Best practices for content on mobile devices
Adobe Device Central is an application that helps you optimize your video files for playback on a variety of mobile
devices. You can use Device Central to test content created in the following Adobe products: Adobe Photoshop, Adobe
Illustrator, Adobe Dreamweaver, Premiere Pro, and Adobe After Effects. Use the tips below to create video content
that is optimized for display on mobile devices.
Tips for creating video for mobile devices
Use these tips when shooting content for mobile devices:
• Tight shots are better. Try to keep the subject separated from the background; the colors and values between
background and subject should not be too similar.
• Be aware of lighting. Poor lighting is a greater problem with mobile devices and can reduce visibility on small
screens. Shoot and adjust with this limitation in mind.
• Avoid excessive panning or rolling.
Use the following tips when editing video with Adobe Premiere Pro and After Effects:
• Set the frame rate for the output movie according to output device or output type. For example, a commercial in
After Effects might be rendered at 15 frames per second (fps) for distribution on mobile devices, but at 29.97 fps
for broadcast television in the USA. In general, use a lower frame rate. A frame rate of 22 fps is a good compromise
for reducing file size without losing quality
• Make the movie as small as possible and remove any extraneous content, especially empty frames. Many actions
can be done pre-encoding to limit file size. Some of them apply to shooting techniques, while others (for instance,
using motion-stabilization tools in After Effects or applying a noise-reduction or blur effect) are post-production
tasks that facilitate the compression portion of the encoder.
