Configure stitching settings:
When selecting stitching mode, remember that optical flow stitching can handle parallax very well but is time-consuming. Scene-specific template stitching is much faster but seams will be visible when objects are too close to the camera.
Sampling type affects the accuracy of stitching. There's little difference between "fast" and "slow", but "fast" is around 5 times faster than "slow".
Blender type enables stitching hardware acceleration; it is dependent on the performance of your computer's graphic cards. Nvidia users can choose "cuda" and Mac users can choose "opencl". If a crash occurs during hardware acceleration, choose "CPU" for a stable stitch.
Gyroscopic stabilization indicates whether the stitcher should use the gyro data to correct the horizon of the video; this option is disabled when stitching stereoscopic videos (to prevent generating incorrect parallax).
When stitching monoscopic video under 4K x 2K or stereoscopic video under 4K x 4K, you can enable hardware encoding to accelerate the encoding.
When using high-performance computers, users can choose to use hardware decoding to decode all 6 original video files, but most computers can use hardware decoding for a maximum of 3-4 original video files. You should modify the number to find out the maximum hardware decoding capability of your computer.
