TMPGEnc converts AVI files to MPEG-1, the format used in VideoCDs. Using a variety of options, you can compress your video file while retaining high quality. TMPGEnc enables you to adjust the bit rate, the "quantize matrix", the GOP structure, the interlace, and many other parameters so you can create the most appropriate movie file for your purposes. Note that a 30-day trial with MPEG-2 encoding is included. After 30 days, MPEG-2 encoding will be disabled, but MPEG-1 encoding will still be available.
