Day-of Checklist and Troubleshooting

Most stream problems can be found and fixed before the doors open. This page covers packing the equipment, checking the stream before it goes live, watching it during the event, and fixing the most common problems.

Packing an Event Kit

Regions that run many streams keep each field’s equipment in its own rolling tote, with a printed packing list taped inside the lid. One tote holds the camera, stand, network switch, cables, microphones, and adapters for one field; a two-field event takes two totes. This makes it easy to hand a kit to a different volunteer and know nothing is missing.

  • Label both ends of every cable with what it connects to.

  • Pack spare network cables, a spare audio-to-USB adapter, a power strip, and gaffer tape.

  • Coil cables using the over-under method. Alternate one normal loop with one loop twisted the opposite way. The cable then lies flat, uncoils without tangling, and doesn’t develop kinks. Never wrap a cable around your elbow.

Before the Event

  • Install OBS, plugin, and operating system updates at least a few days before the event, then run a test stream. Don’t update on event day.

  • Confirm the scheduled stream exists in YouTube Studio and the stream key in OBS matches it.

  • Confirm with the venue that the streaming computer can reach YouTube. See Network.

Before Going Live

  • Start a short test stream set to Unlisted and watch it on a phone, with headphones. Check that video, game sounds, and the emcee microphone all come through.

  • Check audio levels with the emcee talking and game sounds playing at the same time. Levels that look fine when the room is quiet can clip once the emcee starts.

  • Check each camera’s framing with the audience seated and field staff in position.

  • Open the OBS Stats dock and confirm it shows no skipped or dropped frames.

  • Start the local recording in OBS.

During the Event

  • Watch the venue projector, if it shows the program output. It is the fastest way to spot a bumped camera.

  • Glance at the OBS Stats dock between matches.

  • Switch to the Awards scene for alliance selection and the awards ceremony, and back to the Field scene afterward (Silver).

  • If the event will run past 12 hours, end the stream and start a new one at a break. See Streaming Platform.

After the Event

  • Stop the stream, then stop the recording.

  • Remux the recording to MP4 (File > Remux Recordings) and copy it off the streaming computer before packing up.

  • Split the matches and publish them. See Match Splitting.

  • Restock the tote and note anything that broke or ran out.

Common Problems

Problem

Likely Cause

What to Try

No audio on the stream

OBS is listening to the wrong device, or a USB adapter was unplugged and reconnected

In OBS, open the audio source’s properties and select the correct device again.

Audio is distorted

The level is too high before it reaches the computer

Turn down the venue mixer’s output or the audio interface’s gain, not just the level in OBS.

Stream is choppy or keeps buffering

Upload bandwidth is too low or is shared with other devices

Lower the bitrate in OBS. If the Stats dock shows dropped frames, move the streaming computer to a wired connection.

Stream stutters and the Stats dock shows skipped frames

The computer can’t keep up with encoding

Switch to a hardware encoder, lower the resolution to 720p, or close other programs.

An IP or NDI camera shows black

The camera lost power or network

Check the PoE switch’s port lights and reseat the camera’s network cable before assuming the camera has failed.

Projector shows nothing from a fiber HDMI cable

The cable is connected backward, or the fiber is damaged

Check that the Source end is at the computer. Then try a short HDMI cable to rule out the projector.
