I just bought a Nikon D780 to film my sisters wedding in June but the sound is really scratchy right now. I have about $150 to spend and zero clue what I am doing with gear so sorry if this is a dumb question... what mic is actually easy to use for this?
I'm really happy with the <a href=" https://www.bhphotovideo.com/c/search?Ntt= Sennheiser+MKE+400+On-Camera+Shotgun+Microphone&BI=8941&KBID=10361&SID=12345&DFF=d50" target="_blank" rel="nofollow sponsored">Sennheiser MKE 400 On-Camera Shotgun Microphone right now. Its 20Hz-20kHz range and 3-step sensitivity switch are great specs for the price. They work well. I've also been satisfied with the <a href=" https://www.bhphotovideo.com/c/search?Ntt= Audio-Technica+AT8024+Stereo%2FMono+Microphone&BI=8941&KBID=10361&SID=12345&DFF=d50" target="_blank" rel="nofollow sponsored">Audio-Technica AT8024 Stereo/Mono Microphone for weddings because you can toggle patterns for the vows. Both fit your $150 budget and solve those scratchy internal preamp issues. Honestly, you cant go wrong with either choice!
Honestly, for a wedding, simplicity is your best friend because things move fast. The scratchy sound youre getting is likely just the internal camera preamps struggling. With $150, you have some solid options that are basically plug and play.
TL;DR: Manual gain is your friend. The D780 preamps arent bad, but auto-gain will ruin your audio by hunting for sound. Set it manually to around 4 or 5 and use a powered mic. Avoid cheap, unshielded cables tho... weddings are full of RF interference from phones thatll cause clicking in your recordings. A powered lavalier is a solid alternative if you can hide it on the groom.
