No usual 2GB limit in SV 3.0 and higher! The maximum AVI file size is limited by the disk structure (4 Gb for FAT32, no limit for NTFS). Also no limits for the recording time.

To reduce a file size for demonstrations/tutorials, follow these simple rules:

1. Set the FPS=5-7. Usually it is enough for this type of video
2. Use the 'FM Screen Capture' codec. It is highly optimized for creating demonstrations/tutorials.
3. Set lower 'Key Frame' value.

Do not use our 'FM Screen Capture' codec for movies. Use XviD / DivX codecs instead.

To disable this window click the Configure button on Video page, then click the Other Options button, and uncheck the Display encoding status check box.

ScreenVirtuoso allows you to record sound and synchronize it with video.
Make sure the Record Sound option on Video page is checked.
To record sound coming from other applications/internet choose a Mixer/What U Hear/Wave Out as the audio device/input on Audio page.

Not all third party codecs can work with ScreenVirtuoso. By default, a codec combo box displays only 100% compatible codecs.
We advice you to use our FM Screen Capture codec for demonstrations/tutorials and XviD MPEG-4 codec for movies.
Usually this is enough.

See the FM Screen Capture Codec article to learn more.

Internet, Media Player, webcam and more videos. We do not advice you to use ScreenVirtuoso to record video from DVD. See the Troubleshooting FAQ to understand a reason. Make sure the overlays are disabled on Video page (XP and lower) before you start the recording.

Try to turn off the hardware acceleration. See the Troubleshooting section for instructions.
In some cases the hardware acceleration affects the CPU usage dramatically!
Note, ScreenVirtuoso also uses a lot of CPU if you record a large screen area at high FPS (frames per second).
It also depends on power of your system. See the Performance article to learn more.

You do not need a special hardware. But systems with a low performance may result in a low record rate (frames per second). See our Performance article to learn more.

Vista, XP, 2000, 98, Me, 256 MB RAM. If you have problems with a new SceenVirtuoso 3.x-4.x on old systems, try the old version.

The result FPS value depends on many things: hardware performance, size of area to capture, video codec and more. Click the Test button on Video page to evaluate the performance. See our Performance article to learn more.

To reduce a file size, follow our advices:

1. Use the Screen Video lossless codec for demonstrations/tutorials and the H.263 lossy codec for movies.
2. Reduce a bitrate value for video/audio.
3. Reduce a video size (Width x Height).

Try to execute the Tools | Restore Default Settings command.
If it does not help, please contact us.

When a frame is saved in AVI file, it can either be saved as a full frame, or only partially as a difference to the previous frame. The key frame rate specifies how often full frames are written to the AVI file. A low value means you can fast forward/rewind to a particular frame in your movie much faster. But it also means a higher file size.

Codecs that utilize temporal compression store only differences between frames. When the frame differences are small from frame to frame, it makes the file size much smaller (demo, tutorials). Note, not all codecs support a temporal compression. FM Screen Capture Codec supports it. Key frame and Temporal Compression are related concepts (see previous FAQ).

Video quality depends on selected codec. Try to configure codec by clicking the Configure button. Our FM Screen Capture Codec is a lossless video compressor. Quality always equals 100%. Video quality also depends on media Player mode. For example, overlays make video worse. Turn overlays off in Media Player if it is possible.

Disable overlays by setting the Overlays: Disable the Hardware Acceleration mode on Video page.
If the result movie is still a 'black screen', turn off the hardware acceleration (Windows 2000/XP):

- 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.

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.

1. Make sure the Record Sound option on Video page is checked.
2. Make sure you choose a valid audio device/input on Audio page.
3. If you still have problems, please read this article.

If you record sound, coming from other application, make sure the audio input is not a microphone! More...

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 value (frames per second). Use the Test button on Video page to evaluate a performance (real FPS value).
See the Performance article to learn more.

DivX / XviD MPEG-4 codecs require a screen area alignment.
Go to the Screen page, click the More button and enter 8 in the Alignment field. Then try again.
