Add -Size parameter to Crop-Clips.ps1 for custom output resolution with cover-scaling and center-cropping, supporting named presets (320p-4K) that transpose for portrait sources and custom "width:height" format, overriding the cropProfiles table to process videos of any resolution instead of skipping non-standard sizes, with even-number dimension rounding for yuv420p compatibility and skipping of videos already at requested size, plus fix output info reporting to skip when -WhatIf or declined -Confirm leaves

.PARAMETER Target
|
||||
Target directory for cropped video files.
|
||||
.PARAMETER Size
|
||||
Size of the output video. Uses the known non-standard generator resolutions table if not specified.
|
||||
Possible values: 320p, 384p, 480p, 720p, 900p, 1080p, HD, 1440p, 2K, 2160p, 4K, or custom size in format "width:height".
|
||||
When specified, the resolutions table is overridden and every video is scaled (preserving aspect
|
||||
ratio) so it fully covers the requested size, then centre-cropped to it, so videos of any
|
||||
resolution are processed instead of being skipped.
|
||||
Named presets are landscape (e.g. 1080p = 1920x1080) and are transposed for portrait sources
|
||||
(a 1080x1920 source with -Size 1080p stays 1080x1920); a custom "width:height" is used exactly as
|
||||
given. Videos already at the requested size are skipped.
|
||||
.DESCRIPTION
|
||||
Crops video clips to standard resolutions using ffmpeg. Handles the non-standard resolutions
|
||||
produced by LTX-2, Kling and Wan (see the $cropProfiles table), plus any square (1:1) source,
|
||||
which is scaled to 1080x1080. Videos with any other resolution are skipped.
|
||||
which is scaled to 1080x1080. Videos with any other resolution are skipped, unless -Size is
|
||||
used, which overrides the table and converts every video to the requested size.
|
||||
Supports -WhatIf and -Confirm for safe execution.
