Shooting 1.5x Anamorphic on Red

[Patrick Hughes]

Hey Red Users! So I have decided to try out Anamorphics on my Gemini, I bought an Iscorama Pre-36 which is a 1.5x lens but here's where I'm running into problems. When I go into Red menu I'm only given the choice of 1.3x, 1.25x, or 2x anamorphic and various aspect ratios. So without being able to choose any of them values, should I just shoot in regular 5k and fix the image in post? Sorry I'm very confused, I'm also not sure if I should choose 6:5 aspect ratio or not, if I was shooting 2x Anamorphic the dimensions would be 7200 x 3000, 1.3x would be 4800 x 3000, but without a 1.5x option I'm stuck with 3600 x 3000. Any help would be great.

Thanks so much
Patrick

Full in camera monitoring and format support for 1.5X has been requested a few times. Up to RED now to implement it. There truly isn't a large volume of 1.5X anamorphic glass on the market (Yes I own two 1.5X however). But with newer 1.5X stuff coming from P&S and also the crazy 1.8X stuff and all that, there might be real reason to look harder at anamorphic support.

To that point, I shoot a regular spherical format with 1.5X and desqueeze via monitor to see what I'm doing. On monitors that don't support 1.5X, try 1.3X, it gives you a good idea of what's going on.

This raises a good point regarding the support for 1.5x, 1.8x going forward. P & S and Cooke and other lens companies all deserve it, yet I can imagine it all gets a little confusing depending on how the sensor size supports the particular anamorphic lens.

Not sure what is on the table with RED'S development and forward-looking support of anamorphic, but I believe we will see more and more anamorphic usage within a project, both wholly or perhaps for just some shots within a project.

 

[Phil Holland]

Perhaps. I love anamorphic, but percentage-wise it's still used incredibly rarely industry wide. However, now that a lot more anamorphic glass is here and more on the way, perhaps a new uptick in the look and trend. We'll see.

BTW ISCOs are actually more like 1.41x in actual use...

so even with 1.5x de-squeeze it will still be not on point so you may well go with 1.3 like Phil suggested

or...keep pushing (like I do since ages) to beg RED to implement a custom de-squeeze setting in the menu! ;-)

I know it's not easy to implement but it will be very very cool and very appreciated by many ana users like us.

... there is some more 1.5x anamorphics coming!

Resurrecting an old thread but I'm trying to figure out workflow and what resolution to shoot my gemini at with a 1.5x ana to get close to the 2.39 for delivery. Is general wisdom to shoot open gate and reframe in post?

Here's an old post walking thru my workflow with non-standard squeeze ratios, it all still applies to Gemini: http://reduser.net/forum/showthread...R-IS-Posible&p=1641356&viewfull=1#post1641356.

Also, if you're using an Iscorama 36 with your Gemini, I've found that a 40mm taking lens is about as wide as I can go without vignetting in full frame format. YMMV, depending on your adapter assembly.

Divide 2.39 by 1.5 and you get 1.593333..., so 1.59 : 1 is the aspect ratio of the sensor area that would get used to create a final 2.39 image if you crop and then unsqueeze by 1.5X. Ideally you'd find a format that used maximum sensor height and then crop the sides to get a 1.59 : 1 area. I'd probably select a sensor area that was slightly wider for safety, perhaps 1.78 : 1 is the closest option.

As already suggested, maybe use 1.3X in the camera for monitoring purposes.

Thanks David and Satsuki, very helpful!
