On2 hat den VP7 Personal Edition Codec freigegeben, siehe:
http://www.on2.com/get_vp7.php
Cu Selur
Ps.: Der Codec an sich ist gut, siehe z.B. Doom9 Codec Vergleich, aber wirklich cool ist er erst in Kombination mit ihrem Java-Applet zum Playback, was leider nicht free ist.

Danke für die Info. 
Hat sich in der Zwischenzeit eigentlich was an der Geschwindigkeit getan? Denn beim letzten Test war VP7 noch arg langsam.

| Zitat: |
A new version of VP7 (v7.0.10.0) is now available from our web site. The main changes are as follows:-
Version 7.0.10.0
=======================================
- Improved overall quality
- Improved speed on best quality mode
- Fixed a problem in one of the blitters that caused
color artifacts for some interlaced clips.
- Fixed a bug that caused spatial re-sampling to crash for some specific
source image sizes and resample ratios.
- Faster first pass encode.
- Improvements in 2 pass rate control.
- Significant changes to the motion search algorithm to improve detection and
tracking in high motion scenes. These changes affect both the first and second pass.
This release removes a previous limitation that prevented the encoder from detecting and tracking motion of greater than 31 ¾ pels. We were keen to address this problem without hurting average encode speed and to this end we have made significant changes to the motion search strategy. As a result, for most of the clips we have tested the new release is actually a little faster.
Obviously the biggest gains are for clips that contain a lot of very high motion. Though this is not very common, there are exceptions and for these the improvement can be dramatic. We have seen some clips where the improvement in overall PSNR was as high as 0.75db and isolated sections where it was much higher.
Even on low motion clips, however, the changes seem to have helped. For example, the HPII trailer previously used by Saggitaire was at the low end of the spectrum but we still saw a small improvement in psnr and an improvement in SSIM ranging from 0.3 at best quality through to about 0.5 at good quality speeds 4&5.
Earlier release notes:
Version 7.0.9.0
=======================================
- fixed bug that produced artifacts in faster speeds ( 2,4,5) when image
size not multiple of 16
- better quality video across wide range of video
- fixed problem in which video offset by 1 pixel when using noise reduction
- improvements to live encoding
Version 7.0.8.0
=======================================
- Improved post processing speed
- added Direct Show Decoder
- added slider which controls how much filtering to do
- added macroblock deblocker
- free for personal use version
- improved quality encode and decode
Version 7.0.7.0
=======================================
- Improved decode speed significantly
- Improved best quality mode
- Improved quality at speed for encode
- solved problem on non intel machines that shut off mmx optimizations of decoder
- solved issue when calling from dshow
- Improved quality of real time encode |
