=== 交错视频滤镜 ===

以下滤镜用于创建和处理基于场格式的视频素材（由于基于帧格式的素材被拆成了场格式而产生的）。虽然AviSynth能处理逐行和交错视频，但主要问题是它经常不能分辨从源滤镜获得视频剪辑的形式。这就是场标志（Field-based Flag）存在并被用于处理交错视频素材的原因。关于场格式视频的更多信息请参见[Interlaced and Field-based video|here]。

=== 音频处理滤镜 ===

These filters can be used to process audio. Audio samples from a clip will be automatically converted if any filters requires a special type of sample. This means that if a filter doesn't support the type of sample it is given, it will automatically convert the samples to something it supports. The internal formats supported in each filter is listed in the sample type column. A specific sample type can be forced by using the [[ConvertAudio]] functions.

If the sample type is float, when AviSynth has to output the data, it will be converted to 16 bit, since float cannot be passed as valid AVI data.
