Hi There, I am here, so sorry if I am missing any further discussion, but I am looking to upscale some old dvds to 1080p. I know there are multiple steps such as de interlacing, de telecine, and then using VEAI for the upscale. I was curious of what order, settings and models everyone uses. Than…

hi, for me the order is: deinterlacing (in this or that way, with this or that software, keeping the same definition of the video and exporting in avi or ffv1 to keep the quality) one pass with proteus v4 in 1280x 720. This is just my opinion, but I think that for a dvd quality that is low …

I found this to work well in many cases… [image] Late 80's early 90's hi8 video upscale General I’ll tell you what works pretty well for my Video8 files. it is not perfect, but plausible results and it retains the original look and feel of the video with not much destruct…

I went to your old post, you use hybrid all at 0% with dehalo -100 if I read correctly, I had tried it I think with nyx, but I don’t remember the test with dehalo -100, it was a while ago and it’s been a while since I put my videos aside, I’m devoting myself a little to drawing at the moment, I’ll t…

First stage is to identify whether the original source was analog or digital. If analog, there will be a few extra techniques that should be used, prior to any deinterlace or inverse telecine. Such as dot-crawl removal (FFmpeg’s dedot filter is good for this). You will often see dot-crawl on anal…

I just tried your suggestion using hqdn3d in Hybrid for denoising with the default values in Hybrid , on my HQ video I have (1080p) but with low-moderate noise due to low light conditions and it kills a decent amount of details from the video and makes it more blurry compared to Nyx and Iris. and it…

thanks for these details, for my part, these are sd videos from 8 mm hi8 and digital 8 cassettes, 720 x 576 pal sd 25/50 fps. I started with neat video, it is efficient but I quickly forgot, it destroys a lot of details, impossible to keep all the original details, I am really picky about quality, q…

@Akila hqdn3d really comes into its own when trying to remove temporal noise (ie between frames - caused by video tapes and tape heads). If you are trying to clean up an analog digitization, it is a useful filter - and like any noise reduction technique… “less is more”. But as you say, there are b…

I am embarrassed to say but, what is temporal noise, spatial noise, chroma, lima, etc… :face_with_spiral_eyes: :flushed: I just know noise as being noise :thinking: :no_mouth: I got noise from my Video8 tapes that looks like thin scratched at some areas and noise dots. does that makes sense in th…

Temporal noise is the noise visible on movements, when using a temporal denoiser, we analyze the frames before and the frames after, temporal denoising is more visible than spatial denoising because it reduces artifacts more than spatial denoising, but on movements, it loses details, like for exampl…

But @ssbroly had much more research time spent on 80s, 90s videos to the level he could had released and published an academic theses or a research paper, so you might find his method works better for you. for me personally his method involves more steps and tools and I am to lazy
