The LEAD H265 Encoder MediaFoundation® transform for compressing and decompressing video data using the H.265/HEVC standard. The standard was developed jointly by ITU and MPEG and the official name is ISO/IEC 23008-2 MPEG-H Part 2 and ITU-T H.265. The H.265/HEVC compression outperforms all existing standards by a factor of three to four especially in comparison to MPEG-2. It also outperforms the H264 standard by a factor of about two.
H265 is a high quality video compression algorithm suited for all types of applications with different ranges of bit rates. The compressed video data can be stored inside AVI, OGG, MKV or MPEG files with the option of saving the file with or without the audio data.
The Encoder requires the libmfxsw32/64.dll file to be installed properly.
The compression options for the Encoder can be set manually through the encoder property page. The compression options can also be set programmatically using the filter interface.
The encoder uses SSE4 instructions, so it will run only on computers whose processors have SSE4 support. Trying to create the encoder on a computer without SSE4 support will return error LTMM_E_SSE4_NOT_AVAILABLE (0x80050051).
