ffmpeg 6.0 breaks hevc_nvenc
Latest 3.0.0 version comes with a new ffmpeg executable.
Since ffmpeg 6.0, nvidia hevc_nvenc hardware encoder fails (No capable devices found).
New patched 2.8.8 version uploaded
Due to a change to avoid unintended overwriting, all paths and filenames were automatically set to lowercase in version 2.8.8.
I've re-uploaded version 2.8.8 to address this issue in a different way, so only file extensions are set to lower case.
New setting to set an output target size
Now at Two pass encoding wizard, there's a new option to set an output fixed target size. File bitrate is automatically calculated depending on file duration. It is also possible to skip first pass.
New quick file listing feature tests
Using the new setting: Quick file listing, thousand of files can be loaded in just a minute.
Together with adding an exception in your antivirus for ffmpeg.exe you can achieve speeds
of tens of files per second using multi-file encoding: 3812 files processed (stream copy) in 2:30 minutes.
Collaborative presets database
I have created this collaborative document to expand application presets, so users can provide or obtain useful ffmpeg configurations
for the application of ffmpeg itself.

Patched version executable v2.5.0 for burn subtitles bug
- Patched v2.5.0 FFBatch.exe
To replace current v2.5.0. Fixes a bug with Batch Burn subtitles feature (subtitles filter bug with absolute paths).
Translation project
Hi, I've started with the first localization stepsin order to make application available in more languages.
Project in itself is going to be a very long task, so if you can contribute to this time consuming effort, please consider a donation.
Thanks in advance.
How to batch split files using FFmpeg Batch AV Converter
For example, to split a bunch of mov files in 30 seconds segments, use this setting:
Parameters: -acodec copy -f segment -segment_time 30 -vcodec copy -reset_timestamps 1 -map 0 %fp\ffbatch\%fn_%0d.mov
Format: nul
This command will generate 30 seconds videos from mov files saving it at input source file \ffbatch folder, using the source file name.
Display bug on v.2.2.5 or earlier
Bug report: When hovering a file list item, its contents disappear, and once mouse leaves the item cell, contents appear again.
This updated 2.2.5 version solves the issue.
Just replace your current executable with this one.
Latest version Linux Wine compatible
After some tweaking, it is now available a new version that should run on Linux using Wine or Crossover, with no major performance loss.
Just extract the package and follow readme file. (Tested on Ubuntu 18.04 LTS and Wine 5.0).

Issues with multi-file processing solved
Multi-file processing, a distinctive feature of FFmpeg Batch AV Converter, has experienced random issues in fast computers, causing crashes, missing output files.
After some digging, long timed searched cause has been found, so now multi-file processing should work reliably on any computer.
In case you use this feature, you can replace your current executable with this updated version:

Two pass video encoding wizard in progress
Next release will include a two pass video encoding wizard (may require some user tweaking.)
Next update 2.0.1 coming soon with filtering features
Next release will come with and advanced file list filtering feature, to select files by information like:
- File size, extension, bitrate.
- Audio/video codec, bitrate, frame rate, frame size.
- Custom search of any string on file streams and multimedia header information.
New version 2.0 coming soon
Next FFmpeg Batch A/V converter version will jump to 2.0.0, keeping compatibility with 1.6.X.
It will come with multiple changes and suggestions from the user community.
- New main menu and settings panel for better user experience.
- Presets can now be overwritten.
- Overwriting source files now supported.
- Avoided output overwriting of two list items with the same name but different extensions.
- Source files path can be used and saved as default relative path.
- Time elapsed displayed during queue processing.
- Queue information can now be saved as a .ffq file (FFmpeg Batch queue session file).
- Option to enable/disable the creation of log files.... read more
