Background noise when recording in 4K - Xperia Z2 General

I've been watching lately some Z2 4k samples on youtube and I've discovered that in some videos there is a strange noise running in the background.Now, you won't notice the noise if the video was shot in a loud environment but if you listen carefully in these two videos, especially when there is complete stillness, you will be able to hear an unusual sound in the background.

Any opinions?

Extremely sound at video recording

I know it was discussed before but I just wanted to ask if there is a fix. I have turned all volume options to full and also used Audio Manager to set all of them to full. I can get good video recording quality but the sound is extremely low even if the external environment sound is too high.
I recorded my son at a concert where the volume was too high (of course) and I can hardly hear the music on the video. too bad.
I believe that the DHD records audio form the front of the device and so it misses some quality but still it's unacceptable to be that low.
Also the microphone records video audio at 32kbps bit rate, mono and 8KHz sampling rate, but the mic can record in better quality outside video recording with other software but for some reason it's like that while recording.
I think it could be to improve performance of video recording but who knows. I know it's really low and sub-standard but I don't think there's anything we can do......yet.
I think HTC follows their motto: "QUIETLY BRILLIANT"
Quiet everywhere.
That's the only thing that ****s me.

stupid question, is this a hardware fault or a software fault?

I would say software because the actual microphone can record in much better quality when you're just recording audio with some sort of a program.

[Q] Choppy sound in low noise environments

Good day forum,
I've noticed that the sound on video recordings will cut out completely or be very choppy or static when I record video (1080p30 or 60) in low noise conditions. Noisy areas tend to fair better. Do you think it's the overly aggresive noise cancellation? I've also noticed static when I have earphones in and touch the screen. Anyone else one or all of these problems?

Yes My LG G2 did the same thing. So I ended up getting rid of it. The audio on all videos with the LG G2 were horrible. Only a software update fix would help this. Not to mention the breathing auto focus problem.

Sound during video recording on the main back camera

Hey all!
Can you please compare the sound you actually pick up on the zuk to the any other phone you have when shooting a video?!
I mean the sound of the object you are shooting and not your own voice!
I tried video recording a song on the TV for my son!
On my zuk the sound looked very muffled and low compared the the sound i captured on the note 4 during video recording!
It's so low to the extent that I thought that the back mic (between camera and flash) is closed by something or not working at all!
Can anyone confirm? Did anyone notice it?

Yep, same here. Sound level during video recording is waaaay too low. Also tried sound recording app, same issue.
Same problem here. Thing I do when I made a video, I transcode it and boost the audio levels up. But yeah this should actually not have to do done. I hope this gets fixed in a new firmware update.

Weird sound while recording video

Hi! I've been using my S7E since March 2017. Recently, it has started doing noises while recording in 4k and other resolutions. It's like a fly noise, like if some mechanism into the camera was moving to focus. The thing is if I turn video stabilization ON the noise dissappears (I suspect it's the OIS, but on 4k and QHD video stabilization is not available, only in 1080p and lower). The phone also makes noise if I shake it (that doesn't bother me because apparently that's pretty common), even when the camera app is recording, it only stops if I activate video stabilization. It wouldn't be a trouble if it only was like this, because the noise isn't too loud. The trouble is that the phone mics capture that sound pretty loud and ruins audio in videos. I use zero camera mod, if you need it I can upload an audio clip with the sound.
Edit: I've just tried with my father's S7 standard, it does the click when shaked, but it does not make noise while recording
Edit2: I've just checked and it doesn't happen with QHD 30 fps, but it still happens with UHD, if I move the phone while recording on QHD there's no noise, but if I do it even just a bit in UHD the sound is there, is like if the Optical Image Stabilizer was trying to do it's job and it couldn't

Disappointing audio quality when filming videos at loud music concerts...

Hello all,
My previous phone was a Moto X Style (or Pure in the US) and the sound quality while filming videos at loud heavy metal/hard rock concerts was very good. My battery life having become abysmal, I decided to switch to the LG V20 last Fall, knowing I'll really miss the front-facing stereo speakers but thinking I'd improve the quality of my live music videos.
So far, 3 concerts with the V20 and struck out the 3 times. 1st 2 concerts, I tried to mess around with the manual video settings and the resulting videos had bad sound, clipping... Video itself was not too bad, but far from perfect. For the 3rd concert, I said, to hell with manual, I'll go fully automatic, as I did with my Moto X Style. Results for the audio were a bit better than with the manual settings, but still a far cry from what I got with my Moto X Style.
I read everywhere that the V20 was the phone to get if you wanted the best possible live music video recordings. And it's not happening. Is there something wrong with my phone? Anyone had manual settings they use at loud music shows they'd agree to share?
Thanks for any input.

You've got to open the Camera app, select Manual Video from the top (second screen), then ensure you've got your high fidelity audio settings correctly selected. You will likely need to reduce the 'Gain' setting to avoid clipping, as concerts are ridiculously loud. You'll find that the 'Concert' setting in manual video mode presets that for you.
If all else fails, HD Audio Recorder in the app drawer allows for high fidelity recording as well, albeit without the video.
Hope this helps, cheers!
Hi,
Thanks for the reply. But I don't see any Concert mode or preset in my manual video settings. Only in the HD Audio Recorder app. I'll try to match these settings into the HiFi manual video mode at my next concert next week. Any tip to get the best video quality at concerts, when not using the flash and having to deal with stage lights that are often no that dim?

My apologies, concert mode in HD audio recorder app is what I was referring to. Yes, you can copy those same settings into Manual Video mode though. That should help you out.
Here's a brief but very good beginners tutorial on video settings that you should learn to use with your manual mode in both video and photo applications. This V20 is fantastic at a multitude of different functions.
https://photographylife.com/iso-shutter-speed-and-aperture-for-beginners
Lastly, after studying these variables a bit and learning to play around with them in your own home, or outdoors during practice sessions, give it a shot at your concerts. You can always record during the opening performers prior to the main event. Run outside to the bathroom and see how well the video and audio recorded, then make adjustments from there.
**Note** I did say 'Bathroom' .. you don't want event staff to catch you making HD recordings of live performances lol! That'll get you in a bit of trouble.
ONE last mention; in manual video mode, you can toggle between UHD at 30fps (2160p) or FHD (1080p) at 60fps.
I would think due to low exposure and rapid light shows, you might want FHD60.
You've to record video using manual mode and then adjust your mic settings , becuase it has too many useful adjustments.
Thanks all. I'll try some more at my next concert (and messing around with the video settings at home next weekend).
I'm not the kind of guy filming all concert long, I think you lose the live experience doing this (and it sucks for people around). I just enjoy filming 60-90 second-clips of 3-4 songs to get souvenirs to enjoy later...

To keep it real imo, the v20 sucks when it comes down to just point and shoot. I get your point, I've been places where I just want to take a quick picture or video and it comes out horrible on my V20. When I switch to manual and adjust settings then the picture/video is very good. If you go to concerts a lot I would suggest different phone like pixel or take a few extra minutes in concert to get just the right manual settings.

Agreed, pixel 2 might be the king of all smart phone cameras to date. I purchased this V20 because it's identical to having a $350-400 external headphone amp.
On my reference level floor tower speakers, playing back lossless audio with high impedance mode... Oh boy it makes me tingle...
Well.... I'm starting to think my V20 has mic problems... Because I was at a concert on Monday. Recorded some live videos in manual mode, with the same settings as "Concert" of the Hi-Fi Recorder app. And the results are far to be stellar. Sound is not very good, still with some cracking. Image is fine. I even tried the Hi-Fi Recorder app (so no video) and the sound is not too good either... Really disappointed by this...
My Moto X Style was much better for this, without having to mess up with any settings...

If there's cracking, there's likely some kind of fault with the hardware.

Sounds like you have the gain set way too high.

Next time try these settings:
Увеличить
or these:
Увеличить
You look at the scale of the left and right channels next to the setting button. It should not be red, even in yellow is not desirable.
If the low frequencies are too strong, you can reduce the LCF to 75 Hz
If you want to hear some of my videos and say how the sound quality is.

Don't know if you'll see this? I have been live audience recording concerts for 23+ years. I just bought a v20 and had the same experience. Wasn't what I expected. Seeing this now. Didnt realize there were manual settings for video recording. The problem is the LMT. TURN IT TO "OFF". probably don't need LFC either unless there is too much bass in the room? Boomy sounding? Watch the gain settings too. 0db is probably fine depending on how loud the concert is. Turn it down if it looks like the Wave file is a solid block. The reason you don't want to use the LMT is because it suppresses the loud spikes in the music and it does it very slowly which makes the audio sound swishy. It ruined 3 clips I shot at a recent concert. I never use a limiter (LMT) when I record because of that. Good luck

Thanks for this. I think I already played with these settings with no success but will take a look again.
I think the micros of the phone might be defective...
Some i found from the web. Distance from the speakers makes a difference
