What does emulate_motion do?

Question

After installing motion-trunk I noticed that images were no longer being saved as before. That is, previously if I set post_capure to 25 and the gap to something reasonable like 1-3 for example, I would have expected to have at least 25 seconds of output saved after motion was detected.

Apparently however in motion-trunk only pictures where there was motion are saved. If I set emulate_motion to on, will this make motion revert to the old behavior? Or will it do the really weird thing of saving images continuously non-stop all the time?

Thanks!

Answer

Answering myself: indeed, emulate_motion will save all images continuously non-stop. Will open another topic for my problem.
