Export formats for various devices and web sites
Finally, using the Adobe Media Encoder, you can export video in formats suitable for devices ranging from
professional tape decks to DVD players to video-sharing web sites to mobile phones to portable media players to
standard- and high-definition TV sets.
Workflow for exporting files
To export a video, still image, or audio file, you follow these basic steps:
1 Do one of the following:
• In a Timeline panel, select the sequence from which you want to export.
• In a Project panel or bin, select the clip from which you want to export.
2 Choose File > Export > Media.
3 (Optional) In the Export Settings dialog box, specify the portion of the sequence or clip you want to export. Drag
the handles on the work area bar. Then click the Set In Point button
and Set Out Point button .
4 To crop the image, specify cropping options in the Source panel.
5 Select the file format you want for your exported file.
6 (Optional) Select a preset best suited for your target means of playback, distribution, and audience.
7 To customize the preset options, click an available tab (Video, Audio, and so on) and specify the appropriate
options.
8 To include XMP data, choose Include Source XMP Metadata in the panel menu.
9 Click OK. Adobe Media Encoder opens with the encoding job added to its queue.
By default, Adobe Media Encoder saves the exported file in the folder where the source file is located, with the
extension for the format specified appended to the end of the filename. It is also possible to specify watched folders for
various types of exported files.

About compression of movie files
Compression is essential for reducing the size of movies so that they can be stored, transmitted, and played back
effectively. When exporting or rendering a movie file for playback on a specific type of device at a certain bandwidth,
you choose a compressor/decompressor (also known as an encoder/decoder, or codec), to compress the information
and generate a file readable by that type of device at that bandwidth.
A wide range of codecs is available; no single codec is best for all situations. For example, the best codec for
compressing cartoon animation is generally not efficient for compressing live-action video. When compressing a
movie file, you can fine-tune it for the best-quality playback on a computer, a mobile device, the web, or a DVD player.
Depending on which encoder you use, you may be able to reduce the size of compressed files by removing artifacts that
interfere with compression, such as random camera motion and excessive film grain.
The codec you use must be available to your entire audience. For instance, if you use a hardware codec on a capture
card, your audience must have the same hardware codec installed, or a software codec that emulates it.
