- The result of recording is a 'black screen'
Disable overlays by setting the Overlays: Disable mode on Video page.
You may disable overlays on the session level or permanently. If you choose Overlays: disable (session)
you should start ScreenVirtuoso before the Media Player/Browser.
If the result movie is still a 'black screen', turn off the hardware acceleration:
Windows 2000/XP (classic view):
- Go to the Start Menu and select Settings/Control Panel.
- From the list view, select Display Properties and select the last page titled Settings.
- Find the Advanced button and then choose Troubleshooting.
- There you will find a slider control for hardware acceleration. Move that slider to None, then click the OK button.
See our comments about overlays in Online Help.
- Video & Audio are not synchronized.
It seems your audio card skips some audio samples for some reason.
It results in synchronizatyon problems (audio is shorter than video).
Try to increase an audio buffer size on Audio page.
Click >> button to aceess additional audio parameters and make audio buffer larger.
If you record streaming video, make sure a Media Player synchronizes audio & video because of ScreenVirtuoso records what it 'sees and hears'.
- ScreenVirtuoso does not record sound
1. Make sure the Record Sound option on Video page is checked.
2. Make sure you choose a valid audio input: See this Picture
To capture sound, coming from other application, you need to set the Mixer as audio input.
Also make sure a valid audio device is selected.
- Bad audio quality
If you record sound, coming from other application, make sure the audio input is not a microphone! See this Picture
- Sound is muted or almost inaudible
Check your sound card settings. Make sure the Mute buttons are turned off. Also check the
recording volume on Audio page.
- Video is choppy
This is a performance problem.
It seems a power of your computer is not enough to record a given screen area at a given FPS (frames per second).
Use the Test button on Video page to evaluate a performance (real FPS value).
See the Performance article to learn more.
- How can I record videos from DVD ? Media Player can not play DVDs if overlays are disabled.
Some DVD players can play videos if overlays are disabled. For example PowerDVD.
In any case this is not a very good idea to record video from DVD by using ScreenVirtuoso. It is mainly intended
for creating demonstrations and tutorials. It seems you need another software.
The best FREE tool is Auto GordianKnot
To edit your video clip (AVI) you may use FREE VirtualDub video editor.
- DivX codec does not work
DivX / XviD MPEG-4 codecs require a screen area alignment.
Go to the Screen page, click the More button and set 8 in the Alignment field.
Then try again.
- FLV/SWF video is to large
1. Try another video compressor. Use Demo (lossless) for demonstrations/tutorials and
Movie (lossy) for movies.
2. Reduce a bitrate value (video quality)
3. Reduse a video size ( Width x Height )
