HD100 Flicker issue

[sonisfear]

To give you a little back ground I was HDTV shopping and found that all the TV's I tried there was this unusable flicker with the HD100. I would not get this flicker in Native mode.

This was weird to me because the same footage didn't do this in post nor do I remeber it doing that in the store on the expensive HD ref monitors.

At first I thought it was the cam but as I started testing again I found that most of consumer TVs don't handle the 720p well but was fine in 1080I upconverted.

Its curious that the problem didn't occure with native mode.

I think the Tv's I was testing ($400-$800 26"/30" trying to save dough:^) don't like the 30 frames in 720P mode.

Anyway isues is solved..I think....

One of two things you are seeing:

If the flicker wasn't consistent, but phased on and off, and you were in a box store like Best Buy with flourescent lighting, you may be experiencing a sync phase problem with 60Hz Flourescent lights (you're in North America right?)

Put your shutter in to "variable" mode instead of "step," and then set the shutter speed to 59.94Hz to solve this problem.

Or

You may be seeing the "stutter" associated with progressive CRT displays.
We are so used to watching interlaced television (even when 24P is pulled down into 60i) that when you see true progressive displays of progressive signals it appears to flicker like a movie projector with a single shutter.
This is what happens to me everytime I work with a Sony F900 and HD displays. It takes a few minutes, but your eyes and brain adjust and then adopt the persistence of vision for progressive.
When you switch to 1080i playback mode of output (doesn't work for live signal) and the HDTV is set to interlaced (Toshiba TVs call it "Video mode" (interlaced) as opposed to "Film Mode" (progressive) the signal should look more "normal" to you, with the progressive signal embedded with a pulldown in the 1080i.
