Premiere Pro:Working with the Adobe Media Encoder: Part Two

The Video Tab contains multiple parameters, some of which you can adjust, and others that you should leave at the default settings.

5. Click the Filters tab to open the Noise Reduction option (not shown). Avoid applying this filter unless your video is extremely noisy.

6. Click the Video tab to open the Video settings. Also be sure to review the Basic Video Settings to ensure that they are correct.

Tip: OutPutting MPEG-2 Files — When and Where:

When rendering video in Premiere Pro for Encore, you have two choices: outputting a DVAVI file or outputting an MPEG-2 file. If you’re working in DV and have made minimal edits, output in DV-AVI format and import that into Encore. If you’ve introduced significant or pervasive edits like color correction or brightness adjustments, or you’re working with HDV video, consider outputting from Premiere Pro in MPEG-2 format (with PCM audio). Here’s why. In the first example, minimal edits, Premiere Pro will simply output the original DV-AVI files, making only required changes, so you’re not adding a generation of processing. In the second example, with pervasive edits, if you output DV-AVI, Premiere Pro will have to apply the effects, then re-encode back into DV-AVI format. If you then encode that file into MPEG-2, you’ve added a compression generation. Ditto when producing SD DVDs from HDV video, since Premiere Pro will convert that to DV-AVI. If you encode directly to MPEG-2 in both cases, you avoid that generation. Will the difference be noticeable? Perhaps not, but the best practice is to introduce as few encoding generations as possible into the process

Note: Premiere Pro’s streaming presets can be very conservative. For example RealMedia resolution maxes out at 320×240 resolution, even when data rates exceed 1Mbps. To produce higher-resolution streaming videos, change the Frame Width and Frame Height parameters here. Don’t change MPEG resolutions (especially DVD), however, since you might produce a file that won’t import into Encore.

Be sure to review the Bitrate Settings. It’s relatively safe to customize many of these parameters, for example, changing constant bitrate encoding (CBR) to variable bitrate encoding (VBR), which will authorize Adobe Media Encoder to conserve bits on more easily compressed (e.g., lowmotion) segments of your video and apply more bits to more dynamic sections while achieving the same average bitrate overall. When producing MPEG2 files for DVD, however, your Target Bitrate shouldn’t exceed 7Mbps, and your Maximum Bitrate shouldn’t exceed 7.5Mbps, or the encoded file might contain data spikes that will interrupt playback on some DVD players.
