Functions
- exec(cmd) ⇒
Promise Shells out to execute a command with async/await. Async wrapper to exec module.
- delay(ms) ⇒
Promise Delays process for specified amount of time in milliseconds.
- log()
Log function wrapper that can silences logs when QUIET == true
- zeroPad(i, max) ⇒
string Pads a numerical value with preceding zeros to make strings same length.
- shuffle(a)
Shuffles an array into a random state.
- clear()
Clears the temporary directory of all files. Establishes a directory if none exists.
- frames(video, order, avconv) ⇒
string Exports all frames from video. Appends number to the string to keep frames in alternating order to be quickly stitched together or re-sorted.
- subExec(cmd)
Shells out to run a sub command on every frame to perform effects
- weave(pattern, realtime, random)
Re-arranges the frames into the order specified in the pattern. Calls
patternSort()to perform the rename and unlink actions- altSort(list, pattern, realtime)
Alternate frame sorting method.
- standardSort(list, pattern, realtime)
Standard frame sorting method.
- randomSort(list, pattern, realtime)
Ramdomly sort frames for re-stitching.
- render(output, avconv)
Render the frames into a video using ffmpeg.
- main(arg)
Parses the arguments and runs the process of exporting, sorting and then "weaving" the frames back into a video
