Alparysoft Lossless Video Codec

Alparysoft Lossless Video Codec is for encoding (compression) and decoding (decompression) of video.
- Without any mathematical losses (i.e. source and destination video are absolutely identical after encoding/decoding process), the compression ratio is twice - 5 times.
- Without any visual losses, i.e. human eye won't be able to see any difference between source and destination video, the compression ratio is 5-15 times.

Source video
Convert to YV12 (with data loss) - when a flag is set up codec converts input formats in YV12 that allows increasing the speed of video editing and to shorten the size of output file greatly. Any losses on conversion to this format are practically not visible.
Adjust interlace - when a flag is set up codec divides a frame into two half-frames and it encodes them separately. It allows increasing compression ratio on video with a high percent of interlaced areas.

Encoding
Lossless compression - on selecting this option codec encodes video without any mathematical losses, i.e. the compressed video is absolutely identical to source one. The compression ratio is 1,5- 5 times at that.
Enable prediction - when the flag is set up codec turns on the algorithm of prediction that allows increasing of compression ratio, but it slows down the speed of encoding/decoding.
Realtime, average, max compr. (max compression) - codec uses different algorithms of encoding, depending on a selection of one of this options. Realtime is the fastest algorithm. Max. Compr.- is the slowest one though its compression ratio is higher than in realtime. Average- it is middle between them according to speed and compression ratio.
Visually lossless compression - on selecting this option codec encodes video with mathematical losses, but without video deterioration (on the right fitting of compression level). It allows increasing of compression ratio up to 5-15 times.
Compression level - allows selecting of video compression ratio. 1 - Almost lossless compression, the least compression ratio. 6- The greatest compression ratio though video deterioration is possible at that.

Decoding
Vertical flip video - flips video upside down. It is necessary sometimes because of working peculiarities of multimedia equipment and multimedia programs. If your video is suddenly played upside down set this flag then.

SSE acceleration
Enable (auto detect) - allows disconnecting of using the multimedia extension of AMD and Intel processors. The speed of video compression/decompression increases greatly when a flag is set up.

Debug
Enable logging - allows recording of debugging and housekeeping data in a file selected.
More detailed info - allows recording of more detailed debugging and housekeeping data in a file selected.
Log filename - shows file's name and location where debugging and housekeeping data will be recorded to.
Browse file - allows selecting the file for recording of debugging and housekeeping data.
View log - allows browsing the file into which the record of debugging and housekeeping data generated.
Clear log - allows cleaning the file into which the record of debugging and housekeeping data generated.
