Dv Stream Export Settings; Image Sequence Settings For Quicktime Export; Specify Mpeg-4 Export Settings (Photoshop Extended) - Adobe Photoshop CS6 User Manual

Key Frame Every Specifies the key frame frequency. A higher key frame rate (lower number) improves video quality, but increases the file
size. With some compressors, an additional key frame is inserted automatically if too much of the image has changed from one frame to the
next. In general, one key frame every 5 seconds (multiply the frames per second by 5) is usually sufficient. If you are creating a file for
RTSP streaming and have concerns about the reliability of the delivery network, you may want to increase key frame frequency to one key
frame every 1 or 2 seconds.
Limit Data Rate To Specifies the kilobits per second (kbps) during playback. A higher kbps rate usually improves movie playback quality;
however, don't choose a data rate higher than the available bandwidth.
Depth Specifies the number of colors to include in video that you export. This menu is not available if the selected codec supports only one
color depth.
Quality If available, drag the slider or type a value to adjust the exported video's picture quality and, consequently, its file size. If you are
using the same codec to capture and export, and you've rendered previews of a sequence, you can save rendering time by matching the
export quality setting with your original capture quality setting. Increasing quality above the original capture quality does not increase quality,
but may result in longer rendering times.
Scan Mode Specifies whether the exported movie has fields (Interlaced) or no fields (Progressive).
Aspect Ratio Specifies a 4:3 or 16:9 aspect ratio for the exported movie.
Options (Intel Indeo® Video 4.4 only) Sets compression, transparency options, and access for the Intel Indeo® Video 4.4 codec.

DV Stream export settings

The following options are available in the DV Export Settings dialog box:
DV Format Specifies either the DV or DVCPRO format for your exported video.
Video Format Specifies either NTSC or PAL video broadcast standard.
Scan Mode Specifies whether the exported video has interlaced fields or no fields (Progressive Scan).
Aspect Ratio Specifies an aspect ratio of 4:3 or 16:9.
Preserve Aspect Ratio Using
into the clean aperture, adding black bars to the top and bottom or sides as necessary. Crop centers, scales, and trims to the clean aperture.
Note: Although the DV Export Settings dialog box has Audio Format options, Photoshop Extended does not export audio in DV files.

Image sequence settings for QuickTime export

Typically, QuickTime is used to export video files. However, you can also select Image Sequence from the QuickTime Export pop-up menu. Click
Settings to access the following options:
Format Chooses a file format for the exported images.
Frames Per Second Sets the frame rate for the image sequence.
Insert Space Before Number
Options If available, click the Options button and set format-specific options.

Specify MPEG-4 export settings (Photoshop Extended)

1. In the Render Video dialog box, select QuickTime Export, and choose MPEG-4 from the pop-up menu. Then click Settings.
2. In the MPEG-4 Export Settings dialog box, choose MP4 or MP4 (ISMA) from the File Format menu. The MP4 (ISMA) format ensures
operability with devices made by ISMA members.
3. Under Video, specify the following:
Video Format Chooses the codec to compress your video. For the highest quality at the lowest data rate (or the smallest file), H.264 is
recommended. If you need the file to play on a device that supports MPEG-4 video, choose MPEG-4 Basic or MPEG-4 Improved,
depending on the target device. If your source movie's video track is already compressed, you can choose Pass Through so that the video
doesn't get compressed again.
Data Rate Specifies the kilobits per second (kbps) during playback. A higher kbps rate usually improves movie playback quality; however,
don't choose a data rate higher than the available bandwidth.
Optimized For Specifies how much the data rate can vary above and below the data rate you choose. This option becomes available if you
Specifies an option if the movie is scaled to new pixel dimensions. Letterbox scales the source proportionally to fit
Inserts a space between the name and generated number in the image's filename.
