DVO Twister

DVO Twister is an advanced software standards conversion tool.

 

ch-dvo-twister-menu

 

To use DVO Twister, you should set up a project and composition configured for your target format.

Parameters

Enable

This toggle button allows you to enable/disable the DVO Twister effect. By default, as soon as the effect is added it is applied/enabled.

Mode

ch-dvo-twister-mode

 

The mode option lets you choose the source and target format for the conversion. Available modes include :

 

50i to 23.98p

50i to 24.00p

50i to 29.97p

 

50i to 59.94i

50i to 60.00p

 

59.94i to 23.98p

59.94i to 24.00p

59.94i to 25.00p

59.94i to 50i

59.94i to 50p

50p to 60p

60p to 50p

 

23.98p to 29.97p

23.98p to 50.00i

 

29.97p to 23.98p

29.97p to 50.00i

16.00p to 24.00p

16.00p to 25.00p

 

18.00p to 24.00p

18.00p to 25.00p

 

20.00p to 24.00p

20.00p to 25.00p

 

Processing Mode

ch-dvo-twister-proc-mode

Values :

Narrow, Medium, Wide, Auto

Default :

Narrow

 

The Processing Mode affects how motion is detected and selects between three main modes. The Auto mode automatically selects the most appropriate setting based on the source and target mode chosen.

 

dv_alert

Only has an effect when Motion Mode is set to Motion Comp.

Motion Mode

ch-dvo-twister-motion-mode

 

Values :

Motion Comp, Interpolated, Nearest Frame

Default :

Motion Comp

 

This determines how the images are recreated in the target format.

Motion Comp

This uses motion compensation and is the default. This allows the accurate recreation of fields and frames using the Digital Vision Phame motion vector algorithms.

Interpolated

This is a simple method that recreates correct target fields and frames by careful mixing of the input source. This method will often produce a lower quality result than the motion compensated approach (blurs, jerky motion). Try if Motion Comp fails.

Nearest Frame

This uses no processing other than skipping or repeating frames to output the same clip duration.

Cut Mode

ch-dvo-twister-cut-mode

 

Values :

Across Scene, Inside Scene, Inside Scene Frame Aligned

Default :

Inside Scene

 

DVO Twister has an internal scene detector and the Cut Mode determines how images adjacent to a scene cut are aligned.

Across Scene

This ignores the cut and blends the images. This will not provide in a clean cut but is sometimes preferred as it is the most accurate representation in terms of alignment in time.

Inside Scene

This aligns the cut to the nearest video field.

Inside Scene Frame Aligned

This aligns the cut to the nearest output video/film frame and so results in the cleanest cut.
