Video encoding question...
 

So, here I am trying to rip video from my camera DV source in Pinnacle Plus 9. I'm capturing at full DV quality and the preview looks great. However, once it's finished recording, and I go to edit what I've recorded, there are distinct horizontal lines visible throughout the recording. The quality is MUCH lower then what the preview shows.

I've tried encoding in MPEG and the lines are not there, however in high movement there's a lot of blurring and things are just not right.

Needless to say, the finished encoded product from either recording leaves a lot to be desired against what shows in the preview window while it's recording.

Anyone know what may cause this or how I may solve it?

Computer specs are as follows:

P4 2.4C running at 800 MHz FSB overclocked to 3.14 GHz.
1 gig 400 MHz DDR RAM running dual channel at 800 MHz FSB
S-ATA drives so recording speed is easily met
ATI Radeon 9800 Pro 128 meg video card

Any help/assistance is appreciated.

tough one... try capturing a different tape and see if still does it... could be the cables, the tape... not sure

I thought it might be the media I was using (I was unsure about the tapes I'd bought) so I tried some from Sony, some from Fuji and got the same result from each. I'm going to try a new firewire cable. I've tried different video cards already and that didn't help, I've reseated the RAM, re-seated the CPU, re-clocked the CPU to normal speed. Frustrating!

try capturing from a different camera... maybe the heads are messed up... or re-install pinnacle

are you sure there are no effects added to the clip? check the preferences, set everything to default and see if works

That's weird, you should be capping progressive frames but that sounds like some sort of interlacing issue.

Have you frozen the 'blurred' frames with faster motion and looked for 'combing' on the moving parts?

Unfortunately I don't have another DV source available to me at this time. I'd suspect if that were it the preview wouldn't look as sharp as it does. I have however reinstalled Pinnacle. I'm about ready to try Premier.

There's no preferences set, basically on full DV quality there's nothing you can set, it's rather lame, but at least there's nothing to break ;)

Pardon my ignorance, combing? *confused*

are you running any other programs while editing?

take a screencap and post it so we can see exactly what you are looking at... it could help.

I ctrl-alt-deleted and killed every process other then Pinnacle and Windows Explorer. That was one of the first things I thought it might be. The system never gets over 10% CPU and 40% memory usage while recording (Unless doing MPEG recording). I'm about to try another firewire cable now.

They unfortunately come up black. :1orglaugh

kinda strange....i have the same problem with some snowboarding videos we made last weekend. What I am wondering is if it has to do with the image stabilization software/feature that comes with most cameras (mine = sony handycam dcr hc30).

that stuff seems to f**k up fast movements.

Skinny lines that look like a comb that trail the moving part :winkwink:

If you use Virtual Dub for capping video this should help:

It might not all apply to your set up but it has a pretty good explanation of interlacing.

Combing sounds exactly like what I get in the MPEG recording. I think I'll sit down and read this article, it may not apply but it should give me some direction. Thanks.

I recorded 2 seconds in AVI that seems to fit with the combing problem as described, here's the clip:

Clicky clicky

Can anyone verify if that is combing or not?

nothing there ... maybe its your player

oh... and 'id hit it'

You can take screencaptures if you turn off video accelleration in media player.

clip looks fine to me

try it in premiere and see if it is still there, then you will know if it is a software or hardware issue

Yea - I agree. Nothing weird looking about that to me.

C00D11D1: Cannot play the file
Windows Media Player cannot play the file because there might be a problem with the sound or video device, such as a sound or video card.

Your sound or video device might require an updated driver. To determine if an updated driver is available, see the Windows Update page at the Windows Update Web page at the Microsoft Web site, or see the sound or video device manufacturer's Web site.

Error ID = 0xC00D11D1, Condition ID = 0x00000000


Hmm, I think my Windows hates me.

Strange, there's very visible lines around her arms when she moves them on at least 3 of our computers (Too lazy to boot more since they've all shown the lines so far). Very odd.

is your media player downloaded or bought? re-install it and try again

I just viewed it in ATI's File Player and it looks crisp, oi, I think I want to throw this thing out the window now. OK, time to troubleshoot the proper problem now.

Thank you guys so much!

I don't really see that on my player Jact - looks smooth to me here. Strange huh???

I don't think I've mentioned lately, I hate video!!! :)

There is a problem...

When she moves, you start seeing lines ...

Surfer jerking off will probably not notice, but we are proffessionnals, aren't we ????

Its is a combing or interlace problem....

Try a different software ( Vegas, Tmpeg,... ) to see with different factory settings...

Good luck.

that's normal

Jact - if your going to downsize that vid to the standard 320x240 - nobody will notice for sure.

Now that I've inspected a little closer - I do see some very faint horiz lines around her arms when she moves them but it doesn't bother me too bad. I took a look at some of my raw avi's that I've captured and I see the same thing in mine. I use Vegas 4 for my editing. I only see it in high-contrast areas or when something moves very fast. I never thought this was odd and my vids turn out great.

You might want to go ahead and encode some of that footage for the internet and see what the final product looks like instead of looking at the raw avi files.

Also, what program are you using to encode with?

yes all that is normal for interlaced, progressive no

I've encoded some of it to final and what I've tested so far looks far worse as a finished then even these little lines. I don't unfortunately have any of my tests left, I'm goign to try encoding something later and messing with settings til something works.

I'm doing my encoding in Cleaner XL.

It's called "Flicker" and it's due to that white wall behind her. I don't user Pinnacle, but in Premeire you can turn Flicker Removal on, under Field Options.

So I would guess try to find something similar under your field options/settings on your program.

:2 cents:

Bump

Jezus I am glad I am not encoding :) The only thing I understood was the "bump" lol

The best time to get rid of interlacing is during capture. I have a card that removes it in hardware but there's some quite sophisticated software de-interlacing available for capping with VirtualDub.

If you don't need a pile of video captures I'd just leave the de-interlacing through editing (Most editors seem to suck at this... (premiere...for instance)) then take care of it in Cleaner. Just make sure you select the right input profile before encoding (very important!!).
