To stream a prerecorded video to YouTube Live using AWS, store the MP4 in Amazon S3, configure AWS Elemental MediaLive to use that file as a video-on-demand input, and send MediaLive’s live RTMPS output to the stream URL and key shown in YouTube Live Control Room. The video is not streamed directly from its S3 link: MediaLive reads the file and creates the live feed for YouTube.
What you need before setting up the AWS workflow
- A YouTube channel that is verified and has had no live-streaming restrictions during the previous 90 days. YouTube’s live-streaming eligibility guidance describes these requirements.
- An MP4 video uploaded to an Amazon S3 bucket that MediaLive can access.
- An AWS account and a MediaLive configuration available for your account and chosen AWS Region. Confirm current regional availability before designing the channel.
- A scheduled YouTube live stream, or another live event set up in YouTube Live Control Room, to obtain its actual ingest URL and stream key.
For a typical prerecorded MP4 workflow, S3 is the source and YouTube is the destination. MediaLive accepts MP4 as a VOD input and can deliver an RTMP or RTMPS output to a compatible server. It supports RTMPS output but not RTMPS input, so do not try to use YouTube’s ingest URL as the MediaLive source. See the MediaLive input-format documentation and supported output protocols.
Choose a setup path
Use the MediaLive workflow wizard
AWS documents a workflow wizard that can use an MP4 on S3 or HTTP as its source and YouTube as an output. It is a lower-touch starting point if its available options fit your account and configuration. The precise steps and options may differ by account or setup; verify each generated source and destination before starting the channel. See AWS Elemental MediaLive workflow wizard.
Configure the input and output yourself
For a manually configured channel, create or select an S3 MP4 VOD input, then create a MediaLive channel with an output group and destination that matches YouTube’s ingest details. AWS gives an example secure S3 location in the form s3ssl://bucket/object. Use the exact bucket and object path for your file, and ensure the input has permission to read it. Do not treat the S3 address as a YouTube stream URL.

Set up YouTube Live and get the ingest details
- In YouTube Studio, open Live Control Room and schedule or create the stream. Complete the event details and configure visibility and other options for your intended audience.
- Open the stream’s encoder or stream settings and copy the displayed stream URL and stream key. Treat the key like a password: anyone who has it may be able to send video to your event. Do not publish it or include it in screenshots.
- Prefer the RTMPS URL revealed through the lock icon in Live Control Room. YouTube recommends RTMPS, which encrypts the RTMP connection using TLS/SSL. Use the URL YouTube actually provides rather than assuming a server address or copying an example. See YouTube encoder settings and stream setup.
- In MediaLive, configure the output destination using the YouTube-provided server address and key. Depending on the configuration interface, the destination is assembled from the protocol, server address, port, application name, and stream name. Copy the values from YouTube exactly; do not reuse example values from AWS documentation.
Choose output settings YouTube can accept
Use a consistent output that suits the source file and the available AWS output configuration. YouTube’s encoder guidance for ordinary SDR RTMP(S) streams supports H.264, H.265/HEVC, or AV1, constant bitrate, and frame rates up to 60 fps. Its H.264 examples recommend 10 Mbps for 1080p30 and 17 Mbps for 1080p60; these are platform settings, not a promise of a particular viewing quality. A higher bitrate is not automatically better if the source, channel configuration, or delivery path cannot sustain it.
- Resolution and frame rate: Select an output that matches the source where practical. Avoid upscaling a lower-resolution file on the assumption that it will create extra detail.
- Codec: Choose a codec supported by the selected MediaLive output configuration and YouTube’s current ingestion guidance.
- Bitrate: Use constant bitrate (CBR) and a value appropriate to your chosen resolution and frame rate. The H.264 examples above are reference points for those specific formats.
- Keyframes: Set a two-second keyframe interval where configurable; YouTube recommends two seconds and says not to exceed four seconds.
- Audio: Check the audio track is present, audible, and aligned with the video in a test. Use settings supported by your encoder/output path and YouTube’s current guidance.
Read YouTube’s current recommended encoder settings, bitrates, and resolutions when choosing the final configuration. YouTube transcodes live input into multiple output formats for viewers.
Preview, start, and monitor the broadcast
- Test with representative content. Before the event, test a clip with similar motion and audio to the actual video. Confirm the S3 object is readable and the MediaLive output reaches the intended YouTube event.
- Allow setup time. YouTube recommends setting up an encoder event at least two hours in advance and starting the encoder at least 15 minutes before the scheduled start. These are operational recommendations, not a guarantee against delays.
- Check YouTube preview. Start the MediaLive channel and wait for YouTube Live Control Room to show the incoming stream preview. Verify picture, sound, and stream health before making the event public or starting it for viewers.
- Monitor during the stream. Keep Live Control Room and MediaLive channel status available to check for warnings or interruptions. Review YouTube’s displayed stream-health messages and address the indicated issue.
- End the event and stop AWS resources. End the live event using the relevant YouTube controls, then stop the MediaLive channel when it is no longer needed. Confirm that any associated resources you started are also stopped so they do not continue running unnecessarily.
YouTube documents automatic archiving for streams shorter than 12 hours. Do not assume the same behavior for longer broadcasts; check the event and archive status after ending the stream. See YouTube’s live stream archiving guidance.

There is no single reliable AWS price for this workflow without selecting a Region, channel configuration, output settings, and runtime. Current India Region availability for the specific MediaLive configuration also needs confirmation. Before launching, check AWS’s current regional service availability and use its pricing information for the exact channel setup and expected operating hours. Include the runtime of the MediaLive channel and any related resources in your estimate; do not infer a monthly cost from the video’s file size alone.
If you instead send the video from an encoder running on a local computer, the local upload connection must sustain the selected output bitrate. For a cloud MediaLive path, verify the source-access and AWS configuration rather than assuming your home upload bandwidth determines the outbound stream. YouTube recommends testing the full workflow before the scheduled event.
Common problems and what to check
- YouTube does not show a preview: Confirm that the MediaLive channel is running, the output destination uses the exact current YouTube ingest URL and stream key, and the selected event is the one you intend to broadcast.
- MediaLive cannot read the MP4: Check the S3 bucket and object path, the secure S3 URI format, and permissions allowing MediaLive to access the object. Confirm the file is an MP4 VOD input rather than a live input.
- Connection or protocol errors: Ensure the destination protocol matches the actual URL from Live Control Room. RTMPS is the recommended YouTube ingest option. Do not confuse RTMPS output support with input support: the MP4 comes from S3, not from an RTMPS source.
- Warnings about stream health or quality: Compare the configured codec, resolution, frame rate, bitrate, and keyframe interval with YouTube’s current recommendations. Check the preview and Live Control Room messages rather than raising bitrate blindly.
- Video has no sound or audio is out of sync: Inspect the source file’s audio track and test a representative segment through the complete workflow before the event.
- Unexpected AWS charges continue after the broadcast: Check whether the MediaLive channel or related resources remain active, and stop resources that are no longer required.
