Target Options

Video

Use Video

Choose how ProCoder will output video for the target.

Use always

A video track is always output. If the source has no video, a black
video track is generated.

Use if Exist

If the source has video, that video will be output. If the source has
novideo, no video track is generated.

Don’t Use

A video track is not generated, even if the source contains video.

Width

Specifies the width of the output video frame in pixels.

Height

Specifes the height of the output video frame in pixels.

Video Bitrate (kbps)

For non-fixed bitrate codecs, sets the video bitrate in kilobits-per-second. Generally,
the higher the bitrate, the better the video quality is.

Frame rate

Sets the number of frames per second for the output video. The higher the frame rate,
the smoother motion will appear, but the video requires more bits. A good balance
between video frame rate and video bitrate is the key to high-quality playback.

Interlacing

For formats the support interlaced output, this option sets the interlacing mode for
the output. This option determines how video frames are stored in the video stream.
If playback hardware or software does not use the same interlacing method, the video
may not play back smoothly.

Non-Interlaced
(Progressive)

Entire frames are stored in the stream instead of separate fields.

Lower/Bottom Field
First

Frames are stored as separate fields with the lower field first.

Upper/Top Field First

Frames are stored as separate fields with the upper field first.

Aspect Ratio

Sets the aspect ratio of the video image, as width x height, width:height or a width-
to-height ratio for the video frame and/or the display pixels. If available, click the ...
button to select either a video frame aspect ratio or a pixel aspect ratio.
