I remembered reading about a kinda of fix for the strobe artifacts that you get on the ex1 if a camera flash goes off, I did a little search and could not find anything.

I think there was a plugin that you could use to cover it up i just cant remember what it was called.

anyone??
 
Ned,

You've been a respected voice of reason around these video boards for as long as I can remember. I know you're shooting an EX1, have you come up against any situation while shooting this cam that just wasn't going to cut it from a footage usability standpoint? I've torture tested it shooting all kinds of motion such as moving cars, normal action type pans etc, viewed it slowed it down in post (where it really used to show up with HDV for me) and I'm just not seeing a problem. The video appears cleaner then the HVX200 720p60 to me in spite of the fact that it shouldn't be given the long GOP/rolling shutter etc.
 
The strobe artifacts are the only one i have ever noticed, I have pushed the camera to its breaking point and its still better than a HVX.

Thanks for the kind words ;)

I've got one example that I utilized in an article and that I have on public folder on my iDisk. PM me or email privately and I can let you see the example. In this case, it was a strobe going off at the ice rink at Rockefeller Center while I was shooting 720p24 at 60 fps. When you view the clip, it just looks like a long strobe. When viewing the individual frames, you do see the effect of the rolling shutter.

I would not consider this shot ruined at all.

My b-roll comment was a bit sarcastic and tongue-in-cheek but in reality b-roll is the answer for just about any ruined shot ;)

Seriously... I think that rolling shutter effects are endemic to CMOS cameras.

I like the results from this camera... so much that I ordered an EX-3. I have some ergonomic and control issues with the EX-1 which seem to be remedied with the EX-3. I like the DVCPRO HD codec and the full 4:2:2 depth of the HVX. I like the sharpness of the EX-1 (and EX-3). Every camera and format has its issues. So far rolling shutter has not been a deal breaker to me but the time will come I'm certain that it will ruin a good shot. On the other hand, how many of us haven't ruined a shot due to some other factor.
