Videos created with Danim do not require a resolution higher than full HD (1920 x 1080 pixels).
Additionally, a frame rate higher than 30 frames per second is unnecessary.
However, some devices record in 4k (twice the resolution of full HD) with frame rates sometimes exceeding 60 frames per second.
If your videos are slow to load, this might be the reason. You should adjust your recording device to full HD (1920x1080) at 25 fps.
Since recording settings vary across devices, we can't provide exact instructions for every model, but the general steps are usually the same :
Go to settings on your camera or phone.
Find the format or resolution menu.
Select full hd (1920x1080) with a frame rate between 24 and 30 fps.
