Image Compression

TroublePix 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, TroublePix 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 TroublePix. You must check and test the codec with TroublePix to make sure the codec performance and compatibility is suitable to your needs.

• AVI codec.
• AVI with CineForm Codec.

NorPix also provides 2 DirectX codecs (paid option):

• NorPix JPEG: for JPEG compression.
• NorpPix H264: for H264 compression.

Both codecs run with most TroublePix image formats and resolutions. They also work with raw Bayer images by applying real time Bayer interpolation and color correction during the encoding.
