Then either play back that same video and try to sync it (theoretically possible, but to me everything starts to sound the same after a couple of tries) or record one of the sync videos above playing on your screen (easier, but you get an additional error of about ± ½ screen frame period or so). I mean, you could if you really wanted to? But you probably don’t, given the hassle.Īssuming only a constant offset and no wobble, record a clapper on your camera, then use a composition tool to measure the offset between the audio graph and the video frame (up to ± ½ camera frame period, inevitably).

Download the appropriate frame rate video, and you can download these in 4K or HD. You can play these from YouTube directly, however I recommend against that as there's no way to know if YouTube is delivering the video perfectly in sync. If your hardware programs the delay in milliseconds, use the chart to see how many seconds/milliseconds the delay is. Add a four frame delay into the hardware. For example if the red dot is at the –4 mark, then your audio is four frames BEFORE the video. Place the playhead there and look at the video wherever the red speaker dot is, indicates how many frames you need to adjust.
It's helpful to run it for more than just a couple of beeps so you can verify there is no variance from the beginning to the end of the clip.
Ensure that the microphone is in (close to) the same position it will be for the production, that the microphone can clearly pick up the BEEP from sync test video, and that you can clearly see the sync test video on camera.

Position your laptop/tablet where the talent will be, play back the downloaded sync test (full screen and full volume is best), and point your HDMI camera at the screen.It's critical that you use the matching frame rate to your production, or this won't work! Download the video(s) for the appropriate frame rate to a laptop or tablet (the bigger the screen, the easier it will be to see this).I made a video that explains this… check it out here. These custom videos allow you to measure the delay so you can program it into your hardware.

If you're using a professional sound mixing board, the board can typically program a delay into it in milliseconds, so the audio actually arrives to your switcher / streaming hardware at the same time as the video.

Devices like the ATEM Mini Pro have the ability to program in a delay for the audio, so is in sync with video. However when using an HDMI camera in a live production situation, if you're mixing video from the camera and audio from another source, the audio will generally be in real time while the video will not, resulting in an audio/video mismatch. When recording video, this is irrelevant. Why you need theseĪll HDMI cameras have a slight delay between realtime and what's actually output over HDMI this is simply inherent in HDMI processing and is unavoidable. These are my own custom audio sync tests, provided for you to freely download at all common frame rates of 23.98, 24, 25, 29.97, 50 and 59.94 fps. Apple has been notified of this problem, and replacement files are on the servers. The new exports are all HEVC, which are (verified!) perfectly in sync. The master files were perfect - the H.264 were all shifted by a frame (and in some cases, more!). It turns out this is, as far as I can tell, a bug in Apple Compressor. This is horrendous and I apologize profusely. UPDATE: In March 2021, it was brought to my attention that the downloaded files were actually OUT OF SYNC.
