If you plan to create film output from a sequence, you may want to add a counting leader. A counting leader helps a projectionist verify that audio and video are working properly and are synchronized. You can create and customize a universal counting leader to add to the beginning of a project. The leader is 11 seconds long.
You can customize a counting leader clip by double-clicking it in the Project panel.
You can create a one-second clip containing color bars and a 1-kHz tone, as a reference for calibrating video and audio equipment.
Some audio workflows must be calibrated at a specific tone level. The default level of the 1-kHz tone is -12 dB referenced to 0 dBFS. You can customize the tone level to match your audio workflow by choosing Clip > Audio Options > Audio Gain with a clip selected. If you select the bars and tone clip in the Project panel, you set the default gain level for new clip instances. If you select a clip in a Timeline panel, you change the level for that clip instance only.
Franklin McMahon created this video tutorial on synthetic media: transparent video, color bars and tone, and color matte on the Layers Magazine website.
Premiere Pro has HD color bars that comply with ARIB STD-B28 standard for calibrating video output. Synthetic media also include a 1-kHz tone.
For HD bars and tone, do the following:
- Choose File > New > HD Bars and Tone.
- A dialog launches with settings based on the existing sequence. Change settings, or click OK to accept the settings.
Empty areas of a track appear black if no other visible clip areas are present on underlying video tracks. If necessary, you can also create clips of opaque black video for use anywhere in a sequence. A black video clip behaves as a still image. To create a clip of a different color, use a color matte. (See Create a color matte.)
If necessary, in the New Black Video dialog box, set Width, Height, Timebase, and Pixel Aspect Ratio to match these settings for the sequence in which you will use the black video clip. By default, the duration of the new clip is set to five seconds. Click OK.
You can change the default duration of black video clips and other still image clips in the General pane of the Preferences dialog box. For more information, see Change the default duration for still images.
Transparent Video is a synthetic clip just like Black Video, Bars and Tone, and Color Matte. It comes in handy when you want to apply an effect that generates its own image and preserves transparency, such as the Timecode effect or the Lightning effect. Think of Transparent Video as “Clear Matte.”
Eran Stern explains the purpose and use of transparent video clips in Adobe Premiere Pro in this video.
You cannot apply just any effect to Transparent Video—only those that manipulate the alpha channel. For example, these are some of the effects you can use with a transparent video clip:
