3. Click the Select Folder button, and navigate to the location for the exported files.
To create a folder to contain your exported file, select the Create New Subfolder option and enter a name for the subfolder.
4. Under File Options, select either QuickTime Export or Image Sequence. Then choose a file format from the pop-up menu.
5. (Optional) Click Settings to specify format-specific options.
6. (Optional) If you chose Image Sequence in step 4, specify the Starting and Digits numbers. (These options specify the numbering system for
the exported files.) Use the Size pop-up menu to specify the pixel dimensions for the exported files.
7. Under Range, select one of the following options:
All Frames Renders all the frames in the Photoshop document.
In Frame and Out Frame
Currently Selected Frames
8. (Optional) Specify render options:
Alpha Channel Specifies how alpha channels are rendered. (This option is available only with formats that support alpha channels, such as
PSD or TIFF). Select None to ignore the alpha channel, Straight-Unmatted to include the channel, or one of the Premultiplied options to mix
a matte color with the color channels.
Frame Rate Determines how many frames are created for each second of the video or animation. The Document Frame Rate option
reflects the rate in Photoshop. If you're exporting to a different video standard (from NTSC to PAL, for example), choose the appropriate rate
from the pop-up menu.
9. Click Render.
QuickTime export file formats
3G A file format developed for third-generation mobile devices.
FLC An animation format for playback of computer-generated animations on workstations, Windows, and Mac OS. This format is also referred to
as FLI.
Flash Video (FLV) Adobe® Flash® Video is the Adobe format for streaming audio and video over the web and other networks. (To use this
format, you must first install an FLV QuickTime encoder).
QuickTime Movie The Apple Computer multimedia architecture that includes a number of codecs. (To export audio, you must use this format.)
AVI Audio Video Interleave (AVI) is a standard format for audio and video data on Windows computers.
DV Stream A video format with intraframe compression that uses FireWire (IEEE 1394) interface to transfer video to nonlinear editing systems.
Image Sequence A sequence of still images that can reside within one folder and use the same numeric or alphabetic filename pattern (such as
Sequence1, Sequence2, Sequence3, and so forth).
MPEG-4 A multimedia standard for delivering audio and video streams over a range of bandwidths.
Note: Photoshop also supports other third-party formats such as Avid AVR codecs; however, the necessary QuickTime codecs must be installed.
Understanding QuickTime key frames
In QuickTime terminology, the term key frames refers to something different than the animation keyframes in Photoshop. In QuickTime, key frames
occur at regular intervals in the movie and are stored as complete frames. Each intermediate frame that separates them is compared to the
previous frame, and only changed data is stored. Using key frames greatly reduces movie size and greatly increases the memory required to edit
and render a movie. Shorter intervals between key frames enable faster seeking and reverse playback, but can significantly increase the size of
the file.
3G export settings
For more information on 3G settings, search for 3G on the Apple Computer web site.
File Format 3GPP and 3GPP2 are standards for the creation, delivery, and playback of multimedia over third-generation high-speed wireless
networks. 3GPP is for GSM networks and 3GPP2 is for CDMA 2000 networks. 3GPP (Mobile MP4), 3GPP2 (EZmovie), and AMC (EZmovie) are
for specific networks. 3GPP (Mobile MP4) is for NTT DoCoMo's i-motion 3G service. 3GPP2 (EZmovie) is for KDDI's 3G network service. AMC
(EZmovie) is for KDDI subscribers with AMC-capable phones.
Video Choose Video from the pop-up menu below the File Format menu and specify the following:
Video Format Selects the codec used during video export. If your source movie has only one video track and it 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,
Specify the sequence of frames to render.
Renders the frames selected by the work area bar in the Animation panel.
