How to determine m2ts file order

[bluesk1d]

When backing up a BD disk by re-encoding to another format, one must first find out the correct order of the m2ts files. Some movies make that quite a pain with lots of random files of different sizes that are sequentially out of order. What is the magic of determining the correct file order (or is this a painstaking manual process)?

If you're serving the video with an Avisynth script, just use the standard trick with SeparateFields(). I'd hardly call it painstaking, but I would call it reliable. :)

Hmm maybe I need to be more specific. Were you under the impression I meant field order? What I mean is some BDs have their main feature split up across a dozen or more m2ts files of varying file sizes and they do not go in order. For example, the main movie might actually cosist of 00047.m2ts+00034.m2ts+00061.m2ts so on and so forth for 10-20 files. It is easy to recombine them but you need to know the correct order. What is the way people are using to figure out what order the authors defined for playback? There must be some file somewhere on the disc that tells the player which order to play the m2ts files for proper playback. Ratatouille and Deja Vu are examples of this method (with Ratatouille being the worst with multiple decoy files).

Oh, sorry, I read it too quickly. I don't know anything about your real question.

You need to look at the .mpls files with a hex editor.

This is my big problem too - the Blu-Ray programme chain (pgc).

In Black Hawk Down for instance I had to Tsremux to two ts files and then join them. In Deja Vu, instead of one or two very large m2ts files there are about 10 ranging from 2GB to 5GB.

There is a program called pcg.net that works on standard DVDs to determine the correct order. In one of the multiple directories on a Blu-Ray disc, one of the files must explain the correct pcg/order.

Does anyone know how to solve this problem? To start thinking about reading files with a Hex editor begins to make the whole exercise too much of a pain
