4k Proxy files - wrong aspect ratio

Hello,

I am about to edit some Red Raw 4k footage and want to create Proxy-Files. The "Create Proxy" Dialog offers me a Proxy Preset "Pro Res Proxy 1536x790" which is the Aspect-Ratio of my footage. The footage uses 2:1 Anamorph Pixels, the converted Proxy ends up with square pixels squeezed into the 1536x790 leaving wide black strips at the left and right. Can I somehow change that or create a custom preset?

Thanks,

rené

    I'm also having this problem - my RED anamorphic files are 5184x4320 (1.2 ratio) with a pixel ratio of 2.0 (effectively 2.40 ratio) but the Proxy presets only seem to allow for 1.0, resulting in the same pillarboxes when the proxy toggle is selected. The proxies were QT ProRess 422 Proxy, at 1536x790

    When I follow the Adobe instructions to create a new Ingest preset there is no option to specify the resolution or pixel ratio

    You can create a custom preset in AME. First you will want to Create Encoding Preset, setting your desired Format and select the Video tab to set the video parameters such as Width & Height, Frame Rate, Field Order, Aspect, etc. Just make sure that your frame size/PAR combination is evenly divisible with your R3D clip and that the Frame Rate, Field Order and Aspect all match the R3D clip.

    Now you want to Create Ingest Preset, click the checkbox for Transcode files to Destination and select the Encode Preset that you just created. Also set a Destination. Save the Ingest Preset and import it into Premiere.

    Hey Guys,

    for everyone who has the same problem as me.

    I found a good tutorial on youtube how to create custom ingest presets.

    If you change the aspect ratio in your preset on media encoder and use this for building a proxy in premiere, you should´nt have these problems anymore.

    You find the tutorial here :

    I made a few customs ingest presets that solves this problem for 4 common aspect ratios, you can download them here on my site!

    Hey Michael, 

    the download link is expired. Could you reupload the customs ingest presets for me? That would be awesome! 🙂

    Have you Modified the RED clips for proper display?  Before creating the Proxies?

    No. How?  (First time editing RED for me).

    The RED files show well though

    They don't come in squished?  Before making the proxies?
