Alexa Mini Anamorphic Rushes Avid Media Composer Workflow

Tue Feb 12, 2019 7:37 pm

Hi all

We have recently filmed some rushes with an Alexa Mini with the settings shown in the attached document.

Image

This has been edited in Avid and will be finished in Resolve.

We noticed that the Avid was not able to sort out the correct ratio for the anamorphic image - and we have tried a few options in FrameFlex, but none seem to get it quite right (despite following the settings from the above info).

Does someone have the correct settings for Avid MC 2018 or 2019 which will show the rushes correctly please?

Resolve handled it perfectly without any problem - so it isn't a huge issue - but it would be good to understand what settings are required in Avid.

We linked to the rushes and then transcoded at full resolution, but at neither stage could we get the correct display ratio.
The project was 1080p - which should be fine - and we were happy with a letterbox version as our final master. I assume the anamorphic element is the issue - although we did try several PARs.

Any suggestions on settings would be appreciated.

Many thanks
Jon.

Dear Jon,

I've asked our MC-Guru for a screenshot of the settings, here's the recommended setup:

Due to the adjusted padding when shooting on the Alexa mini LF in S35 mode anamorphic, avid displays a wrongly desqueezed image. I assume this is due to the fact that the software considers the pixel padding as part of the image.
Is there any workaround?

Best and thanks for your help, Moritz

Hi Jan

thank you for the fast response.
As a DP, I suddenly found myself in the middle of heated discussions about the proxies of one my my last projects since none of the frame leaders seemed to be working. I hope AVID finds a workaround soon. Luckily, Davinci Resolve etc. still works without a problem.

Best,
Moritz
