Modern HD formats nearly always use square pixels,but if you wish to export using non-square pixels, you can set the aspect ratio here. Aspect Ratio: sets the aspect ratio of individual pixels in your exported file.You can deselect the From Source option and manually select a frame rate, but keep in mind that changing the frame rate will affect the speed at which the video in the exported file plays back. Frame Rate: This defaults to From Source, so the frame rate of whatever timeline you are exporting will be used, and should generally be left there.Keep Aspect Ratio by Expanding will increase the scale of the source timeline as required to fill the export resolution, which may result in some cropping of the source timeline.Ignore Aspect Ratio will warp the source timeline to fit the size and shape of the export resolution.If your source is smaller than the export resolution, black edges will be added. If the source is larger than your export resolution, it will be cropped to fit. Center will center the source timeline into the export resolution, without scaling.Keep Aspect Ratio is the default, and prevents the frame from being distorted if the export resolution uses a different aspect ratio from the timeline.Scale Mode: This menu lets you control how the timeline is fitted into the exported frame.You can also tick the box under “From Source” to have the preset automatically use the dimensions of the timeline being exported. By default these will be set to the dimensions of the selected timeline. Width / Height: Set the dimensions at which the timeline will be exported.Codec: MP4 export requires the use of the H.264 codec, so this setting cannot be edited.Comment: You may add a comment to your preset, to remind you of details of the compression, or when the preset is intended to be used, or other information.This option is selected from the New menu at the bottom of the panel, before the preset is made, and cannot be edited here. Format: The format used by the preset.This is the name that will be shown in the Presets panel of the Export screen.
