January 22, 2009 at 8:04 pm in reply to: CMOS chips- rolling shutter causing any ill effects for wedding videographers[Olly Lawer] “The EX1 will mainly be used to film weddings, where there may indeed be lots of flashes; however, if by turning the electric shutter off and shooting in interlaced, this solves the problem, then great.”
You’re worrying too much about this. It’s not a huge issue. With a CCD camera a camera flash will blow out one entire frame of video and you can’t see anything in that frame. With a CMOS camera only part of the frame will have the flash in it and a good portion of the time you’ll still be able to see what’s in that frame. So now you tell me which is more disruptive and obvious. Sometimes a recorded CMOS camera flash will be spread over 2 frames but sometimes not. It all depends on the timing of the flash in conjunction with the scanning of the CMOS chip because it’s scanned from the top down whereas a CCD is scanned all at once.
[Olly Lawer] “Does filming interlaced give similar results to progressive?”
Yes.
[Olly Lawer] “I know the shutter speed doesn’t stop any unwanted artifacts, but does shooting in other modes change it? i.e. 1080i compared to 720p?”
No, because it’s got nothing to do with recording format or frame size. It’s got everything to do with the way the CMOS sensor is scanned. I’ve recorded flashes in both interlaced and progressive and it always looks the same.

Rafael is in Bangkok at the moment getting the firmware upgraded on his EX1. He should be back home in Laos shortly.

I couldn’t agree more and most of the time this is true. However, there are some ethnic communities around here where I live that want camera gear to be as visible as possible and the more of it the better. It’s a sign of wealth and status to have camera cranes and such stuff in full view of the audience. Certainly not my cup of tea but to each his own. Choose your market and go for it.

January 18, 2009 at 12:37 am in reply to: Cleanest Downconvert from XDCam EX to DVC PRO HDHi Chris,
I convert HQ 1080p 30 EX footage to DVCPRO HD footage quite often.
- 1. new sequence
- 2. drag the DVCPRO HD stuff to the seq.
- 3. drag the EX stuff in. FCP will conform the footage to match seq. settings.
- 4. edit.
- 5. export self-contained .mov using seq. settings. Rendering or not beforehand is optional because FCP will render on export. If you render first then export you’ll have render files taking up space. Your choice.
- 6. If you want a 720p version of your project choose: Export Using QT Conversion. Choose 1280×720 DVCPRO HD and let ‘er rip.
I’ve been loving the result.

This is a really long shot but go to your control panel and make sure that everything to do with Universal Access is turned off. Everything. Cycle through the tabs to make sure.

Hi Kellen,
Are you sure you want to spend money on a RAID system just for archiving? Since access speed isn’t a factor with stored files why not just buy some USB drives and fill those up? RAID systems are more for editing multiple streams of video rather than archiving. And if you’re thinking of using a RAID setup for both editing and archiving that sort of defeats the purpose of having a separate raw file backup, doesn’t it?
There are lots of great RAID systems out there these days. Whatever you decide to go with give serious consideration to a turnkey system as opposed to something cobbled together from different manufacturers. The article below explains why:

Hi Ryan,
Welcome to Creative COW. Think of a BPAV folder as the new video tape. With it you can use it on both Windows and Mac platforms that are capable of working with EX footage. When you import from a BPAV folder using FCP’s log and transfer what you get can only be used by FCP and Quicktime Player.
Archiving your BPAV folders is a good practice to get into and the fastest way to do this is to copy the BPAV folder to a hard drive. There are a couple of ways to do this:
- 1. Connect your EX to your computer via USB. When the card(s) appear on the desktop open one and drag the BPAV folder to another attached device (like an external hard drive) to make an exact copy of the BPAV folder.
- 2. The smarter way is to use Sony’s Clip Browser 2.0 to copy the BPAV folder to somewhere else rather than just dragging and dropping in the Finder. The reason? Clip Browser will make sure there are no errors during the process. This is called “CRC Error Checking”.
Put each copied BPAV folder into a separate parent folder that you can name whatever you want. Usually the name will hint at when and where the footage was shot. Never change the actual name of any BPAV folder otherwise Sony’s Clip Browser or the Transfer Tool software will not see it.
To import video clips from any copied/archived BPAV folder simply navigate to it within the programs you usually use just as if the folder was still on the card.
