Output settings
Target size is best effort: the editor may reduce width and frame rate to approach it, which can affect detail and smoothness. Processing uses this device's memory; start with a short trim and check the measured output size.
Drag on the preview to select a crop area. Fine-tune it with the crop fields.
Add a timed caption
Caption processing stays on this device. Limited to 150 frames and 24 megapixels of total frame data.
