# Kino FX

Kino provides some basic audio and video effects via the FX tab on the main window.

Being an experimental implementation, this version is far from fully featured. It does, however, have plug-in functionality so third party developers can extend the basic set provided.

## 1. Selection of the Frames

The Frames tab allows you to specify the source of your frames.

- Overwrite allows you to select a range of frames in your project for processing.

- Clicking on a scene thumbnail on the left will cause the range of frames selected to change
- Narrow down the selection either manually or using the Limit To option.
- The Advanced option provides a means of perform additional processing such as slow motion, 'stop frame' and reversal operations.

- Create allows you to insert new frames into your project from a variety of sources

- The built-in sources include various colour manipulators and imports of single frames
- Installed plug-ins will be appended to the list of those available
- The position is either before the current editor frame or at a user selectable position - selection of a scene on the left will change the latter

Note that neither option physically alters your original footage.

## 2. Selection of a Video Effect

Video effects fall into two categories:

- Filters affect only those Frames selected in the first step

- The built-in filters provide effects which range from do nothing, black & white conversion to various annoying ;-) mirroring and swapping effects
- Installed plug-ins will be appended to the list of those available

- Transitions take two sets of frames as input (referred to as a and b frames) and provide functionality to merge them together in some way:
  - The built-in transitions provide a small collection of fade and wipe functionality
  - Installed plug-ins will be appended to the list of those available
  - User selectable b-frames and direction can also be specified

  A few notes on transitions are in order here. By default, a transition affects those Frames selected by combining them with those immediately following - so if you want to cross fade the last 25 frames of the previous scene with the first of 25 of the following, you would need to select the Frames : Overwrite option, select your first scene from the left and specify the Limit to Closing 25 frames, and select the fade transition with frames following.

  The forward or reverse direction of the transition becomes apparent when selecting a fade in combination with a colour (fade to/from black, white, pink etc) or a wipe (where you can reverse the selected direction of 'left to right' to 'right to left').

  In the case of a transition, you will need to take care of audio. By default the audio of the a-frames are retained, and this may not be the effect you were looking for.

## 3. Selection of an Audio Effect

Audio effects fall into two categories:

- Filters affect only those Frames selected in the first step

- The built-in filters provide effects which range from doing nothing, silencing or fading the audio received
- Installed plug-ins will be appended to the list of those available

- Transitions take two sets of frames as input (referred to as a and b frames) and provide functionality to merge them together in some way:
  - The built-in transitions provide a small collection of switch, dub and mix functionality
  - Installed plug-ins will be appended to the list of those available

  The b-frames of the transitions are driven by the Video : Transition selection and though dub is misplaced in this release, it can be safely used in non-transition image effects.

## 4. Preview

Preview provides a quick way for you to preview your effects before Rendering them. By default audio is turned off, all frames are shown and playback is restricted to the affected frames only. You may alter these parameters, but it must be said that audio preview is only nominally supported - for all but the most basic effect, audio will stutter very badly.

## 5. Rendering

To render the full effect, specify a file stem in the file entry provided and click on the Render button. At the end of the processing, the rendered sequence will be put in place in a new scene in your video. Should you wish to undo the effect, you will have to return to the editor and use the undo functionality provided. You can also use join to avoid a proliferation of new scenes.

Please note: rendered sequences are never removed, even after you remove them from your video. The suggested approach to housekeeping is to use the same file stem throughout your project and periodically export the entire movie to a dv file format of your choice - you may then safely remove all the temporary files created.
