Video Colorizer stuck in loop of downloading & deleting models

3dDee2172325

Hello, I just bought Video Colorizer yesterday after trying out the trial version. On installing the full version, I colorized a few video clips with good results. But, looking forward to having more time to do some colorizing today, I was surprised to find that the software no longer works.

I get as far as the Generate function and selecting a colorization palette, but when I click to start the conversion, it only gets about 1% in, then stops and goes into ‘downloading models’. After it downloads the models, it DELETES them! Then, upon trying again to do the conversion, it downloads the models and deletes them again. It’s a never-ending loop of downloading and deleting the models every time I try to run the conversion.

I tried uninstalling the program and reinstalling it, but still the same problem. I tried setting the downloaded models folder to read-only in the hopes that would stop them getting deleted. It did stop them being deleted, but then when I tried running the conversion again, I got a ‘Task Failed’ error message: ‘AI Conversion failed’.

I am not happy about having paid for software that only works once. How can I get this app to work properly again like it did on the first day, please? Thanks.

Please manually delete the folder located at C:/Users/DM/AppData/Roaming/UniFabAI/UniFab/AImode, then try again. If the problem persists, please let us know.

Hi, thanks for the reply. I had already done that, with no luck. I’ve replied to you further via a Ticket, so won’t repeat it all here at the moment, but will update this thread if we get it resolved via the ticket. Thanks.

Just updating this in case anyone else reads this thread, to say that the ticket hasn’t been resolved but that I found that in the GPU settings panel, under A/V Codec, there are two choices, ‘Enable CUDA/IQS/AMD Hardware acceleration’ and ‘Using software for encoding and decoding’. ‘Enable CUDA’ etc was on by default. I changed it to ‘Using software’ etc, and now it works! Very strange, since it worked the first day I had the app (but then stopped working after that).

I would like to be able to use hardware acceleration again like it was doing on the first day I had it, but until that is fixed, at least if anyone else is having the same problem, it’s a workaround for now.

The models are linked to the logged-in account. Please ensure you are logged into the correct account when downloading models. For complex conversions, we still recommend using hardware acceleration. If you encounter any issues with hardware acceleration, please report them to us promptly so we can initiate an investigation and work to resolve the problem.

Hi, thanks for the reply. I am logged into the correct account, I don’t have another account with yourselves, just one.

I already reported the sudden loss of ability to use hardware acceleration in the ticket I mentioned above and they have been looking into it but it has not been resolved. They say it might be fixed in a future update and to do a clean uninstall/reinstall at that time.

I hope it’s fixed soon, I like the app and it still gives good results with software encoding but would like to have it back to its full potential with hardware acceleration again.

OK, the ticket I filed just got closed, with no resolution. Can somebody please explain what the issue is with being ‘logged in with the correct account’ mentioned above, or else it prevents using hardware acceleration and the models will keep getting deleted and re-downloaded? It makes no sense to me. I am always logged in with the correct account.

Some feedback:
The one problem I have with the Colorizer is that it does a great job colorizing the scene that the frame used for Capture and Generate was taken from, but before and after that, the colorization is poor quality, with degraded colours and grey blotches all over people’s skin. Will this be improved in an update soon?

I see there is no documentation/manual for this app, only for the other apps in the UniFab suite. Will documentation be uploaded soon? That might help in understanding how the Colorizer works, because I had expected it to colorize the whole video evenly (like my DeOldify-based app does), not just one scene from one angle. Is this app meant for just colorizing a few seconds at a time, not a whole video? A manual would be helpful for clarifying that.

Thanks!

3dDee2172325 correct account login means that after deleting the AI model and re-downloading it, the AI features must be operated while logged into a registered account. Performing these operations without being logged in will result in failure.

As we are unable to connect via TeamViewer, our technical team cannot quickly diagnose the issue. We appreciate your understanding.

Regarding the Colorizer, the current colorization process applies to a single scene, which may cause some imperfections, particularly in skin tone rendering. Our technical team is actively working on multi-scene colorization, which significantly improves the overall video color quality. This enhancement will be included in upcoming colorization updates.

Hi, thanks for the quick reply!

Well, I was just about to send you a screenshot of my License Status screen showing my correct login name, when I had an idea:

I went into the Authorize screen, and signed in again. I then went into the GPU settings screen, changed the GPU encoding back to Enable CUDA etc Hardware Acceleration, and tried running a quick colorization test to see what would happen. And - IT WORKED! No deleting & re-downloading models! So it may be a bug in which the user has to re-Authorize the app every time they use it? That looks like it’s likely the answer to why the app worked the first day I used it but not since!

So - I don’t mind having to sign in every time, if that will make the models and hardware acceleration work. It would be convenient not to sign in each time, but it’s not a huge problem.

Ah, thank you, it’s useful to know the colorization does only apply to a single scene. The results it does get in a single scene are really nice and colourful, much better than DeOldify tech which I’ve been using for a few years now - it was very good for what it was at the time, but was never updated. And it’s great to hear that you’re working on multi-scene colorization, I really look forward to that.

Thanks again for your help, have a great day!

ETA: I decided to try shutting my PC down, starting it up again, and running the Colorizer WITHOUT signing in this time, And it still worked OK, didn’t delete/download the models. Maybe the problem was some weird one-off glitch that fixed itself by re-authenticating the app? I hope it will continue to work again now.

3dDee2172325 We are so glad to know it works again.

Thank you for your update and any problem please don’t hesite to contact us.

Just came back to say the app is still working as intended, no more signing-in needed and no more deleting/re-downloading models, so you can move this to the Solved section if you want. So in case anyone else experiences the same problem, they will know what to try.
