La Russie en 1917/19 version colorisée

The first step is to motion-stabilize a video. This is an important step because watching film as if it was originally shot on a tripod makes viewing far more pleasurable than wobbly footage. The human brain gets tired very quickly when watching motion-unstable video material.

The second step is to enhance the contrast, brightness and sharpness, as well as apply noise reduction and dust and speckle removal filters. How to do this the correct way involves a lot of experience and the treatment of every film will be entirely different.

The third step involves upscaling and/or enhancing to 1080p HD using contemporary A.I. software. This process adds a lot of clarity to almost any footage. In itself this stage is not too difficult providing you know how to set the correct parameters.

The fourth step is optional and involves artificial colorization of B&W footage. A very good software tool for this purpose is DeOldify that has to be applied online via a not very user-friendly Github interface.

The fifth and final step is to add sound and commentry and join the various film fragments by means of a sophisticated editor.
This editor is also used to correct the speed if necessary. Many old films were shot on hand cranked cameras with 15 to 18 fps. This causes the slapstick effect when playing such footage at 25 or 30 fps, so a special treatment is needed to generate the missing frames by means of frame interpolation.
