I processed 5 hours of old family video on June 9/23 using the Iris enhancement at the time and the results were more than acceptable. The video was originally 8 mm ⇾ VHS ⇾ DVD. I converted the DVDs using Handbrake. I then processed them in TVAI looking for the right settings and saved a preset. Then did a batch conversion of 5 one-hour videos using that preset. Today, using that preset, the Iris is making everyone look like monsters and the results are frankly terrible, and it’s not only the faces that are affected. Anything that has an edge is out of wack. I tried both the LQ and MQ settings, as I don’t think there were two settings for Iris back then. How can I get the Iris filter from June 9/23, so my video will look like the original conversion?
Did you enable the use of old models in preferences?
Then try IrisLQ V1.
@windspear if you have the ‘enable previous model versions’ enabled , you can try selecting the older / original Iris v1 and see if this is what you are looking for.
Yes, I just tried that and it made no difference. Thanks anyways for the suggestion.
Are you on Windows or Mac?
I’m running on Windows 11, latest build, on a 13000KF with a GTX 4070 and 96 GB of ram, and two fast 2 TB WD Black NVMe’s. So, I have no problems processing the files, and this was my original configuration from June '23.
I asked because I do have some older Iris models from Aug.2023 files as backup - but that for MacOS.
While admittedly the quality of the video I’m converting is generations old, you’d think that I would be able to reproduce the results using the saved setting and even enabling the old version 1 Iris enhancement. I was able to get a reasonable copy by using the Manual Parameters and dialing the Anti-Alias/Deblur down to -65. Although the results aren’t as good as the original from June '23 and very blurry, it at least gives me a starting point to run another filter to see if I can improve the result. I had to run the Iris Medium Quality, as the Low Quality produced unusable results. Perhaps I’ll never be able to recreate the results of those halcyon days when the Iris model was first introduced. The results back then were brilliant.
Maybe offer a video file for testing so we can find out decent settings for you?
I think the ‘Recover Details’ slider was added later. Have you tried setting that to 0?
Unfortunately, it’s not mine to share.
Just tried that. It didn’t make any difference. In a previous post, I mentioned that dialing down the Anti-Alias/Deblur gave me the best results, and that still stands.
I know your feeling, been there. Perhaps you’re offering a different resolution to input to TVAI? Are you sure your Handbrake outputs are the same pixel size?
If you’ve got the original output files from last June, grab the app “MediaInfo” and go through with a fine-toothed comb, every setting baked into the metadata.
I’m using the same Handbrake output file as before and the pixels are the same size.
Thanks. Didn’t think of that, but I copied the settings verbatim from MediaInfo, and the results were awful, so I think the original Iris1, is not the same as the Iris LQ filter the TVAI uses now. That’s the only explanation that seems reasonable to me.
I’ve definitely been here before. And thinking back, I downloaded the old version(s) of TVAI that I used then, and it worked fine. TVAI itself can change aspects of the video, unintentionally, usually as a bug. The bugs I’ve hit have happened at the introduction of a new version, like a v.0 or v.v0. I’d roll back to the previous v.2 or v.v2 (or 8 or 9, whatever you were last on).
Does MediaInfo give you the TVAI version? Anyway once you’ve started working on a big project and are liking the outputs, keep a copy of the application bundle somewhere. It’s fine to update frequently, but depending on the mission-criticality of the project, just hold off. I mean it’s bad enough that some of my processing takes days, and those days can be longer than the time between versions. (For the record I don’t mind that this is a company actively developing its product, and, it’s listening to users … that’s rare enough).
Last year I hit an equivalent to what you’re hitting, and came into this forum, posting screenshots of the “screen door” effect I was hitting. A few versions later it was fixed. But the only option for me was to roll back.
Unfortunately, MediaInfo doesn’t give you a “Writing Application” for TVAI. I only have the date I originally processed the files, which were processed on June 9, 1023. If I can find out what version of TVAI was current at that date, I could perhaps install that version temporarily. I think I will append the version number as I do in TPAI to the file to make it easier to determine which version processed the file in the future.
That sounds like what I had to do too, if I remember.
Unfortunately this doesn’t help much. As the old version of TVAI will then still download the new model files.
So, as long as you don’t have a full backup of that old version including all model files (for the models you use) you’re stuck.
