Although i wouldn’t recommend this workflow for a hyper wall, you can “depending on your machine specs”.
After Effects maximum layer size buffer is 30000 x 30000, this sounds good but at 24000×13000 resolution and 25 fps & 8bpc workflow, each frame size is gonna be 1.2 GB. (each frame will be cached in the RAM during rendering).
by doing the math you need minimum of 32 GB to render one second of the video. but After that AE will soon crash and stop rendering because you don’t have enough memory buffer OR disk cache.
to solve this you can turn on the secret option in the preferences by holding shift + Edit > Preferences > General, the default value for “Purge every # frames during make movie” is zero, you need to change it according to your preferences and RAM. I would recommend a value between 5 – 10 in your case.
