No. The biggest problem with being so close to the speakers (you originally
said "about 3-4 meters from loud powerful cabinets") is that the SPL (sound
pressure level) will be so high that it will overload almost any mic that
you can afford - and a lot that you can't afford as well.
Ideally you have a separate sound mix done for video use only. This
involves a lot more pre-planning on your part though as this MUST be
discussed with all parties long before the actual event. On most concerts
I've done, I'm running a camera only. Audio is handled by someone else.
All on-stage audio (performers, instruments, etc.) are run through audio
splitters so that everyone (band P.A. & audio-for-video) can do their own
independent mix.
One final thought. Did your ears ring the next day? If the answer is yes,
then you've done permanent damge to your hearing. It may not become
apparent for 10-20 years but you have done damage. Current OSHA regulations
prohibit exposure of any duration to sound-pressure levels above 115 dBA
unless hearing protection is used. It's not uncommon for concerts to exceed
this level. This is why a lot of rock & roll musicians are now hearing
impaired :-(
