## AviSynth Clip properties

You can access clip properties in AVS scripts. For example, if the variable clip holds a video clip, then clip.height is its height in pixels, clip.framecount is its length in frames, and so on. Clip properties can be manipulated just like script variables (see the AviSynth Syntax for more), except that they cannot be l-values in C-terminology.

The full list of properties:

- Width (clip)

  Returns the width of the clip in pixels (type: int).

- Height (clip)

  Returns the height of the clip in pixels (type: int).

- FrameCount (clip)

  Returns the number of frames of the clip (type: int).

- FrameRate (clip)

  Returns the number of frames per seconds of the clip (type: float). The framerate is internally stored as a ratio though and more about it can be read here.

- FrameRateNumerator (clip) (v2.55)

> Returns the numerator of the number of frames per seconds of the clip (type: int).

- FrameRateDenominator (clip) (v2.55)

> Returns the denominator of the number of frames per seconds of the clip (type: int).

- AudioRate (clip)

  Returns the sample rate of the audio of the clip (type: int).

- AudioLength (clip) (v2.51)

  Returns the number of samples of the audio of the clip (type: int). Be aware of possible overflow on very long clips (2^31 samples limit).

- AudioLengthLo (clip [, int]) (v2.60)

  Returns the number of samples of the audio of the clip modulo int. int is 1,000,000,000 by default (type: int).

- AudioLengthHi (clip [, int]) (v2.60)

  Returns the number of samples of the audio of the clip divided by int (truncated to nearest integer). int is 1,000,000,000 by default (type: int).

- AudioLengthS (clip) (v2.60)

  Returns a string formated with the total number of samples of the audio of the clip (type: string).

- AudioLengthF (clip) (v2.55)

  Returns the number of samples of the audio of the clip (type: float).

- AudioDuration (clip) (v2.60)

  Returns the duration in seconds of the audio of the clip (type: float).

- AudioChannels (clip)

  Returns the number of audio channels of the clip (type: int).

- AudioBits (clip)

  Returns the audio bit depth of the clip (type: int).

- IsAudioFloat (clip) (v2.55)

  Returns true if the audio format of the clip is float (type: bool).

- IsAudioInt (clip) (v2.55)

  Returns true if the audio format of the clip is an integer type (type: bool).

- IsRGB (clip)

  Returns true if the clip is RGB, false otherwise (type: bool).

- IsRGB24 (clip) (v2.07)

  Returns true if the clip is RGB24, false otherwise (type: bool).

- IsRGB32 (clip) (v2.07)

  Returns true if the clip is RGB32, false otherwise (type: bool).

- IsYUV (clip) (v2.54)

  Returns true if the clip is YUV, false otherwise (type: bool).

- IsY8 (clip) (2.60)

  Returns true if the clip is Y8, false otherwise (type: bool).

- IsYUY2 (clip)

  Returns true if the clip is YUY2, false otherwise (type: bool).

- IsYV12 (clip) (v2.52)

  Returns true if the clip is YV12, false otherwise (type: bool).

- IsYV16 (clip) (v2.60)

  Returns true if the clip is YV16, false otherwise (type: bool).

- IsYV24 (clip) (v2.60)

  Returns true if the clip is YV24, false otherwise (type: bool).

- IsYV411 (clip) (v2.60)

  Returns true if the clip is YV411, false otherwise (type: bool).

- PixelType (clip) (v2.60)

  Returns the name of the pixel format (type: string).

- IsFieldBased (clip)

> Returns true if the clip is field-based (type: bool). What this means is explained here.

- IsFrameBased (clip)

> Returns true if the clip is frame-based (type: bool). What this means is explained here.

- IsPlanar (clip) (v2.52)

  Returns true if the clip is planar, false otherwise (type: bool).

- IsInterleaved (clip) (v2.52)

  Returns true if the clip color format is Interleaved, false otherwise (type: bool).

- GetParity (clip, int n)

  Returns true if frame n (default 0) is top field of field-based clip, or it is full frame with top field first of frame-based clip (type: bool).

- HasAudio (clip) (v2.56)

  Returns true if the clip has audio, false otherwise (type: bool).

- HasVideo (clip) (v2.56)

  Returns true if the clip has video, false otherwise (type: bool).
