Interlacing and getting rid of it!

[czTempe]

Hello,

Okay, so I have this kick ass Sony DV camera here, and I'm using Premiere 6 to capture. So, after I capture it, I go to open it in TMPGenc, and covnert it to DVD. That works, but it is full of INTERLACING!!! How do I get rid of this, because I don't like the look of it? It does not seem like there is any when I play back the AVI, but when I play back the DVD-compliant MPEG-2, there is.

I just read posts that say I should keep it...so what should I do then? I want to make it play on a TV DVD Player and have it look great. What settings should I use in TMPGenc?

TMPG has a deinterlace filter. Click on the setting button. A new window will pop up with different tabs. I believe it is under the video tab. I've never had to use it, so I don't know how well it works.

if you're putting it on DVD, just leave it interlaced. on your TV you won't notice them at all like you do on your computer monitor. it actually plays smoother interlaced (unless you have an HDTV and a progressive scan DVD player).

Well, what does the interlace look like on a HDTV?

[monoxide77]

i don't have one myself, but from what i've heard they are progressive scan (non-interlace) like your monitor. however i'm sure they interpret interlaced video.

So in TMPGenc, how do I need to have the settings to encode to DVD?

[monoxide77]

you can load the DVD template. from there its pretty self-explanitory.
here's a little bit of what to do:

Yeah...this isn't for a rip or anything, and I didn't use a boom, I just used the in-camera mike, so I'm not too worried about all of that, I'll just use the wizard.

Thanks everyone for your help!

hi cdTempe,

first, when you say that when you play the video back (from your dv
camer) to your TV, you say that quality looks great. Yes, it will.
Why ? ..well, because it's not compressed (to mpeg) it's still
in it's magnificant original format.

But, once your convert it, and of course, depending on how much
bitrate you give it, you will see those Interlacing artifacts.
Even at highest bitrate, you will see it !!
I've said this time and time again, that MPEG-2 does NOT do anything
to enhance or improve upon in quality. It just has support for
displaying it if one has encoded to MPEG-2 w/ Interlace.

You all seem to prove my point, that Interlace looks louzy once
encoded (and then played back on DVD player) That is true. But,
there are a few things you can do (sorry that you can't do much for
your current footage though) ok, first..

* LEARN how to hold your cam, and
* USE a tripod
* STOP using zooming
* when zooming, ONLY USE the camera's actual lens, NOT digital over xxx
* STOP panning and swaying your cam around unsteadily
* most important, is perfect your Encoding Skills !!
* and a few other things I left out in this list (should be long)

Now, in the future, and after observing the above, you should have
better final encoding quality - NOT DVD quality, but at least better.

Also, make sure you use 29.970 fps and NOTHING else, that includes
* 3:2 pulldowns
* IVTC
* or any OTHER frame rate change

You must encode your dv footage w/ only 29.970 because dv cams are
NOT telecined. DV cams don't take footage at 24 fps, so doing an IVTC
on 29.970 fps will not help here.

I think that above says it all.

Good luck next time

I didn't get a chance to see what it looks like on TV yet...the guy I got the camera from (I'm doing a project for him...pretty much NO-budget) didn't give me any cables, so I can't look at footage on a TV like that. Right now, its just getting the footage over to my PC, and then to DVD, and I'll see how it looks. There is no Interlace on the captured AVI in Premiere though, which is kind of...odd...it looks perfect.

This is my first time messing around with this on DVD, so I'll just need to experiment and see what looks good to me.

hi cdTempe,

>> There is no Interlace on the captured AVI in Premiere though, which is kind
>> of...odd...it looks perfect.

odd, ..then Premier must be doing an de-Interlace as it captures. Shame that
Premier does NOT tell you this. Some peoples may be doing ANOTHER de-Interlace
on it, in another app, like vdub or AVIsynth and thereby making it worse.

based on above, I would say "no wonder.." why peoples complain of consitant
quality loss after encoding!!

cdTempe.. But, I would double check your Interlace statement above to be sure.
If you load your AVI source into vdub, and magnify your source, you SHOULD see
each frame is Interlace, becuase the frames will look poor or distorted or
dirty.
But, if not, then perhaps Premier IS performing a de-Interlace during capture,
OR while your source displays in it's time-line (using a built-in de-Interace
behind the scenes - - perhaps w/ an auto-detect routine or something)

You never mentioned what brand/model DV CAM you are working with !!
