Störungen unterer Bildrand bei S-VHS (Capturing)

Disturbances at the lower edge of the screen S-VHS (Capturing)



Frage von andzel:
November 2006

Well, I long with all sorts of key words searched in the forum, but found nothing. So go:
1) The problem: When capturing from the S-VHS camcorder - which would otherwise properly funzt - resulting s.unteren screen interference. Looks as if the last line repeated about 10 and bottom horizontal offset (ie, moved laterally) added .. what's going on? Ah yes, the settings when capturing seemingly have no influence since drauf. No matter what I Pixelmasze RESTRICT (720x576 or 320x240 - what content is available), down "flickers" in the way that the bottom lines of horizontal offset are appended below. Ahja the "normal" (?) Flicker s.unteren edge - it's not analog S-VHS! - Appears between the "master image" and the mysterious repetition.
And in the direct output from the camcorder to the TV via S-video cable's repetition of this phenomenon but not!
2) The system: I have an old S-VHS camcorder get a gift, where OK (SABA VM 7100, hardly used, with few pockets and n Tapes ;-)) So ne cheap TV card with S-Video in Concerned (Typhoon , of Conrad - the chip is of Phillips, announces itself as "TV Card 7134"), then "Magix Video deLuxe 2005/06" as the editing software, video capture, I do via S-video cable, the sound on .. is probably no preference, right?.

Tips of all kinds are gratefully accepted ;-) Ahja nor 1: Could be that I really was simple've overlooked ... but here you do not have fear, as a "lamer" to be stamped :-))

Anzel Hello!

This is normal for analog records.
On the monitor you are all lines that also disturbed.
On TV, the picture cropped.
Your keyword is: Overscan

Antwort von andzel:

Boah .. n yes that is quick forum. Fine, fine, fine :-) OK, I will look at such "overscan", not just here. The exact relationships are still not clear to me.
For the TV-picture (which of the digitized video): I've now only n times in the editing program workaround I discovered: There is in this Magix ne "zoom" function. I think this is OK, so if I hide the disturbing edges in that I work in the copy of the framework for the final rendering as set by the disturbances remain outside ...
thx so far.





Antwort von andzel:

Yo. Seems reasonably clear. When rendering the film a little of the original input s.Rand off - the ratio remains, "meat" to the subject must stop shooting at their accounts - and "the porch is finished" (so hats my grandpa said that if what it was clear :-)) or are still better ways?



Antwort von littlesummerskjh:

Anzel Hello!

If you are clipping it is rescaled and is based on the quality.
Better is you put an 8-bit wide border around the picture.
On TV you see it and not on the PC is not the synonymous.
The MPEG2 encoder so synonymous has no problems.

Antwort von andzel:

Ok. If you're already so fast, then, now the lamer question: How do I create a border around the picture? Had times been synonymous ne kind of "mask" to think. At its 2nd Track n black frame with a transparent center or something?. Nen quick tip on hand, as the Magix Video deLuxe going? If not, is not synonymous bad, I try so synonymous around like ... man, have only been 3 days, the video equipment and - can not be said often enough - thanks slashcam.de already steep learning curve reached ne ;-)



Antwort von littlesummerskjh:

Andzel Hello!

As you kannich unfortunately synonymous not help because I do not know your program.
Synonymous, but I guess the way you think.
I work with Premiere.
Anything else. The rim should be 8 pixels by 8 without remainder divisible.
The encoder works with normal 8x8 blocks and by this way the encoder enlastest you very much. This comes back to the Quality of the image remaining benefit.

Antwort von andzel:

Yo. First Thanks for the nice dialogue. That helps. Premiere is synonymous not unknown to me, btw ;-) I'll see what I can find so s.Methoden. The original intention of my posting was to find out whether what with the camera or the cable or the - cheap - capture card or the software or my method is wrong. But now I'm thinking that the components in the context of the low-budget, to which they belong, properly fuktionieren.
Thanks at least for the suggestions and all the best .. cu here ;-)

The SABA VM 7100 is identical (technically identical) with the legendary JVC GR-S707:
+ + http://209.85.135.104/search?q=cache:la-f9tPqZIoJ:info.electronicwerkstatt.de/bereiche/fernsehtechnik/vergleich/saba.html SABA VM7100 + jvc gr-s707 + & hl = en & gl = at & ct = clnk & cd = 1
I had the JVC GR-S707 own times and yes: The image quality is a hammer, F 1.2-Optics, chroma & luminance noise filter and numerous other HQ circuitry for image detail enhancement (glaub was 1989, the best consumer device you could get, has many Prices demolished)

A MiniDV drive because you have to install, then it might be the thing to loose with a Canon XM2 record ...

Unfortunately I must inform you that the device is probably not much longer will make the following reasons:
;-( http://forum.slashcam.de/viewtopic.php?p=152888 # 152888

My wiegesagt identical JVC GR-S707 is now, unfortunately, so is buried worden.Leider stuck in their Electronics lots of these stupid capacitors. Here are some pictures of the wrong which the Japanese GR-S707 have decomposed capacitors of the same exchange:

(see bottom of the silver capsules)

Whether your problem is here synonymous already a first indication of this is hard to say, it would not exclude, however, especially if it did not so war.Meine JVC GR-S707 hate the way, (not coincidentally) is exactly the same Symthom.

An exchange (s.besten all equal) Capacitors costs of a specialist made to ensure the 500-1000 euros (high 100erten material of capacitors and especially a lot of working time), whether you need to pay off the JVC wissen.Eine qualified workshop will hardly do, but the device is just too old (and probably would be priceless)

Hope the course is your thing still makes time ...



Antwort von andzel:

Well ... this is indeed interesting times. Thanks for the tip. A pity really, but now the camera so I get a gift and the replacement battery for gabs 20EUR. To that extent would the damage in case of failure is limited. Let's see, I am going to the old part eh not too much to claim. Feature films are not rotated ;-)



Antwort von andzel:

Yo, if you have someone with a similar problem to this thread triggers the disorder at the bottom of the Picture in the digitization of S-VHS videos come from actually overscan. I remove the Magix Video de Luxe on "Effects"> "Video Objektefekte"> Image Size and Position ">>" cut ". The values for the cutout so that when one by Height 8 Partial subtracted (ie eg 552px instead of 576px). The Picture center, and ready. This gives black bars above and below, which of course are already taken into account when shooting, but the funzt.
Only if it is of interest - yes eats no bread ;-)
The camera is also OK @ Dino. I've really enjoyed so :-) The tip with the capacitors, however, was still very useful!
