After a long testing and debugging period, we are now ready to present the AviSynth 2.5.0 beta. A big thanks to everyone here - the testers - the patient developers - and those spreading the word of AviSynth!
We have some great features under the hood of the new AviSynth that hopefully will be able to bring non-linear video editing to a new level! (ok - enough with the rants).
The summed up changes:
* Native planar YV12 support.
* Multiple audiochannels. Unlimited number of channels is now supported.
* Float samples support. AviSynth is now capable of processing samples as floats.
* Automatic sample conversion. If some filters doesn't support a specific sample type, they are converted to the format preserving most quality.
* Optimizations. Many basic features has been optimized, and now performs much better than previous versions.
* Temporalsoften has a significant speed improvement, scenechange detection and a new improved blend mode.
* Limiter can limit the YUV ranges, to avoid invalid color values and improve compression.
* ColorYUV makes it possible to do very exact color corrections. ColorYUV has built-in auto-whitebalance and auto-gain features.
* Select separate planes using UToY, VToY and merge them together again, using YToUV.
* Fliphorizontal. implemented.
* SelectRangeEvery is now part of the core functions.
* Blur, Sharpen, Resize optimized.
* Fast XviD colorspace conversions.
* Updated installer.
* AviSynth icons.
* See clip info using the info() command.
... and many more internal changes!
A rather complete changelog can be found here.
... but we are still in Beta so here are some of the issues we are still dealing with:
Known issues are:
- Stackvertical can give strange results at some resolutions. Use resolutions that are multiples of 16.
- Temporalsoften can still act strange in rare cases. Try moving it to a different location in the filter chain.
- Some filters, in a certain order may produce problems. Try moving your filters around, or look for updates.
As usual the package can be downloaded from SourceForge. Use the Minneapolis mirror - they do not all seem to be updated.
Since all filters have to be updated, there has been collected a package of some of the basic plugins used for AviSynth. This can also be downloaded from the URL above.
Test away - and report any problem at doom9.org forums or at SourceForge!
