Pro Tools and Pro Tools HD 10.0 on Mac OS X 10.6.x (“Snow Leopard”) and Mac OS X 10.7.x (“Lion”) — 10/13/11 4

Known Issues

The following section documents known issues you may encounter when using Pro Tools 10.0 and Pro Tools HD 10.0, along with

workarounds if they exist.

General Pro Tools Issues

Pro Tools intermittently Blocks Playback on Mac OS X 10.7.x (“Lion”) (PTSW-142640)

On certain system configurations, Pro Tools may intermittently not play back when you press the Spacebar. When this occurs,

“Pause” is indicated in the lower left corner of the Edit window and the transport may not respond. This state may persist for sev-

eral minutes before normal operation resumes.

When this occurs, try changing a setting in the Playback Engine and then changing it back to the original setting to allow play-

back.

Playback of QuickTime video in Pro Tools may stutter or drop frames

When monitoring QuickTime playback in the Pro Tools Video Window on the computer screen, the video image may stutter or

drop frames. To improve results with QuickTime playback, try any of the following:

• Disable Continuous Scrolling.

• Close unnecessary UI windows.

•Try using the DNxHD codec.

• If you have an available PCIe slot in your computer, try using one of the following:

• A supported Blackmagic video card

• A supported Canopus video peripheral for QuickTime DV playback

• Consider using an Avid option that includes a video solution:

• The Video Satellite option offers guaranteed performance for Avid video playback (QuickTime can also be used via AMA).

• The Video Satellite LE option offers a way to integrate a Blackmagic video card into a system

• The Avid Mojo SDI peripheral offers guaranteed performance for standard-definition Avid video

Synchronizing to External Clock with a Different Sample Rate from the Session Results in the Following Error: “The current

playback engine does not support a sample rate of 44.1 kHz” (PTSW-127065)

In certain circumstances, attempting to synchronize to an external clock that has a different sample rate than the session may re-

sult in the following error: “The current playback engine does not support a sample rate of 44.1 kHz.” On Mac OS X, this may be

preceded by the error “Pro Tools has re-set the sample rate of the HW device because it was changed by another application.” If

this happens, correct the sample rate mismatch and re-select the correct clock rate.

Templates Retain I/O Settings and Some Preferences, Display Settings, and Window Layouts (PTSW-47133)

Pro Tools Session Templates Retain the I/O settings and some of the preferences, display settings, and window layouts from the

system on which the template was created. Consequently, created a new session based on a template restores several session prop-

erties from the original system. These properties are retained by Pro Tools until you change them or another session or template

is opened that replaces them. This also means that if a new blank session is created after using a template, the properties from

the template will be used for the new session.

The properties retained from templates include default track height, view settings, window size and position, and I/O Setup. You

can update templates by making the desired changes, using the File > Save as Template command (be sure to select the “Install

template in system” option), and then selecting the template you want to replace.

For known issues specific to any of the software options for Pro Tools HD, see the Satellite Link Read Me, the Video Satellite

Read Me, or the Video Satellite LE Read Me.
