1, camera lens problem, resulting in distortion during shooting, resulting in distortion of the whole picture. I don't think there should be such a problem if the wedding camera is neither too new nor too old;

2. Transcoding errors caused by format conversion jitter are common. Generally, digital analog cameras are used in weddings, which is also commonly known as cassette recorders. After shooting, it can only be imported into the computer for editing through video capture, and the picture distortion is probably a transcoding error when collecting.

3. There was a transcoding error when editing and exporting. This is an error when exporting the video after editing the movie.

Solution: Generally, when the wedding film is ready, it will be shown to the person who took it at the scene, and it will be taken away when it is satisfied. After taking it away, the wedding will keep the materials in the computer for a period of time, so that they can be needed from time to time. However, the material takes up a lot of computer space, so it won't be kept for long. I suggest you go to them as soon as possible, maybe there is still a rescue. It is good for them to find out the reason and solve it fundamentally. If the material has been deleted, it will be in trouble. Using the material deformation function in general nonlinear editing software can make the film return to normal, but if you want to restore the original state, it depends on the degree of damage.

All right, that's it! Good luck! I'm exhausted from typing so many words!
