I've extracted some 60i footage from my Sony Handycam HDR-CX150 that records AVCHD (.MTS) files. I believe it records in 1440x1080 and it stretches it out to a vertical 1920x1080 resolution with a 1.333 pixel aspect ratio. I am importing my footage into Premiere Pro 2024 and I want to upload it to Youtube, with an intentional interlacing effect.
My bigger problem is that I want to extract the interlacing effect from this footage and make it viable (such as the video seen here). So, I interpreted my footage as Progressive Scan (instead of Upper Fields, which would get rid of the interlacing lines) and in my sequence I changed Upper Field First (which would have done the same thing as said before) to Progressive Scan. (below)
It seems to do the trick, but the problem is that when it is full screen, the interlaced lines are too thin (pixel-by-pixel on and off) and they kind of destroy my exported video into a mush of crushed bitrate. (below)
I looked at the preview screen of my export window for the crushed footage, and it looked EXACTLY how I wanted it to; the lines weren't too thin, but not too thick either. (below)
So then I got the idea of exporting my footage as a smaller resolution, so that the lines may become thicker and the effect will be less harsh. But for some reason, when I export it (say, at 1080p) and open it in preview, the interlaced lines almost look greyed out and not at full opacity, which tells me I'm doing something wrong with changing my resolution. (below)
Perhaps I'm supposed to export at some specific resolution that gives me those desired lines I saw in the preview? Looking for answers. Thanks!

The interlaced fields should always render correctly regardless of what the Source panel or Program panel looks like. As you've noticed, too thin for what you are looking for.
Try the Venetian Blinds effect.
Duplicate the video clip above itself in the Timeline.
Nudge the duplicate a few frame left or right so that it is playing a few frames earlier or later than the original below it.
Apple Venetian Blinds (Effects > Video Effects > Obsolete > Venetian Blinds) to the duplicate and set the Effect parameters as follows:
- Transition Completion: 50%
- Direction: 90 degrees
- Width: 10 to 20
- Feather: 0
Make sure that the Program magnification is at 100% while making the adjustments.
I think between adjusting Width and maybe also Feather you should get close to what you are describing.
Thanks for the reply. So is the only way of recreating the thick scanlines shown in the preview box by re-interpreting my footage into a normal deinterlaced sequence, and then artificially adding those lines with Venetian Blinds?
To clear up any confusion, the "thick scanlines" that are in the preview box in the export screen are showing when the interlacing pattern (at full screen) is perfectly every other (even/odd) pixel. So when I fullscreen the video window in the sequence with my interlacing settings, the lines are very thin (which is what I don't want). However, when I go to the export screen to export my video, the preview box looks completely different from the view I just saw in the sequence video; the lines appear much thicker. I am more fond of this look than the one in the sequence, because the interlacing looks a lot more natural.
Additionally, I apologize if I've asked this question again and again, but do you know how Premiere constructs the preview box in the export screen? It looks perfect in the preview box, and I think it would be better for me to just recreate whatever settings it's previewed at (in the export window) within the sequence/export settings, instead of having to resort to venetian blinds.
