This tutorial shows how to merge videos and still images together to get a perfect 360 video without any parallax.
Thanks to Mr. Antonio Victor Garcia-Serrano for sharing his videos and pictures.
The solutions used to create this tutorial are:
- Autopano Video Pro 1.1.0
- Autopano Giga 3.0.8
No parallax at all.. How is it possible?
Actually it's pretty simple, the idea is to shoot pictures as usual with a DSLR and a pano head (at the nodal point) then to shoot videos as previously done with pictures (at the same nodal point), with the same camera lens couple.
Step 1 - Extract the video frames
- Drag and drop the source videos into Autopano Video then click "Stitch as Gopro" to extract the video frames in the same folder as the videos.
Note: Autopano Video also creates a .pano file but we don't need in this specific use case.
Step 2 - Stitching time in Autopano Giga
- Import the 6 pictures and the 3 videos frames (previously exported from Autopano Video) in Autopano Giga.
- Be sure that all the images imported (pictures and video frames) have the same lens type (fisheye or standard lens).
- Then launch the Detection
- Open the Panorama Editor and check the overlapping between pictures and video frames using the Images mode.
- If it's possible clean up the panorama by hiding overlapped pictures. Of course do not hide the video frames they are the placeholders for the videos.
As you can see there, the panorama is quite dark.
- Enable the Level tool to enhance the global exposure. If you are not familiar with the level tools read first Panorama Editor - Color Correction - levels
Note: the leveling will be applied in Autopano Video too.
Step 3 - Set up the masks
This step is very important because you have to decide which part of the video frames or the pictures you want to keep or not. Basically you want to keep the video frames.
If you are not familiar with the masking tools read first Panorama Editor - Masking tool
- Enable the Masking tool and the Preview mode (close to the zoom icons)
As shown above, none of the video frames have been chosen because of Anti-ghost choice.
- Let's influence the antighost choice by adding Masking targets. In that case, only green targets are useful on the video frames for keeping them.
- The final result. The video frames are well blended with the still pictures (background):
Step 4 - Save the project
After the editing, save the .pano file in the same folder as the project resources.
Keep in mind that all settings (stitch, mask, projection) will be applied in Autopano Video.
If you need different settings, create several projects (one per cutscene) !!!
Step 5 - Go back to Autopano Video
- Import the project Menu File/Import Panoramas
- Select the reference panorama
- Click Render
Step 6 - Check the transition areas between videos and still pictures
If all is fine, congratulation!
If not, go back to Step 3 to add or remove green/red targets.
