Render manager to remember in and out points
When you try to make multiple renders from the same comp using the work bar.
It currently will render the work bar even after you set the render settings for a comp, and then move the work bar to start a new render later in the same comp.
For example if you set a render with work bar in and out of 0:00-0:10 set a render task... Ctrl M.
Then make a new render from work bar... 0:20-0:30 Ctrl M, it will still render both files as 0:20-0:30.
Thanks for filing this issue. What you describe is the way After Effects is designed to work.
When you send a comp to the render queue, that render item remains “live” until you start the render queue. What this means is that any changes you make to the comp after adding it to the render queue will be reflected in the render item. This includes any changes to the comp including adding/removing/modifying layers, changing the comp dimensions or duration, or modifying the work area.
If you want to render multiple different durations of the same comp, there are a couple of ways to do this:
1. After you set the work area for the first duration and add the comp to the render queue, open the Render Settings dialog for that render item. Notice that the Time Span option is set to Work Area (this is the default unless you have chosen a different Render Settings template), and the Start, End, and Duration values reflect the current work area. Now click the Custom button next to the Start, End, and Duration values, and then simply click OK in the Custom Time Span dialog. The Time Span option will now be set to Custom, and those values are locked. Click OK in the Render Settings dialog. Change the work area in your comp and add the second instance to the render queue, and repeat the above steps to lock the custom time span values.
2. Export the comp using Adobe Media Encoder instead of using the render queue in After Effects. (Choose File > Export > Add to Adobe Media Encoder Queue.) The workflow with AME is different than the workflow with the render queue: AME will lock all aspects of the comp; any changes you make to the comp will NOT be reflected by any instances of the comp you have previously queued in AME. This is also by design: AME creates a temp copy of the project file so that you can continue to work in After Effects while AME renders and exports the comp.
