Media ID's & Hashes

The primary idea behind the file id's is to remove the chance for errors when searching for a movie. By removing the unreliability of a fuzzy text search we can provide much more accurate results.

Since we support numerous ID methods, it's important that your application is strict about the data posted to TMDb. Currently, we support the following 2 types.

File Hash
Based on OpenSubtitles technology. This hash id is based on the size + 64bit chksum of the first and last 64k. OST has samples of almost every popular programming language and is our recommended method for identifying files.

DVD ID
The DVD ID's are a disc ID originally generated by Windows which has become a bit of a standard. There is a library to calculate these ID's on other systems, which you can find here.
