Color Block DB4 output flicker
19 February 2007
Although not noticeable live, in certain circumstances a flicker can be perceived on camera when using Color Blocks with High Definition or high speed cameras. This flicker can normally be resolved satisfactorily by camera adjustment, however Spectrum Manufacturing have developed a software modification to resolve this issue if camera adjustment is not possible. Only the following serial numbers are affected:
