Is the canon eos 5ds good for video?

The site doesn't have video specs for the Canon EOS 5DS, so I can't tell you how well it shoots video. Its page describes a 50.6-megapixel DSLR built for landscape and studio stills, with no stabilisation in the body, so you'd need stabilised lenses for slow shutter speeds.

Judged by the checklist in Video, the things that matter are a screen that flips to the front, a wide lens, a microphone input, and light weight. The 5DS page doesn't list a flip screen or a microphone input, and a full-frame DSLR isn't the lightest rig, so check those on the manufacturer's spec sheet before you buy.

If video is your main job, the vlogging section points to small APS-C or 1-inch cameras, and the audio section covers sound from the start.
