Tips for creating video for mobile devices
You can export a sequence for use on Apple iPods, 3GPP cell phones, Sony PSPs, or other mobile devices. In Export Settings, select an H.264
format preset made for the target device.
FAQ: "How do I export a movie for YouTube, Vimeo, iPad, iPhone, Apple TV?”
You can use Device Central to preview how a movie will appear on a wide variety of mobile devices.
For information about exporting to the FLV and F4V formats, see the video tutorial Creating FLV and F4V files .
Moving assets between Adobe Premiere Pro and Adobe Flash
In Adobe Premiere Pro, you can add Flash cue point markers to a timeline. Flash cue point markers serve as cue points in a rich media
application. There are two types of cue point markers: event and navigational cue point markers. You can use navigational cue point markers to
navigate to different sections of FLV and F4V files, and to trigger the display of onscreen texts. You can use event cue point markers for triggering
action scripts at specified times in FLV and F4V files.
You can export a movie from Adobe Premiere Pro directly into the FLV and F4V formats. You can choose from severalExport Settings presets.
These presets balance file size against audio and video quality to achieve the bit rate needed for any target audience or device. If you export the
movie with an alpha channel, you can use the movie easily used as a layer in a rich media project.
You can import the FLV or F4V file into Adobe Flash. Flash reads sequence markers as navigational or event cue points. In Flash, you can also
customize the interface that surrounds your video.
Alternatively, you can use Flash to create animations for use in movies. You can create an animation in Flash. You can export the animation as an
FLV or F4V file. Then, you can import the FLV or F4V file into Adobe Premiere Pro for editing. In Adobe Premiere Pro, for example, you could add
titles or mix the animation with other video sources.
Tips for creating FLV and F4V files
Follow these guidelines to deliver the best possible FLV or F4V files:
Work with video in the native format of your project until your final output
If you convert a precompressed digital video format into another compressed format such as the FLV or F4V format, the previous encoder can
introduce video noise. The first compressor already applied its encoding algorithm to the video, reducing its quality, frame size, and frame rate.
That compression could have introduced digital artifacts: noise. This noise affects the final encoding process, and a higher data rate is often
required to encode a good-quality file.
Strive for simplicity
Avoid elaborate transitions—they don’t compress well and can make your final compressed video look “chunky” during the change. Hard cuts
compress better than dissolves.
Know your audience data rate
When you deliver video over the Internet, produce files at lower data rates. Users with fast Internet connections can view the files with little or no
delay for loading, but dial-up users must wait for files to download. Make the clips short to keep the download times within acceptable limits for
dial-up users.
Select the proper frame rate
Frame rate indicates frames per second (fps). If you have a higher data rate clip, a lower frame rate can improve playback through limited
bandwidth. For example, if you compress a clip with little motion, cutting the frame rate in half can save you only 20% of the data rate. However, if
you compress high-motion video, reducing the frame rate has a much greater effect on the data rate.
Because video looks much better at native frame rates, leave the frame rate high if your delivery channels and playback platforms allow. For web
delivery, get this detail from your hosting service. For mobile devices, use the device-specific encoding presets and the device emulator available
through Adobe Media Encoder in Adobe Premiere Pro. If reducing the frame rate, the best results come from dividing the frame rate by whole
numbers.
Note: To embed video clips into a SWF file, match the frame rate of the video clip to the frame rate of the SWF file. To encode video using the
