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 :doc:`script variables ` (see the :doc:`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 :doc:`here[1] <../corefilters/fps>`. - 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). - IsPlanarRGB (clip) Returns true if the clip is planar RGB, false otherwise (type: bool). - IsPlanarRGBA (clip) Returns true if the clip is planar RGBA, 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). - IsRGB48 (clip) (Avisynth+) Returns true if the clip is RGB48, false otherwise (type: bool). - IsRGB64 (clip) (Avisynth+) Returns true if the clip is RGB64, false otherwise (type: bool). - IsYUV (clip) (v2.54) Returns true if the clip is `YUV`_, false otherwise (type: bool). - IsYUVA (clip) (Avisynth+) Returns true if the clip is YUVA (YUV + alpha channel), false otherwise (type: bool). - IsY8 (clip) (2.60) Returns true if the clip is `Y8`_, false otherwise (type: bool). - IsY (clip) (Avisynth+) Returns true if the clip is Y (like Y8, but bit depth independent) grey scale, 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). - Is420 (clip) (Avisynth+) Returns true if the clip is 4:2:0 (like IsYV12, but bit depth independently), false otherwise (type: bool). - IsYV16 (clip) (v2.60) Returns true if the clip is `YV16`_, false otherwise (type: bool). - Is422 (clip) (Avisynth+) Returns true if the clip is 4:2:2 (like Is YV16, but bit depth independently), false otherwise (type: bool). - IsYV24 (clip) (v2.60) Returns true if the clip is `YV24`_, false otherwise (type: bool). - Is444 (clip) (Avisynth+) Returns true if the clip is 4:4:4 (like IsYV24, but bit depth independently), 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 :doc:`here[2] <../advancedtopics/interlaced_fieldbased>`. - IsFrameBased (clip) Returns true if the clip is frame-based (type: bool). What this means is explained :doc:`here[2] <../advancedtopics/interlaced_fieldbased>`. - 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). - HasVideo (clip) (v2.56) Returns true if the clip has video, false otherwise (type: bool). - ComponentSize (clip) (Avisynth+) Returns 1 for 8 bit, 2 for 10-16 bits, 4 for 32 bit float pixel formats (type: int). - BitsPerComponent (clip) (Avisynth+) Returns 8, 10, 12, 14, 16 or 32: the actual bit depth of the video format (type: int). - NumComponents (clip) (Avisynth+) Returns 1 for greyscale, 3 for alpha-less RGB and YUV formats, 4 for formats with alpha channel: YUVA, planar RGBA, RGB32 or RGB64 (type: int). - HasAlpha (clip) (Avisynth+) Returns true if video format has alpha channel (type: bool). - IsPackedRGB (clip) (Avisynth+) Returns true if video format is one of the packed (not planar) RGB formats: RGB24, RGB32, RGB48 or RGB64 (type: bool). - IsChannelMaskKnown (clip) (Avisynth+ v3.7.3) Returns true if the clip has audio channel mask defined (type: bool). - GetChannelMask (clip) (Avisynth+ v3.7.3) Returns the channel mask (a 32 bit number), if audio channel mask is defined, 0 otherwise.
