We can make a brief description of the panorama. Splice multiple pictures or videos according to certain projection methods. Such as Equirectangular, Mercator, Equisolid projection, etc. Finally, it forms a 360-degree image around the observer.
1. Revealing Mistakes:
VR captured everyone and things in the scene in all directions.
2. Lighting:
People want to shoot artistic effects and specific effects. They want exquisite and high-quality picture. Lighting is indispensable. Traditional lighting has met with challenges.
3. Movement:
You should know how to use traditional track, rocker arm and other equipment. They ensure the erasing quality of post-production. Many directors have to learn to master DT process again.
4. Perspective:
Some people say that the challenge of VR movies is one take. This statement is wrong. The VR movies should use montage to describe things. Yet the lens should not be too fragmentary. It ensures the rhythm. And at the same time, it leaves more time and space for the audience.
5. Performance:
This is a big challenge. All the actors in the frame should perform simultaneously. All the teams should cooperate simultaneously to complete live special effects.
1. Splicing:
Autopano Pro can't complete to splice. There are some high-demand productions. You should master the professional production process such as Nuke or AE.
2. Chromatic Aberration:
People may use all-in-one machines or professional split machines. Color difference is inevitable. Practice makes perfect. Practice slowly. The later period will remedy the mistakes of the earlier period at any time.
3. Synthesis:
Full-motion video cannot directly synthesize subtitles and packaging elements. You should correct distortion according to position.
4. CG Visual Effect:
You may encounter a long-span CG visual effect from front to back. The workload and difficulty will be great.
VR video is shot 360 degrees in all directions. You need a camera equipped with multi-directional cameras. Such as Google YI JUMP VR camera, Jaunt ONE VR camera, Nokia OZO panorama camera, etc. The camera lens is fixed focus. There is no close-up and walking shift in traditional movies. Therefore, you should set the movement track of the camera in advance. They can decide whether you can produce VR video with good quality.
Secondly, you need the totally enclosed shooting environment. It provides a more real shooting environment. The environment reached by the camera cannot contain people or things unrelated to the video. Even the director should stay away from the shooting scene. Or they should make appropriate camouflage to avoid piercing. So, the video shooting set is important. Of course, not all closed environments are suitable for VR video shooting. Only those backgrounds with strong sense of substitution will bring immersion to VR users. They show the beauty of VR video.
Finally, post-production of VR video is crucial. The production and splicing of VR video affect the look and feel of the video. You should do rehearsals in advance before shooting. It is best to pass at one time when shooting.
