To encode the video and audio files the program uses the FFmpeg encoder (ffmpeg.org).

To retrieve information about video files, the program uses the library MediaInfo.dll (http://mediainfo.sourceforge.net/).

The program is accompanied by a special version of the FFmpeg encoder, adapted to the needs of the program. Not recommended to use other versions of FFmpeg.

Version 2.11 (2021.01.19)

• Updated conversion engine (FFmpeg) and multimedia information library (MediaInfo).
• Information about the conversion progress is displayed on the title bar of the main window and on the taskbar.
• Fixed Stack overflow bug when selecting next files in the list very quickly.
• Added support for files from network shares whose names start with the characters \\.
• Added support for the SoX audio resampler (libsoxr).
• File properties window: when saving the report to a text file, UTF-8 encoding is used (in previous versions the system default code page was used).
• After the user has interrupted the conversion, the program displays a window asking whether to delete the incompletely converted file. Such files usually have a damaged internal structure and cannot be played.
• If incorrect parameters are passed to the conversion engine (FFmpeg) and the conversion process fails, the output file will be automatically deleted. Such a file usually does not contain any data (0 bytes in size) and only unnecessarily litter the disk.
• The ability to display the system File properties dialog for a file selected on the list has been added.
• File properties window: Displaying the CRC32 checksum and MD5 hash of files up to 200 MB in size.
• Added support for additional WAV (PCM) encoders: pcm_s24le, pcm_s32le, pcm_s64le, pcm_u8, pcm_mulaw, pcm_f32le, pcm_f64le.
• Added support for additional AAC encoder: FFmpeg-AAC.
• Fixed display of information returned by FFprobe. In version 2.10, in addition to the actual data, some unnecessary junk information was also displayed.
• Improved handling of user-created profiles.
• New conversion profile: Audiobook-Opus

Version 2.10 (2019.10.15)

• New Vorbis encoder options: bitrate mode, VBR presets, minimum and maximum bitrate, lowpass filter, option to set the output file extension to .ogg or .oga.
• New AAC encoder options: bitrate mode, VBR presets (modes), audio profile and lowpass filter.
• New Opus encoder options: bitrate mode, the ability to set the encoding algorithm complexity, frame duration, low-pass filter, the ability to fine-tune the work of the encoder to process audio files containing music or recorded human speech.
• Improperly selected audio sampling frequencies in profiles using the Opus encoder have been corrected.
• New FLAC encoder options: bit depth, compression level, audio channel mode, multidimensional quantization, precision and linear predictive coding methods and more.

• Displaying the output directory on the title bar of the Output panel. This directory is also displayed when the panel is collapsed, so you no longer have to expand it to see where the resulting files will be saved.
• Added the ability to number the file list in ascending order. This function can be useful after deleting some files, sorting or manually changing the order of files in the list.
• The ability to define two sets of additional command line options passed to the FFmpeg encoder and the ability to set the order of passing these parameters relative to the parameters selected by the program has been added.
• The information module has been extended.
  Data returned by MediaInfo is now also displayed in HTML and JSON format.
  A new tab has been added with the hexadecimal dump of the first 10 KB of the examined file.
  For easier identification, video streams are now highlighted in red, audio – green, subtitles – purple, chapters (menu) – blue.
  The window layout is now saved to the configuration file and restored the next time the program is started.
• Added the option to restore default values for each supported encoder separately. Appropriate commands are in the Encoder menu and on the Audio panel.
• The control displaying the list of available output formats and associated audio encoders has changed. All lossy encoders are highlighted in blue, lossless encoders in purple.
• When turning on dark visual styles, the main window icons are slightly grayed out to reduce the contrast.
• The ability to convert MXF files has been added.
• New language files: Slovak and Slovenian.
• New About window displaying additional information.
• Lots of smaller improvements and bug fixes.
• Support for Windows XP was dropped. Windows Vista or later is required. Maintaining compatibility with Windows XP would prevent the use of new technologies, audio and video encoders, and new FFmpeg features only available for Windows Vista and newer.
