Tips and requirements

Scaling mode. 'stretch' scales the video to the exact target dimensions (may distort aspect ratio). 'pad' scales to fit within the target dimensions while preserving aspect ratio, then pads with the chosen color to fill the remaining space (letterbox/pillarbox). 'crop' scales to cover the target dimensions while preserving aspect ratio, then center-crops to the exact target size.

Padding color when mode is 'pad'. Ignored for other modes.

Video codec to use for encoding. libx264 (H.264) is widely compatible, libx265 (H.265/HEVC) offers better compression.

Encoding speed preset. Slower presets give better compression but take longer.

Constant Rate Factor for quality (0-51). Lower values mean better quality and larger files. 18 is visually lossless for most content.

How to use Workflow Utilities Scale Video

Getting started

Resize an existing video for a different layout. Choose whether to retain the whole frame, crop the edges or stretch the image.

Review your result

Play the resized export. Check subject framing, distorted proportions and visible compression; resizing alone does not restore missing detail.

Inputs and settings

Provide video_url and at least width or height, using even pixel dimensions. One dimension preserves the aspect ratio; two dimensions use mode.

pad retains the frame with borders; crop fills the frame by center-cropping; stretch may distort proportions. Select codec, preset and crf for encoding.
