ELDER Description:
- ELDER Does a parallel 2 pass encode that tries to use the same bit allocation as normal 2pass
- First pass is divided into 2 stages:
- Stage A divides the stream into chunks of the same size
- Stage B corrects the scene changes on the chunk borders (encode from last I-frame of previous chunk to 2nd I-frame of current chunk).
- The second pass is divided into 2 stages:
- Stage C encodes a part of the chunks in parallel both scene and bitrate accurate (a bitrate is assigned to each chunk to give all of them approx. the same quality).
- Stage D corrects for size under- or overshoot
ELDER: parallEL encoDER for XviD and X264
Known issues:
- zones don't work and are hard to do since it interferes with the trim command
- size is sometimes off target if chunks are too small
ToDo during beta:
- beta6: fix pause/resume function
- beta6: add correction stage D for better accuracy and scaling
- beta6: add theora encoding
- add high framerate rate control to ELDER4XVID
- add audio encoding and muxing
- add support for SNOW
- automatic detection of CPUcount
