Producing H.264 with the Adobe Media Encoder
Adobe Media Encoder
Adobe significantly enhanced the Flash Video Encoder in Creative Suite 4. There is now both stand-alone operation and batch encoding capabilities. As before, you can access H.264 encoding by choosing different formats in the Format pop-up menu. When producing for Flash Player, you should always use the FLV|F4V option, which lets you produce both VP6- and H.264-encoded files for Flash Player distribution.
Typically, you'll choose your codec by choosing a preset that uses one format or the other. Alternatively, you can change your codec in the Format tab by choosing FLV for VP6 or F4V for H.264 (see Figure 10).
The easiest way to work with Adobe Media Encoder is to choose a preset that's either the same size or slightly larger than your target resolution. This will ensure that the appropriate profile and level are selected.
All presets accessible through Adobe Premiere Pro default to the Main Profile, rather than High. While any quality difference is likely to be very minor, I generally change this to the High profile before encoding (see Figure 11). Other than this, the only setting that I modify is the Set Key Frame Distance in the Advanced Setting section, which I always enable, and insert 300 for Key Frame Distance. I always use the default values for Audio, changing only the data rate and channels to match my content and encoding targets.
