An avseq file is a particular way of encoding video files. These files are named avseq.dat and are used when placing a video file into a VCD (virtual CD image). A .mp4 file is a video file using the MPEG-4 compression format. The avseq.dat file within the VCD can be converted to an .mp4 video using the appropriate software application.

Use YASA Video Converter (free trial, see Resources). In addition to reading and converting .dat files to .mp4, the software has many options to customise the output file.
