"The USB-C output supports UVC streaming protocols," explains Ram Sarup, Canon Europe Product Marketing Specialist. "That allows you to not only use these cameras as a webcam, but for any form of livestreaming in Full HD at 30fps directly through a PC or Mac. That could be livestreaming a child's sporting event to family who live abroad on the LEGRIA HF G70, for example, or streaming a service at a place of worship, a lecture or a corporate event with the XA75/XA70 or XA65/XA60 – there are so many uses."
Deciding whether the Canon XA75/XA70 or the XA65/XA60 is the best camcorder for your livestreaming setup will come down to budget and whether you need the higher performance of the XA75/XA70 (which pairs its larger sensor with Dual Pixel CMOS AF) or the smaller form factor of the XA65/XA60. If you need an even more compact livestreaming camcorder, then the LEGRIA HF G70, which doesn't have the top handle or the two professional XLR inputs on the other models, is the perfect choice.
In addition to their livestreaming capabilities, these camcorders feature high-quality zoom lenses (15x for the XA75/XA70, 20x for the XA65/XA60 and LEGRIA HF G70) with 5-axis IS for sharp, stable images. They also include OSD (on-screen display) recording for embedding a time/date stamp into footage, and a useful infrared mode that's advantageous for low-light newsgathering, documentary filming and security work.
