video-aspect-cropper

Video Crop Rotate and Aspect Reframer is a desktop video geometry editor and aspect
ratio converter for Linux powered by bundled FFmpeg.
A lightweight Linux alternative to desktop HD video crop and aspect conversion tools,
it converts widescreen, vertical, square, portrait, and ultrawide videos with live
rendered frame previews.

Key Features:
- Social & Cinema Aspect Presets: Convert between 9:16 Vertical, 1:1 Square,
4:5 Portrait, 16:9 Widescreen, 21:9 Cinema, or any custom pixel crop rectangle.
- Blurred Background Fill (boxblur) & Solid Pad: Convert landscape clips into
vertical or square frames with soft blurred background fill, solid color letterboxing
and pillarboxing, or pan-offset smart center cropping.
- Geometry Rotation & Mirroring: Apply 90, 180, or 270 degree rotation alongside
horizontal and vertical video flips in a single filter pass.
- Live Rendered Frame Preview & Batch Queue: Preview exact FFmpeg filter output frames
at any timeline timestamp, batch-export multi-aspect packs, and inspect output streams.
