Pre‑encoding tasks

In general, it’s best to apply certain processing options—such as deinterlacing and cropping—to an exported file prior to encoding it to a particular format. Doing so can avoid visual artifacts associated with performing the same tasks after encoding. The cropping options and deinterlacing options you specify prior to encoding are sometimes referred to as pre‑encoding options.
Note: You can access the Noise Reduction filter option (also considered a pre‑encoding task) by selecting the Filters tab.

Deinterlace the source prior to encoding

 In the Output tab of the Export Settings dialog box, select Deinterlace.

Crop the source prior to encoding

  1. In the Export Settings dialog box, click the Source tab.
  2. Select the Crop button and do any of the following:

    • To crop the image interactively, drag the sides or corner handles of the crop box around the source image.

    • To crop numerically, enter the values for Left, Top, Right, Bottom, in pixels.

    • To constrain the proportion of the cropped image, choose an option from the Crop Proportions menu.

  3. Click the Output tab to preview how the cropped image will appear.
  4. To eliminate black areas resulting from cropping, select Scale to Fit.
    Note: When you actually encode the video, make sure that you set the width and height values in the encoder to match these scale height and width settings. The minimum size to which you can crop an image is 40 pixels by 40 pixels.
