Afterediting interlaced Pal files, if you choose in PRODUCE files with
extension H 264 - MP4 the presets have a scan profile of the PROGRESSIVEtype.

Alternatively, you need to build a customized profile with a INTERLACED setting.

Which of these options is the most correct? W 10 64 , pc Dell XPS 8000 - core i7 2,8 GHz--ram 6 MB--GEFORCE GTX 1050TI 4GB - SSD 256 + 2x630--area Pal

In television terms, all HDTVs are progressive scan displays, so even if the signal being sent to the device is interlaced, the HDTV will convert it to progressive scan for display on the screen. The answer to your question therefore, is that it depends what you're going to use your 'produced' file for. If it's to be played back on an HDTV, then go with Progesssive.

Files have a familiar content and are intended for storage.
In the future they will be played on HD TV.
Perhaps this is why PD chose PROGRESSIVO as a preset? W 10 64 , pc Dell XPS 8000 - core i7 2,8 GHz--ram 6 MB--GEFORCE GTX 1050TI 4GB - SSD 256 + 2x630--area Pal

Maybe this will help. Interlacing was required for old-style (preHD) TVs, and interlaced clips made with VCRs, camcorders and early versions of digital recorders like TiVo only have 1/2 the information that progressive clips contain. That made any motion in the clips look jagged.

Since all display devices are now digital, there is no longer any reason to store (or even record) interlaced clips UNLESS you specifically expect to watch them on an old, analog monitor/TV.

I understood, in the future I will resume digitally progressive.
Thank you. I greet you.

All the new HDTV's, based on LCD technology, are in fact small computers (like the cellphones) with big monitors, all capable of displaying 1920x1080p (or 720p for the cheapest ones) at 60Hz progresive.

There is actually no reason why anyone would record in 50Hz anymore, PAL and NTSC "standards" were purelly analog standards, practically dead in Ano Domini 2018.
