Are there any endpoint exist that i can read frame rate, aspect ration and bit rate fields for video files ?
No, the Dropbox API doesn't offer an endpoint for retrieving these particular pieces of metadata for video files, but I'll pass this along as a feature request. I can't promise if or when that might be implemented though.
The Dropbox API does offer some media information via /2/files/get_metadata though, including dimensions, location, time_taken, and duration for video files.
