Where do i get a “white circle” for lip-sync test?

maybe you should add a little white cow on that frame!
might get a little laugh from the technicians

I have been using colour bars on 1 frame for the past few weeks
all you need is something which is noticeable compared to the black frames around it. this was to check sync on upconverted SD to HD material (lots of frame delays can happen with upconversion. a pop 2 sec before programme start can be used, I know an audio mixer friend who says 10seconds. they have a nice explanation as well in the new
workflow manual.pdf on the apple support site

and a beep on every single channel of audio which is being used at the hz rate you have been asked for

when I have been checking synch I also found outputting a countdown clock and asking a Kona card to output quicktime timecode overlays was useful as I could see exactly from the tape how many seconds it was off, it is useful to recapture from the tape to properly check this however

meant the FCP manual
page 419

link on the support part of the apple site

thought the other link was useful however, some nice things in the workflow pdf

think i have been reading too much in the past week

useful manuals

page numbers I listed maybe off topic though, sorry
