Hey everyone,

I've had my DVX-100a for awhile now, but I can never seem to get the best quality footage out of it. I'm not exactly sure how to explain the problem, but i'm posting a screen grab. Close-ups usually look OK, but wide shots seems to blend together almost. They have these weird vertical lines running through them. Not interlacing issues though. This is 60i footage.

Here ya go

If you look at the truck in the background you can see these lines right where the bed of the truck folds up and directly beneath the window. I can't seem to pinpoint what else doesn't seem right, but it seems like I could be getting such better quality footage from my DVX. Thanks!
 
Please post your scene file settings. It could be this is just the thickness setting set to THICK, but more likely this is a preview problem in your NLE. Which are you using? Maybe preview is on low quality?
 
I'm using adobe premiere pro 1.5, and this is an exported frame... the scene file settings are as follows:

Everything is set to Zero.
Gamma= Norm
Knee= Auto
Matrix=FLou
V Detail Freq= Thin
 
Those are interlacing artifacts on the top of the truck, caused by shooting 60i.

How do you figure they're not?

You can also see them on the chrome bumper of the truck, and more clearly on the shadow of the truck against the concrete.
 
Hmm...I just didn't think there would be interlacing problems if I de-interlaced...

Thanks!

But overall, does the quality to you seem a little sub-par?

That's where knowing 'how to get the best out of your cam and making it look the way you want it to in post' comes in. It just takes a little knowledge and experience.:thumbup:
 
I find Premiere enhances that even more. I used to use Premiere all the time and had that same problem but started using avid for a project and noticed all the stairstepping went away.

Dude, are you kidding?! You should have mentioned this was deinterlaced! Premiere has the absolute worst deinterlacing in the world. This is exactly the quality you'll get if you deinterlace in Premiere.

You need to shoot in 30p or 24p, those are progressive formats and you won't have to deinterlace. You'll just have top-notch full-resolution images.

i get way worse interlacing (or interlace looking) lines when shooting in 24p... why is that?

Your working in the wrong knid of timeline. If you work in a 24p timeline, you won't see the interlace lines at all, they will be removed.

okay got ya, but i thought if you shot 24p you were supose to edit in a 30 fps timeline and a 24p timeline was for video shot in 24pA
 
Ideally, yes, shoot 24pA, edit in 24p timeline. You can usually also edit 24p Standard in 24p timeline, but the quality isn't as good.

If you edit 24p in a 60i timeline, sure, you will see the interlacing, but you won't see it on a TV. It's th same as 60i. People need to understand that it usually doesn't matter if you see interlacing during editing, you won't see it on playback.
