Ani-x264

Ani-x264 is an advanced tool designed as a graphical interface for encoding audio and video files in batch mode. It supports MP3, MP4, AVI, AAC, AC3, AVS, D2V, MKV, WAV, RM, RMVB, M4A, OGG and OGM for the input, and it can produce MP4, MKV and M4A files.

Customizable setup

Apart from the core files, the setup kit includes AviSynth (video processing tool), along with FFDShow and Haali Media Splitter (DirectShow decoding filters). Any of them can be excluded from installation. .NET Framework 2.0 and Nero AAC Codec are required, and elevation rights might be necessary to launch the application, in order to prevent startup errors.

Standard GUI with advanced options

The GUI consists of a standard window split into multiple panes. Media files can be dropped in the frame and previewed in your default media player. Using the x264 encoder, it's possible to select the audio or video stream (or both), output file type, and one of the numerous profiles available for the target media.
Ani-x264 enables you to choose the saving directory, set a prefix or suffix to the new file names, overwrite existing files, skip conflicts or add a random number to the new files, exit the tool or turn off the PC on task completion, as well as to keep or delete temporary files.

Configure audio and video settings

Furthermore, you can select the job's priority level, examine log details with any errors, pick the video bit rate and number of encoding passes, opt for average, constant or variable bit rate, as well as encode all audio and subtitle tracks or just the preferred ones.
When it comes to AviSynth filters, it's possible to resize and deinterlace the video, soften or sharpen the image, reduce noise, flip the image vertically, apply a fade in and out effect, and specify a delay for desynchronized audio. Meanwhile, expert users can tinker with standard and advanced x264 settings.

Conclusion

All in all, Ani-x264 features numerous advanced options for experienced users looking to encode audio and video files. Unfortunately, it hasn't been updated for a long time and we've experienced compatibility issues on newer Windows editions.
