What's the age and condition of the cables being used to hook everything up?

In the case of flickering video, swapping out cables can fix the issue.

[effects]

hi the cables are new.

but it can't be the cables that are the problem because a few minutes ago i changed videos, im now using a JVC one the flickering has gone but there are dips in the sound now:(
please help
thanks

Are you powering the unit with FireWire or the (optional) external power adapter?

[effects]

i am powering it with firewire, i didn't get the external adapter with the product.

[GrassValley_KH]

If you can't try a different FireWire cable and/or (powered) port, you might have to get in touch with UK support - sounds like something might be faulty.

what kind of flicker? a wrong field order horizontal flicker or a sync type vertical flicker

[THoff]

It could also be fuzzies in the overscan area. A short sample showing the symptoms would be useful in troubleshooting this,

[effects]

Yes it looks fuzzy but im quite new to this product and i really need to put some videos on to dvd for a client. Here are samples of screens shots i took from the out put recording.

It was recorded from a sharp 6 head vcr
the tape itself is in excellent quality when played in a normal VCR there are no fuzziness or flickering there.

I recorded it via a firewire which is connected to my computer. I cnnected via the 3 RCA wires from the canpous advc 55 to the vcr , with a switchable scart, which isn't the problem because i have two and i tested them both and the flickering is happening.

Samples
ITS a Indian classical Dance performance.

Here is what it should look like this is normal:

i hope its a little clear now, my problem.
please reply
thanks

[THoff]

OK, what you have there is absolutely normal.

The fuzzies you see are in the overscan area, which you cannot see on a TV. In fact, the light area on the left side of the frame in the very first picture probably doesn't display at all when you play the tape on your TV. That's the nature of analog recordings and analog TVs.

What you do about this depends on how you will use your newly recorded material. If you are going to put the video on the web, then I would crop the image to get rid of a couple of lines at the top and bottom, and a few pixels on the left and right.

If you are going to output back to tape or DVD, then I would black-fill the cropped-out area to bring the image back to standard size. It doesn't make sense to scale what is left of the image back up to its full size, as this would degrade the image and merely fill in pixels that will once again be lost to the overscan area when displayed on a TV.

hi there thanks alot for replying back, I want to output the footage to dvd. I have captured the material through Pinnicale Liquid edition 6.10.

Will i need to capture the material all over again?
the fuzziness doesn't happen all the time , it happens sometimes and at different places , e.g. the first two dances don't have it happen, then i noticed the 4th has it in the beginning and a split second it happens in the third dance.

where shall i crop, the whole material video or only at the parts where it happens?

are familiar with liquid can you possibly asists me on how do to crop or black fill?


thanks

[GrassValley_KH]

Ah, so the flicker is only happening around the edges of the video?

The pics all seem to have a double-blur on them, but I'm assuming that's just how the interlaced image is being saved out (as a still).

[THoff]

No, you don't need to recapture.

Crop four or so lines top and bottom, and a few pixels left and right. Don't resize the image following the crop, just black-fill the area at the edge.

When you play the resulting DVD on a computer, there will be a thin black frame around the video. Depending on what software ou use and how the video player is set up, you won't even notice it. When that same DVD is played on a TV, the black frame will be hidden by the overscan area.

[effects]

ok, and this will stp it from flickering :)?

[THoff]

Yes. It will cover up the area with the flickering fuzzies.

[effects]

ok i am trying that now, i'll let you know how it goes

thanks again

[effects]

hi i cropped around it but its still flickering :( when i tried it in the dvd player

see here you can see the black lines around it looking like a box, but its still flickering




am i doing something wrong?


please help
thanks

[antonsvideo]

what flickers? the centre of the video or the edges or everything?

it is hard to tell from a still what flickers because a still does not move

[effects]

i think the center flickers more.

[kbosward]

Are you able to write out just a few seconds of the video to a MPEG file and make it available for people to download and watch? That would help for us to see exactly what you mean.

[antonsvideo]

maybe the field order is incorrect

if it is upper, try lower, if it is lower, try upper

[effects]

hi thanks a lot, for suggesting that i make clip of it, i did that and watched it back and it didn't flicker :):)

when i rencode the clip and imported it back to the timeline the flickering goes away :)

so now what i need to do is find a codec so it doesn't look blurry or lost of quality. But i main problem seems like it has been solved yey!

thanks


Thanks to everyone who has helped me out here especially THoff, who pointed out that the flickering is normal. :)

sorry, flickering of any kind is not normal, please investigate further

try a TBC, a TBC should be a must for tape capture such as VHS

[effects]

hi whats a tbc?
please reply
thanks

Time Base Corrector (http://en.wikipedia.org/wiki/Time_Base_Corrector)

[effects]

im from the uk , where can i buy one, besides sorting out the jittersdoes it do the same things as the advc canopus 55?

[effects]

i really need to buy a tbc , because i just swa the playback and it jitters literally every 5 seconds and its too much for me to convert every little bit so i want to go for a tbc.

i was thinking of this one, is it any good?

[antonsvideo]

I am not familiar with the advc canopus 55 and don't know if it has a TBC inside, I have the Edius SP card (a 5k card when I bought it and it does not have a TBC and the signal jitters from analogue sources if I try to capture without TBC)

the datavideo TBC range is pretty affordable and good

[effects]

im having trouble how do i connected the tbc as well as the canopus to my video?

A time-base corrector is a video processing device, therefore the video should be passed through it, before the final destination.
