How does the Hyperlapse feature work?

We call it “Hyperlapse by SteadXP” (patent pending), even if it is more of an advanced speed ramping feature to be precise 😉
If you want to become an Hyperlapse beta-tester, please contact us at !

With this new Hyperlapse feature, it is now possible to speed ramp and stabilize your footage at the same time, with unprecedented fluidity:

  • Our software will first analyze motion in your video and initialize a speed ramping spline. Typically, the algorithm will apply a maximum acceleration factor on “straight lines” and decelerate on turns.
  • Of course you still get a complete control over the speed ramping spline (black spline controlled by user editable keyframes). The white spline shows the instantaneous angular velocity (on output video) at any time.
  • You can preview the result in real time (with the help of our new preview buffer with audio support). You can load an external audio track, to synchronize a music track for example.
  • But the real trick is that SteadXP will stabilize whatever the speed ramping evolution : no more abrupt rotation speed variation on a speed ramping change!
  • And a lot more will come in the future around this feature!


 Speed Ramping / Hyperlapse (patent pending)

The stabilized trajectory can now be optimized in both space and time:

  • the Flow Speed slider controls the target rotational speed
  • the Keyframe density slider controls the smoothness

To show the hyperlapse spline and keyframes, click on 159 in the timeline until 159 is displayed.


The hyperlapse spline is represented in black. Hyperlapse keyframes are represented by dots on the hyperlapse spline.
The hyperlapse spline will be represented in red where the hyperlapse value is equal to x1.

The rotational speed is represented by the white spline.
You can control the rotational speed by adjusting the speed ramping factor (hyperlapse speed).

We recommend shooting at high framerates for better results. Like 50 fps for a 25 fps planned export (i.e speed ramping factor of x2, or more).
Essentially because transitions from x3 ➞ x2 are less visible than from x2 ➞ x1: parallax speed evolution of moving foregrounds (regarding the camera) are affected by speed ramping factor changes and remain visible on frame.
x1 ➞ x2 multiplies every parallax speeds by 2, while x2 ➞ x3 “only” multiplies them by 1.5, hence less visible.

Interact with hyperlapse keyframes when the timeline is in Trajectory mode to adjust the speed ramping factor:

  • Create an hyperlapse keyframe by double-clicking on the timeline
  • Modify an hyperlapse keyframe by scrolling the mouse wheel on it
  • Delete an hyperlapse keyframe by double-clicking on it (multiple selection by mouse drag)
  • Copy an hyperlapse keyframe by right-clicking on it ➞ Copy hyperlapse keyframe
  • Paste an hyperlapse keyframe by right-clicking on the timeline ➞ Paste hyperlapse keyframe
  • Reset hyperlapse keyframes by right-clicking on the timeline ➞ Reset hyperlapse keyframes

Use the Real Time Preview for a smooth playback experience of your hyperlapse sequence with no long wait.

The hyperlapse value of the frame is displayed in the top left corner of the frame:
