What should you do if your screen recording has no sound?

Solve Mac or Windows Screen Recording Has No Sound

Few words can’t make it clear why computer screencasts come out with no sound, because the possible reasons are diversified. You may forget to turn on or increase the volume of speaker or microphone. The audio driver may be out of date. There is some software conflict that prevents your current recording tool to access the audio source. Or the tool itself has no right to rip the audio from audio card. QuickTime screen recording has no sound is a typical example.

In view of this, you’d better firstly check your audio devices and system settings to ensure your recording app are allowed to use (microphone) sound. Then close all of the other background useless applications, and update or reinstall the audio driver. If possible, equipping your robot with a more quality screen and audio recorder like RecMaster to be responsible for the screen capture is quite recommended.

In general, a screen recording expert makes every screencasting requirement a handy. So does RecMaster, who are able to grab and encoding all the screen activities with audio into H264 MP4 HD, or a pure audio file. Multiple monitors are also supported for gaming or working related capture. Let’s see how it works on Windows or macOS. Now you can get it downloaded and installed on your desktop or laptop.

Mac Download Link: https://apps.apple.com/us/app/id1466014165

Step 1 – Open RecMaster and prepare the content you may need to record, e.g. Powerpoint presentation, online streaming, PC game, conversation application and so on.

Step 2 – Choose a mode and do settings.

RecMaster gives multiple options for users to choose. Specifically, from game mode (Mac version will add this mode soon), full screen, custom area, webcam to audio only, you should pick the one according to your actual capture source and size.

Settings you are empowered to adjust are various, including file format, video quality, frame rate, webcam overlay, system sound and microphone source and volume, mouse cursor effect, watermark, hotkeys and output file destination.

Windows version has an extra “task schedule” feature to create any on-time capture automatically.You can check out jow to schedule a recording on computer.

Step 3 – Record screen with sound as you prefer.

Based on the settings, RecMaster will initiate a recording in your own way once you hit the REC button. During the recording time, annotating is available. And after the recording, software offers easy editor and YouTube-sharing entrance.

Solve Screen Recording on iOS  Has No Sound

Many iPhoners come up with such silent recording matter when they use internal recorder to capture streaming from YouTube, iTunes, Instagram, facecam, Facebook, WhatsAppp, safari or other places.

● To walk this annoying error through, you should firstly ensure you’ve done the right operateion. When you add and access the Screen Recording in Control Center, do turn on the Microphone Audio button to allow recording with both micphone voice and system/app sound. Turning this option off means capturing iPhone’s internal sound only. If you close Microphone Audio and ringer together, you will get a muted recording in the end.

● Still voiceless? Then you can try resetting all the settings of your phone to original or restoring your gadget with iTunes backup. If your phone doesn’t running the latest iOS (13), maybe it’s time to update your iOS.

● There are also cases that it’s the DRM copy protection that restrains your audio capture. At this time, you will have no way to record but simply enjoying the video or music with your subscription.

● If your target is not copy protected content and you still fail to record the sound after completing the methods mentioned above, there’s another simple workaround – mirror your iPhone screen to PC and then conduct the capture. Below are the steps.

Step 1 – Use adaptuer plus HDMI combination, Wifi or USB + mirror software to move your iOS screen to compture. The workflow of the former one is to plug Apple’s Digital AV adapter into the charging port of iPhone, and then use HDMI to connect it with PC monitor. Note that VGA adatpter is not recommended for the connection because it’s unable to carry audio signals. To wirelessly mirror iPhone to PC, you need a dedicated helper like Let’sView.

Step 2 – Open up the mirrored monitor and get a screen recorder ready on the computer. If the mirror software has screen recording feature, then take advantage of it. If not, use computer’s internal screen recording tool, say Game bar (for Windows 10 only) and QuickTime. Since they are not so flexible as standalone screen recorder, you can switch to RecMaster and take advantage of this iPhone screen recorder for computer here. 

Step 3 – Start up your iPhone activity and enable the screen recorder to work in your way.

Step 4 – Stop and edit if necessary.

How to Record Zoom Meetings with RecMaster

Great moments should be recorded for further usage or taste. Then how to record Zoom meeting or call on computer? Briefly you have two ways to go: use the built-in recording feature or leverage a third-party Zoom recorder. You may ask which is more suitable for you, well, it really depends. Please go through the following content before you make the final wise decision.

 Limitations of Zoom App Recording

Everything on the planet has its pros and cons, therefore when you take Zoom recording with its bundled feature, there are something you’d better make clear in advance.

1. Since any meeting includes two characters, host and attendee, the host is surely born with more powers to decide whether to allow the meeting recording, whether to give each single attendee the privilege to record, and the capability to auto-record. In other words, the participants may be limited to create Zoom recording.
2. For local recording, only PC users could enjoy the benefit, which means if you are using Zoom on mobile, you are forced to turn to cloud recording or any standalone recording app. When conducting local recording on desktop, you’d better keep the file location on local drive but not to a cloud syncing folder from external places, because some converting or saving error may appear during cloud syncing.
3. For paid users, Zoom enables cloud recording automatically, so take a note on the available cloud storage. If the recorded file exceeds the maximum size, only after you pay for the piece of video or audio can you obtain and watch it.
4. Another risk of Zoom recording is that if the meeting is suddenly ended for internet or whatever reason, the recording on the going will be corrupted and unable to recovery.

Zoom App Recording vs Third-Party Recording, What’ s the Difference?

They two recording methods both have their own strengths and weaknesses. Below are some typical differences.It’s undisputable that Zoom is an excellent teleconferencing service which is stocked with handy and optional recording functionality. But as the information that’s moved from official sites hints, recording or file converting failure is still possible for local recording. To guarantee a more stable recording with no fall, you are suggested to invest an advanced subscriber with sufficient cloud space or employ a reliable Zoom screen recorder.

Recording Permission	The hosts are free to record while the attendees may be prohibited to record.	Anyone joining the meeting could take a screencast.
Recording Modes	Free users can only enjoy local recording while licensed people are offered both local and cloud recording modes.	Only supports local recording
Recording Length	No limit for local recording while it’s restricted by the cloud storage.	No time limit.

Recording Stability	Any unexpected shutting down of meeting or file conversion will result in a corrupted or non-recoverable recording.	What’s going on in the Zoom app will not affect the software recording.
Others	Able to record audio files for any participants who speaks separately and has the recording transcribed; Public behavior that everyone knows you’re recording;	Usually has features of annotating, editing, schedule recording and one-click sharing; Recording secretly.

Possible Fixes on OBS Studio Black Screen Error

If you are encountering a black screen error when capturing screen on Windows PC, try the following possible solutions to work this problem out immediately.

Fix 1 – Restart OBS Studio and Computer
As a general solution, restarting software or rebooting the machine can resolve many unusual behaviors. So don’t take it as a flippant one. Just do it with patient. Also, you can check and update OBS if there’s new software release. Totally depends on yourself.
For Windows user, if the problem still exists after that, do check whether the OBS bit version you installed is suitable for your Windows system. Don’t be silly to set up a 32-bit version OBS on your 64-bit PC or vice versa.

Fix 2 – Close Other Software, Especially the Screen Capture Software
In some few situations, it’s the application running in the background that affects OBS’s performance and this is the software conflict. Close the irrelevant programs completely with task bar, especially the one regarding screen recording or broadcasting.

Some OBS users still reported that the Game Mode, designed especially for optimized gaming or Game Bar capture performance on Windows 10, may cause black issue, so check and disable Game Mode if you have enabled it under Settings -> Gaming -> Game Mode.

Another Game-Mode-alike way that many computer geeks love to take advantage of for gaming speed-up is overlocking. Either CPU or GPU can be overlocked to get an increased clock rate of component if it doesn’t ship with locked multipliers. If you’ve allowed it on your computer, disable the overlocking to see if it works.

Fix 3 – Run OBS as Administrator or In Compatibility Mode

In case OBS Studio doesn’t have the right to do screen capture, run it as Administrator. If you’ve installed and placed it on the C:// drive, you’d better change its driver permission by right clicking and accessing Properties -> Security -> Edit, and enable Authenticated Users to have Full Control.

This operation grants users to have totally permission to utilize OBS. And as to black screen matter brought by software compatibility matter, it will disappear while you still right clicking OBS shortcut and click Properties -> Compatibility, and tick “Run this program in compatibility mode for:” other Windows version number say 8, 7 and such.
​
Fix 4 – Switch Capture Mode or  Method
If you can’t see the capture image in certain capture mode like Window or Game capture, alter the resource option to see if it works. And for Game Capture, make sure you are running game firstly and then add Game Capture in OBS Studio. Also, running the game at full screen, but not windowed or borderless if the Mode is “Capture any fullscreen application” on Game Capture Properties. Another option on this Properties panel – “SLI/Crossfire Capture Mode” could also help to maintain a regular capture basically when your computer has two (NVIDIA/AMD) graphic cards built in. (More fixes on OBS black screen on multi-GPU computer will be detailed later.)
For Window Capture, there are three capture method options on its properties now: Automatic, BitB1t (Windows 7 and up), and Windows Graphics Capture (Windows 10 1903 and up). You should pick the one according to your system condition.

Fix 5 – Change Graphics Settings
Following solution 4 which concludes some GPU-related operation on software, this one is mainly for settings on system. If your computer is running two GPUs or you’re doing screencasts on laptop, black screen is a usual case. That’s because due to certain system update or the system settings by nature, OBS Studio and the on-screen content you plan to grab (e.g video game and display) are running at different graphic card. Consequently, OBS Studio is unable to initiate the capture. At this time, you can alter the Graphics specifications to fix this issue. The steps are super easy:

● For Windows 10 1909 or later: Go to system Settings -> System -> Display, and click to open “Graphics settings”, where you should select “Classic app”, browse to where you have installed OBS (e.g D:\Program Files\obs-studio\bin\64bit\obs64.exe) and add the app into the list. After that, click “Options” of OBS Studio and alter the graphics preference of OBS Studio app form System default to “Power saving” or “High performance” manually. Power saving is recommended for display capture while High performance is for game capture or using NVENC encoder.

● For older Windows computer with NVIDIA card: Desktop or laptop, you need to enter into the Nvidia Control Panel and then navigate to Manage 3D settings -> Program Settings to add and select OBS Studio to customize. What comes next is to select “Integrated Graphics” for common desktop display capture or “High-performance NVIDIA processor” for game capture.

● For browser capture with black display: Browser rendering often takes much sources, therefore in order to improve the efficiency, browsers like Chrome and Firefox supports and will use hardware acceleration by default. Give it a try to disable browser’s hardware acceleration to settle the OBS black screen on Browser capture.
Yep, in this way, you can keep the recording content and OBS Studio running on the same GPU so that there’ll be no black screen error any more. Actually for recording gameplay on high-end computers, there are also many decent game recording software you can rely on.

Fix 6 - Reinstall OBS Studio
Reinstalling can also be done at the very beginning in case there are some unknown bugs of the existing setup.

Fix 7 – Try Best OBS Studio Alternative
If the display error always exist even after you've finished all of the possible troubleshooting methods, you can only turn to another screencast software. Below are some recommendations:
Open source software: CamStudio,  ShareX,  Ultra Screen Recorder, Virtualdub etc.
Free software: Ezvid, Fraps
Shareware: RecMaster, Bandicam, Movavi Screen Recorder
