position can be one of either:
top, bottom center, top-left, top-right, center-left, center-right, bottom-left, bottom-right
a list object
list(x = x, y = y, originX = "left", originY = "top"), where(x = 0, y = 0)is the upper left corner of the screen, and(x = 1, y = 1)is the lower right corner, x is relative to video width, y to video height. originX and originY are optional, and specify the position's origin (anchor position) of the object.

Details
Audio layers will be mixed together. If cutFrom/cutTo is set, the resulting segment (cutTo-cutFrom) will be slowed/sped-up to fit clip.duration. The slow down/speed-up operation is limited to values between 0.5x and 100x.
er_layer_detached_audio is a special case of audio_tracks that makes it easier to start the audio relative to clips start times without having to calculate global start times. detached audio has the exact same properties as audio_tracks, except start time is relative to the clip's start.
For video layers, if parent clip.duration is specified, the video will be slowed/sped-up to match clip.duration. If cutFrom/cutTo is set, the resulting segment (cutTo-cutFrom) will be slowed/sped-up to fit clip.duration. If the layer has audio, it will be kept (and mixed with other audio layers if present.)
resize_mode - How to fit image to screen. Can be one of:
"contain" - All the video will be contained within the frame and letterboxed
"contain-blur" - Like contain, but with a blurred copy as the letterbox
"cover" - Video be cropped to cover the whole screen (aspect ratio preserved)
"stretch" - Video will be stretched to cover the whole screen (aspect ratio ignored). Default is "contain-blur".
