you can’t go wrong with a second EX1, but you may find a great second hand Z1 or V1 that would work well

I know how long Convergent Design has been developing the XDR to unleash the possibilities within not only smaller video cameras but many professional cameras as well. I will be testing it very very soon as the first units are on the production line.
With any thing knowing how to make the most from your equipment is the key, overcoming limitations using either inventive shooting techniques and or with the addition of innovative new support gear that takes you beyond the limitations of the camera..
Having the ability to decrease the compression together with higher color space levels will produce a better overall image quality with any camera.
I believe you will find the XDR to be one of the best products in your kit.
Good Luck

How exactly did the clip change, by file extension? SMI maybe? You need to provide a little more information. You should copy the BPAV file on the card to a new folder as a precaution but I’m thinking you either have ran out of room on one card and the clip continued onto the other card or you have a clip that is larger than 4 gigs.

The EX series cameras are definitely capable of recording for any network broadcast. As far as HDV for broadcast goes there is a don’t ask don’t tell common philosophy, it’s all about the content. With any video format good photography skills make good images and IMO HDV is even broadcast quality if it is used correctly.
I would like to suggest a new product that I’m looking forward to adding to my inventory list that may be what you should look at first, it’s the Convergent Design XDR Compact Flash HD-SDI recorder. The EX series cameras and some HDV cameras have the HD-SDI uncompressed signal that can be recorded with less compression using the XDR, as you choose the compression level from HDV 25Mbps all the way to 160 Mbps All I-frame 4:2:2. There are HDV cameras with HDMI (another uncompressed HD signal) that can be converted to HD-SDI that can also use to produce unbelievable images. You may already have the camera you need and recording at a higher bit rate would definitely raise the quality of over it’s HDV compression. The XDR Nano will have the ability to use HDMI directly from the camera and should be available by the fall. The XDR should be available by end of summer.

One other thing to remember is to keep your subject as far from the green screen as possible, as your green screen will reflect green back to your subject making it more difficult during the keying process. If you are just lighting the Green screen with the Flo’s then just make sure and use the same brand and model. Color Temp and CRI levels aren’t really important as long as you are just lighting the green screen.
If you are lighting people with these flo’s then here is some information to keep in mind.
Fluorescent tubes come in a wide variety of not only color temperatures but various CRI ( Color Rendering Index) levels. You can look at the lettering on each tube that will tell you in most cases where the tube rates. A lot of tubes will have 70, 80 or 90 somewhere within the markings on the end of the tube. 70 CRI will have a higher green spike than 80 CRI or 90 CRI and they aren’t really good for lighting people. I would suggest you find tubes that have as close to 5000 or 3000 kelvin as possible and has a 90 CRI rating for the best color spectrum representation. Look up Vita-Light

Depending on the fixtures ballast type you should be able to find tubes that will light to the tubes capability or rating.
I found Philips T-8 tubes with 90 CRI in 3000k (TL-930) and 5000k (TL-950) kelvin temperatures that can be dimmed using the Mark X Philips electronic ballasts. Note the 9 is for 90 CRI and the 3 or 5 is for the kelvin degree. These tubes are beautiful and extremely color constant between tubes and tube sizes. The tubes you’ll find at the big box stores should give you some indications of how they rate.You may want to purchase some color corrective gel so you can add some blue to the tungsten units.

I believe you should use anything and everything you have and learn what works for you. I hope this helps you.Good Luck

I’m guessing here but you are most likely using USB from either the camera or a card reader and perhaps this machine has a slow USB port. Try coping the BPAV file to a new folder to the hard drive of the laptop or a firewire external then see how Clip Browser works. I don’t really know much about PC’s these days as I have been using a Mac for the last 5 years. This should give you an idea of the problem, if it is the same after this then it would seem the CPU is what you should look to next. I know there are big CPU differences with PC laptops. If you have the PCI express slot that the SxS card fits into you should find much better speeds using it.

The HD-SDI signal from the EX1 is before any compression. I’m sure the 50 Mbps setting would yield a superior image to the EX1 HQ record mode.
As to the run & gun, Convergent Design is working on a smaller second unit that will have only 2 cards that you can wear on your belt, it will also have HD-SDI & HDMI compatibilities for recording.
The price is a bargain for what you’re getting, low cost compact flash cards and lower compression result in higher quality video. You can purchase 32 gig cards for $150 that will record 100 Mbps all i-frame 4:2:2. So now your into extremely high quality HD recording for an affordable price. No one is going to sell a full raster HD camera for under 14K that can produce what you can get from the EX1 XDR combo.

I’m not sure a $6500 camera is the right tool to make big screen projects, unless you can record at a lower compression level. That is where the Convergent Design’s Flash XDR HD-SDI recorder comes in. With the XDR you control the compression level from HDV levels to completely uncompressed with future updates. It will offer 50 Mbps @ 4:2:2, 100 Mbps all i-frame 4:2:2 and up to 160 Mbps all i-frame 4:2:2 to begin with.
https://www.convergent-design.com/I believe this will be the perfect solution to your projects and maximize the EX1 CMOS system.

I believe you have clips that either were over 4 gigs or have crossed to another card.
In the case of a clip being over 4 gigs you will see the SMI file and perhaps 2 files that end with -1 then -2, highlight the clip and down in the information box, i believe under the subclip you will see a check box for these clips, make sure they bother are checked. If you have clips that have crossed to a second card you will need to add an end mark to the first half as if you were making a subclip.Good Luck
