EX3 - Seeing Rolling Shadows In Some Shots
Once in a while I get shots, and I don't know how else to describe this, that have what appears to be a rolling shadow(s) in the brighter areas.
Shooting 1920x1080-30p @1/60 shutter speed. What I am doing wrong? |

Jay,
I'm sure you know a picture is worth a thousand words. In this case maybe a small video sample. |

I have seen the same in my footage in the last couple of days and I suspect it is a problem with my new Letus. Are you using a 35 mm adapter?

Own the camera for a year and have never seen this.
The only artifact I've seen that has a rolling effect is the rolling shutter under certain fluorescent lighting. This is expected. Please point to the examples you've seen here. |

When I saw the problem, I dumped the files. I'll try again tomorrow and post something.

I've tried uploading a clip to Vimeo, but it looked like garbage. So much so you couldn't see the shadow flutter (I deleted it).
As HD is totally new to me, any help would be appreciate (using Vegas Pro 8). Thanks! |

Odd.
Vimeo is actually really good. Also, it even allows the HD version to be attached. You should have no trouble showing video quality on vimeo. I've only used vimeo once, but it worked well. SONY PMW-EX1 Arizona Renaissance Festival on Vimeo |

Steve, I'm not blaming Vimeo! It's all my doing, no doubt. As I said, this HD format is totally new to me... like starting over.
I'm sure I did something, or failed to do something, that created a crappy video file. |

Update
I tried shooting some additional footage (nothing fancy or "beautiful"). The fluttering seems to only show where electric lights (incandescent) are shown. However, it only appears at the 30p frame rate at 1/60 of a second. I also tried 24p at 1/48 and 60i at 1/60. There were no flutters.
So what is it about 30p at 1/60 that creates these flutters? |
