Description
Inspired by AudioGraph, waveform is a plugin to overlay audio waveforms on video clips - useful for identifying sync issues and audio glitches.
Improvements over AudioGraph are:
- A nicer, variable height overlay
- Separate graphs for each channel, works with an arbitrary number of channels
- Works with YV12 video, as well as RGB24/RGB32/YUY2
- Audio format is passed through unchanged
Requirements
Syntax and Parameters
- waveform (clip, int "window", float "height", bool "under", float "zoom", bool "marks")
- clip =
- Input clip; must contain audio and video.
- clip =
- int window = 1
- The number of frames either side to display a waveform for (default: 1).
- int window = 1
- float height = 0.333
- >=1 : height in pixels of each audio channel displayed
- <1 : total height of waveform display as a fraction of video height (default: 0.333)
- float height = 0.333
- bool under = false
- If true, display the waveform underneath the video instead of superimposed on it (default: false).
- bool under = false
- float zoom = 1.0
- Scale up the waveform.
- float zoom = 1.0
- bool marks = true
- Display frame boundary marks (default: true).
- bool marks = true
Examples
waveform with default values:
AviSource("blah.avi") # make sure clip has audio and video waveform(window=1, height=0.333, under=false, zoom=1.0, marks=true)
Changelog
Version Date Changes
v0.3 2015/02/28 - new parameter: "marks" - mitigate crash when "window" is set to high values
v0.2 2012/10/06 - commented out the function which uses vsprintf_s - hopefully fixed those rowsize/pitch issues (but only for YV12/YUY2 so far)
v0.2 2012/08/19 - initial release
