Image Compression

StreamPix performs uncompressed image recording by default. However, some experimental constraints may require image compression. This allows reducing the total amount of disk space needed, but will also compromise the image quality.

When recording to sequence file (.SEQ), the following compression schemes are possible:

  • Lossy JPEG (image quality and compression factors can be fine tuned).
  • H264 (bit rate as a percentage of uncompressed image size).
  • RLE encoding (loss less).
  • Huffman encoding (loss less).
  • LZ encoding (loss less).

When recording directly to AVI or MOV, StreamPix supports, in theory, all available DirectX codecs. Some codecs are freeware, while others are paid codecs. Also, some codecs may not support all of the image formats and resolutions that can be captured with StreamPix. You must check and test the codec with StreamPix to make sure the codec performance and compatibility is suitable to your needs.
