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,
don't choose a data rate higher than the available bandwidth.
Optimized For
Specifies the intended delivery method if you choose H.264 from
the Video Format menu. This setting tells the Codec how much the
data rate can vary above and below the data rate you choose.
Image Size
Specifies a standard for sending the file to a mobile phone.
Current maintains the source material size; the resulting file may
not play on a mobile phone. Choose Custom to specify a size not
listed in the menu.
Preserve Aspect Ratio Using
Specifies an option when you’re changing the image size and
the movie needs to be scaled to the new dimensions. Letterbox scales
the source proportionally to fit 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. Fit Within Size adjusts
to the destination size by fitting to the longest side, scaling
if necessary.
Frame Rate
Specifies the frames per second (fps) during playback. In
most cases, your video will look better if you choose a number that
is exactly divisible by the fps of your source. For example, if
your source is captured at 30 fps, choose a frame rate of 10 or
15. Don't choose a rate larger than that of your source material.
Key Frame
Specifies how frequently keyframes are created in the exported video.
A higher keyframe rate (lower number) improves video quality, but increases
the file size.
Video Options
If available, click the Video Options button to open the
3G Advanced Video Settings dialog box. Depending on the video, you
can specify whether to add re‑sync markers inside the video frames
to help with packet loss recovery when streaming. With H.264 video,
you can also speed up the compression process (for preview purposes,
for example) by choosing Faster Encode (Single‑pass). The default
option, Best Quality (Multi‑pass), allows the Codec to determine
how many passes are needed to compress the data for the best quality.
Audio
Although the Audio option is available in the pop‑up menu
below the File Format menu, Photoshop Extended CS3 does not support
audio tracks.
Text
Choose Text from the pop‑up menu below the File Format menu
and specify the following:
Text Format
Specify formatting or no formatting for displaying the text
on mobile devices.
Text Encoding
Selects UTF8, UTF16, or (if available) STML Native encoding.
Require Text Capability On Handset
Allows the movie to play only if the text can be displayed
on the receiving device. Deselect this option to allow the audio
and video to play even if the text can't be displayed on the device.
Note: These
options are available only if your movie has a text track, such
as credits, titles, subtitles, and so forth.
Streaming
Choose Streaming from the pop‑up menu below the File Format menu
and specify the following:
Enable Streaming
Creates a file for RTSP streaming to QuickTime Player. This option
creates a hint track (instructions necessary for streaming a file).
Optimize For Server
Helps the server to process the file faster, but increases
the file size.
Advanced
Choose Advanced from the pop‑up menu below the File Format menu
and specify the following:
Restrict Distribution
Specifies how many times the file can play back on the handset
once downloaded. Also specifies file expiration options: set the
file to expire in a number of days or enter a date. If your file
is in Mobile MP4 or EZmovie format, you can restrict distribution
so that once the file is on a handset it can't be sent or copied
elsewhere.
Fragment Movie
Enables the file to download via HTTP in small pieces so
that playback can start faster and so that larger files can be played
on the handset (only the fragment, not the entire movie, must fit
on the handset at one time).
In the Render Video dialog box,
select QuickTime Export and then choose AVI from the pop‑up menu.
Click the Settings button.
In the AVI Settings dialog box, make sure Video is selected.
Important: Although the AVI Settings dialog
box has Sound options, Photoshop Extended CS3 does not support audio
tracks.
Under Video, click the Settings button and set the following:
Compression Type
Chooses the video compressor (Codec) to compress your video.
For the highest quality at the lowest data rate (or the smallest
file), H.264 is recommended.
Frame Per Second
Specifies the number of individual images shown every second.
NTSC is generally the standard video format and is 29.97 fps. PAL
is a European video format that is 25 fps. The standard for film
is 24 fps. QuickTime movies are sometimes created with a slower
frame rate to reduce bandwidth and CPU requirements.
Movies
with higher frame rates display motion better, but have larger file
sizes. If you choose a frame rate that's lower than the movie's
current frame rate, frames are deleted. If you choose a number that's
higher than the movie's current frame rate, existing frames are
duplicated (not recommended, since it increases file size without
improving quality). In most cases, your video will look better if
you choose a number that is exactly divisible by the fps of your
source. For example, if your source is captured at 30 fps, choose
a frame rate of 10 or 15. Don't choose a rate larger than that of
your source material.
Key Frame Every
Specifies the keyframe frequency. A higher keyframe rate (lower
number) improves video quality, but increases the file size. With
some compressors, an additional keyframe is inserted automatically
if too much of the image has changed from one frame to the next.
In general, one keyframe 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 keyframe frequency to one keyframe 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.
The following settings 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
Specifies an option if the movie is scaled to new pixel dimensions.
Letterbox scales the source proportionally to fit 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.
Important: Although
the DV Export Settings dialog box has Audio Format options, Photoshop
Extended CS3 does not support audio tracks.
In the Render Video dialog box,
select QuickTime Export and then click the Settings button.
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.
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.
Image Size
Specifies the pixel dimensions of your exported video.
Current maintains the source material size. To specify a size not
listed in the Image Size menu, choose Custom.
Preserve Aspect Ratio Using
Specifies an option if the movie needs to be scaled to
the new pixel dimensions. Letterbox scales the source proportionally
to fit 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. Fit Within Size adjusts to the destination size
by fitting to the longest side, scaling if necessary.
Frame Rate
Specifies the frame rate for the playback of your exported
video. Usually, your video looks better if you choose a number that
is exactly divisible by the frames per second (fps) of your source.
For example, if your source is captured at 30 fps, choose a frame
rate of 10 or 15. Don’t choose a rate greater than that of your
source material.
Key Frame
Specifies that keyframes are generated automatically
or specifies how frequently keyframes are created in the exported
video. A higher keyframe rate (lower number) improves video quality,
but increases the file size.
(MP4 file format only) Click the Video Options button
and specify the following:
Re‑sync Markers
(MPEG‑4 Basic and MPEG‑4 Improved only) Uses re‑sync markers
in the video bit‑stream. This can help regain synchronization due
to transmission errors.
Restrict Profile(s) To
(H.264 only) Selects profiles for playing video files
on a device that conforms to one or more of the standard's profiles.
Encoding Mode
(H.264 only) Specifies whether you want the best quality
or faster encoding.
