Add 320p, 384p, and 900p size presets to Clone-Video.ps1 with aspect-ratio-preserving scaling logic, add -Sideways parameter to Compare-Videos.ps1 for single-row layouts with optional -Clip support, extend -Clip to portrait 2-4 video layouts, and add corresponding crop filters to Crop-Clips.ps1

Path to PNG file for extracted frame. Can be absolute or relative to current directory. .png extension is added if not provided. If EndFrame is -1, extracts the last frame and excludes it from the cloned video. If EndFrame is not -1, extracts the frame at EndFrame index and excludes it from the cloned video.
.PARAMETER Size
Size of the output video. Uses the input video's size if not specified.
Possible values: 480p, 720p, 1080p, HD, 1440p, 2K, 2160p, 4K, or custom size in format "width:height".
Possible values: 320p, 384p, 480p, 720p, 900p, 1080p, HD, 1440p, 2K, 2160p, 4K, or custom size in format "width:height".
For standard named sizes the output preserves the source's aspect ratio: the reference
height is used as the short-side target and the other dimension is computed from the
source AR (landscape/square: target height = reference, width computed; portrait: target
width = reference, height computed). Custom sizes (width:height) are applied exactly.
Forces a video re-encode, since scaling requires re-encoding.
.PARAMETER FPS
Frames per second for the output video. Uses the input video's FPS if not specified.
