So I’ve got a few questions surrounding upscaling of interlaced videos. First question being, how can I tell if the video is interlaced when importing it into TVAI? I don’t see anywhere that states it. Also, if a video is interlaced, what would the best way to upscale this be? I’m assuming I should …

Oh you’ll see the horizontal interlace lines if it’s interlaced. Just run a quick preview of some motion with the setting you want to use. If you don’t see those lines, it’s not interlaced.

Some here swear about external tools for deinterlacing first before processing such videos in TVAI. But I find that Iris LQ really does a terrific job deinterlacing and cleaning while simultaneously upscaling all in one pass for most content I have. If you see combing in motion parts of the video …

Thank you all for your suggestions!

Whether TVAI’s deinterlacing provides pleasing results depends on the material and how picky you are. Iris LQ does a good job of removing the ‘comb’ effect often seen with interlaced video that’s been converted to progressive. However, in my experience it loses detail and introduces artifacts when c…

to do a true compare of QTGMC vs. TAVI (Bwdif), you need to run the same model in the deinterlaced video. example of yours you need to run QTGMC then Iris LQ in v3.5.4 vs. TVAI 3.5.4 Iris LQ

Here you go, QTGMC + TVAI Iris LQ (again, version 3.5.4) added to the comparison: [deinterlace comparison 2] Comparing the two Iris LQ examples (the one on the far left, in which TVAI did the deinterlacing, and the one on the far right, where QTGMC handled it) I’d say the QTGMC-deinterlaced one i…

[image] a.molyneux-36619: Again, whether this matters enough to go through the extra step of deinterlacing via QTGMC depends on the individual. For me, I think it’s going to be worth it most of the time. so for me i got to that conclusion long time ago, that I why i told you to do that to tha…

Check out a program called Media Info. Its at MediaInfo and it will let you know if it is or progressives, and frame size etc

I also compared qtgmc, TVAI deinterlace, Dcomb, and others. When it comes to “weaving” interlaced lines, qtgmc clearly does the best job. What always bothered me was noise remove and lowering detail level qtgmc did, but with the right settings this does not happen and it keeps grain, which is why fo…
