the jagged eges should not be there if smart deinterlacing is enabled. upscaling just adds pixels to the image after the edges have been removed, to make it a HD or 4K image.

 

is there some other "smart deinterlacing" setting that i'm missing, other than "Smart adaptive (GPU only)" in the project settings?

@Pea-Hicks Hi, what am i missing here? I assume i'm doing something wrong as i see no jaggies, , earlier you say that you tried setting project and render settings to match the source

I dragged that file onto Vegas19, clicked Yes on the pop-up to match source material

This is the project it gave me

I rendered using AVC, this template i have for 4:3, i just changed the width & height

this is the file that render created

On my 32" 4k screen VLC player full screen

& Windows Film & TV full screen

This is your orig AVI in VLC Player full screen

Just out of curiosity I changed the project to UHD/4k 3840 x 2160

Rendered AVC 4k

this is the file full screen VLC Player

This is that 4k file

Thanks so much for trying out my file! I reviewed all of your screenshots and found the one setting I hadn't messed with- you have the de-interlace method set to "blend fields." i haven't tried that setting for a long time, and just sort of forgot about it as an option, as somewhere along the way i got the impression that it's inferior to the other settings. Well, that seems to have (mostly) cleared up the jagged edge problem. The only thing is that I'm still seeing some interlacing artifacts, particular during motion, and also the image is softer overall. But I tried adding a little sharpening, and that gets me a reasonably acceptable result relative to the render time. It still doesn't hold a candle to the result I'm getting with Topaz, but the render time is the trade-off I guess...

@Pea-Hicks Follow the directions in your Vegas Help to the letter; I cannot stress this enough. Then if there is an ambiguity, it is because the directions are wrong or ambiguous, and it would then be reported to the development staff as such. Sound reasonable?

@Pea-Hicks Yep, I set the project to your orig post 1920 x 1080 Smart adaptive & got jaggies, i was doing that while you wrote the comment above 😉

yep Smart vs Blend

Hi, I've read all the relevant help files and don't think I've missed anything...

@Pea-Hicks I did all 4 options, None is a bit crisper but there are small jaggies 🤷‍♂️

Hopefully you can tidy it up like you mentioned with sharpness etc.. 👍 4am i'm of to bed 🏃‍♂️😁

Well, I've tried bits of various videos using "blend fields" and... while the first video I tried looked pretty good, some of the others look pretty awful... especially relative to the results I'm getting with the same videos using Topaz...

@Pea-Hicks Oh that's not fair, sods law init, best of luck 🙋‍♂️👍

OK, so here's a couple more tests. This first one is using the "blend fields" setting that had looked promising at first...

and here's the same clip processed w/ Topaz:

https://www.dropbox.com/s/9ryty17qq0ck85d/topaz%20test.mp4?dl=1

note that this clip is from VHS. I've cropped it to 16:9 because the VHS tape itself has some garbage at the top and bottom of the frame.

@Pea-Hicks Hi, yeah Topaz does a better job, can you upload the orig unaltered clip?

The test source you've been using is confusing to me, because I'm not sure how to distinguish the interlacing from aliasing at low resolution. Without motion, its usefulness for testing may be limited (and confusing) since combing is not evident.

I bet you missed these tests, done with real 1080i 59.94 source. Look closely at the violin strings:

And here's some different footage that makes an excellent source for testing deinterlacers. I use it a lot.

the raw capture for that particular video is a 98gb .avi file, over an hour in running time, that's really too big for me to post.

thanks! though i'm really only interested in what I can do with interlaced SD sources, as that's the material i'm working with.

Yes. I pointed you to the 480i to 720p example in my Signature, but I don't know if you actually looked at it.

I did, but wasn't able to get the same type of result by following your suggestions.

I followed the Vegas Help instructions to the letter, but added a Light Unsharp Mask before Upscale. That's it, best of success going forward.
