It might help the people who are capturing their behavior, and help the automated processing of the data collected, if;

There was a function, possibly provided by a plugin, that just by clicking on a button, would activate standardized methods for capturing data types.
The user may be presented with choices on what to capture.

Options might include, screen capture of each window redraw, video, mic (talk through), debug info capture, timing, etc.

Bundle all the data together and send off in a package kit.

It would work similar to macro record in a word processor, and could be edited.

This would make it far easier to be tested in real world situations, because you just need to "turn it on".
No need to click a screen capture each time - the screen is grabbed automatically by detecting pop-ups, and new pages.
The stuff that was recorded before any problem or scenario of interest, can be clipped out.
At the end of a session, or every "so often" the user could be prompted to delete everything recoded so far, for convenience.

No need to try to re-construct some event that has already happened.

Also very handy as a debug for anything.

Having recorded debug info, the data could be edited to swap elements in the situation such as the theme, version of software/plugin.
These could be collected as "typical use scenarios", that can then be automatically replayed through any newly developed system.

It helps capture re-useable tasks for automatic testing.

The user may choose which programs they want to use for video, audio, screen captures, etc on their device, but the dogfood system triggers the capture, and collects it all together for editing, and sending.

The dogfood editor basically lays all the data in the time line, so when the user selects a video clip, or section of a series of screen captures, for the dog food clip, the editor will clip the other information like debug, and mouse clicks, etc.

Have a button on the viewed page to click on as a bookmark. So the user can go back latter to clip the sequence, after they have finished their actual task.
