Official AviSynth 2.5.0 beta

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, not all mirrors are 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 here or at SourceForge!

Time to play now - thanks to everyone whoes worked on it

Besides slim and none, what are the odds of audio support for DirectShow?

I think we're all for it, all we need is someone who knows how to program DirectX.

Affirmative! It's gone - there is still some strangeness in rare situations, but it's perfectly safe to use in encodes!


@All: Thanks for the kind words! Now let's get the last problems squished!

Thank you, but in all honesty I've had very little to do with 2.5 (time issues, plus the fact I don't have any YV12 sources). That won't be the case for 3.0

Most other sources - MPEG2, MJPEG, MPEG4 are all in YV12. Most destination formats MPEG1, MPEG2, MPEG4 are YV12 based (though not all encoders handle YV12 that well) That's what the fuss is about.

I think you have to use mpeg2dec3.dll.
