各チャンネル16-bitのサポートはAviSynth v3.0から †

• Doom9's Forum - 16bit per channel Avisynth（Wilbert氏の発言を引用）

  quote:

  Are there any plans to make Avisynth support 16 bit per channel, or perhaps even float? In RGB.

  Yup, in AviSynth v3.0. Why float though?

Planar YUY2とWin64に対応したAviSynthの可能性 †

• Doom9's Forum - Planar YUY2. Will it be supported?（sh0dan氏の発言を引用）

  Adding 4:2:2 and 4:4:4 planar support to 2.5 would be possible, but it would also increase filter complexity. I'd personally rather see a AviSynth moved to Win64 - and the new planar modes could be added in the process.

SSEToolsに含まれるdifferenceフィルタ †

• kassandro氏のSSEToolsプラグインには、differenceという名前のフィルタも収録されているらしい。
• differenceフィルタとは？
  • Doom9's Forum - chroma denoising

    You can monitor the agressiveness of a filter nicely with the difference filter contained in SSETools:

• 書式1

  difference(filtered, unfiltered)

• 書式2

  difference(filtered, unfiltered, tolerance=5) # ignores all difference <= 5

• 動作にはdebugview utilityが必要？

  Then the SAD difference and the number of different pixels is reported to the debugview utility

• debugview utilityとは？
  • Sysinternals Freeware - Utilities for Windows NT and Windows 2000 - DebugView

    DebugView is an application that lets you monitor debug output on your local system, or any computer on the network that you can reach via TCP/IP.
