These presentations demonstrate how a project's average deviation can be improved significantly by optimizing only a few lens parameters.

Part 1 demonstrates how to use 3DE4's Parameter Adjustment Window for optimizing focal length and lens distortion parameters. Its features and general workflow are being discussed in detail.

Part 2 shows techniques how 3DE4's matrix tool can be used to extract distortion and focal length information out of single, regular sequence frames, without tracking any points at all.
