Interlace filters

These filters can be used for creating and processing field-based material (which is frame-based material separated into fields). AviSynth is capable of dealing with both progressive and interlaced material. The main problem is, that it often doesn't know what it receives from source filters. This is the reason that the field-based flag exists and can be used when dealing with interlaced material. More information about field-based video can be found here.

Audio processing filters

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.

滤镜 简介 Sample type
Amplify / AmplifydB Amplify multiply audio samples by amount. 16 bit, Float
AssumeSampleRate Adjusts the playback speed of the audio. All
AudioDub / AudioDubEx AudioDub takes the video stream from the first argument and the audio stream from the second argument and combines them. AudioDubEx is similar, but it doesn't throw an exception if both clips don't have a video or audio stream. All

TimeStretch This filter can change speed of the sound without changing the pitch, and change the pitch of a sound without changing the length of a sound. Float

Conditional and other meta filters

Meta filters can be used to control other filters execution. The basic characteristic of conditional filters is that 'their scripts' are evaluated (executed) at every frame instead of the whole clip. This allows for complex video processing that would be difficult or impossible to be performed by a normal AviSynth script.

滤镜 简介 颜色空间
ConditionalFilter / FrameEvaluate / ScriptClip ConditionalFilter returns source1 if some condition is met, otherwise it returns source2. ScriptClip/FrameEvaluate returns the clip which is returned by the function evaluated on every frame. YUY2 ?, YV12
ConditionalReader ConditionalReader allows you to import information from a text file, with different values for each frame - or a range of frames. YUY2 ?, YV12

Animate / ApplyRange Animate (ApplyRange) is a meta-filter which evaluates its parameter filter with continuously varying (the same) arguments. RGB24, RGB32, YUY2, Y8, YV411, YV12, YV16, YV24 ?
