HD Splitter is a small tool intended for splitting and merging High Definition Blu-Ray audio and video files. HD Splitter works with AC3, EC3, DTS, DTS-HD, WAV (PCM), MLP, M2V, AVC, VC-1. There are two main modes of the program: "Split every file from list" and "Merge all files before". In first case the program divides every file by pieces according to durations that were previously set of user. In second mode program merges several files with the same format into single file and then proceed splitting. The tool uses two ways for time setting: in milliseconds as real-time mode and video frames according to video format. There are such video frame rates used in HD Splitter: 23.976, 24, 25, 29.97, 50, 59.94. You can also set times as durations from existing files, for example if you want to split source file according to existing files.
