Delayed video and audio while previewing
There is a small delay, of less than a second, between the time that video and audio
is received by Video Recorder, and the time that it appears in the Blackmagic Video
Recorder software on your computer display. The delay occurs regardless of whether
video is being recorded to the hard disk or not. The delay is normal and occurs because
it takes a moment for the Video Recorder hardware to encode your video and audio
into high quality, H.264 compressed movie files. For this reason, it is best to use the
video preview window in Blackmagic Video Recorder to determine when to start and
stop recording your video. If you were to rely upon the built-in viewfinder in a video
camera, you might start and stop the recording a little earlier than desired.
Jerky video preview while recording
On older, slower computers, you might observe that the video preview appears fine
before recording starts but looks quite jerky when recording video to the hard drive.
This is because older computers may not have enough power to preview the video
smoothly at the same time as writing the video to the hard disk.
The jerky preview does not affect the quality of the video recorded to disk. When you
open the recorded video, it should play back perfectly smoothly.
