Creating Colour Sources

The Colour Source tool generates a virtual source that contains one or more identical frames of a solid colour or SMPTE or PAL colour bars at 75% or 100% luminance. When you use the Colour Source tool to create a custom colour source, you can save that colour in the colour palettes. You can also use this tool to create frames composed of video noise. Noise clips are not virtual sources — each frame in the clip is unique.

To create a colour source or noise clip:

1. With Video selected from the A/V Tools box, click Colour Source.

   The Colour Source controls appear.

   
   

   (a) Source Type box  (b) Luminance box  (c) Frequency box  (d) Resolution button  (e) Frame Code Mode box  (f) Timecode field  

2. From the Source Type box, select the type of frame you want to generate.

   Select:	To generate frames of:
   Colour	A solid colour.
   Noise	Monochrome video noise.
   Colour Noise	Colour video noise.
   SMPTE Bars	SMPTE standard colour bars.
   PAL Bars	PAL standard colour bars.

3. From the Luminance box, select 75% or 100% luminance.
4. From the Frame Code Mode box, select the framerate and drop frame mode for your colour source clip.

   Select:	To generate frames of:
   60 fps	60 frames per second (used for NTSC video).
   59.94 fps NDF	59.94 frames per second Non Drop-Frame (standard rate for NTSC). If you use 59.94 fps NDF, its indicated timings will not accurately correspond with real time.
   59.94 fps DF	59.94 frames per second Drop-Frame (standard rate for NTSC). This times the video accurately with real time by dropping the extra frames in the count.
   50 fps	50 frames per second (standard for PAL).
   30 fps	30 frames per second (mimics a film camera's frame-by-frame image capture).
   29.97 fps NDF	29.97 frames per second Non Drop-Frame (frame rate for colour NTSC). If you use 29.97 fps NDF, its indicated timings will not accurately correspond with real time.
   29.97 fps DF	29.97 frames per second Drop-Frame (frame rate for colour NTSC). This times the video accurately with real time by dropping the extra frames in the count.
   25 fps	25 frames per second (good for LCD monitors or display formats that are not interlaced).
   24 fps	24 frames per second (used to transfer a video signal to film).
   23.976 fps	23.976 frames per second. This frame rate is used for NTSC DVD playback.

5. In the Start field, specify the start time.
6. In the Timecode field, specify the duration of the colour source that you want to generate.
7. To generate audio with the clip, select the number of audio tracks from the Track box and then select a frequency from the Frequency box.
   NoteSelecting Silence will create audio tracks with a flat waveform.
8. If the frame mode is set to Colour, select the colour for the frames using one of the following methods:
   • Click one of the colour pots next to the Colour mode button to transfer that colour into the current colour pot.
   • Click the current colour bar to access the colour picker. Use the colour picker to create the current colour. See Picking Colours.
9. By default, the result clip will have the same resolution as the project default resolution. To specify an alternative resolution, click Res.

   The Resolution controls appear.

   
   

   (a)  Width and Height fields  (b) Resolution Presets box  (c) Bit Depth box  (d) Scan mode box  (e) Aspect Ratio Presets box  (f) Aspect Ratio field  

10. Specify resolution settings for the result clip using the Resolution controls.
11. Click Resolution to exit the Resolution menu.
12. Select the destination for the generated clip.

    The result clip appears in the selected destination.

Once you create a colour source or colour bar clip using the Colour Source controls, you can use it as a virtual source. See Virtual Sources.

To save a custom colour:

1. With Video selected from the A/V Tools box, click Colour Source.
2. Click the Source colour pot to open the colour picker.

   
   

   (a) Colour palettes  (b) Source colour pot  

3. Set a custom colour.
4. Click and hold in one of the colour palettes to store the custom colour.
