)

Arguments

type: string: the layer type (e.g. "title", "image", "video")
...: : other parameters
duration: numeric: duration in seconds
transition: list: an er_transition() object
layers: list: a list of er_layer objects
layer: list: default layer spec
layer_type: list: default layerType spec
out_path: string: the path of the video file to create (the file extension can be a video file extension or ".gif")
fps: numeric: frames per second (default = 25 or FPS of first video)
width: integer: video width (default = 640)
height: integer: auto based on width and aspect ratio of first video
allow_remote_requests: logical: allow remote URLs as paths? (default = FALSE)
audio_file_path: string: set an audio track for the whole video
loop_audio: logical: loop the audio track if it is shorter than video? (default = FALSE)
keep_source_audio: logical: keep source audio from clips? (default = FALSE)
clips_audio_volume: numeric: volume of audio from clips relative to er_audio_track()s (default = 1)
output_volume: numeric or string: adjust output volume (final stage). e.g. 0.5 or "10dB" (default = 1)
audio_norm.enable: logical: enable audio normalization? (default = FALSE)
audio_norm.gauss_size: numeric: audio normalization gauss size (default = 5)
audio_norm.max_gain: numeric: audio normalization max gain (default = 30)
defaults: er_defaults: as returned by er_defaults()
custom_output_args: character: vector of custom output codec/format arguments for ffmpeg
logo_path: string: path to logo file. This must be a local file, even if allow_remote_requests is TRUE. logo_path will be ignored if out_path is a gif
logo_width: numeric: width of logo relative to screen width (0 to 1, default = 0.2). If only one of logo height or width is specified, the logo aspect ratio will be retained
logo_height: numeric: height of logo relative to screen width (0 to 1, default = 0.1). If only one of logo height or width is specified, the logo aspect ratio will be retained
logo_x: numeric: logo left-hand-edge position relative to left of screen (0 = left to 1 = right, default = 0.78). The logo is referenced relative to its left-hand edge, so the default of 0.78 and width 0.2 puts the right-hand edge at 0.98
logo_y: numeric: logo bottom-edge position relative to top of screen (0 = top to 1 = bottom, default = 0.98)

Value

A list with class er_clip, er_layer, etc
