A vMix List can advance through media and loop it, but that does not by itself restart vMix or reconnect your YouTube broadcast after Windows reboots. Configure the playlist and YouTube encoder settings separately, then test the complete restart on the computer you intend to use.
There is no universal restart recipe established by the documentation reviewed here. A successful Windows login is only the first check: you also need to confirm the saved production, playlist playback, encoder connection, live status and public picture and sound.
What playlist looping does and does not do
A vMix List input is for playing a sequence of video or audio files. With Auto Next enabled, playback can advance to the next item; with Loop enabled, it can return to the beginning of the list when it reaches the end. The List guide also describes support for M3U playlists. Check the actual input in your production rather than assuming it has the settings you expect. (vMix List input guide)
These controls govern media playback inside vMix. They do not schedule playback for a particular time of day, relaunch the application after a reboot, or ensure that the YouTube stream is live. vMix says it does not support time-of-day scheduling, while describing List and Playlist features for basic or continuous playback. (vMix scheduling guidance)
Keep these as separate operational states. Your List may be looping while the production is not sending a stream. The production may be open while the YouTube encoder is disconnected. The encoder may be sending data while a viewer cannot yet see the intended programme. This distinction matters most after a reboot, when several parts of the workflow may need attention.
If your main requirement is simply to keep a set of files playing, start by testing the List itself. If the requirement is to return to broadcast after Windows updates, test application launch, production restoration and YouTube reconnection as additional steps. For a useful comparison of media-looping approaches in another production tool, see OBS Media Source versus VLC Video Source.
Configure the vMix List input to advance and loop
Create a List input from the intended media files or an M3U playlist. Confirm that the files are available at the paths used by the production and that the order is right. A playlist that depends on a removable drive, a mapped network location or a user-specific folder may behave differently after a reboot or login, so include those dependencies in your test.
Check Auto Next and Loop on the List input. The vMix guide says Auto Next is enabled by default, but the default is not a substitute for checking the saved production. Start playback and watch it move from one item to the next. If you can, test through the final item and confirm that the list returns to the beginning without an unintended pause or change of input.
Also listen and watch during the transition. A list can advance correctly while one file has no audio, an unexpected aspect ratio or an encoding issue. Check that the chosen input is actually part of the output you intend to send to YouTube. In a production with overlays, titles or other inputs, confirm those layers behave as expected when the media changes.
If you use vMix Playlist features to automate input changes, treat them as playback automation, not as a clock-based scheduler. Test the sequence of inputs and transitions in a normal run. Do not assume that a configured sequence will launch at a chosen hour or be restored as intended after Windows restarts.
Write down what a normal run looks like: which input is active, what the first and last list items are, whether the list loops, and what should be visible on the output. That gives you something concrete to compare with after a restart, rather than relying on the fact that the vMix window is open.
Save and verify the production
Save the production after configuring the List and any required transitions, overlays and output settings. Reopen the saved production before treating it as ready for unattended use. Confirm that it loads the expected inputs and media paths, and that the List still has Auto Next and Loop enabled.
Check any dependencies that might not be available at Windows startup. For example, a media drive may not be ready immediately, or a network share may require the expected user session. These are possibilities to test on your own computer, not claims that vMix will handle them in a particular way. If your media is on external storage, include a restart with that storage connected as it would be during normal operation.
A saved production and a running production are not the same thing. Saving preserves a configured state; it does not demonstrate that Windows will reopen it, that the correct user will be logged in, or that playback will resume at a useful point. Check the startup options documented for your vMix version, but do not infer from application options that the broadcast session itself is guaranteed to resume. (vMix options documentation)
Keep a copy of the production file and a short recovery note somewhere you can reach from the machine. Record the media locations, intended YouTube stream setup, checks to make after login, and how to start the broadcast manually if needed. This helps you distinguish a missing file or incorrect production from an encoder or YouTube issue.
For a channel that runs around the clock, consider the whole operational burden rather than only the media loop. A round-the-clock classical music channel workflow is a relevant example of why content continuity and broadcast continuity need separate attention.
Understand YouTube encoder start settings
Starting media in vMix and starting a YouTube broadcast are separate actions. The vMix guide for creating a YouTube Live Stream Now stream describes selecting or creating a stream and then using Start in vMix. Check the current procedure for your chosen stream setup, because an open production does not by itself establish that YouTube is receiving a live broadcast. (vMix YouTube Live Stream Now guide)
YouTube also has Auto-start and Auto-stop settings for encoder streams. When enabled for the relevant stream, these settings affect whether the encoder can control starting and stopping the stream. Confirm the settings in the Live Control Room for the specific stream you use; do not assume a setting from a previous event or another stream applies here. (YouTube Help: stream settings)
Treat the vMix Start action and YouTube's encoder settings as related but distinct parts of the workflow. The setting does not establish that Windows will relaunch vMix, restore the intended production or automatically connect the encoder. Check the stream key and destination privately, and avoid putting stream credentials in a recovery checklist that could be shared or exposed.
During a test, note what happens when vMix is running but the broadcast has not started, and what happens when the encoder begins sending. Use the Live Control Room to confirm the preview and status. If the event is not live when you expect it to be, follow the documented start flow and verify the outcome rather than assuming a looping List has started the broadcast.
Plan for update-triggered reboots
An update-triggered restart may leave you with several questions: did Windows finish its update cycle, is the expected user session available, did vMix open the saved production, and did the encoder reconnect? The sources reviewed do not document a complete supported Windows procedure that answers these automatically. In particular, they do not establish a universal startup task, launch delay, persistent authentication behaviour, preset restoration or automatic stream restart recipe.
Plan around that uncertainty. Before enabling unattended playback, decide who can check the machine after an update and how they will tell whether the channel is actually live. If no one is available at the time, make the eventual check simple: one place to verify vMix, one place to verify the Live Control Room, and the public watch page. Do not treat an update setting or successful sign-in as proof of recovery.
Schedule a controlled test at a time when an interruption is acceptable. Tell anyone who relies on the channel that the stream may be interrupted during the test. Use the same Windows account, production file, media storage, network connection and YouTube stream configuration that you expect to use in normal operation. A test on a different account or with a different production may miss the very dependency that causes trouble.
Keep expectations realistic about continuity. A restart may require an operator to open vMix, restore the intended production, verify playback and start the stream. If your channel needs to return without a person at the keyboard, your test must show that this happens on your particular machine and setup; documentation reviewed here does not make that outcome a general guarantee.
If Windows updates are only one of several interruptions you plan for, compare them with other failure modes such as power loss or network changes. Advice on backup options for power cuts in India can help frame the difference: a backup for one failure does not prove recovery from another.
Test the restart workflow on your machine
Use a controlled checklist and record what you observe. Do not rely on a generic script as proof that a restart workflow is supported. The exact result can depend on the Windows build, vMix version, saved production, account session, media locations, network availability and YouTube configuration.
| Checkpoint | What to verify | What it tells you |
|---|---|---|
| Windows ready | Update and restart cycle has finished; expected user session and network are available | Login alone is not proof of stream recovery |
| Production restored | The intended vMix production is open with expected inputs and output | The application is open in the correct state |
| List playback | The List is advancing and loops at the end | Media playback is working, separately from broadcast status |
| Encoder and event | vMix shows the expected stream connection and Live Control Room shows the relevant preview/status | The encoder is sending and the event state can be checked |
| Public viewer check | Watch page shows current video and audible sound | The programme is reaching viewers as intended |
Before the restart, note the expected starting condition. If you want to test recovery after a Windows update, first make sure the production and stream work normally. Then use a planned restart rather than waiting for an unattended update to reveal a problem. After startup, record which checkpoints passed and where an operator had to intervene.
If the production opens but the List is stopped, investigate the input and media availability. If playback works but the Live Control Room does not show the expected stream, check the vMix stream status, destination and applicable YouTube start settings. If the control room appears correct but the public page is wrong or silent, check the viewer-side output and audio. Change one part of the workflow at a time so you can identify what fixed or failed.
Repeat the test after meaningful changes, such as a vMix update, a change to the saved production, moving media, changing the Windows account or altering the YouTube stream setup. Keep a dated note of the configuration and observed result. That record describes your machine; it is not evidence that another version or computer will behave the same way.
Monitor recovery and stream status
After a real update reboot, check the layers in order. First confirm Windows has finished restarting and the expected network and user session are present. Then confirm vMix has opened the intended production, and that the List is moving through its items. A visible vMix window is not enough if it is the wrong production or the playback is paused.
Next check the stream status in vMix and the relevant YouTube Live Control Room preview. If the event is not live, use the documented start process and confirm the encoder settings for that stream. Finally, open the public watch page and check the current content, picture and sound. YouTube recommends checking the preview, confirming the stream is accessible and monitoring audio and video quality. Its streaming tips also recommend upload bandwidth headroom of 20% over the stream bitrate; treat that as a recommendation, not a guarantee of reliable service. (YouTube Help: live streaming tips)
Keep the public-page check in the routine even when the control room looks healthy. A control-room preview and the viewer experience answer different questions. Listen for missing audio, watch for the wrong input or a frozen picture, and make sure the current playlist item is the one your audience should see.
For ongoing operation, keep the recovery note close to the machine but protect account details and stream keys. If you want fewer local restart steps to manage, a hosted workflow such as StreamNeo can remove the specific burden of keeping your own computer on for an uploaded-video YouTube stream; it does not change the need to verify the channel and content are ready.

FAQ
Does Loop restart vMix after Windows reboots?
No. Loop controls whether a List returns to its beginning after playback reaches the end. It does not establish that Windows will launch vMix, restore the production or reconnect the YouTube broadcast.
Does YouTube Auto-start restore my production?
No. Auto-start and Auto-stop are YouTube encoder stream settings, not a Windows or vMix production-restoration procedure. Check the setting for the specific stream in Live Control Room and test the full workflow on your machine.
Can I schedule a vMix playlist for a particular time?
vMix says it does not support time-of-day scheduling. Its List and Playlist functions can support basic or continuous playback automation, but that is different from scheduling a production to start at a chosen hour.
What proves the channel is live after an update?
Check that the intended production is open, the List is advancing, the encoder is connected and the Live Control Room shows the expected state. Then view the public watch page and confirm the current video and audible sound. A Windows login or an open vMix window alone is not proof.
