Version history / Release notes / Changelog / What's New
Version 1.7 (2021.01.25)
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.
The metadata settings are now saved to the configuration file and restored the next time the program is started.
FFmpeg encoder parameters window (F2): information has been divided into groups displayed on separate lines, which facilitates parameter analysis.
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 \\.
When saving the report to a text file in the File properties window, 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.
Displaying additional information in the error log window.
UTF-8 encoding (instead of the system code page) is used when writing the error log to a text file.
Improved handling of user-created profiles.
Lots of minor changes and fixes to the source code and the program interface.

All features
The program also allows you to split input files based on chapters (often found in M4B files).
Metadata by default are copied from the source files, but the user can add their own tags.
To convert audio streams to MP3 the application uses the latest version of the LAME encoder. The program supports encoding with a constant bit rate - CBR, average bitrate - ABR and variable bit rate - VBR (based on LAME presets).
GUI for the FFmpeg, FFprobe (custom builds) and MediaInfo.dll

I'm first reviewing the older 1.5 version. Excellent! Only quibble is H265 option is no good for XP. Now the newer 1.6 version more super work, but the H265 is again tortuous to use even in Win10. Don't use H265 unless you have some super NASA like CPU. Apart from that wonderful little program to convert H264.

One of the best looking and function freeware programs i have seen.
Had trouble with m4b files on some other freeware progs but this program them converted easily, tags included with no problems.
Other things to note:
-attempts lossless conversion
-conversion profiles
-Dark mode skins out of the box!!!!
-Scalable fonts
-UI can be hidden/exposed depending on level of control.
-Lots of options on the expose UI so less menu/window clicking.
-Dark mode skins out of the box (did i mention this? So good!)!!!!
This feels like a paid application for free.
Thanks Jacek!
