Video Enhance Ai and VHS

Hello, I just want to know what is the best A.I Model for a amateur VHS video in 720*416 resolution, I want to enhance this in 4k. Does the model Artemis LQ make good result ? I join on this topic screenshot from the original video, thank you very much. !


I would try the gaia cg first, but I can only speak for myself. I know others had good results with artemis too.

Thank for for your anwser, I will try as soon as i could

I’ve only been using this for less then a week. But most of my footage has been VHS media.

So far I haven’t had any real luck with the Artemis renders. However Gaia HQ and CG have given me best results. I prefer CG in most cases but have had a few where HQ did better. Remember you can preview a few rendered frames to view the quality.

I’ve been also trying to enhance VHS footage and have been experimenting with different settings. The results look gorgeous (I’ve used various Dione options primarily but have been testing others, as well), but I’ve consistently been experiencing an issue that I’ve seen come up as a common problem with Enhance AI in google searches - the resulting export featuring occasional skipped and repeated frames, which creates a ‘jittery’ playback effect.

Is this something others have experienced when working with VHS footage? A part of me wondered if it has to do with how Enhance AI deinterlaces.

I’ve asked Topaz support about this and they haven’t been able to pinpoint where the repeated frames issue is coming from so far.

Hi, I use Dione TV on anything interlaced and set it to 400 resolution. I render out as a series of frames at progressive de-interlaced TIF 16 bit and then import these into my Vegas Pro editor for colour correction and adding back the sound. It’s a long process and uses lots of hard drive space for a long video but the results are just awesome. I have just restored two DV tapes that were 18 years old, and have been able to take still frame ‘photos’ of the event which are so good that people who see them are convinced they were taken with a camera. Not done a VHS attempt yet, but you must use a deinterlacing preset to get the best from any interlaced footage. I have never experienced the ‘frame jitter’ problem in over 30 video projects restoring. I wonder if it is to do with the interlaced order. If it is not set correct it will cause jittering, but that would be continuous, albeit only obvious on the moving part of the image. I will try some VHS and see what happens.

Thank you for the feedback!

I’m glad you haven’t experienced that issue.

I’ve mostly been using ‘bottom first’ as the field order. Do you know which you’ve done?

Also, what file type are you going into Enhance AI as, out of curiosity? I’ve been going in there with AVIs. I’m currently trying to run them through Handbrake to deinterlace and/or detelecine and come into Enhance AI with that having been done and also with them as mp4s, but I’d rather not downgrade the quality in Handbrake before going into Enhance.

hi @tony11
I just purchased the video enhance ai software and am about to improve my 10 old VHSvideos.
Would you be willing to describe step-by-step (and settings in video enhance ai) how you were able to get great results in restoring your media?

Ive got a rtx 3080ti and currently running my first scale up with deinterlacing, Dione TV option and 400 resolution. Side-by-side comparison look great for now…!

What do you mean with " I render out as a series of frames at progressive de-interlaced TIF 16 bit" ?:slight_smile: Sorry i am a newb…

kind regards

Hi Bjorn, VHS videos are very difficult to restore to anything good, but with Topaz AI there are a lot of ways to get the best.
To start - let me say, if you have a ‘first generation’ VHS tape - that means the tape that was in the camera that shot the video, then that is the best start point. Next is a VHS that has been a copy of some other format, like 8mm or better still Hi-8 or S-VHS or DV tape. These give even better results. That is because their original video is higher detail than VHS, so the loss in making a copy is not so bad.
So - there are two things that VHS does to make the quality fit the old tape when it records. It does half the luminance detail (the black and white part of the video) and even less of the detail in the chrominance (colour part of the video). If you understand this, then it helps to work out better results.
The worst tape, which I have at the moment, is a VHS of a wedding made in 1998 which was a copy of the camera VHS tapes edited. So it has very poor quality and is a good example of how much work can be done.
The first thing is to capture the video to the computer in the best format. This is interlaced AVI usually.
Remember, in addition to the loss of detail, in older videos there is also a lot of noise in the dark part of the video, or if there is not good light on the original video. This noise can make the detail fuzzy and not easily seen.
My first question is, - do you have video edit software on your computer?
I use Vegas Pro as I used to be a Vegas beta tester when it was owned by Sony, and know how good it is for helping to restore video with Topaz Video AI. Also, let me say, that too much sharpening will ruin the picture quality of VHS restoration and make it look visually artificial and uncomfortable. You will understand that my background working for ten years at the BBC has taught me a lot, which I am trying to tell you about in a couple of emails! So, if you follow my ‘exact’’ process, then you will get the same results as I do. BUT - it does depend on having the Vegas video software to complete the best quality final video. I’ll do more information for you when I know that you have Vegas. Also, you need to do this with plenty of hard drive space. So for an hour of video, to get the best, you will need a hard drive space of nearly 3 TB spare - just for the restoration. The Vegas Pro video lets you make HEVC mp4 files of your results that look amazing and also are fast to make because they use the power of the 3080Ti to encode. I think Topaz ‘may’ include that part soon, but it does make a huge improvement in workflow with Vegas. You can also make many different formats and sizes of video with Vegas Pro in all sorts of codecs. More soon…?
