External mic = noise?

I have a rode videomicro that I use with my gopro, but I wanted to try it with my canon 5d mark IV. The audio sounds a bit better, but there is horrible noise/interference added. No problems like this with the gopro.

Anyone else have this situation? Anything I can do? I have heard it's better to use a powered mic (which I don't have) but surely an unpowered mic would still be acceptable, especially since it even works with a little gopro?

Does it sound like wind, or mechanical "noise"?

As a diagnostic matter, [1] did you test the audio with this mic and the 5d4 on one occasion or more than one occasion (getting at whether or not there was interference), [2] did you later test the same mic with the gopro again (to rule out a failure of the mic or cable), and [3] have you ever tried a different external mic with the 5d4 (in order to rule out a failure of the 5d4's mic port whether it be a mechanical failure or some type of obstruction)?

I don't want to hijack, but don't want to start another mic thread if I can budge in here a bit.

I was interested in this mic since when shooting videos with my 5D4, my lenses are LOUD with AI Servo on. It's constantly focusing, so it's pretty much unusable.

Will this mic get around the focusing noise? I will likely be using a Canon 35mm f2.0 IS (IS off) or the 24-70 f2.8 II. Or should I get something else?

No mic will get around noisy lenses - it's their job to pick up sound! Get the mic off camera - use an extension and/or bracket, or better still use an external recorder and sync in post.

As for the noisy mic on a 5D4, look no further than the crappy preamp inside Canon DSLRs. My 5D2 audio is hideous in comparison even to an iPhone or GoPro. That little Rode isn't the quietest mic out there, but it always sounds awful in my 5D2. Turn down your in-camera record level and raise in post if needed - but you're honestly better off just recording your audio externally and syncing.

Here's a quick comparison between the Rode Videomicro on a Canon and on a GH4. Quite a substantial difference. Similar story plugged into a DJI Osmo or GoPro

I found that the powered Rhode video pro works better on my Canon vs non-powered mics (which does exhibit noise at even reduced recorded audio levels). Rhode claims an extra 20db improvement with the amplification/filter of the 9 volt powered version. The length of the microphone might help reduce some lens noise, but it won't eliminate it.

I just picked this up for $43: https://www.amazon.com​/gp/product/B06XB63MG5​/

Just a cheapo solution to get around the lens noise. A HUGE improvement but not perfect. It's good enough for me. I just wanted anything but the camera mic for recording some youtube videos.

Having levels set to 75% is way too high.

I've seen it recommended to set manual audio levels at 1 or 2 clicks above minimum and then sort it out in post - will give a much nicer result as it minimises the impact of the crappy Canon in-built pre-amp.

Of course it is. I didn't set the levels to be noise free. I set them to be as close as I could get them to compare the noise floor of both cameras.

You missed the point of the clip somewhat - WHATEVER you do with the settings on the Canon, its audio is never going to be as clean as the Panny - or even a GoPro or DJI Osmo. Record audio off camera!

Is 75% something on the camera itself (never used camera controls - no headphone jack)?

Also, I'll vouch for the external audio recorder being the right way to go 100% of the time unless space won't allow for one in the bag. I've only used Marantz recorders, but there are comparisons up on youtube for DSLR vs external sound recorders, it really is night and day. Just to give an idea, I just finished a recording session on a PMD661, and it will clean up nicely enough to be considered broadcast quality.
