Join Lisa Larson-Kelley for an in-depth discussion in this video Converting a video using Adobe Media Encoder, part of Publishing Video with the Flash Platform.
Adobe Media Encoder is a powerful tool that lets you quickly and easily prepare your videos for Flash playback. In this lesson, we'll encode a raw video file using this free software. Now, here we see the main interface. I'm being prompted to add a raw video to the encoding queue. I can add one by dragging here from my hard drive, or I can click the Add button and select one that way. Let's go ahead and do that. I'll select the raw source video included with the exercise files, ojai_ad.mov.
Now, the first thing I want to show you is how to turn off automatic encoding. Adobe Media Encoder is set up to start encoding any video in the queue after two minutes by default. This can get very annoying, so I always turn off this feature. To do so, we'll go up to Adobe Media Encoder CS5, choose Preferences, and here we can see the box checked next to Start queue automatically. We'll uncheck that box and click OK. Now, we are ready to start encoding.
First, we'll want to specify what file format we want to encode. Adobe Media Encoder is truly a full-featured encoder. As you see here, it gives you many options, from QuickTime to FLV--even Blu-ray. Since we're encoding a video for playback in Flash, we want to choose FLV | F4V. Next, we need to choose encoding settings. Now, this can get a bit complicated. Choosing just the right settings for a specific video can really be an art, or at least a craft, that takes years to master.
So to take some pressure off, Adobe has kindly provided some helpful presets here. The default preset is F4V-Match Source Attributes (High Quality). For this exercise let's choose FLV-Match Source Attributes (Medium Quality) and this creates a video that uses the VP6 codec for video and the MP3 codec for audio. This will encode an FLV file that has the same dimensions as our source video and is optimized for smooth playback over an average Internet connection speed.
Now we could edit these encoding settings and create a custom preset, but we'll save that for a lesson later in this chapter. Finally, this last column indicates where our video file is going to be saved. By default, it saves the final file in the same directory as the original. Now, often you want to change the file name to reflect the encoding settings you used. Let's change ours by clicking on the Output File name and we'll change it to ojai_ad_MQ and then press Save. I'll go ahead and click Start Queue, and the video will begin to encode.
Adobe Media Encoder is now showing me details about the final encoded video as well as playing it back here as it works. When the file is finished, I'll have a nice green check mark next to the file and a freshly encoded video on my hard drive ready to play back in my Flash-based video player of choice. In this lesson, you got some hands-on experience on coding a raw source video using presets in Adobe Media Encoder. You can now confidently convert your videos into formats that will play in Flash and have a good foundation for diving deeper into the encoding settings.
