Seam clip

Ledge clips are extremely precise clips where mario clips through a 90 degree angle where 2 adjacent walls meeet in a dive. It is nearly impossible to be consistent at a ledge clip but some ledge clips are more highly reported than others. For example, many people have clipped when attempting snow dram.

Ledge clips in captures

There have been some examples of people ledge clipping whilst in a capture. They are thought to be more precise than a usual ledge clip and are probably more useful. For example, here is a clip of a ledge clip in a fire bro https://clips.twitch.tv/PleasantIgnorantPeachHeyGuys and here is an example of a ledge clip in a podoboo https://twitter.com/warspyking/status/1168820156644020225.
