The available (internal) filters are listed here and divided into categories. A short description is added, including the supported [[Color_spaces|color formats]] (and sample types for the audio filters). There are some functions which combine two or more clips in different ways. How the video content is calculated is described for each function, but [[filters_with_multiple_input_clips|here is a summary which explains which properties that the resulting clip will have]].
这里列出了AviSynth2.5中的核心滤镜,按照他们的功能进行了分类,并附有简介和他们所支持的[[ 颜色空间]] (音频滤镜附有其支持的采样类型)。其中一部分滤镜可以将两个(或更多)剪辑进行不同方式的组合,简介中分别描述了他们各自处理剪辑的方式,您也可以[[ 多剪辑滤镜| 参考这里看看他们之间的对比]]


An alphabetical listing of the internal filters can be found here [[:Category:Internal_filters]]. '''Note that (as of today) there is no official build of v2.60 yet.'''

=== Media file filters ===
=== 媒体文件滤镜 ===


These filters can be used to read or write media files. Usually they produce source clips for processing. See debug filters for non-file source filters.
媒体文件滤镜可以用过来读/写媒体文件。他们可以用来创建原始剪辑。要了解不通过文件创建原始剪辑的滤镜,请参见调试用滤镜。

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.

PeculiarBlend This filter blends each frame with the following frame in a peculiar way. YUY2
Pulldown This filter simply selects two out of every five frames of the source video. RGB24, RGB32, YUY2, Y8, YV411, YV12, YV16, YV24

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
ConvertAudioTo8bit / ConvertAudioTo16bit / ConvertAudioTo24bit / ConvertAudioTo32bit / ConvertAudioToFloat Converts audio samples to 8/16/24/32/Float bits. All
ConvertToMono Merges all audio channels. 16 bit, Float
DelayAudio Delays the audio track by second seconds. All
EnsureVBRMP3Sync Corrects out-of-sync MP3-AVI's, when seeking or trimming. All
GetChannel / GetLeftChannel / GetRightChannel Returns an audio channel from a clip. All
KillAudio / KillVideo Removes the audio or video from a clip completely. All
MergeChannels Merges channels of two audio clips. All
MixAudio Mixes audio from two clips. 16 bit, Float
MonoToStereo Converts two mono signals to one stereo signal. 16 bit, Float
Normalize Amplifies the entire waveform as much as possible, without clipping. 16 bit, Float
ResampleAudio Performs a high-quality change of audio sample rate. 16 bit
SuperEQ High quality 16 band sound equalizer. Float
SSRC Very high quality samplerate conversion. Float
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
WriteFile / WriteFileIf / WriteFileStart / WriteFileEnd These filters evaluate expressions and output the results to a text-file. RGB24, RGB32, YUY2, Y8, YV411, YV12, YV16, YV24 ?
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 ?
TCPServer / TCPSource This filter will enable you to send clips over your network. You can connect several clients to the same machine. RGB24, RGB32, YUY2, Y8, YV411, YV12, YV16, YV24

Debug filters
