While I'd consider that 1/2 of the total pipeline, I think the OP is referring to being able to export portions of the timeline in batches. Consider, for example, setting up several AccuLips tracks with facial animations:
37% of original size (was 1352x256) - Click to enlargeFor me to export these, I need to manually drag-select the Collect Clip range, save the Motion Plus file. If I change something, I need to go through that process again. It's all very manual and tedious and slightly error-prone.
Consider how a program like Audacity lets you create permanent "labels" in a project, and then batch-export all content within labeled regions as separate files:
37% of original size (was 1352x256) - Click to enlargeI'd appreciate something like that. Perhaps the most versatile approach would be for Collect Clip to support permanent elements, each of which can be linked to an export object (like a MotionPlus file). A batch export would then trigger the re-export of each labeled item.
