Re: Waveform "ringing" issue in downconvert

It might be scaling artifacts... the higher-quality filters can introduce overshoot + undershoot / ringing. Maybe this is the cause?

The Teranex device might give you control over the filtering... extremely soft filtering shouldn't give you ringing. Although that's not really what you want... but it might be a way of checking to see that it's the filtering that's causing your "problem". But it's not really a problem... it's generally considered the correct way of making high quality video (because the alternatives are blurriness and aliasing, which are more objectionable).

2- You can always insert edit over your color bars. Though if QC is not dinging you for it then that may not be necessary.
