Re: Video effects

[Diego Martinez <diegomarti@xxxxxxxxx>]

Hello Ken,
what Kevin is pointing out is that you can trim your speakers images from a still background. This is commonly done by creating a neutral green or blue background that easily allows to trim figure from it. Zooming you will see how grosely the soft trims, sometimes you do not need to zoom to see it. Rapid movements in the figure are more dificult to isolate.

With this technique you will still need to produce your urban backgrounds. This will be best done with the same camera and lens you use for the figures.

Light and angle will enhance the illusion if keeped matched during figure and background takes.

This is the home made way to go, or you jast can paste some stocked background videos. Try at least to match camera and archive material resolution.

Regards

Diego
