>>4180417The 30 min limit is being phased out, as the EU has updated its bullshit policy (so now we just got to deal with overheating). If you're dealing with a Canon EOS camera, there's Magic Lantern. There are also a few Nikon hacks which can disable the limit. That's about it. For anything else, you'll need an external recorder. You can DIY one of a Raspberry Pi or similar system and a capture card, but the best solution is to just buy an old, used Atomos or last gen Blackmagic Video Assist. You can find them for like $100-200.
