How to get a Sample File?

Use the same device to shoot a new video

Use the same device to shoot a new video or photo in the same format as the corrupted one.

Find a video or photo

Find a video or photo on the internet in the same format captured by the same device as the corrupted file.

Use a video or photo

Use a video or photo taken with the same device in the past.

For example, if you have corrupted MOV videos/ JPEG photos shot from Nikon Z 8 camera, to create a sample file, use the same camera to shoot a new video or picture in the same format as the corrupted one.
