- What is the maximum AVI file size ( time of recording )?
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 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.
We advice you to use a FREE XviD MPEG-4 video compressor: http://www.xvid.org,
Download.
- How to disable the XviD's status window ?
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.
- Does ScreenVirtuoso support a sound recording?
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 as the audio input on Audio page.
- Video codec does not work.
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 FM Screen Capture codec for demonstrations/tutorials and
XviD MPEG-4 codec for movies.
Usually this is enough.
- What is a 'FM Screen Capture Codec'?
See the FM Screen Capture Codec
in online Help for details.
- What kind of streaming video can ScreenVirtuoso record?
Internet, Media Player, webcam and more videos.
We do not advice you to use ScreenVirtuoso to record video from
DVD. See the Troubleshooting page to understand reasons.
Make sure the overlays are disabled on Video page before you start the recording.
- ScreenVirtuoso uses about 100% CPU!
Try to turn off the hardware acceleration.
See the Troubleshooting page for instructions.
In some cases the hardware acceleration affects the CPU usage dramatically!
Note, ScreenVirtuoso use a lot of CPU time if you record a large screen area at high FPS (frames per second).
It also depends on power of your system.
See the Performance page for details.
- Do I need a special hardware for ScreenVirtuoso?
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.
- What are the system requirements for ScreenVirtuoso?
Vista, XP, 2000, 98, Me, 256 MB RAM. If you have problems with a new SceenVirtuoso 3.x
on old systems, try the old version: Download
- What is the maximum FPS value (frames per second)?
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 page to learn more.
- FLV/SWF file is to large. Is it possible to reduce it?
To reduce a file size, follow our advices:
1. Use the Demo lossless codec for demonstrations/tutorials and the Movie lossy codec for movies.
2. Reduce a bitrate value for video/audio.
3. Reduce a video size (Width x Height).
- I can not run ScreenVirtuoso. Error message box appears.
Maybe our security code conflicts with other software installed on your system.
Email us and we will try to help you.
- What are the Key Frames? How they affect video?
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.
- What is a Temporal compression?
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 is not good.
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.
