Whats new in NuEnc 0.01b:
- Fixed Buffer Status progress control bug (thanks to dragongodz)
- CQ mode encoding is now vbv compliant (I hope! Only testing will tell...)
Whats new in NuEnc 0.01a:
- Fixed (almost) all GUI problems
- Added a few more matrices to 'matrix.ini'
- CQ mode encoding is now linear (very close to anyway)
- NuEnc will not crash if you specify a too high bitrate for x-pass
- Now even smaller than last release
Whats new in NuEnc 0.01:
- GUI Re-arranged
- New encoding window displays comprehensive encoding statistics
- Now able to change more options such as motion search diameter and minimum bitrate
- Now less than half the size compared to previous versions (~300KB)
- Constant quality encoding added (experimental at the moment)
- Custom matrix support via 'matrix.ini' and external XviD style matrix files
- Field order can be changed for interlaced encoding
- Implements the latest changes I've made to avcodec
- Fixes to multi-pass encoding. More passes will never decrease quality.
Whats new in NuEnc 0.00d (only minor changes):
- Compiled to work with Pentium 4 properly (oops)
- Reduced possibility of underflow more by restricting the amount of remaining buffer that can be used (90%)
- Probably other changes I've forgotten
Whats new in NuEnc 0.00c (only minor changes):
- Increased scene change sensitivity (reduces filesize)
- Changed degradation/improvement for bitrate targetting (improves quality at all bitrates)
- Slight rate control correction (improves quality at low bitrates)
- Changed default macro block decision to 1
- Changed QLB matrix to Notch matrix (but I think that the QLB matrix was better for low data rates...)
- Probably other changes I've forgotten
Whats new in NuEnc 0.00b:
- Multipass encoding
- Ability to force key frames (for chapters, commandline only option)
- Number of buffer underflows are reported
- Able to keep intermediate passes for comparison
- Turbo mode for faster first pass stats gathering (at cost of negligible inaccuracies in stats)
- Able to turn dynamic b-frames on and off
- Able to alter the rate control frame variance (1 for high quality/high bitrate, ~0.5 for low bitrate, default 0.75)
- Enabling dynamic b-frames allows B frames to change to I frames on a scene change (originally P frames could only change to I frames).
- Commandline options now work :)
Commandline example: NuEnc -i G:\Trailer.avs -o G:\Trailer.m2v -maxbitrate 2520 -pass 2 -mpeg2 -vbr -hq -scene -gopsize 35 -forcekey ( 1 2 3 4 5 6 7 8 69 ) -keep -buffer 112 -turbo -rc_var 0.6 -dynamic
This will force frames 1-8 and 69 to be keyframes (note the spaces, they are important).
