Audio disappears from iOS 11 Screen Recordings when the video is uploaded

Haha that is the truth! Kids truly amaze me with all they know about technology and I love it! I actually do have he mic option on and when I go to my camera roll and watch the screen recording it’s there with sound but the second I try to put it on instastory the sound goes away :( would you happen to know anything else I can try? Thank you so much for your reply !

I confirm the same behaviour with two audio tracks on my iPad.

When I open the recorded video using VLC media player I noticed that file has two audio tracks, track #1 is just silence (and it is taken by default by most players, that is why you hear nothing), track #2 contains recorded audio.

I don't know why Apple decided to implement it that way, or maybe it is a bug. It is annoying and I hope they will put sound in track #1 by default. Is there some way we could report this?

Apple:

I‘m a teacher too with students that are dealing with the same issue. Please Fix! It’s not a good solution for kids learning your product to have to use multiple go arounds.

Hoping for a speedy fix on this glitch.

This is fixed - I use it all the time and it works great - the iOS team took care of this in a release a few weeks ago. I think they combined the 2 audio tracks into one. Make sure your students turn their microphone on prior to recording.

How long are your recordings? Ours are over 1 minute. My iOS is updated as well as my iMovie app and I’m still experiencing the issue. I want to clarify, are you putting your screen recordings in iMovie? I can create a screen recording with sound, but the issue is once the recordings are added to iMovie the sound doesn’t work.

If you have any suggestions as to what I’m doing wrong I’d greatly appreciate it.

Hi,

I was still having this same issue a couple of months ago and now I no longer have that issue when loading video onto Facebook, Youtube, and Instagram. The issue was fixed with the latest Iphone IOS update. So just make sure you phone is the most up to date and you should have no issues.

I fixed it by opening the file in Quicktime 7, show Movie Properties and deleting the empty track, then save.
Now Youtube only has one track to work with. To figure out which track to keep, extract the audio tracks and listen.

I'm still having an issue, though not when uploading video directly to social media, but when I attempt to upload the video to YouTube. The video has no audio after airdropping the video (with sound) to my MacBook pro. I'll try uploading the video to YouTube directly from my phone but right when I thought everything was working fine, the YT upload has no audio...

I have a teacher that is still having this issue uploading to YouTube. I was able to recreate it as well.

What I found is that if we transfer the recording to a laptop (we used AirDrop) and then uploaded it to YouTube, the audio would not play when viewing on YouTube. When we upload the recording directly from an iPad to YouTube, the audio would play when viewing YouTube.

So it looks like uploading the iOS recording via the iPad, directly to YouTube does work for us. We are both running iOS 11.2.6.

The additional problem my teacher had is that her recordings are a little over 20 minutes. The YouTube app on the iPad limits you to 15 minutes of video or 128GB. However, uploading via a web browser does not have this limitation. So, we went to YouTube in the mobile safari app on the iPad and uploaded the video that way.

We did have to have our iPads request the YouTube desktop site before we could get full functionality.

Sound and video played as expected via YouTube after that.

I did read there may be a way to increase your 15 minute upload limit. I will try it an report back.

I have some additional information regarding uploading from an iPad.

When we upload the screen recording using the YouTube app, there is no audio.

When we upload the video from the camera roll (using the share arrow) and choose YouTube, the audio works.

We did enable our accounts for Longer Videos (allowing more than 15 min), but the video would still not upload. Using the YouTube app, the video would give a generic, "Error processing file" message. I suspect it has to do with file size. When uploading the long video from the camera roll to YouTube, it gives us a message that says the video cannot be longer than 15 minutes (even though we have Longer Videos enabled).

I used Splice and it worked for me. Edit with Splice instead of iMovie.

I tried this as well. But video acts funny in Premiere Pro. Doesn't work right like when playing in my iPhone.

Maybe try downloading iOS 11.0.1
