Timecode Systems and GoPro’s Kolor team recently worked together to create a new timecode sync feature for Kolor’s Autopano Video Pro stitching software. By combining their technologies, the two companies have developed a VR workflow solution that offers the efficiency benefits of professional standard timecode synchronization to VR and 360 filming.
Time-aligning files from the multiple cameras in a 360° VR rig can be a manual and time-consuming process if there is no easy synchronization point, especially when synchronizing with separate audio. Visually timecode-slating cameras is a disruptive manual process, and using the clap of a slate (or another visual or audio cue) as a sync marker can be unreliable when it comes to the edit process.
The new sync feature, included in the Version 3.0 update to Autopano Video Pro, incorporates full support for MP4 timecode generated by Timecode’s products. The solution is compatible with a range of custom, multi-camera VR rigs, including rigs using GoPro’s Hero 4 cameras with SyncBac Pro for timecode and also other camera models using alternative Timecode Systems products. This allows VR filmmakers to focus on the creative and not worry about whether every camera in the rig is shooting in frame-level synchronization. Whether filming using a two-camera GoPro Hero 4 rig or 24 cameras in a 360° array creating resolutions as high as 32K, the solution syncs with the same efficiency. The end results are media files that can be automatically timecode-aligned in Autopano Video Pro with the push of a button.
“We’re giving VR camera operators the confidence that they can start and stop recording all day long without the hassle of having to disturb filming to manually slate cameras; that’s the understated benefit of timecode,” says Paul Bannister, chief science officer of Timecode Systems.
“To create high-quality VR output using multiple cameras to capture high-quality spherical video isn’t enough; the footage that is captured needs to be stitched together as simply as possible — with ease, speed and accuracy, whatever the camera rig,” explains Alexandre Jenny, senior director of Immersive Media Solutions at GoPro. “Anyone who has produced 360 video will understand the difficulties involved in relying on a clap or visual cue to mark when all the cameras start recording to match up video for stitching. To solve that issue, either you use an integrated solution like GoPro Omni with a pixel-level synchronization, or now you have the alternative to use accurate timecode metadata from SyncBac Pro in a custom, scalable multicamera rig. It makes the workflow much easier for professional VR content producers.”
