Input Video File
| The input video file in any of the supported video file formats, including PS, TS, MPG, MPEG, MP2, MPG2, MPEG2, MP4, MPG4, MPEG4, H264, VOB, and M2TS. | File |
Output Folder
| The file directory where the output images and metadata will be saved. | Folder |
Image Type
| Specifies the output image format.
| String |
Maximum Overlap Percentage
(Opcional) | The maximum overlap percentage between two images. If the overlap between a candidate image and the last image written to disk is greater than this value, the candidate image will be ignored. The default percentage is 100 percent, which writes all images to disk. | Double |
Require Fresh Metadata (Opcional) | Specifies whether video frames with associated metadata will be extracted and saved.
| Boolean |
Minimum Time Between Features (Opcional) | The minimum time interval between video frames to be saved. If this is not specified, all video frames will be saved as images. | Time Unit |

Resumen
Extracts video frame images and associated metadata from a FMV-compliant video stream. The extracted images can be added to a mosaic dataset or other tools and functions for further analysis.
Uso
This tool works with archived video data only. Live stream videos are not supported.
Images from a FMV-compliant video stream will be extracted and stored in a directory in TIFF, NITF, or JPEG format.
Metadata associated with the video imagery will be written to a comma-separated values file (.csv) in the same directory.
