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]].

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.

{{AvsPluscon}} automatic conversion is ''not'' performed. The new behavior is to raise an error when a sample type is not compatible. It is your responsibility to use [[ConvertAudio]] where needed.
  
−
{| style="height:100px" border="1" cellpadding="4"
+
[[Float]] audio is converted to 16 bit when [[Frameserver|frameserving]] through [[ACM]], unless [[Internal_functions#OPT_AllowFloatAudio|OPT_AllowFloatAudio]] is set to true. In that case the audio is kept as it is. When accessing AviSynth directly (like MeGUI, BeHappy or ffmpeg do for example), there is no automatic conversion.
 +
 
 +
The automatic conversion is done for clients that cannot handle [[Float]] audio (in the old days most of them couldn't). Note conversion takes place ''after'' the script processing is finished. [[Float]] audio is always allowed within the script.

The available (internal) filters are listed here and divided into categories. A short description is added, including the supported 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 here is a summary which explains which properties that the resulting clip will have.

An alphabetical listing of the internal filters can be found here.

Contents

FixBrokenChromaUpsampling The free Canopus DV Codec v1.00 upsamples the chroma channels incorrectly (although newer non-free versions appear to work fine). This filter compensates for it. YUY2

[edit] Timeline editing filters

These filters can be used to arrange frames in time (clip cutting, splicing and other editing).

Filter Description Color format
AlignedSplice / UnalignedSplice Joins two or more video clips end to end. All
AssumeFPS / AssumeScaledFPS / ChangeFPS / ConvertFPS Changes framerate and/or video speed in different ways. All

[edit] 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.

Filter Description Color format
AssumeFrameBased / AssumeFieldBased Forces frame-based or field-based material. All
AssumeBFF / AssumeTFF Forces field order. All

SeparateFields Splits each frame into its component top and bottom fields. All
SwapFields Swaps the two fields in an interlaced frame. All
Weave Combines fields together to produce interlaced frames. All
WeaveColumns / WeaveRows Takes a clip and weaves sets of columns or rows together to produce composite frames. All

[edit] Audio processing filters

These filters process audio. Audio samples 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.

AVS+ automatic conversion is not performed. The new behavior is to raise an error when a sample type is not compatible. It is your responsibility to use ConvertAudio where needed.

Float audio is converted to 16 bit when frameserving through ACM, unless OPT_AllowFloatAudio is set to true. In that case the audio is kept as it is. When accessing AviSynth directly (like MeGUI, BeHappy or ffmpeg do for example), there is no automatic conversion.

The automatic conversion is done for clients that cannot handle Float audio (in the old days most of them couldn't). Note conversion takes place after the script processing is finished. Float audio is always allowed within the script.

Filter Description 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
AudioTrim Trims an audio clip so that it includes only the start_time through end_time. 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, Float
SuperEQ High quality 18 band sound equalizer. Float
SSRC Very high quality sample rate conversion. Float
TimeStretch Change speed of a sound without changing the pitch, and change pitch without changing duration. Float

[edit] 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 when the clip is loaded. This allows for complex video processing that would be difficult or impossible to be performed by a normal AviSynth script.

Filter Description Color format
ConditionalFilter / FrameEvaluate / ScriptClip / ConditionalSelect 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. ConditionalSelect returns one frame from several sources based on an integer evaluator. All
ConditionalReader Import information from a text file, with different values for each frame - or a range of frames. All
WriteFile / WriteFileIf / WriteFileStart / WriteFileEnd These filters evaluate expressions and output the results to a text-file. All
Animate / ApplyRange Animate is a meta-filter which evaluates another filter with continuously varying arguments.

ApplyRange 'is a special case of Animate where start_args = end_args.

All
TCPServer / TCPSource Send clips over your network. You can connect several clients to the same machine. All

[edit] Export filters

These filters can write directly to media files.

Filter Description Color format
ImageWriter Writes frames as images to your hard disk. See ImageReader. All
