The Vertical Hold effect scrolls the clip upward; the effect is similar to adjusting the vertical hold on a TV. You cannot apply keyframes to this
effect.
Videomerge
The Videomerge effect automatically determines the background of the selected clip and makes it transparent. Video or image clips on the tracks
below it become visible through the transparent areas. If you want a different color to be transparent, select the Select Color option, and choose a
different color in the clip.
For best results, when shooting video that will use transparency, do the following:
Create a strong (preferably dark or saturated) solid, uniform color background to shoot against.
Make sure that the background is brightly and uniformly lit to avoid shadows.
Avoid skintones and colors that are similar to the subject’s clothing or hair color. (Otherwise, the skin, clothes, or hair will become transparent
too.)
Videomerge options
Click if you want to specify a different color as transparent.
Click the color box to choose a new color from the Color Picker, or click the eyedropper, and then click a color in the clip. To use this
option, first select Select Color.
Choose from Soft, Normal, or Detailed to specify the softness of the edges created by the transparency.
Specifies the color range that determines transparent areas in the clip. Dragging the slider to the right increases the color range so that
more similar colors become transparent.
Audio effects
Balance
The Balance effect lets you control the relative volumes of the left and right channels. Positive values increase the proportion of the right channel.
Negative values increase the proportion of the left channel. You can use this to compensate, for example, when the sounds coming from one
channel overpower those from the other.
Bass
The Bass effect lets you increase or decrease lower frequencies (200 Hz and below). Boost specifies the number of decibels by which to increase
the lower frequencies.
Channel Volume
The Channel Volume effect lets you independently control the volume of each channel in a stereo clip or track. Unlike the Balance effect, Channel
volume doesn’t automatically reduce the volume of one channel when you raise that of the other. You might use this, for example, to raise the
volume of a voice in the left channel without diminishing the volume of a voice in the right. Each channel’s level is measured in decibels.
