The latest versions of MegaPEG feature built-in flash video decoding. This means that motion graphics designers who are familiar with Flash can use it to author titles and effects which can then be encoded to 1280x720p or 1920x1080 for use in broadcast.

It's quite straightforward.

1. Open the Flash movie in QuickTime player and use Command+J to open the movie properties. Set the width/height of the movie to be the dimensions you plan to encode. For instance, for 720p, choose 1280x720.

2. Now save the Movie allowing for dependencies. This is also known as a "Reference Movie". Give the file a .mov file extension. Going forward in Mac OS X, FileType/Creator codes are deprecated, and so it is wise to always give a file the correct file extension.

3. Now, open MegaPEG Pro HD or MegaPEG HDTV and create a new batch. Drag the newly created reference movie onto the batch. Double click on the movie in the batch to open the Settings dialog box.

4. From the list of HD Movie templates, choose MPEG-1 HD 1280x720p (or whatever template you want to start with.

5. Click on over to the Process tab and make sure de-interlacing is off.

6. If you want an audio track, you need to have the Flash audio track separated out as an MP3 audio or AIFF track. MegaPEG can mux VBR MPEG-1 Layer 3 audio tracks as long as they do not contain ID3 tags.

7. Choose a setting for "Speed vs. Quality". I like to use Best myself.

8. Choose Make MPEG.

You will notice that MegaPEG does an exemplary job of handling CG/motion graphics, and this is especially evident when transcoding Flash movies. The resulting bitrate will often be outrageously low for High-Def.
