The hard part is actually sending the SMPTE.

SMPTE can also be used to sync video to a track played by a DJ. SMPTE is only used for very important show moments that are very difficult to time, or need to be 102% in sync. Every touring VJ still relies on his or her own timing and skills to run the majority of the show. It is very rare, even for top name DJs, to have a completely synced SMPTE show. It is purely a technique to make the playhead of a video clip run exactly in time with the playhead of an audio track. You will first need to have a finished video for a finished audio track for SMPTE to be of any use. SMPTE is not a magical tool that will let you sync up random visuals to random music. Need a different time offset or framerate? You can create your own at What SMPTE isn't wav file with 74 minutes of the soothing sounds of SMPTE at 25fps. A negative compensation can help with getting things perfectly lip sync again. Light travels faster than sound, so on very big stages the sound will take longer than the video to reach the majority of the crowd. Optionally you can add an delay compensation in frames to account for any lag that may occur in the signal flow. Note that the clip has to be active in a layer for it show in the output! The clip trigger itself is not sent via SMPTE. This way, you won't accidentally show the wrong show at the wrong time. When doing several timecoded shows on a single night, an often used convention is to let each show start at an offset of 1 hour. The offset is helpful to differentiate between tracks. You can select a starting timecode for a clip via the offset parameter. Note that SMPTE is not available on clips with an audio track. You can quickly switch inputs with the buttons in the bottom right. A special icon will appear in the layer strip to indicate that this clip is now listening for timecode. You can select your clips to run on SMPTE 1 or SMPTE 2 via the Timeline dropdown. Of course, you get the smoothest result if all the framerates are matched. Note that the framerate you have to match is the framerate of the incoming SMPTE signal, not the clip you are trying to sync to it. If you see a jump in the playhead at a regular interval of 1 second, you most likely have the wrong framerate selected. Most of the time this will be 25 or 29.97, but it can vary. Which SMPTE framerate is correct depends on the source of your SMPTE signal. The SMPTE tab can be found under View menu.īy clicking the cogwheel you can change the color of the SMPTE display. The SMPTE panel will now show the current SMPTE timecode for that input. Select the incoming SMPTE signal and required framerate for each input via the Audio tab of the Preferences. When your computer is connected to a valid SMPTE input, you can let clips run in time with it. Don't try it unless you are very stubborn and enjoy failure. Playing it over speakers and using the laptops onboard mic won't work. Playing an mp3 file with SMPTE on your iPod, connected via mini-jack to the line-in of your computer already is good enough. To connect a SMPTE signal to your computer, all you need is a source of SMPTE and a way to let your computer hear it.

So when you skip ahead in the SMPTE signal, or play it faster or slower, Resolume knows to update the playhead accordingly. Our ears can't hear this, but Resolume can. Every part of it sounds slightly different. Resolume can interpret this sound and use it as a clock. SMPTE is just an audio signal that sounds like 400 pigs screaming. Resolume Arena can listen to two SMPTE inputs simultaneously, so you can sync both tracks in the mix. Also it's used a lot by VJs touring with a DJ to sync pre-made visuals to a specific track. This is an often used technique to synchronize audio, video, lights, pyro and lasers during show moments or DJ intros. Resolume Arena can sync the playhead of a video to external SMPTE timecode. SMPTE Input is available on Resolume Arena only!
