V.3.3.x not as good as v 2.3.x

I used the v 2.3.x before and it can improve the video quality for me. But I can’t see any good results from v.3.3.x. I uploaded a comparison. The right one after AI processing is not even as good as the original ones. Any idea?

your picture on the right looks interlaced to me

All right. Please tell me what setting I should choose so that the right one is better, without “interlace”.

The input file has some interlace because they are old videos. What setting I should choose to make it better?

Read this post for ideas:

I read the whole post and could not obtain any ideas. Please help!

I am not sure what you are asking. you are asking how to deinterlace in TVAI or you asking how to deinterlace external to TVAI that you would be able and process it in TVAI as progressive video?
but one thing is certain, you must deinterlace your video before you can process it further.

once you are more clear, I can provide you solutions to your needs.

The issue that I just found out is that if I convert the original 480p low grade video (with interlace) to 720p or 1080p (still, with interlace) using Microsoft ClipChamp, then none of the deinterlace algorithm of Topaz works. But if I apply Topaz software to the original 480p video, it works.

Can you explain this strange behavior?

I am not familiar with the Microsoft tool, but my guess is that it doesn’t deinterlace your video. only converts it to progressive scan without deinterlacing it 1st. basically it screws up your video.
I would not attempt doing any upscaling with it as that is why you are using Topaz in the 1st place, to upscale with the best possible results you can get.

use Dione with Dehalo

Dehalo causes blur , that is why i hate using it.

Akila, if Topaz AI can’t handle a video that has obvious interlace effect, people would say it is Topaz Video AI’s problem. I am doing a favor to Topaz to report the problem and I hope Topaz will take the opportunity to improve your products.

I can send you some sample videos to look at if it is helpful.

If you look at the photos I uploaded here, Topaz Video AI made the video worse, not better. The right one is the output file after Topaz processed it.

I don’t think there is a problem here but rather misunderstanding the order of doing things.
your left picture indicates that your original video is interlaced…and you are either using the wrong model or your video was converted to progressive without deinterlacing it in the past.

could you use MediaInfo on your original video and post the results?
like my example below.


you didn’t understand why Dehalo is needed - it’s just the same for such cases - it corrects errors

try - process twice

  1. Interlaced Progressive Dione Dehalo
  2. then Iris - interlacing

it makes no sense what you are saying.
Why deinterlace (step 2) if it’s already progressive? it would cause frame jumps and stutter

Also, Interlace progressive is only to be used on Progressive videos that was incorrectly deinterlaced in the past…


Let’s wait for @james-4065 MediaInfo information he will provide us with, then we will be much smarter on the next step.
We are doing to many guessing and we might be shooting at the wrong direction.

just try

try to process the progressive video file twice
1080p 23.976fps

Deinterlacing footage and upscale to HD - using the Iris-manual - all filters set to 0


upload this file to Topaz
and use Chronos fast up to 60fps with sensitivity 1.

mr @AiDon why did you delete my comment?

Because personal attacks are not allowed. I didn’t delete your comment just edited out your comment aimed at the member.

Other comments such as about ‘hired “managers”’ will also be deleted.

It is totally unnecessary to post sarcastic or personal attack comments on this forum as people come here for help.

My advice to you is that you either help or refrain from posting. This is based on your prior warning and complaints about you from other users on this forum.
