This is highly dependent on you system resources, CPU, memory, disk I/O. If you are using a high compression codec with a high bitrate, then you need a fast CPU or you will lose frames, if you are using low compression, then you need fast disk I/O. Usually, in the case of guvcview at least, a good test is to disable audio and setting the stream format and the video codec to MJPG. This doesn't require any software compression, so if you still experience a high frame drop then most likely the problem is with disk I/O speed. Any other codec lfv, wmv, mpeg, mp2, mp4, can stress the CPU quite a lot, so try tweaking the codec options and the resolution (by lowering the bit rate and resolution you also reduce cpu requirements on the expense of video quality) On a side note I also own a sphere AF and can save a mp4 video with mp2 audio on guvcview at 640x...@25fps with the standard codec options. ( Mobo GA-X48-DQ6 with Q9300 o...@2,8 Ghz + 4Gb r...@900mhz + GF8800GT) Best regards, Paulo
