Hello - First time poster and first time DJI drone owner in the US on the FCC version.
I wanted to let you guys know that I reported this same issue to DJI on 11/22 and received a similar "weaksauce" response on 11/29 but with an important additional sentence: "We will release new firmware to fix this issue finally."
Here is the email response I received from DJI on 11/29:

Hello,
I hope this email finds you well.
This is to inform you that we have already received a resolution from our Engineers in regards to the issue you are having with your Mavic Mini. As per their response, because the default resolution of 2.7k is 2720 x 1536, but the video resolution of 2.7k is 2720 x 1530, so there will be a difference of 6 pixels at the bottom resulting to have a noticeable horizontal line of distortion at the bottom edge of the video.
To resolve the issue, please use a professional player (such as Potplayer) to play the video. If the player you used has hardware decoding and software decoding, if you choose hardware decoding, this phenomenon will occur, kindly use software decoding instead. This matter will be resolved when editing videos with editing software.
We will release new firmware to fix this issue finally.
I hope this information helps and your patience is highly appreciated.
Thank you for choosing DJI products and have a good day.
Best Regards,
Jess
