A scary video has emerged of two massive waves crashing onto a man trying to capture the rough sea in video.

The footage, shot in March last year in Port Albion, BC, Canada, captures the moment the filmer realises the waves are going to hit him and he needs to "get out of there immediately."

"Two rogue waves came heaving out of the ocean and far exceed the break wall I was expecting to capture," he wrote online.

"They rolled me over the rocks cutting through my pants and jacket leaving some light slashes on my calves and lower back."

After getting some fantastic photos of waves crashing I returned I a couple months later to get some up close video of the waves. I was watching this spot for about 5 minutes and waves were breaking just in front of it. So I set up back a little with a rock behind me and prepared to catch some great video. Two rogue waves came heaving out of the ocean and far exceed the break wall I was expecting to capture. They rolled me over the rocks cutting through my pants and jacket leaving some light slashes on my calves and lower back. After the first I was shocked and after the second realized I needed to get out of there immediately.
