Tiffen UltraBright Image loss
Posted 08 May 2009 - 10:23 AM
I recently finally had some downtime and had the monitor checked by TIFFEN and they couldn't find the problem (curious I must say, seeing as they built it!!) Have any other owners of the UltraBright seen this and if so is there a cure?

Did you say that you have had the problem on all HD camera's?
I am not sure how to fix it either. Other problem becomes that if you use your framline generator, you are actually masking that much more of the area off. But You really do need to use it Because if the frame is dark along the edges or at the top or bottom you arent really sure where your frame ends and where its just dark monitor.
I am using the UltraBright 2 while mine is repaired and found that there was still a little bit of an issue when I took signal off the Panavision Box with some toggles set wrong (my DIT fixed it and I didnt really have the time to pay attention to what he did). Also it was fixed by coming out of the HDSDI port on the dumb side power panel. In the end, its all good coming out of that port, into my Decimator, into my sled video distro (on topstage) and going into the Composite channel of the UB2. I hope that it works that well when I get my monitor back.
I will try to pay attention better Iain when I get back to work, and will try to report back once I have my monitor back and can compare. I would like to say that Frank and Michael Craigs over at Tiffen were stellar today in helping me get my prep done so I can start my job on Monday. Thanks and big kudos to their support.

On the UB2 monitor via the menu there is an "UNDERSCAN" mode that allow you to see the picture full-raster. That should cure your image "edge" loss and the frame line issue. Then if you need to move it around a few deg. you can do it easily via the manual sizing mode. I can go through the actual menu on Monday and report back as to exactly what page to find the UNDERSCAN mode but it is very easy if you just look for it. HA HA...that said I overlooked it the first time as well.
My U2 has been very, very solid. An excellent sled in my opinion.
I am somewhat happy with the monitor but still on the lookout for this new OLED technology...but most important to me is an on screen level that works with ANY SLED with an HDSDI signal. I wish Bubb's level would work with HD. Then I would LOVE my monitor as well. Because it does not work with HDSDI overlay level I tend to use my monitor in NTSC mode. It is a bit of a bummer...So far the only one I know of doing this is the Transvideo system.
I agree that Michael, Dan, Robert, Peter and Frank have bent over backwards for me with customer service. I can't say enough good about them. Keep it up Tiffen!

The U2 sled is pretty remarkable. Congrats on that.

Correct... it does not have a specific menu that does it. You can go through the scaling menu and shrink the image to the minimum size on the UB1 to see it full raster. As I am trying to remember... it depends on the signal sent to it. It always seemed to come up fine with a film camera's video tap but not so good when sending it a down-converted signal from an HD camera or from something like a BetaCam. It seems that the full 1:78 image from most modern cameras was missing a few lines in the NTSC world when looking at the 16x9 letterbox feed on the 4x3 monitor (specifically on the sides).
The best way to see what your monitor is actually seeing is by shooting a REAL framing chart.
