Interlace/progressive detector

[demonwarrior]

does anyone know of a program or utility that can scan any movie file and report whether it is interlaced or progressive?

g-spot can do most formats.

It's called your eyes. There are plenty that can tell you if it was encoded as progressive or interlaced (DGIndex, Bitrate Viewer, ReStream, etc), but the best way to tell if the source is interlaced (has the fine parallel horizontal black lines during movement) is still your eyes. Just play it in a player where you can pause and advance a frame at a time, and where you can turn off any deinterlacing filters so you can see the artifacts. Or open a basic unfiltered AviSynth script in VDub(Mod), scroll to a place with movement and advance a frame at a time.

If you really want to try out an automatic interlace detector, then read this:

But after reading it, you might change your mind.

so what should i look for in Gspot to tell me whether it is interlaced or progressive?

Use your eyes bro its very simple.

well i dont have the time to watch each clip and movie

I think he was referring to the g-spot screen. There is a small indicator that lights up I/L if the clip has been encoded as interlaced. It's in the Pics/Frames/Fields section. It will also tell you whether it thinks it is Top or Bottom Field First. I can't vouch for it's accuracy.

both MeGui and AutoMKV has an interlace detector that can be runned stand alone, without encoding

tx will give it a go

tx will give it a go

And that's going to be faster than taking a quick look at the video?
