So I just picked up a Canon R6 and I am way out of my depth here lol. I tried taking some test videos in 4K and the camera kept giving me this error message saying the card was too slow or something? I think I just used an old card from my point and shoot. I am super nervous because I promised to film my sisters wedding next month in Seattle and I really dont want the camera to just stop recording while she is walking down the aisle.
I keep seeing these V numbers like V30 and V60 and honestly I have no idea what they mean or which one the R6 actually needs to not crash. I am looking for something that is:
- reliable above all else because I cant redo the wedding
- within a budget of like $150 for two cards if possible
- fast enough for high quality 4K video without those error popups
- easy to find at a Best Buy or on Amazon because I need them soon
Sorry if this is a totally basic question but there are so many brands like SanDisk and Lexar and ProGrade and I dont want to buy the wrong thing. Should I just get the most expensive one or is that overkill for a beginner? If anyone has the R6 and knows which specific cards actually work for the long 4K clips please let me know...

> I keep seeing these V numbers like V30 and V60 and honestly I have no idea what they mean or which one the R6 actually needs to not crash. Listen, dont panic. I have been through this exact thing with my R6 when I first got it. Basically, those V numbers are just the minimum speed the card can handle without dropping frames. For 4K on the R6, V30 is often too slow and causes that error you saw, especially if you shoot 60fps. You really want V60 cards to be safe for a wedding. I have used a ton of cards over the years and honestly, V90 is overkill for most people. I usually grab the Lexar Professional 1667x 128GB SDXC UHS-II V60 because they are super reliable and way cheaper than the high-end stuff. Another solid one is the ProGrade Digital SDXC UHS-II V60 Gold 128GB. You can definitely get two of those within your $150 budget. Just make sure you format them in the camera before you start shooting. Youll be fine!

^ This. Also, be super careful with the advertised speeds. I learned the hard way that the big number on the box is usually just the read speed. My first card for the R6 would record for ten seconds and then just quit. Now I always look for that V60 or V90 rating because it guarantees a minimum write speed... basically, dont trust the marketing fluff without checking the fine print first.
