After more search video encoder take its source directly from sensor at 1280*720 aka 720p res.before to encode it aplly some heavy filters.maybe usefull by poor light conditions but in optimal ones it reduce spatial resolution too much and create some aliasing on lines and fine details.The results is video just a bit more detailed than a good 480p.here a sample of it in source code documentation :-------------------------------------------------------------------------------Name CX2341X_ENC_SET_DNR_FILTER_MODEEnum 155/0x9BDescriptionAssign Dynamic Noise Reduction operating modeParam[0]Bit0: Spatial filter, set=auto, clear=manualBit1: Temporal filter, set=auto, clear=manualParam[1]Median filter:0=Disabled1=Horizontal2=Vertical3=Horiz/Vert4=Diagonal-------------------------------------------------------------------------------Name CX2341X_ENC_SET_DNR_FILTER_PROPSEnum 157/0x9DDescriptionThese Dynamic Noise Reduction filter values are only meaningful whenthe respective filter is set to "manual" (See API 0x9B)Param[0]Spatial filter: default 0, range 0:15Param[1]Temporal filter: default 0, range 0:31-------------------------------------------------------------------------------Name CX2341X_ENC_SET_CORING_LEVELSEnum 159/0x9FDescriptionAssign Dynamic Noise Reduction median filter properties.Param[0]Threshold above which the luminance median filter is enabled.Default: 0, range 0:255Param[1]Threshold below which the luminance median filter is enabled.Default: 255, range 0:255Param[2]Threshold above which the chrominance median filter is enabled.Default: 0, range 0:255Param[3]Threshold below which the chrominance median filter is enabled.Default: 255, range 0:255-------------------------------------------------------------------------------This review sample seems to confirm lowest spatial resolution.I m not sure this is the values to tweak but sure video capability of our device is not fully exploited.dont know how to recompile them to do some tests.May someone can recompile them disabling all those filters and enable a better 720p output...edit: again workin on it to find a way to recompile it for disabling filters to do some tests
