Webcam C615 cannot go above 15 FPS

[ Edited ]



I've recently bought a C615 because it seems to be able to run 30 FPS at 720p resolution.


However it seems to block the fps at 15 whatever I do.


I know someone that is recording 720p 30 FPS videos with the logitech webcam software.


I've tried some third party software to record. However even if you set the framerate at 30, the real framerate is lower.


My computer specs are :


Core2 Quad 2.4 GHz


geforce 8800 GT

Windows 7 64x


I load the logitech webcam software : Version 2.3, build 13.30.1396


In device info :


Device information

Firmware version : 7.0.1194

Firmware CRC : 0XE751

EEPROM version : 2.52

Sensor Type : 2.3


Driver information

Driver version : 13.30.1394.0 (how comes it does not match the build version found in Preferences -> About ... ? )


Then I go in quick capture and I set the following settings :


Resolution : 360p, widescreen

Follow my face : Off

RightSound : Off

RightLight : Off

AutoFocus : On

Exposure and Gain : Set to minimum.


Then I record a video and go to its properties :

Any idea why I just can not record any video at 30 FPS ?


Is there a way to know which FPS @ Resolution are physically supported by the C615 ?


Thanks in advance.

I've tried some third party software to record. However even if you set the framerate at 30, the real framerate is lower.

Please provide a sample video that illustrates this condition for evaluation.
