# Format Tab

Use the Format Settings options to perform any resizing, including resize filter options.

Width / Height
  Enter the desired resize settings.
Fit/Stretch
  To use a different aspect ratio during resize, select a fit method option to be applied to the exported clip.

Select: | To:
--- | ---
Centre/Crop | Fit the source image, centred, over the destination frame. If the source is larger than the destination, it is cropped. If the source is smaller than the destination, it is surrounded by a black border.
Crop Edges | Fit one edge of the source into the destination frame without stretching or squashing the frame. Excess parts of the source frame after resizing are cropped. If the source—after the one edge is resized—is wider than the destination, its overhanging left and right edges are cropped. If the source is taller than the destination, the upper and lower edges are cropped.
Fill | Fit the source, width and height, into the destination frame. If the source and destination frames do not have the same aspect ratio, the image can become distorted.
Letterbox | Fit the source to the destination frame without squashing or stretching it, and without cropping the source. If the source is wider than the destination, black bars fill the top and bottom of the destination frame. If the source is narrower than the destination, black bars fill the right and left sides of the frame. In all cases, the entire source frame is contained within the destination frame.

Filter
  Select the filter option to determine the quality of the interpolated resize result.

Select: | To get:
--- | ---
Impulse | Quick, low-quality results.
Triangle | Moderate results with little processing overhead.
Mitchell | Best results when resizing a clip to a higher resolution.
Bicubic | Very good results for resizing soft-looking images. Use to sharpen the image.
Quadratic | Good results for resizing simple images with straight edges. Similar to Gaussian but with more blurring. Use to soften the image.
Gaussian | Excellent results when resizing a clip with no patterns and a lot of straight edges to a lower resolution. Useful for softening some detail.
Shannon | Excellent results when resizing a clip to a lower resolution. Very similar to Lanczos, but results are a little softer.
Lanczos | Best results when resizing a clip containing a variety of patterns and elements to a lower resolution. It is the most complex with the longest processing time.
