Adding Frame Controls, Geometry, and Actions to a Setting
Note: If you want to transcode a normal size standard definition (SD) source media
file (720 x 486) using an MPEG-2 NTSC setting, your output media file will be
automatically cropped (two pixels from the top and four from the bottom) to achieve
the MPEG-2 required dimensions of 720 x 480, unless you already specified cropping
attributes. This crop attribute is only temporary and is not saved in the setting. You
can see the automatic crop in the usual way, by double-clicking the setting in the
Batch table to open the Preview window.
See “
” on page 129 for more information about the
Video Format pop-up menu.
 “Pixel aspect” pop-up menu: Forces the pixel aspect ratios to conform to specific
formats. This is especially important when using some filters. For example, if the
graphic you use for the Watermark filter uses a circle and you want to be sure it still
looks like a circle when finished (as opposed to an oval), you must choose the “Pixel
aspect” setting that matches your output format. Options include:
 Default: The pixel aspect ratio is not changed.
 Square: Use this when the output is to be displayed on computers.
 NTSC CCIR 601/DV: Forces the pixel aspect ratio to 4:3 using 720 x 480 pixels.
 NTSC CCIR 601/DV (Anamorphic): Forces the pixel aspect ratio to 16:9 using
720 x 480 pixels.
 PAL CCIR 601: Forces the pixel aspect ratio to 4:3 using 720 x 576 pixels.
 PAL CCIR 601 (Anamorphic): Forces the pixel aspect ratio to 16:9 using 720 x 576 pixels.
 DVCPRO HD 720p60 (16:9): Forces the pixel aspect ratio to 16:9 using 1280 x 720 pixels.
 DVCPRO HD 1080i60 (16:9): Forces the pixel aspect ratio to 16:9 using
1920 x 1080 pixels.
 HDV 1080i (16:9): Forces the pixel aspect ratio to 16:9 using 1440 x 1080 pixels.
 “Constrain to display aspect” pop-up menu: Forces the entered output size width and
height values to conform to a designated aspect ratio. You can leave it at the default of
None, or set it to either 4:3, 16:9, or 2.35:1. If you choose anything other than None, and
enter either a Width or a Height value, the other value will be calculated automatically.
