Capturing video frames in Timing Captures

Steven Pratschner
Program Manager

Starting with the 2505.09 release of PIX on Windows, an option has been added to Timing Captures to record video frames along with the timing data.  If the option to collect video frames is selected before a capture is taken, PIX will add a lane named Video Frames to the Timeline view. This lane will contain images that show the video frames over the duration of a capture. Viewing video frames alongside timing data allows you to see the state of the title at the point where a performance problem occurred.

Select the “Select a video capture source…” button to opt in to collecting video frames.

Doing so displays a dialog prompting you to select a video source.  You can choose to collect video for all the content on a given monitor, or for a specific window.  Clicking the desired source closes the dialog and enables video capture.

When a capture is opened, the Video Frames lane shows the image of each frame aligned with the lanes containing the timing data.

Selecting a frame populates the Element Details view with the detailed image. By default, the image will be viewed in “fill” mode, in which the image will be scaled to fit in the Element Details window. Switch the Video Frame Options to None using the Display Options panel to view the image at full size.

Right clicking on a video frame in the Element Details view brings up a context menu to copy the video frame to the clipboard or save it to a .bmp file.

Clicking the Show Full Size button in the Element Details view brings up a dialog that shows the video frame at its full size.

As always, keep the bug reports and feature requests coming using the PIX Feedback button in the upper right corner of the PIX UI.
