MP4 & QuickTime Writer


DirectShow filter for multiplexing and writing .mp4 and .mov files.

Overview

MPEG-4 Writer is a DirectShow filter for multiplexing and writing .mp4 and .mov files. It multiplexes the input streams and writes them to MPEG-4/MOV files.

The filter performs the function of both the multiplexer and the file writer and must be the last filter in the graph.

Features

  • Adjustable interleaving time for input streams
  • Selecting the mode of writing timecodes (only after breaks or all time codes)
  • Selecting the drop/non-drop mode to process 29.97 and 59.94 timecodes.
  • Selecting the mode for writing separate .mdat and metadata files. These files can be merged into one correct MPEG-4 file using "copy /b a.mp4+a.mp4.mdat b.mp4".
  • Allows the shared access to the current writing file. This is a special feature for cutting and writing the selected part of the current file to another file "on fly".
