Audio-Video recording

Using this function you can capture video/audio during the performance.

Technical Notes

  • Only Audio recording
    You can use the characteristics Hardware of your sound-card to record in PCM-WAV format. And later you will convert in MP3 or whichever other format using "Converi" function of Windows "Sound recorder" or whichever other program of conversion. You can also record a "Standard" Audio CD using a program released together to your CD master (ie. Roxio, Nero, etc).

  • Video/Audio recording
    You can record the video using the same WebCam that already used for chat and audio using your sound-card. Captured video is recorded in AVI format using compression Video-Audio codecs, therefore is editabile and convertibile using whichever video editor  (ie. ®Microsoft Movie Maker)

  • Audio-Video recording is available in ADVanced and PROfessional  versions while it is demo (time limited to 15 sec.) in the Junior version.

  • KarAll is a "CPU intensive" application. Means that several functionalities need of much CPU-Time to works. New recording functions also need very much CPU-Time. We executed some tests for only Audio recording using ®Pentium-III and it's ok. But for Video recording functionalities must use a ®Pentium-IV PC, at least of 2,5Ghz if use "Live-View" function. We advise you to activate the "Task manager" during the tests; if CPU-Time-used is constantly over 75% the functions could have problems and loss  part of the captured Audio-Video data or  slowing or stop 'application. Moreover, if the captured video seems type "Slow-Motion" don't depend from program oy from operating system, normally it depends on the WebCam that does not have the characteristics to captuire a sufficient number of photograms for second (norm. 15 fps); you can check for this problem from capture  statistics if a high percentage of photograms discarded.

  • Recording functionalities depends completely from some Windows modules, drivers of the Sound-card/Webcam and Audio-Video "Codecs" installed on your PC. In some cases could be  errors for incompatibility between they or for not Windows certification. We have noticed that  several codecs (MP3, DivX, XVid, etc.) are usually more stabler in Windows XP/NT/2000 rather than Windows 95/98/Me. In some case you can try to solve problems installing newest version or changing combination of Audio/Video Codecs.

  • We advise you to use a little time bit first time you use this functionalities to "Tuning" system
    Don't worry, it's not very difficult !
