The Timewarper is very similar to the Bulb Ramping mode. Different than Bulb Ramping mode, this mode changes the interval between each frame rather than changing the exposure. So that you can speed up or down some parts of your time-lapse video. This mode has 3 parameters and a warper setting.
Interval: This parameter defines the duration between each frame. The Interval can have a value from 13 milliseconds up to 100 hours.
Exposure: This value defines the exposure value for each photo. You can set a custom exposure up to 100 hours in milliseconds.
Frame: This parameter defines how many pictures are to be taken. You can set the frame number up to 99999. If you set the frame number to 0, this will mean that the time-lapse will continue until you stop it.
Warper Setting: This area allows you to change the speed of the timelapse by changing the interval for the specified area. The whole timelapse process is divided into 10 equivalent range by default. You can change the speed of each area by changing the interval. The longer the interval you set, the faster the video in this range.
