Stretching RAW Video Canon 1100D Problem

[Mike2000]

Hello,

I installed the last firmaware available for my canon 1100d, I recorded a couple of RAW videos in 14bit, 2:35:1 ratio and 1280x326 resolution. I searched online for an answer but I didn't get the "stretch 1.67x to get the 1280x544 resolution in post" point, I tried to stretch vertically the video and I exported it as 1280x544 but the video looks stretched, so probably I'm doing something wrong, could someone please help me?

Thank you for your time,

Michele
