Today I greatly improved the "How does it work" description of vhs-deshaker, including visualizations of what happens. You can read it here if you're interested: https://github.com/rsnitsch/vhs-desh...-deshaker-work

But yes, having been a programmer from college freshman days (1972) till gradually having to drop out roughly 20 years ago, and having started using Avisynth occasionally since about 2004 (best I can estimate), I HAVE wondered why software can't be written. I will eagerly devour the links you all have given EXCEPT for deshaker type info. (EDIT: Oops, I realize I may need to jump on the deshaker tool.) The most common problem does not need VERTICAL correction, as a decent tape in a machine with a good video head will not need that. It's the individual LINES that need it. I'm 69.5 and in middle of battling stage 4 melanoma, as well as being a very low-income senior. After the melanoma's over (and I am encouraged at the probabilities it won't be over via the grave), I may be able to devote some time and brain to programming IF I had access to knowledge. My skills in Avisynth are relatively weak. I'm about to buy a $100+ price range SD to HDMI upscaler. I doubt even those more expensive units have a TBC in them. (Don't buy $50 and under units.) Again, mainly JohnMeyer and Robert.N, thanks for bringing up this subject just a MONTH or so before I needed to jump into the fray! I want a solution BEFORE I do any serious captures. (I do have at least one VCR head to replace first.) Last edited by TCmullet; 3rd May 2023 at 03:02. |

EDIT: OOPS!!! Just after I sent the link to a local programmer friend, I happened to notice in the lower right region that "Releases, Latest" region. The joke's been on me all these years! (I'm so used to normal webpages where it's generally easy to download an application by a non-programmer.) Last edited by TCmullet; 3rd May 2023 at 04:18. |

Robert, I will be using Avisynth for everything except the direct running of vhs-shaker.exe. What are the rules for what codecs I can use when I create my input.avi? Does it have to be an AVI or can it be something else like an MP4? Am not worried about audio. I can fix all that after the video is done. I do wonder though why you're not using VFW so that I can pick an output codec in VirtualDub to read it later.

Internally vhs-deshaker relies on OpenCV's VideoCapture feature, which in turn is based on ffmpeg (among others). Therefore, vhs-deshaker supports a wide variety of input codecs/formats. As a rule of thumb: If ffmpeg can process it, then vhs-deshaker can likely open it, too.

My first test was pretty bad. Much jerking around left to right and back. After staring at it a minute, I concluded the noise bar at the bottom was about as far offset as was the sideways jumping. I concluded that I'd need to strip that off.
The sad news was that after stripping it off, the jerking was almost as bad. So there's something incompatible between your program and my videos. I have to give up on this for now. I can't think of anything else to fix it. Note: My video is not bad in need of correction. I had thought that the very slight fast jitter I see in some spots made me think this was the problem in this case. |
