record with delay winXP camtasia studio

Post by Archiflex »

Hey folks.

I am currently running a WINXP SP3 Version in linux host and encounter problems with screen recording using camtasia studio.
I thought this might be a reason to post in their forums, but i don't think that they may have any clue about virtualization purposes so i landed here.

When running directly on a XP machine it all went fine so far. Same hardware etc. developed a nearly perfect result. Anyway, since this is only a virtual machine, it started to lag by the time, so that my voice is always a few secs ahead of the picture it's related to. It may come from RAM, but both linux and windows are running just fine and don't actually lag, not even during the capture.
This might be a windows related question as it may exist a workaround or something but i wondered how that can be where all other my machines have worked fine so far.

Installation of Windows is Fresh. Installed all updates and stuff...No other aplications are running during capture (not even beeing installed).
The VM is connected to 1024MB of my ~2GB RAM and seems to use them as it should. I did not install the microphone drivers as they r included in an usb webcam-software package i did never had to install before to neatly record sound (well, at the time im downloadeing them..300mb...wtf)...Linux system is up to date.

This is more or less an information gathering thread about how that can be than a support question because i dont see this perfectly solved unless i reinstall XP directly on my real machine. Nevertheless, maybe there is a known workaround or we gonna find one together.
May it help to give the machine less RAM (so that linux stays calm during virtualization process?) or do you see the problem somewhere else (more driver- /windows related) that would be of interest

Greetings and blessings,
Archiflex

Edit: Driver Installation causes System to restart after bluescreen without having finished...Don't think it's better now ;)

Your virtual machine is using virtual hardware, including a virtual graphics card which is not as powerful as an actual graphics card. Virtual machines will never be as powerful as the host, specially on the video side. Applications that have high requirements on the GPU (drawing, 3D, games, video) are expected to not work as good as on the real hardware.

That being said, why do you need to do the recording from within the guest? You could use the video recording feature of VirtualBox. Never had any problems with it as long as the host is happy.
