To clarify/expand on this, the following are some examples I can think of:
- Different files with the same video encode but different audio. e.g. AC3 2.0 v.s. DD 5.1 v.s. DTS-HD-MA
- Different files with the same video encode but different subtitle options. e.g. French v.s. German
- Different files with the same video encode but from different sources. e.g. DVD, Web-Dl, Bluray, UHD. These could all be encoded to the same resolution and bitrate but would vary in quality due to oversampling.
- Different files with different video encodes but the same bit rate and resolution. Despite the same average bitrate and resolution, these could vary drastically in quality
In all these examples the different files would appear identical in the current “Play Version” dialogue.
This is to say nothing of the scenarios where the encode bitrate or resolution might be different but it’s still not enough to easily identify the different files.
Filenames provide a wealth of information which would enable easy identification of the different encodings.
