## Situation Review After Two Years of Silence

17 Apr 2019

This blog has been silent for two years, but progress on this restoration project has been on-going, albeit with some significant pauses due to other demands on my time. Read entire post

## Home-Grown Jitter Stabilisation — Part 7 — The Stabilisation Works!

21 Apr 2017

Having spent the previous six posts explaining the jitter stabilisation process for the 1963 kine of Marianne, let’s take a look at how well it works. Read entire post

## Home-Grown Jitter Stabilisation — Part 6 — A Stabilisation Workflow

03 Apr 2017

For those of you not completely bamboozled by this excursion into the very-technical, here is a summary of the whole stabilisation process developed for the Marianne kine scan. Read entire post

## Home-Grown Jitter Stabilisation — Part 5 — Odds and Ends

20 Mar 2017

In this post we look at a few odds and ends that arose during the stabilisation exercise: Dealing with frame defects and splice bumps, adding frame numbers, and re-combining frames into a video file. Read entire post

## Home-Grown Jitter Stabilisation — Part 4 — A Bit of Geometry and Maths

03 Mar 2017

The last post described using image correlation to measure the motion of the white dots in each of the four frame corners. These white dots move together with the video raster. Stabilising the white dots will stabilise the unwanted movement or jitter of the video raster. Read entire post

## Home-Grown Jitter Stabilisation — Part 3 — Image Correlation to Detect Movements

02 Feb 2017

In the last couple of posts dealing with “Home-Grown Jitter Stabilisation”, we established:

• The jitter comprises displacement, rotation and vertical scaling.
• There is a white dot (partially) visible in each of the four corners of each scanned film frame. These dots move together with the video raster.
• If we can measure the frame-to-frame movement of these dots, we can calculate and then correct (i.e. remove) the jitter.

## Home-Grown Jitter Stabilisation — Part 2 — Three Kinds of Motion

07 Dec 2016

Let’s put some visuals to this idea of stabilising the jitter in the kine scans.

As I mentioned in the last post, the jitter actually comprises three kinds of motion:

## Home-Grown Jitter Stabilisation — Part 1 — Could it be Done?

28 Nov 2016

As mentioned in the previous post, Promoscape had been unable to deal with the jitter: “With regard to stabilisation, we can’t find a cost effective and consistent way to achieve this with the footage.”

They explained that the jitter was not just horizontal and vertical movement (displacement) but included rotation as well.
