LosslessCut ~ Lossless Audio Video Editing

Posted by tom2tec on

The swiss army knife of lossless video / audio editing

LosslessCut aims to be the ultimate cross platform FFmpeg GUI for extremely fast and lossless operations on video, audio, subtitle and other related media files. The main feature is lossless trimming and cutting of video and audio files, which is great for saving space by rough-cutting your large video files taken from a video camera, GoPro, drone, etc. It lets you quickly extract the good parts from your videos and discard many gigabytes of data without doing a slow re-encode and thereby losing quality. Or you can add a music or subtitle track to your video without needing to encode. Everything is extremely fast because it does an almost direct data copy, fueled by the awesome FFmpeg which does all the grunt work.

Features:

  • Lossless cutting of most video and audio formats
  • Losslessly cut out parts of video / audio (for cutting away commercials etc.)
  • Losslessly rearrange the order of video / audio segments
  • Lossless merge / concatenation of arbitrary files (with identical codecs parameters, e.g. from the same camera)
  • Lossless stream editing: Combine arbitrary tracks from multiple files (ex. add music or subtitle track to a video file)
  • Losslessly extract all tracks from a file (extract video, audio, subtitle, attachments and other tracks from one file into separate files)
  • Batch view for fast multi-file workflow
  • Remux into any compatible output format
  • Take full-resolution snapshots from videos in JPEG / PNG format
  • Manual input of cutpoint times
  • Apply a per-file timecode offset (and auto load timecode from file)
  • Change rotation / orientation metadata in videos
  • View technical data about all streams
  • Timeline zoom and frame / keyframe jumping for accurate cutting around keyframes
  • Saves per project cut segments to project file
  • View FFmpeg last command log so you can modify and re-run recent commands on the command line
  • Undo/redo
  • Give labels to cut segments
  • View segment details, export / import cut segments as CSV
  • Import segments from: MP4 / MKV chapters, Text file, YouTube, CSV, CUE, XML (DaVinci, Final Cut Pro)
  • Video thumbnails and audio waveform
  • Edit file metadata and per-stream metadata
  • Edit per-stream disposition
  • Cut with chapter marks
  • Annotate segments with tags
  • View subtitles

Ultimate Mono2Stereo ~ Better Mono To Stereo

Posted by tom2tec on

What sets this frontend for ffmpeg apart from other stereo simulators is it creates an illusion of actual stereo separation. More importantly, it produces none of the weird phasing, and/or time delay artifacts. And very little, if any of the tone discoloration, when those others aren’t meticulously set up just right. All this is accomplished by using the ffmpeg crossover audio filter to split the sound into 8 frequency bands. The split points are based on center frequencies of a typical 1/3 octave equalizer. Those 8 bands are then panned in varying degrees to left and right. The varying width of each band is set to achieve the best balance between the left and right channels.

PS3 Media Server ~ Cross-platform Media Server

Posted by tom2tec on

PS3 Media Server is a DLNA-compliant UPnP Media Server. Originally written to support the Sony PlayStation3, PS3 Media Server has been expanded to support a range of other media renderers, including smartphones, TVs, music players and more. Because it is written in Java, PS3 Media Server supports all major operating systems, with versions for Windows, Linux and Mac OS X.

The program streams or transcodes many different media formats with little or no configuration. It is powered by MEncoder, FFmpeg, tsMuxeR and AviSynth, which combine to offer support for a wide range of media formats.

FFmpeg ~ Open Source Audio Visual Toolset

Posted by tom2tec on

A complete, cross-platform solution to record, convert and stream audio and video. FFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created. It supports the most obscure ancient formats up to the cutting edge. No matter if they were designed by some standards committee, the community or a corporation. It is also highly portable: FFmpeg compiles, runs, and passes our testing infrastructure FATE across Linux, Mac OS X, Microsoft Windows, the BSDs, Solaris, etc. under a wide variety of build environments, machine architectures, and configurations.

Dynamic Audio Normalizer ~ Advanced Normalization

Posted by tom2tec on

Dynamic Audio Normalizer is a library for advanced audio normalization purposes. It applies a certain amount of gain to the input audio in order to bring its peak magnitude to a target level (e.g. 0 dBFS). However, in contrast to more “simple” normalization algorithms, the Dynamic Audio Normalizer dynamically re-adjusts the gain factor to the input audio. This allows for applying extra gain to the “quiet” sections of the audio while avoiding distortions or clipping the “loud” sections. In other words: The Dynamic Audio Normalizer will “even out” the volume of quiet and loud sections, in the sense that the volume of each section is brought to the same target level. Note, however, that the Dynamic Audio Normalizer achieves this goal without applying “dynamic range compression”. It will retain 100% of the dynamic range within each “local” region of the audio file.

The Dynamic Audio Normalizer is available as a small standalone command-line utility and also as an effect in the SoX audio processor as well as in the FFmpeg audio/video converter. Furthermore, it can be integrated into your favourite DAW (digital audio workstation), as a VST plug-in, or into your favourite media player, as a Winamp plug-in. Last but not least, the “core” library can be integrated into custom applications easily, thanks to a straightforward API (application programming interface). The “native” API is written in C++, but language bindings for C99 Microsoft.NET,  Java,  Python and Pascal are provided.
