Would that counter be SMPT TimeCode, such as 00;00;00;027, counting either up, or down, or say 5, 4, 3, 2, 1?
For the "bars," are you referring to, say Color Bars, or a custom graphic?
Would this be for an Intro, or be superimposed over Video footage? If only for an Intro, then maybe there are some stock footages of various "counters," like the old movie countdown Clips, where the seconds are counted down, and often with a circle forming and disappearing to start over again.
For the former, if an SMPT TimeCode is required, you could do this easily (along with almost any "bars") in Adobe After Effects.
If it's a simple countdown, then one could do that with 01 sec. Titles in PrE, and one could also animate a "bars" graphic, to grow (Motion>Scale), and shrink.
Good luck,
Hunt
