Hello world,
I hope I am not offending anyone by posting a request here, seemed like the most appropriate place for my humble question...
I have a bunch of video files captured from HI8 cassettes (dating back to '85-'95) using a sony Digital8 camcorder ; some parts of the capture went well, others didnt, displaying a very ugly black banding/lining as displayed on the below screen capture :
Do you guys have any idea as to what could have been the cause? Cassette age, dirty camcorder head? And does anyone know of a filter or a technique that could help me clean up the image?
Thank you so much for your time, those are childhood shots and I wish to keep them in a safe place so one day I'll be able to pass them on to my kids, if that happens... 
Bless... |

To remove the black banding around the image you can use the built-in resize filter.
In VirtualDub : first open one of your recorded video-files. Then click
> Video > Filters... > Add... : Select the "resize" + OK.
Via clicking once on the filters' name and clicking
> the Cropping... button you can now indicate the parts that may be cut off (left, right, top and bottom)
> the Configure... button you can (re)set the values of the original size (you can find these values via File > File information...)
(at preference choose New size = Absolute / Aspect ratio = Disabled / Filtermode = Lanczos3 / Interlace = unchecked / Do not letterbox or crop / Do not adjust)
I suppose you know that in VirtualDub
> the left 'Input' pane shows you a preview of the 'original' video and
> the right 'Output' pane shows you the 'result after filters have been applied'
To remove the black spots or dots, myself I do not know which filter should be best applied.
I can only give you a hyperlink to a list filters that you can try out (especially the 'denoising' ones):
> http://www.infognition.com/VirtualDubFilte...s/detailed.html
or maybe this specific spot remover:

There also seems to be a kind of 'ghosting' in the image.
Between the denoising filters, there are a few for "de-ghosting".
I leave your question open to other people for some extra advise...
Regards. |
