Chapter 10, Using the Matrox MAX H.264 Codec
¦NoteUse H.264 level 3.1 to create HD video for use with Apple iPad.
10 Select the Noise filter level that will be applied to your video before
encoding. Increasing the noise filter level reduces the amount of high
frequencies in your source video by softening the high-detail portions of
your video. Since high frequencies require more bits to encode, increasing
the noise filter level leaves more bits available for the encoding of other
frames, which can improve the overall quality of your encoded video.
However, if you lose too much detail in your encoded video you may need to
decrease the noise filter level.
11 Click OK.
12 If you want to scale your source video for export, specify the new frame size
in the
Resize option under Video Filters in the Inspector Panel.
¦NoteThe minimum frame size is 64×64, and the maximum frame size
depends on the H.264 level selected in step 9. The horizontal and vertical
values must be even numbers.
13 Set your desired audio settings. To export a clip for use with Apple iPad,
iPod or iPhone devices, you must select
AAC or AAC QuickTime as the
Audio Codec in the Inspector Panel.
14 Drag a deployment location to the Workflow Panel, and encode the file as
you would normally.
