If you already have a screen recording, add music in a video editor: import a track, place it on an audio layer, then position, trim and balance it against the picture and any other sound. That is different from choosing to record audio while you capture your screen, which is a setting for the recording itself.
The exact controls depend on your device and editor, but the editing decisions are much the same. This guide walks through a timeline workflow, with examples from iMovie, Clipchamp and Premiere on mobile, and explains what to check before you publish.
Adding music afterwards or capturing it live
First decide which job you are trying to do. If the screen recording is already saved, the usual route is post-production: open the recording in an editor, add a music track separately, and adjust the two layers on the timeline. You can do this without recording the screen again, provided the video file and music file are available to the editor.
Recording audio while capturing your screen is a different process. An audio choice in a screen recorder affects what sound, if any, is captured at that time. It does not add a separate music track to a recording you have already made. Android’s screen-recording guidance describes choosing whether to record audio before starting a capture; it does not establish that every phone or app can capture every kind of internal audio.
This distinction matters when you are following questions such as “How do I play music while recording video on iPhone?” or “Can I screen record music from the audio library and add it to my videos?” Those questions reveal two possible intentions, not a reliable answer about what a particular device will capture. If you need a soundtrack under an existing tutorial, edit it afterwards. If you need the sound of an app, check the recorder’s current settings and make a short test, because capture behaviour can vary.
There is also a practical reason to keep the music as a separate layer. You can move it, lower it, shorten it or remove it without changing the screen footage. If you record music into the original capture, it is mixed into that recording and may be harder to change independently later.
For a channel that turns completed videos into a continuous broadcast, audio preparation is still a separate step from assembling the stream. The guide to setting up a gaming replay stream with FFmpeg covers a different part of that workflow: preparing and running replay video, rather than adding music to an existing screen recording.
Choose an editor and a source for the track
Use an editor that can open your screen recording, import or select audio, and place it on a timeline. The most convenient choice is usually the one you already have on the device where the video lives. Moving a large recording between devices just to reach a familiar editor can add friction without improving the mix.
| Your starting point | A documented route | Check before you begin |
|---|---|---|
| iPhone or iPad, using iMovie | Add audio from the Music area or select a file through Files | The track must be available to the app; protected music-library items may not appear |
| Mac, using iMovie | Browse Music in the media browser or drag an audio file from Finder | Decide whether the sound belongs across the project or with a particular clip |
| Desktop, using Clipchamp | Import audio to My media or choose stock music in the Content library | Confirm the file format and that your account has access to the import source you plan to use |
| Phone, using Premiere mobile | Select an audio file from the phone’s storage | Find the file first and check that it is in a format the editor accepts |
The links in the table are examples, not a claim that one app is best for everyone. Apple documents audio-file and music-library workflows for iMovie on iPhone, iPad and Mac. Microsoft explains importing or choosing audio in Clipchamp. Adobe’s Premiere mobile guide describes bringing an audio file in from a phone. Menus and available features can change, so consult the current instructions for the version you are using.
You have two broad source choices: a file you bring to the editor, or a track offered inside its library. A local file is useful when you have a specific composition or recording in mind. An editor library can save you from finding and importing a file, but availability, account options and usage terms differ. A song appearing in a picker does not, by itself, establish permission to publish it in every context.
Before choosing, check four things: whether the track is available on this device, whether its format is supported, whether the editor can access its location, and whether its licence fits the intended publication. If you are making a tutorial for private review, that is a different publication context from putting a video on a public YouTube channel. Keep the distinction clear rather than assuming a track is cleared for all uses.
Import the track and place it on the timeline
Create or open the project that contains the screen recording, then import the music or select it from the editor’s library. In iMovie on iPhone or iPad, Apple describes using Add Media, then Audio, then My Music to browse downloaded music, or using Add Media and Files for an audio file. On a Mac, you can use the Music area in the media browser or drag a file from Finder. Clipchamp and Premiere mobile offer their own import routes, which may have different labels.
Once imported, look for a separate audio strip or layer beneath the video. Place it where you want the music to begin. If it should start with the first frame, align its beginning with the video’s beginning. If you want a short introduction before the music enters, move the audio later along the timeline. Use the playhead and timeline ruler to place the start, then preview from just before that point.
There are two common timeline relationships. Background music can run under a whole sequence or several clips. A sound tied to one moment—such as a short cue under a title card—should begin at that moment rather than simply at the start of the entire project. On Mac, Apple distinguishes placing background music in the music well from putting a song or effect under a particular clip. The names differ across editors, but the underlying choice is whether the sound should follow a section or belong to one specific visual moment.
Do not rely on the import step to put the music exactly where you want it. Some editors make an initial placement for you. Apple says that an iMovie song added on iPhone or iPad is placed at the beginning and fitted to the project length; a shorter file may need the playhead positioned first. Check the actual timeline after import rather than assuming the editor has interpreted your intention.
If you are preparing a sequence of clips, settle their order before fine-tuning music. Changing the picture edit afterwards can leave a cue attached to the wrong moment or create a gap. For a long-form YouTube project, the same planning applies when you assemble a continuous sequence: the article on creating a looping podcast live stream addresses programme structure, while this timeline step is about synchronising audio and video in the source edit.
Position music to fit the action
Play the video and watch the timeline as you listen. Decide what the music is doing: providing a quiet bed under a tutorial, marking a transition, or filling an opening or closing card. That purpose determines its start and end points. A tutorial with spoken instructions may need the music to enter after the opening explanation; a silent screen capture may have room for music throughout.
For a single cue, move its clip until its first meaningful sound lands where intended. The file may contain silence at the front, so its visible left edge is not always the point you want the audience to hear. Listen from slightly before the cue and adjust by dragging or splitting as your editor permits. If you move the video clips later, revisit the cue’s position as well.
For background music, think in phrases rather than only in total duration. A change in the screen action, a title card or a pause in narration can be a natural point to bring music in or out. You do not need to cut on every visual change. A continuous bed can make a long sequence feel coherent, but too many abrupt edits can make a simple tutorial feel unsettled.
When the project has multiple clips, avoid assuming that a soundtrack should attach to the first clip. If the editor offers a project-wide music area, it may be suitable for a background bed. If it puts audio under a selected clip, confirm whether the sound will move with that clip when you rearrange the edit. Scrub across the joins and listen for unintended gaps or repeated starts.
A screen recording can also be part of a longer live-channel programme. In that case, decide whether the music belongs in this edited video or in the wider programme mix; these are different stages. If a source video ends and the channel continues with another item, plan the transition rather than letting the audio stop unexpectedly. A separate guide to adding a countdown between podcast episodes covers one kind of transition in a live sequence, not a substitute for editing the soundtrack here.
Trim the track to fit the recording
A music file is rarely the exact length you need. Select its audio clip and shorten the end to match the video or the section where the cue belongs. Most timeline editors let you drag a clip edge, split it at the playhead, or use a trim command. Clipchamp documents moving, splitting and trimming timeline audio, while Adobe describes trimming an imported track in Premiere mobile.
If the track is longer than the picture, trim the tail rather than allowing music to continue over an unintended blank screen. If it is shorter, decide whether it should end at that point or whether you have permission to repeat or extend it. Repeating a track can create an obvious seam, especially if the ending and opening do not flow together. Listen across the join before keeping a loop.
For a short cue, place the playhead at the intended start before adding it if your editor uses the playhead to determine placement. Apple notes this step for a file shorter than a minute in iMovie on iPhone or iPad. That is an editor-specific instruction, not a universal duration rule. In any application, check the clip’s actual position and length after insertion.
An abrupt cut may be acceptable for a brief sound effect, but music usually benefits from a deliberate ending. If the editor offers a fade, use it to soften the exit and listen to the final seconds. Keep the fade within the available audio; extending it past the trimmed clip will not create sound where no track remains. Similarly, avoid trimming so tightly that the last audible note is cut off unless that is the effect you want.
After trimming, play the last part of the video and a little before it. This catches a common mistake: the picture reaches its end while the music continues, or the music stops while the screen is still showing a closing instruction. If you are making a sequence that will later be part of a longer channel loop, check that the ending makes sense both as a standalone recording and at its intended transition point.
Balance music against narration and other sound
If the screen recording includes narration, clicks, alerts or app audio, treat those as meaningful parts of the mix. Start playback at a section with speech and lower the music until you can follow every instruction without straining. Then check a section without speech. The music should remain audible enough to serve its purpose, but it should not take over the video.
There is no universal numeric volume target for this workflow. Source recordings differ, as do editors, playback devices and listening environments. Adjust the music by ear, using the editor’s volume control, and listen on the device or headphones your audience is likely to use. Do not treat a single slider position or ratio as authoritative across projects.
If the original recording has useful sound, decide whether to keep it. A software tutorial may benefit from a click or notification that explains what happened. A distracting fan hum or accidental conversation may be better reduced or muted if the editor allows it. Changing the original audio is separate from adding the new music track; check that you have selected the right layer before adjusting a control.
Listen at ordinary playback level, not only while staring at the waveform. A waveform can show that sound exists, but it does not tell you whether speech is intelligible or music feels intrusive. Check the loudest spoken section, a quiet section, and the transition into and out of the soundtrack. If the music masks an important word or action, lower it or change where it plays rather than expecting viewers to work around it.
For a screen recording that contains no narration, the balance still matters. A track that is too prominent can make a simple demonstration tiring; a track that is barely audible may add nothing. Preview on more than one playback device if practical, and make small changes until the music supports the visual task rather than competing with it.
Check rights, then export and review
Before exporting, check the source and terms for the music you chose. Music in a personal library is not automatically cleared for a published video. Apple notes that protected music-library files may not appear in iMovie, and that using a song purchased from the iTunes Store in a project requires the user to hold the copyright or have express permission from the copyright holder. Check the actual licence for the track and the rules of the platform where you plan to publish; do not infer universal permission from access in an app.
YouTube’s guidance for enhancing Shorts warns that copyright-protected content used in Shorts created outside YouTube’s creation tools may receive a Content ID claim or be removed following a copyright removal request. That is guidance about the stated Shorts context, not a blanket statement about every video or every music source. For your own upload, consult current YouTube Help and the music licence that applies to your use.
Before export, watch the whole recording or at least review every edit point and the beginning and end. Confirm that the picture is intact, the music starts where expected, the narration remains clear, and no soundtrack hangs over a blank tail. Use an export setting that fits the destination and preserves the dimensions and quality you need; exact controls differ by editor, so use its current export options rather than copying a setting from another device.
After export, play the exported file itself. Do not rely only on the editor preview: an export can reveal a clipped ending, missing audio or an unintended gap. If the file is going to be part of a 24/7 YouTube channel, check the finished asset before it is added to a larger sequence. You can also plan the upload and hand-off separately; the guide on how long video uploads can take for a YouTube 24/7 stream covers that next operational question.
If importing fails, check that the file is stored somewhere the editor can access and that its format is supported. Apple lists M4A, MP4, MP3, WAV and AIFF as examples for iMovie file audio; Microsoft advises checking supported formats if a Clipchamp audio file will not import. Those are examples tied to the named editors, not a guarantee that every app accepts those formats. If a track is missing from a music picker, confirm that it is downloaded locally and not a protected item unavailable to that editor.
Once the recording, music and rights checks are settled, choose how you want to manage the final video and its ongoing broadcast separately.

FAQ
Can I add music to a screen recording after I have made it?
Yes. Open the existing video in an editor, import a local track or select an available library track, and place it on a separate audio layer. Then position and trim it, adjust its volume, and preview the result. This post-recording edit does not capture music during the original screen recording.
Is adding music afterwards the same as recording audio while I capture my screen?
No. A screen recorder’s audio choice applies to a new capture, while adding a music track is an editing step on an existing recording. Device and app behaviour varies, so check the recorder’s current guidance and make a test if you need to capture app audio.
Why can’t I find or import my music file?
Check whether it is downloaded or stored in a location the editor can access, and confirm that the editor supports its format. A protected track may not appear in a music picker, and import sources can differ by app or account. Try a supported local file if you have the rights to use it.
Does a track in my music library mean I can publish it on YouTube?
No. Availability in a library does not establish that a track is cleared for your video or every platform. Check the music’s licence and the current rules for the place where you intend to publish; YouTube may apply its copyright policies to protected content.
