Why would you need to flip the monitor in this configuration?

 

Chris

Since the camera is upside down, your X and Y axis' will be flipped, so that left is right, right is left, and up is down, and down is up. You need to invert and reverse the image or else you'll be operating completely backwards.

i don't get it. If you flip the entire rig as described, without using a camera low-mode bracket, the monitor is physically "flipped" in conjunction with the camera. There is no further need to flip it electronically.

 

It's a headflip, whever.

If you have a video camera, turn it upside down and look at the monitor. That might answer your question.

Respectfully, no.

 

In inverting the sled for a quickie low-mode (without remounting the camera on a low-mode bracket), there is no need to electronically flip the monitor.

 

That the image will need to flipped in post because the camera is recording uside down is clear.

 

Try it!

If you want to see the image right side up then you need to flip it on your monitor. Otherwise the image will be upside-down. I'm not sure why you think this wouldn't be true. The camera is upside-down, obvously the image will be too.

Brad, you are also rotating the monitor around its axis to get a clearer view of it and so needing to flip it. I sometimes do upside down low mode both ways. If in a hurry I simply flip the rig and tilt the monitor in a little. since the image is upside down on an upside down monitor it looks to me the right way up. Othertimes with more time I lenghen the whole centrepost, reposition my monitor on the lower (now upper) post and rotate it around so the monitor is above its own bracket. Then I need to flip the X and the Y on my monitor.

 

Is it just me or does the 435 chew up the film more frequently when upside down?

Brad, Chris,

 

I think Chris is leaving his monitor upside down (LCD?) for the swap to low-mode so the picture is now correct. Brad is flipping his monitor to be upright (necessary with most green screens and most monitor brackets). Since Brad's monitor is upright and the camera is upside down, electronic inversion is necessary.

 

Right????

Exactly. I didn't think of the LCD being upside down. Makes sense.

Yeah, but in this scenario the monitor will also be upside down, If you have an upside down camera and upside down monitor looking at the image it will appear to be the right way up, correct?

Hi John,

 

This post became confusing because of a misunderstanding between Brad and me. He assumed that the monitor would be remounted so that it would be right-way up on an inverted rig. I assumed that the sled would simply be flipped such that everything would be upside down. These are different practises dictated (as pointed out by Thomas and Alec) by different monitors and/or their mounts. You are, of course, right to say that in the second case the image will appear right-way up. If the camera and monitor are in the same orientation the image will appear "right". When you roll a sled such that the horizon image is off with respect to the monitor, it nonetheless remains parallel to the real horizon, and will remain so no matter how far you continue the roll.

 

Inverting one component relative to another requires that you electronically flip the image so you can navigate without giving yourself a cerebral hernia. If you have a non-flipping monitor, you'll encounter difficulty on a par with sticking wet spaghetti up a cat's arse.

Chris...

 

Now you've done it!

 

I can't get that picture out of my head.

 

 

Thomas,

 

If you are using the SL-cine 435 Steadimags it will chew some celluloid even right side up... I don't want to imagine upside down. Film Cameras were never designed to roll/run upside down... Most of them will do fine with extreme tilts and a roll, but anything longer is pushing it.

 

 

Fly safe,

Hmm, I've never heard of a problem running a film camera upside down. I've run Arri 3's, SR's, and 435's upside down and never had any problems.
