Re: Screen Recorder does not compress sound
There are a lot of programs in Internet, which can compress sound. I prefer to use Sound Forge for compressing sounds.
Ann, my blog is here
Re: Screen Recorder does not compress sound
This has nothing to do with the problem. The question is using Screen Recorder to record screen activity, image + sound. Both are stored in a AVI (Audio Video Interlaced) file, but this file is huge if sound is activated, because the sound is uncompressed. Sound Forge cannot compress an AVI file. If I am wrong, tell it, I would be interested.

Re: Ultra ScreenRecorder
No playback is perfectly OK (image and sound). The only problem is that the file is big because sound is uncompressed.Playback is just a blank screen?
It works well, yes, as camStudio (and much similar) but with the same problem : screen update is slow, and on my PIII the mouse is very slow. ScreenRecorder is MUCH faster because of the use of the video driver.this works well

Re: Ultra ScreenRecorder
I am using ScreenRecorder and I can record the video without problems, but when I select Enable Record Audio, I can record the audio but no the video in the AVI file.
What is the optimal combination for audio and video codecs?

Re: Ultra ScreenRecorder
audio is raw pcm -> big file
video: use an encoder that support size end depth, i have good results with divx
After recording you need to make the file smaller (audio stream is huge)
Use a opensource tool like virtualdub, this can compress the audio and generate a divx+mp3 file.

Re: Ultra ScreenRecorder
I had this problem in the beginning. I discovered that reading the file in a different video player, the video was OK. I don't remember which video player I was using but it was not windows's standard. Try with a different player.I am using ScreenRecorder and I can record the video without problems, but when I select Enable Record Audio, I can record the audio but no the video in the AVI file.
This is exactly the way I used to solve the problem.After recording you need to make the file smaller (audio stream is huge)
Use a opensource tool like virtualdub, this can compress the audio and generate a divx+mp3 file.
What is confusing is that Video Recorder has audio options for compression. But presently they don't work.
1) open the file in virtualDub
2) In video menu, choose "direct stream copy"
3) In audio menu, select "full processing mode", then choose "compression" and select the parameters you want.
4) in the file menu select save as AVI, you are done in a minute.
You can also change the video compression if you like.

Re: Ultra ScreenRecorder
Rudi De Vos,
Is this product discontinued?
If not: Ultra ScreenRecorder (? version: downloaded approx 2 weeks ago) is not able to record SketchUp's 7 workspace area. ScreenRecorder settings are default. Capture was done in "whole screen" mode (if capturing screen segment then resulting output video is distorted and very slow). One of default encoders available on Windows XP SP3 x32 was used for the capture.
p.s.: CamStudio (version from camstudio-org) captures SketchUp's 7 workspace area well.

Re: Ultra ScreenRecorder
I downloaded Ultra ScreenRecorder from http://www.uvnc.com/screenrecorder/ . During installation 3 drivers were installed. Not sure whether they were Rel1.00 or Rel 1.01 or something else.redge wrote:lait

Can you tell me where can i get Rel1.00 or Rel 1.01 and how to install this driver (standalone .sys file?) ?
Re: Ultra ScreenRecorder
On the general download page
http://www.uvnc.com/download/index.html
The screenrecorder and required driver are listen in the
"Download UltraVNC screenrecoder" part.

Re: Ultra ScreenRecorder
So, i downloaded package ultravnc_tools_setup.exe and driver.zip from provided page. Firstly tools were installed (full installation), resulting in 1 new service on my system and 2 drivers under \system32 (vncdrv.sys and vnccom.sys).
Unpacked driver.zip. If i launch install.bat nothing happens (no registry keys being overwritten, nor drivers vncdrv.sys and vnccom.sys under \system32 and %programfiles% either).
If i launch install_silent.bat then registry key for vnccom.sys being modified and vnccom.sys under \system32 (or %programfiles% ?) is modified either.
How to install needed driver(s) correctly?
...By the way please fix uninstaller because it fails if UVNC service is running or uninstalled. OR place uninstall_note.txt which contains instruction:
* you should not uninstall sevice prior running uninstaller;
* you should stop UVNC service manually prior running uninstaller.
In order to cleanly uninstall this package i ought to go through installation-uninstallation couple of times.

Re: Ultra ScreenRecorder
when i push the framerate to 15 and use the xvid codec, it records, though i cant see it, which is certainly due to the driver fail to install..
since everytime i installed the driver or the ultra tools suite, in the end a window told me that the driverinstall failed ..

Re: Ultra ScreenRecorder
I have Windows 7 64 bit version. This ScreenRecorder won't work on it, because the installer has 32 bit driver only, and it can't installed on 64 bit. I have installet UltraVNC 64 bit, and it installed 64 bit version of video hook driver. But it seems ScreenRecorder can't use the 64 bit driver.
It is possible to create a 64 bit version of ScreenRecorder?
And there's an other problem: ScreenRecorder automatically installs a service, but it overwrites UltraVNC's service. If i select in ScreenRecorder's setup to do not install the service, it doesn't install the recorder app.
Is it possible to rename the ScreenRecorder's service, or change sets in the installer?

Ultra Screen Recorder + UltraVNC
Can Ultra Screen recorder and UltraVNC be installed and both work on the same machine?
I have been unable to get this to work. It seems one overwrites the other.
