Trying to Capture VHS as Interlaced (MediaInfor Reports "Progressive")

No it means the file is marked as progressive but the underlying data in the file is probably fine

Mediainfo just reports metadata. It does not look at the actual content. So it's just reporting how the file was encoded or flagged

An encoder has to be set to encode interlaced, and the field order has to be set. TFF or BFF

If the encoder that you are using doesn't give those options, it encodes progressively, even if the content is interlaced . The content might be ok, but that can still cause problems in other programs . You might have to manually interpet them in other programs like NLE's . Otherwise you get other problems. For example scaling will be done progressively instead of interlaced, and you will get artifacts

All this has has been discussed ad nauseum with the OP in previous threads. Hopefully, by now, he understands

Indeed. Why should he care what MediaInfo says about it? If he sees the interlacing, then it's interlaced and can take it from there for further work.

Again, ALL, I repeat ALL vhs signals are interlaced, even if the source material is telecined or PsF. Thus, you should ALWAYS be capturing it as interlaced. After it is captured, if you know for a fact that the source (prior to being put on vhs) was film (which is always progressive) it should be ITVC'd in software. And if it was progressive video (rare in the old days but certainly possible now), it should be deinterlaced.
If it was interlaced all along (e.g. from an old analog camera straight to vhs), it should likely remain interlaced - though the end result might be better served being progressive, depending on how it is applied. E.g. Dvd -> interlaced, YT -> progressive.

How it is captured, encoded/compressed, and stored depends on the device and software used, and the settings used.

If you are using a workflow that, possibly due to technical or programming inadequacies or shortcuts, automatically encodes interlaced as progressive, that's down to the workflow. Which can be changed now that you have been told more about how this is supposed to work.
