It is also good enough to sync up with the studio master audio, which I use to render the the completed project (obviously I mute all the in camera audio because it's not as good as the studio audio).Īs I said, I'm really surprised no one else is using this. I am working on a project right now where I have used 25 fps, 30 fps and 50 fps footage, and successfully synced it all up using this technique. It is similar enough for the sync algorithms in Resolve to successfully sync it with other footage (either recorded at normal speed or at higher frame rates). Obviously there is some distortion, but this is fine because I am not using it as final audio, only for syncing purposes. When the audio is slowed to 50% (half as fast) it sounds roughly like the original audio. I then slow the audio recorded in camera to 50% (half speed). In post I change the framerate of the video so it plays back at 25 fps. The talent mimes along, desperately trying to keep up with the fast playback. I record this fast audio in camera at the time of filming. The audio playback is also speeded up to 200% (twice as fast). For slow motion effects I film at 50 fps (twice my project frame rate). It works fine as a syncing tool (I'll say it again - syncing tool).

I'd like to avoid these additional steps and do it in the media page. But currently I have to take the clip into a timeline, change the clip speed, render and import back into the media pool. By slowing down both the video and the audio, the speeded up audio distorts back to its original speed and Resolve can sync with other clips (very clever of Resolve). I often use higher frame rates as the talent mimes to a speeded up audio track. Why do I want to do this? I film music videos.

I want the audio to be distorted as it is stretched. I don't want the audio to maintain pitch. How can I change the frame rate and audio duration at the same time in the Media page so the audio and video are the same length?

But this does not change the sound, and hence the audio is a different length to the video. I use this to obtain slow motion effects (I know there are other ways, but this is my chosen approach for various reasons). This will write Pan automation to the Track, and when played back the Pan automation curve will change to green (to indicate Read Mode is active).I often use the clip attributes window in the Media page to change the framerate of clips, e.g. While writing automation, the Pan curve on the Track will turn Red (to indicate Write Mode is active). Then just move the Pan blue dot in the Panner window for precise control of Pan movement, or just drag the Pan blue dot on the Mixer channel Pan graphical display (as discussed earlier) for less fine control. Place the Play Head where you want to record automation from, and hit play. On the Channel you wish to automate, set the Automation view on that Track to Pan (so you can see the automation being written in real time as you move the Pan blue dot:

Or, click drag the little blue square in the Mixer channel Pan graphical display (no need to open the big Panner window).Īutomate the sound effect moving from back to front by first clicking the Automation button in the Transport (last icon on the right next to the Loop button) and setting Touch Mode to Latch: Simply Pan the source sound effect to where your 'starting point' will be, by either double clicking the Pan graphical display on the appropriate Mixer channel and opening the Panner. Create a Mono Audio Track on the Fairlight page (right click > Change Track Type To > Mono), along with a 5.1 Master Buss (Fairlight menu > Bus Format > Main > Set Format to 5.1 > Name it).
