I just got a subscription today for Topaz Video, and am trying to deinterlace some old footage. Can anyone give me some tips on improving my current workflow. Source footage is 720x480 DV 29.97fps Interlaced Bottom field first, DV .avi I’m converting it into: 720x540 square pixel, progressive 59…

Why are you using frame interpolation? Is the original footage not 59.94 discrete (different) fields per second? If you have combing artifacts, then it sounds like it is 59.94 fields per second, so you don’t need to use frame interpolation (just turn off frame interpolation by pressing the blue tog…

The original frame rate is 29.97fps 720x480. I read that doubling the frame rate is appropriate for the best outcome, so that’s why I turned on frame interpolation to 59.94 (720x540 square pixel). I tried keeping the frame rate the same for the output and it wasn’t as good as doubling it.

What you read was probably referring to bob deinterlacing, not frame interpolation. Bob deinterlacing doubles the framerate by separating the fields into whole frames (so 29.97fps becomes 59.94fps) without the use of frame interpolation. This should give better results, because you won’t have to co…

I actually tried to avoid switching on the frame interpolation section, but there was nowhere else where I could change the frame rate to 59.94. Nowhere in the enhancements section, or in the codec settings. Do you know where I can change the frame rate without turning on frame interpolation?

Yes, i’ll append a screenshot here in a minute. EDIT: Actually 2 screenshots: If you’ve set the video to be processed as interlaced in the enhancement section, you can change the framerate to “2x Deinterlaced” in the frame interpolation section without turning on frame interpolation (notice the t…

Try that, but also try Proteus with manual settings at something like: [{66D81ED9-123B-4D0B-B700-1726B9AE58E2}] Proteus 4 was made years after Dione and is more true to the source video in all of the movies I have tried.

yup, do not frame interpolation, first step is always deinterlacing! I recommend Hybrid QTGMC with this settings , set “final temporal smoothing” to 0 (not as in my screenshot). When deinterlaced result produces to much halo effects, then you can enable final temp. smoothing by set it to 1. Try firs…

Do not deinterlace with Topaz. There’s a bunch of free tools that do it better and have a range of controls. As for me, I choose Hybrid: [image] Topaz Video 1.0.0 (New Studio Release) Releases Here are my settings in Hybrid (it’s totally free) https://www.selur.de/ Outp…

Thanks, I downloaded Hybrid and put these settings in. My footage is NTSC. In the Crop/Resize, I made the output 640x480, square pixel. Is this OK, or should I be going for 720x540 square pixel? I’m putting this through Starlight Mini for 4x upscale later. [image] [image] [image] My inpu…

You have to convert to square pixel before starlight mini.
