You know, I'm starting to wondering if a project I'm working on is in this format.

I assumed it was a standard blended fields PAL video, but the run time is still shortened.

How do you identify this type of video? It still has blended fields, doesn't it?

Edit: Never mind, figured it out. For others who want to know the difference, apply bob to your video:

2:2:2:...:3 (aka 12:1 and 24:1) will show 11 clean fields in duplicates and then a field in triplicate. No blending.

Blended fields have slightly more than half of its fields blended (double image). Srestore is your best bet for this.

As far as the project I'm working on? I think Imdb has the runtime wrong.
