How to Reduce Audio Hiss on the 5D Mk III when Recording Video 

Almost 4 years later and you have a big thank you from me. I'm totally new at using microphones and your initial white noise is the same or lower of what I am experiencing. Back to my microphone settings in the evening, I really have to check out if this is the solution. In any case, thank you for the proven point. It might not be my microphone after all, it might be just some settings to be adjusted.

just the video i was looking for! i use a 5d mark ii but the settings are identical thank you... 9 years later wow

This makes wireless Lav's waaay more tempting now. I usually put audio in a separate recorder, but this would take away the headache of having to sync audio with the added benefit of no audio hiss. Thank you so much. :)

Great video. Query: How do we manage if the mic that we have no external sensitivity adjustment?

Thank you so much. 2021 and this saved the day for me.

Holy crap. you just changed my videos forever. thanks so much!!!!!

Identification, explanation and demonstration! Going to apply this to the Tascam DR-60DMkii. Really appreciate your expertise and generosity. Thank you.

Best video on the internet. Period. 😊

Excellent tut, mate! I used the Sennheiser Ew100 for almost 20 years and the Canon 5DM2 since it first came out but never bother to use the cam as a video camera due to the poor AF, codec, no headphone jack, etc. etc. But now that Canon got the DP AF, wow! That's a game changer! So, I'm testing my old toys with your suggestion. It works out great! Thanks again for taking the time to make this tut.

THANK YOU. For a second I thought ALL recordings of videos had this white noise and post process was always a necessity, but I knew in the back of my mind the 5d Mk 3 didn't have a professional audio preamp built in. I thought buying an external shotgun microphone would solve my problems, but the white noise still persisted! Even with its' +10 db switch. THANK YOU AGAIN.

This is really helpful advice for adjusting my Canon T6i sound setting. Thank you.

Lekker, thanks for your help, just getting started with video. After years of stills still lots to learn! Great video.

Thanks ..This video is very useful

Amazing, thank you so much mate!

Solved a big audio problem for me too! Thanks a lot!

Great explanation! Thank you.

Brilliant! Thank you. Much appreciated.

Much much useful tips for getting clear Audio

Super helpful, we were having this issue after trying to skip using the zoom. Much appreciated!

You are an amazing person

It was the sensitivity of the ew100!!!! Went crazy today trying to figure this out. I had my ew100 sensitivity set to -33!

Best vid ever on how to stop hissing. I bought a yeti n thought it was being sensitive, as it's way more high maintenance than all my other mic's, but no, twas the camera settings. I thank you Sir. And obvs subbed immediately! :)

Thanks for this tip, it helped me improve my audio

Really thank you! Just helped a lot!

Thank you sir, very helpful.

Excellent sharing, thanks.

On the Receiver side, levels are called AF-OUT, which is adjustable from -30 db to +12db. Default is Zero db (For XLR input)

Which gives better audio Sennheiser G3 or Rode Videomic pro with boom kit ? which of these cancels background noise ? Thanks

thank you for sharing this tips

Thanks a lot for this great advice !!!

Thank you for the very helpful video

Hey, so the DSLR is the reason for the audio hiss? I've been having the same problem with audio hiss and I'm wondering if a simple audio recorder would help

Very helpful. Thank you. Will try this with my Sony wireless. Cheers! -C.M.

Just great

You are a life saver, thank you.

thank you for this video.... how can i physically fix both zoom and sennheiser receiver to the camera?

Great tutorial. Very informative. I admit I'm new to audio and Canon DSLRs. On the Levels displayed on the Canon LCD screen, I'm assuming those yellow dots on the right indicate peaking? I notice that when quite a few yellow dots were visible, you were saying that wasn't too much peaking. However, on someone else's tutorial video (which used a Panasonic mirrorless) it was recommended to have just a little bit of peaking on occasions. With the Panasonic camera, red bars indicate peaking. And they were adjusting it so that just one red bar would show up now and then on the Levels. I'm guessing that one red bar on the Panasonic would be equivalent to one yellow dot on the Canon. Just a little confused why a whole bunch of yellow dots on the Canon is an acceptable amount of peaking whereas on the Panasonic, just the occasional red bar is viewed as acceptable.

Hey buddy this was exactly the video I was looking for, background noise is a thing of the past!!! Thanks very much for the great step by step, all the best!

perfect! thanks!

thanks man

thank you! this really helps! :-)

Thanks. Clear and succinct. An alternative approach to this issue might be to install Magic Lantern then disable AGC.

thanks, Sir that's the insider tips, you save me

Thanks so much for making this video! It's solved my issue. The only thing I can contribute here would be to go into mode in order to get into the Manual sound settings.

is it possible doing the same procedure (setting manual sound level) in a EOS D1 Mark IV ?

Thank You!

Lifesaver!

Hi. So you have to buy a mic that allows you to increase sensitivty, right? For instances you cn not use a Rode mic, right? What is the cheapest mic that allows you to adjust it's sensitivity? Thanks

What was the sensitivity of the other receiver?

Thanks a lot...

Thanks gentleman

My receiver has no sensivity menu. How can I see it? I have ew100 g3 too and my camera is EOS 80D. I having instant peak and silent noise problem

great video! but what can I do when I don't use a wireless mic like that sennheiser, but a handheld microphone (reporter style) ? ..with a handheld micro I can't adjust the input signal.. Do you have an answer for me? thanks!

Great tutorial on how to adjust the audio settings but as an audio guy I'd leave head room and work with it in post. I'd never suggest allowing the levels to be close to zero.

The rec levels in my camera just peak the Left bar and the Right one doesn't work. Somebody knows the reason?

For some reason, I do not have those settings on my Mark3. It's a shame that there is nothing I can do!
