Just set the B-Chain input mode to “monitor feed” instead of “fixed format” – and you should be able to route your bus out to the B-Chain setup. In current versions of Resolve 17, B-Chain now works great in flexbus projects. Step 5 Output synchronized video in Blender.

Step 4 Switch to 'Properties' interface, and output synced video to MP4. 'Alt' + 'A' to preview the fix of audio delay. Step 3 Right-click the dark green track, keystroke 'G', then you can move & correct the audio track.

Hi everyone, just a quick update since this Insight was released. Step 2 Drag and drop your delayed video into the video sequence editor. Creating B-Chain monitoring presets for various formats and delaysĪs always – leave me any comments or questions below!.Measuring sync offsets using an iOS app.

Setting up a test pattern to measure sync, including patching Fairlight’s builtin oscillator.

The B-Chain tools in Fairlight allow you to build custom audio monitoring presets You can use the B-Chain to set up complex monitoring configurations and quickly switch between them. What if a simple delay isn’t enough? What about more complicated surround systems? That’s where Fairlight’s B-Chain tools come in.

If you haven’t used macro software before – check out my insights on AutoHotKey for Windows, and Keyboard Maestro for Mac to get up to speed. It gets a bit more complicated with multiple monitors – so I use Keyboard Maestro to automate changing the sync offset. What my audio video alignment test video does here is flash a white square for one frame with a 10ms length beep 520ms or 13 frames before the flash, then does this again 480ms or 12 frames before the flash, repeating until the beep and flash happen simultaneously and continue until the beep is 520ms or 13 frames after the flash. Once you know the offset, it’s as simple as dropping it into your preferences to get your audio and video locked into sync. It makes it easy to line up audio and video test patterns and tells you the exact offset in milliseconds. While there are dedicated hardware devices to measure video/audio sync, inexpensive apps on tablets and smartphones we already all own do just as good a job! Personally, I use the iOS app Catchin Sync.

This means it’s important to measure the delay for all your monitors and offset your playback accordingly. Sync is especially hard to get right – as just about every monitor has a different processing delay. The last thing you want during a grade review is a client asking ‘is this the right mix”’ or is that in sync or is it a bit off?’ Tutorials / Getting Sync’d Up: Advanced Audio Monitoring In DaVinci Resolve Getting Audio Monitoring RightĪudio monitoring isn’t something we think about very often in the grading suite – but when there is a problem, clients can notice.
