Synchronizing audio and video
If your video has been opened from a slow device, such as a CD-ROM, DVD-ROM, or network drive, Sound Forge software may have
trouble accurately playing back the audio and video in sync. You should always copy your video files to a fast hard drive. Listed below
are a few tips that can help when trying to synchronize the audio and video:
•
After assembling or editing the audio you wish to use with your video, place markers during video playback to correspond to any
major synchronization points. You can locate a particular frame by dragging the cursor along the audio if the Video Preview
window is open (from the View menu, choose Video Preview) or the Animate Video Strip option is enabled (from the Options
menu, choose Video>Animate Video Strip. After primary locations have been identified, drag your audio to these markers to mix
and paste audio.
•
Features such as Insert Silence, Delete/Clear, and Time Stretch are commonly used to correct synchronization. Another useful trick
is to create a region representing the offset between a video frame and audio event. Then you can enable Lock Loop/Region
Length and drag the offset region to a preceding silent section. Use the region as a template for adjusting the audio stream
length—either copying and pasting to insert time or deleting to remove time.
