Whip pan transition

Recommended Posts

A whip pan is a type of pan shot in which the camera pans so quickly that the picture blurs into indistinct streaks. It is commonly used as a transition between shots, and can indicate the passage of time or a frenetic pace of action.
Wikipedia source : https://en.wikipedia.org/wiki/Whip_pan

This effect can be simulated in post processing by applying a directional blur filter to the images. PTE has a blur effect (Gaussian blur type) that acts in all directions at the same time, but does not provide a directional blur filter. However, this result can be approached by superimposing a significant number of the same image, each layer being shifted in the direction of the desired blur. In addition, each image will have to be configured with a low opacity level to be almost transparent.
These transitions are to be used with a short duration (0.3 to 0.6 seconds). I think that an interesting result is obtained with a transition time of 0.4 seconds.
These transitions are very CPU intensive, so I only use them with mp4 video output.

Below is a demonstration of the transition effects :

Great work! Thanks!

We added a Motion Blur option in video output in future PTE 10. With this option, all animated objects will be blurred in a direction of their motion automatically. Static objects are not affected.

This post-processing requires more powerful video card we currently we enabled it only for video output. Your implementation suitable also for EXE shows in real time.

Thank you Igor,

I couldn't have hoped for better! Having the motion blur option in PTE 10 is very good news.
This new option will undoubtedly be an important source of creativity.

Igor, just one question: will the motion blur option also work for a zoom in/zoom out effect as in the example below?

Yes, it should work. Motion blur applies automatically for all kind of animated objects (in any directions) excluding video clips (because PTE cannot generate intermediate frames for video clips objects).

Please write me your impressions when you try it later.

Pascal,

Probably you noticed some color artefacts on a picture during your effect? It occurs due to lack of accuracy with many multiplications at 8-bit per color calculations. 

In PTE 10 we used 16-bit per color channel (64-bit per pixel) calculations to keep absolutely exact colors for Motion blur effect.
