Resizing from Source Using the Crop Box

Using the more complete resize settings in Resize, Resize nodes in Batch, or in the Resize soft effect, you can set or animate the position and size of the crop box and have a dynamic preview from which to view results while setting the resize settings.

You can resize the entire source frame to the destination resolution using the Fill and Letterbox fit methods:

- The Fill fit method produces the best results when the source and destination resolutions are the same aspect ratio, such as when resizing from NTSC to PAL, or from any of the 4:3 full-aperture flat film formats (2048x1536) to NTSC/PAL.
- The Letterbox fit method is good for resizing a 16:9 clip to a 4:3 clip without losing any of the 16:9 original.

To resize a clip using the Fill fit method:

1. Access the Resize module for a clip on the Desktop, in Batch, or from soft effects if you are working on the timeline.
2. To fit the entire source frame into the destination frame, the crop box must be the same size as the source frame and aligned along its edges. Do one of the following:
   - In the Width and Height fields, enter the source frame resolution values. Make sure the crop box is centred over the front clip.
   - Click the Source button next to the Clip label to match the crop box width and height to the source clip.
3. From the Resolution Presets box, select the destination resolution. You can also select Custom and then enter width and height values in the W and H fields.

   The destination resolution should be the same aspect ratio as the source. If not, the resize process (using the Fill fit method) will stretch or squash the clip.

   NoteYou are not able to define the output resolution in the Soft Resize menu. The output resolution is determined by the project's resolution.
4. From the Fit Method box, select Fill to fit the source, width, and height to the destination resolution.
5. From the Filter box, select a filter option.
6. Depending on the source and destination resolutions, select a scan mode from the Scan Mode box.
7. Process the result.

To resize a 16:9 source clip to a 4:3 destination resolution using the Letterbox fit method:

1. Access the Resize module for a 16:9 clip on the Desktop, in Batch, or from soft effects if you are working on the timeline.
2. Click the Source button next to the Clip label to make the crop box the same size as the source frame.
3. From the Resolution Presets box, select a 4:3 destination resolution. You can also set custom width and height in the W and H fields.
4. From the Fit Method box, select Letterbox.

   Black bars appear above and below the source frame, which itself is resized to fit the destination frame.

5. From the Filter box, select a filter option.
6. Depending on the source and destination resolutions, select a scan mode from the Scan Mode box.
7. Process the result.
