the exported range. Therefore, if the B marker is set to the last frame of the video, it needs to be reset to the full duration for the last frame to be included into the output.
• Loading Matroska files with HEVC video tracks takes longer as slice headers are decoded to detect the frame type.

New Video Filters

• analyzer
• Blur (on selected area)
• cartoon
• Color balance (adjust shadow, midtone and highlight)
• Chroma hold (monochrome effect with kept colors)
• Chroma key (replace “green screen” with an image)
• Deband (reduce banding artifacts)
• DelogoHQ (clean up arbitrary shaped logo)
• Dynamic Threshold
• Fade from first image
• Fade in (combination of multiple effects)
• Fade out (combination of multiple effects)
• Fade through (combination of multiple effects)
• Fit to size (resize and pad to the specified size)
• Flip (vertically/horizontally flip the image)
• Grid (video wall effect)
• Image stabilizer (reduce camera shakiness)
• Luma stabilizer (reduce flickering)
• mirror
• posterize
• Quadrilateral transformation (four point transform)
• Wavelet denoiser
• wavelet sharpener
• Zoom (partializable crop filter)

New Features

• HDR video can be converted to SDR with tone mapping using a variety of methods.
• FFV1 encoder is back (it was available in Avidemux 2.5.x).
• TrueHD audio tracks can be decoded and are supported for Matroska containers.
• Decoding support for WMA9 Lossless codec.
• Filter previews have got a unified method to quickly compare filtered and unfiltered inputs via the “Peek Original” button.
• Blend and motion interpolation options added to “Resample FPS” filter.
• Mark cut points (segment boundaries) on the navigation slider. New buttons and shortcuts are provided to jump to these cut points.
• In the Video Filter Manager, active filters can be temporarily disabled.
• Preference added to load sequentially named pictures in reverse order, allowing to reverse video by exporting selection as JPEG images and loading the first one.
• During playback navigation is possible via keys or by dragging the navigation slider.
• Other Enhancements
• “Resample FPS” and “Change FPS” filters can handle up to 1000 fps.
• “Crop” filter’s preview has got a translucent green masking.
• “Crop” filter’s Auto Crop function can achieve perfect crops (if the selected frame is not too dark).
• The maximum output resolution of the “Resize” filter has been increased to 8192×8192
• The “Resize” filter has got a nearest neighbor scaling option.
• Improved HiDPI scaling in previews.
• x264 video encoder plugin now allows to specify color properties.
• Maximized window state, widget visibility and toolbar position are preserved after application restart.
• Timestamps in format 00:00:00.000 like copied to clipboard by pressing Ctrl+Shift+C can be pasted into the “Go to Time” dialog using Ctrl+V.
• PulseAudioSimple audio device has been replaced with full PulseAudio, making an in-application volume control available (Linux only).
• ALSA audio device plugin has been modified to use soft volume, providing application-specific volume control which works with every ALSA device.
• In the Video Filter Manager, navigation by keyboard has been enhanced.
• The VU meter (“Audio Metre”) has been redesigned.

Bug fixes

• Occasional UI unrepsonsiveness during playback should be fixed.
• Prevent navigation key events piling up.
• Thumb slider, displaced by mouse wheel, is now automatically reset if the end of video is reached, stopping Avidemux log file from filling disk space.
• Purple tint in old “Fade to” and “Fade to black” filters on macOS fixed.
• Green tint in “MPlayer eq2” filter is fixed.

miscellaneous

• Bundled FFmpeg libraries have been updated to 4.4.1 release.
