        To convert to HAP-encoded MOV format with no alpha channel for large displays, select the following setting:
             -i "{0}" -c:v hap -format hap -compressor none {5} -y -f mov "{1}"
            • To convert to HAP-encoded MOV format with an alpha channel for large displays, select the following setting:

    • Clear the Strip Audio check box and keep the default option listed in the Audio Options field if audio is required.

    • Select the Scale check box and enter an even number for the Width and Height of the source file resolution. If the display width or height is an uneven number, increase the odd number by adding 1. For example, if the uncompressed AVI file has a width of 3840 and a height of 925, enter the height number as 926.

    • Click OK. The control panel opens again.

    • Click Add/Browse and select the content file(s) to be converted. More than one file can be selected at one time.

    • Click Run. A prompt to delete the original files opens.

    • Click Yes to delete the original uncompressed AVI or MOV files from the computer after the conversion only if a backup exists. If a backup file was not created before the conversion, click No in the dialog box. The files will convert to the new format.

    • Verify that the new MP4 or MOV files are saved in the same folder as the original source files.
