ADVC color flickering

[2Bdecided]

There is another issue with RGB SCART that can cause this. Almost all European TVs will happily play NTSC (525/60) standard signals via RGB SCART, but many will display them only in black and white (or sometimes with weird colours) via other connections. If you accidentally author an "NTSC" DVD (525/60) instead of a "PAL" one (625/50), you'll see this problem.

Finally i solved the color flickering ! i have found where is the problem..
In the capture card's control software,i have to set the sharpness to 1 point(because on any other point its making some interference in the video which i can't see on computer,but when im burning the video to dvd i can see it on TV ) . I found this out accidentaly..:) so now i can play my dvd's on any tv and dvd player..finally !!

Unfortunately I don't know much about SCART since we don't use it in the US... However, some other users have remarked that...

1. Not all devices output Y/C separated (S-Video), even if the SCART adapter may have an S-Video connector.
2. Better SCART adapters are Input/Output switchable. I don't know how this changes the internal connections, but apparently it can make a difference.

This is something really strange: now i changed to Scart-Svideo adapter..and the colors are really bad ! The VHS tapes are black and white on the computer or sometimes there's a color,but its really bad ! its interresting when im in the VCR settings menu,the background colors are ok,but from VHS tapes its really bad or just Black&White.. this is really strange,i have no clue why is this ! do you have any idea ??

I think with the adjustment on ADVC is OK,i tryed to capture some video from analogue video camera and DVD players analogue output and the picture was OK,there was no flickering !!
I think the VCR gives " too much color " comparing to other videos..sometimes the faces look soo red,like after sunburn..i cant change anything on VCR,color or brightness..
I will try with DVD+VCR combo player these day,will see if it will be different..

Strange... the only thing I can think of is that the one of the adjustments on the ADVC1394 analog input is making the video level too high ("hot").

OK thanks,than i will change it to Svideo,will see if it will help..
No i didnt change anything in the original footage !
Adobe Premier 6.5 for compressing..im using it for almost 2 years and never had any problems with it..(i was compressing the video from DV camcorder) .

S-Video gives a much better signal quality than Composite, so yes, the image should look better.

However, I think the problem with flickering is not related to the input signal type.

In the original captured footage, did you adjust the brightness or anything like that?

What program did you use to compress to MPEG to create the DVD?

Yes it play apsolutely OK on computer !!
And how can i change if its possible the video level ??

Now im connecting the VCR : Scart adapter -- composite video cable -- S-video plug (to capture card )
Will i get a better picture if i will change the Scart adapter to another one which has an S-video output, so i can connect directly with S-video cable to the capture card ??
Like the one on this picture :

( Now im using the same scart adapter,but without this S-video output )

The connection type shouldn't matter. The video levels, however, can.

For standard video (YPbPr), the full range of levels is not supported. This is why sometimes you will see video that makes the TV picture "roll" and lose sync, especially on saturated colors and white.

In RGB mode, your display either supports the full range of values, or the input is being clamped.

Does the DVD play OK on a computer player?

Does it make some effect on this " color flickering" that on my VHS player i dont have an S-video output, just Scart , and my ADVC 1394 card has just S-video in , so im connecting the video with the capture card :

Scart -- composite video cable -- s-video plug

this can be the problem ??

What does it mean " broadcast safe colors " ? you mean the video material on dvd or the VHS player doesnt give good colors ? what can be the solution for this ?
It flickers on color surfaces for example on orange,blue,red..
I can upload a sample of video so you can see what im talking about..?

[GrassValley_BH]

It could be that the video does not have broadcast (television) safe colors.

Does it flicker mostly when there is bright white or dark blacks?

Why is this that every DVD movie and my videos which i recorded to Dvd from DV camcorder are working in both RGB and YUV colors , and the videos which i recorded from VHS to Dvd are not working in YUV just in RGB ???
what can be the solution,where is the problem ??
Today i checked with different TV's and Dvd players..
The VHS videos on Dvd are working on every TV ,just if i set the TV to RGB video input..
I tryed with one Dvd player which has just S-video output ( doesnt have the choice of changing the colors to RGB or YUV ) and none of the TV's wants to play it normally ( the colors are flickering )..

I checked Premier is using the " ITU-R Rec. 624-4 system B,G " for colors..i have no idea what is this..:)

DVD MPEG-2 is YCbCr colorspace, not RGB.
