Is it possible to get better video quality..........

[us_matrix]

Hi,

I have Home DVD video disc and it's about 3 hrs long and the quality is pretty poor. I was wondering if i change to higher Frame size/rate and bit rate and burn it on another DVD-R. Will i get better quality when i play it on DVD player ??? All i want is better video quality and i don't mind to put it on 2 DVD-R disc.

Orignal Home DVD-R disc:

MEPG 2
Frame size 352 x 480
Frame rate 29.7 fps
Bit rate 5000 kbps

Change to following size (I guess needs 2 DVD-R disc for 3 hrs long)
MEPG 2
Frmae size 720 x 480
Frame rate 29.7 fps
Bit rate 8000 kbps ?

Is frame size or Bit rate to bring up video quality?

Probably....search to the left.

What ever happened to "Cartwheel"

Greatest animator to ever hit this board.

upping the size and bitrate is only going to give you a bigger file that looks the same or worse.

although there are some things that can be done to improve the appearance or minimize certain problems, the general rule is "garbage in, garbage out" - you're not going to get much better than your source footage.

what exactly is bad about it? can you post a screen cap of it?

[us_matrix]

Can you be little bit more specific?
I used a search tools before i posted it. As i understood. Bit rate is the one will increase the size most. But i was wondering if i capture my original DVD disc with Higher Frame rate/size and Bit rate. Does it produce better video quality (Visually better video quality) other than sizes only???

Why capture your original dvd?just do a copy with dvdshrink or other useful progs listed on the left.

What you are proposing is not effective. You never want to re-encode something
again, that is from a lower grade.
.
.
If 352 x 480 is your source file, raising it to 720 x 480 will only result in a
poorer quality, add to that, rasing the bitrate is pointless too. If your source
is such, there is no more room for improvement in your case. If however,
you had the "original" source files ie, .avi's then things would be different.

If your 352x480 @ 5Mbps was crappy looking, chances are it's very noisy footage. Re-encoding at a higher bitrate and/or resolution won't help as the damage is already done, but it may be possible to apply noise-reduction filters before re-encoding it.

morning guys,

@ Sulik, hi.

yeah, that could done too, but the only negative I have w/ that, is that due
to the first encode that this peson may have already done, there's now the
those [ ] square macroblocks to deal w/ in the noise reduction steps
.
.
I don't know whta is ment by "home DVD video.." unless it was ment, that
the source is "home footage".. then he would only need to get hold of the
miniDV tapes (if it's home footage being talked about, unless those are no
longer available)

But, now two new things are added to the pot.. previous noise, and now the
macro-blocks (which has the noise embedted in it) to deal with. And re-encoding
is only going to make things worse or enhance the issues

Hmmm.. there should be a good link ?? here on vcdhelp for techniques in
noise reduction for those requiring assistance or want to improve their
source files (no matter where they originated from)
.
.
Doom9 has a few, and kvcd.net too. I just can't remember the links
Still, if you do a search on google (or here) on "noise reduction", perhaps
some info could be found

Thanks for all your reply and i really learn a lot from you guys

I mean Home video (our wedding video) is captured from DV. (This is what i knew from my camera man who was hired for my Wedding party)

He is really in old age (don't know much about Computer and Digital video editing) until i found out was too late. He told me that the way he captured from DV to some kind of VCR tape machine for editing. And he just know how to do editing from "VCR Tape machine", Once he finished all his editing, then transfer to PC to burn a DVD disc. I guess the reason why the quality is poor is because he captured DV source to Analog "VCR tape machine" for all his editing" I told him that i could help him capture from DV to PC directly to get better quality ( I think it will do better quality becasue it is digital > digital instead of digital > analog > digital) But he told me that there is another problem to do DV to PC directly. He used 2 DV camcorders to film certain scenes in my wedding party like one camcorder from bride side and one from groom side. When we watch the video. We see kind of like Picture in Picture (for both side) He really have no idea how to edit 2 DV Camcorders if using PC software for editing. That's why he still doing his own way (DV to VCR Tape machine for editing). Therefore, the problem is i don't know how to do eidting if i capture 2 DV source to Ulead video studio or workshop for mixing 2 video source in 1 video (Picture in Picture).

My original idea was captured Wedding video DVD-R disc to MPEG and then add motion menu and chapters. I am in progress now. Since i am doing converting VOB to MPEG 2 and have a thought of changing Frame size/rate and bit rate to improve quality. Looks like it won't work that way. "Garbage in garbage out".

well, I'll say this - grab your raw source footage from him as DV footage, that way you have everything available in the best possible quality.

as far as editing, at least if you have the raw footage, you can learn to edit - especially since you have a decent yardstick to go for (you could just duplicate all the edits he did on your original tape).

editing software abounds, from higher-end prosumer stuff like Premiere Pro or Vegas, to freeware like MovieXone, Avid Express Free or Zwei-Stein.

if this guy who filmed the footage is someone who is willing to help you out, he can give you editing theory and general tips that work on any system, analog or digital, and you can work on how to implement it on whatever editor you decide on.

You could try TMPG and use some filter's to try to clean up some bad spot's. it work's for cleanning up bad VHS capture's. Give it a shot.
