As for the method of file selection, File Per Segment can be set to 6 because this is the material of six lens.
image

You can also choose “Use Default Preset” , to use preset quick stitching, and find the appropriate shooting settings of Insta360Pro_3200x2400.grp in the folder, because the material was shot in 6K3d mode, with a resolution of 3200x2160 for each shoot. If the material is shot in 8K mode, you should select Insta360Pro_3200x2400.grp.

File import method 2:

This is the result of quick stitching. The following describes the functionality and settings of the various windows at the bottom.
image

Optimize the parameters of stitching in Positions. Generally, choose “Improve Offsets” and “Improve Angles” once for each.
image

Add boundary protection points in Edge Points to avoid stitching of key objects and people.
image

Click once on “Stabilize” to stabilize the video. The stability depends on the amplitude and speed of jitter, and this feature has better anti-shake effect in terms of walking jitter.
image

In Options, select Use Optical Flow, set 8-25 for Stitch Feature generally.

Convergence means parallax. In 3D mode, the parallax should be set to 60.
image

Generally after these steps, most of the material can be stitched well and exported. But there are also times when you come across a handful of tricky material, such as people’s face. So we add Edge Points, to offset the stitching edges to protect the characters.

Note that Feature Overlay and Camera Overlay should be turned on in the playback window.

Look at the lens and stitching edges.

In addition, you can add options in Optical Flow to adjust the depth of optical flow stitching.

Use the time interval for sequence settings of edit in and out tool, so that the segment exported is corresponding to the selected time interval.
image

File->Render, to open the Export Options interface, which can be exported after rendering, and select settings when exporting audio files such as no audio, independent audio files, and audio in movie.
