Matrox Axio realtime guidelines

In your Adobe Premiere Pro projects, you can use various combinations of

realtime Matrox CPU-based effects (Flex CPU effects), hardware-accelerated

effects (Flex GPU effects), and Adobe Premiere Pro fixed effects, all with

transparency.

Realtime means that the clips don’t require rendering and will play back in real

time without dropping frames (that is, there is no red indicator bar above the

segment).

The Matrox CPU-based effects are wipes, color corrections, chroma keys, luma

keys, move & scale, the chroma clamper, and Adobe Premiere Pro’s crop and

speed change. The Matrox hardware-accelerated effects are all the other Matrox

effects (such as page curls, 3D DVEs, surface finish effects, Premiere Pro fixed

effects and fades, etc.).

¦NoteOn Axio LE, the hardware-accelerated effects will be available only if

you have a display card that supports the Matrox hardware-accelerated effects in

Adobe Premiere Pro. For more information, see “Enabling and disabling the

Matrox hardware-accelerated effects in Adobe Premiere Pro” on page 249.

Matrox Axio constantly analyzes your sequence as you work, and will identify

which segments require rendering (with a red indicator bar above the segment).

For example, once playback of the sequence has stopped, a red bar will appear

over segments of the sequence that have dropped frames. Even when your system

is idle, Matrox Axio will analyze segments to determine if they require rendering.

Certain complex effects or combinations of effects can cause dropped frames

when previewing. Matrox Axio will always provide a preview of your output at

the best frame rate possible by analyzing the segments and dropping frames

systematically.

If you find that you have dropped frames when you export your project to tape

and those segments were not identified with a red bar, you can lower the

Realtime Indicator Threshold. For more information, see “Defining your

General settings” on page 74.

The maximum number of layers that can be played back in real time depends on

the capabilities of your system, your project’s video format, the compression

format of your clips, and the number and complexity of the effects you’ve applied

to your clips.
