Analogue Capture Guide v4
The new version of the analogue capture guide is finally ready! This time a lot of stuff is added and rewritten. The guide can be found here:
http://www.doom9.org/index.html?/capture/start.html A compiled chm file (4.2 MB) can be found here: http://www.wilbertdijkhof.com/ACG41.zip mirror: http://www.stefanstrobl.at/doom9/ACG41.zip If you want to print it, you can hide the search tab. __________ I remember Doom9 once said: "a good guide is written in one day", I can tell you it was a *very* long day for us The changelog is very large. A small summary * There's a new introductory section about analogue video. * There is a section on how to determine the active capture window and how to use that for resizing. * The resizing section is splitted up in a part for newbies and for advanced users. The latter includes information about sampling, Nyquist and quality of the scalers of various capture cards. * The VirtualDub postprocessing section has been completed (deinterlacing, color adjustment, etc.). * Instructions how to remove clicks and scratches have been added. * and a lot more ... This version is written by trevlac, arachnotron, i4004 and me. So, I want to thank them for their help, patience and interesting discussions we had. I certainly learned a lot from that. I hope you will like it, and learn from it. If you want to ask things, discuss things or simply give your opinion, please feel free to do that in this thread. edit: for anyone who wonders why the link to section 17 VDub frameserving doesn't work (in start.html). The link is not correct: http://www.doom9.org/capture/Frameserving.html should be http://www.doom9.org/capture/frameserving.html edit: I replaced the link to version 4.1.

Thanks for the extensive guide and the thorough analysis! A silly question, how can i print the whole guide (all the html pages) or at least, any chance for a pdf or doc file?

Hi Wilbert,
I just noticed that in section 6.3 http://www.doom9.org/capture/images/...ture_stats.jpg seems to be missing. |

I think he means de-spot has other uses too besides desratching
But this guide was never intended to be an exhaustive guide to all the options of all filters available. It is merely a guide to get people started with common filtering tasks associated with analogue sources. |

I think it is not very frequent, however quite Quote:
I can post my more detail article analisys here. 1. There are no one picture which shows as filter works O.K.: Pic.1 shows first source frame (vhs-source1line.jpg) with long horizontal drop-out, Pic.2 shows second source frame with more short long horizontal drop-out, Pic.3 shows as DeSpot successfully detect (mark) drop-line of first frame. Pic.4 shows as DeSpot successfully detect (mark) drop-line of second frame. Before Pic.5 there are text: Quote:
Pic.6 show man without buttons (false cleaning). Pic.7 show man with buttons (source). It is of cource main faults of Despot. But there are many parameters in the filter, for example we may control spot size, and spot brightness (only black for example). 2. I have some e-mail conversation with I4004 today. As he say, he use old version 1.0 of Despot (now lastest is v. 3.1 with many improvements). 3. I also ask I4004, why he does not try more appropriate filter for VHS line drop-out and descratch. I have such filter, may be you know. It has a name (surprise...) DeSñratch . It can originally to detect and clean only vertical scratch. But image may be rotated before and de-rotated after. I am not sure, that it will work, but why not try ? 4. I4004 probably will try Descratch and new vesion of Despot. 5. May be some article update must be done (later). 6. I am not "fizick", but "Fizick" ! Last edited by Fizick; 4th June 2005 at 00:00. |
