I can create AVI files in my Tecplot product with the compression set to Lossless Uncompressed to play on a Linux or Macintosh platform but these files are very large. Is there a way to make them smaller but still able to play on these platforms?
Yes. You can encode the uncompressed AVI files to MPEG4 which reduces the size to a fraction of the uncompressed size while preserving the quality of the image. You can play MPEG4 files using Quicktime.
