Video Audio Replacer

Video Audio Replacer allows users to replace the audio component of a video file without touching or re-encoding the visual stream. It supports a wide range of video containers including MP4, MKV, and MOV, ensuring that the final output maintains bit-for-bit identical picture data. The software includes intelligent handling for duration mismatches, offering options to trim, pad with silence, or extend with black frames. It also provides a lossless mode to preserve high-quality WAV or FLAC audio tracks during the swap process.
