1 Min of Capture = 1 gig AVI....????

[lrosado]

I have an AverDVD Ezmaker capture card using Dazzle DVD Complete software. Now I've read the usually 18mins of capture will equal about 4gig AVI. I end up with an 18gig (1min=1gig) AVI. Why is this? Am I doing something wrong or is it the card?

you should select a codec. your probably capturnign to an uncompressed avi. which is just a waste of time.

[andkiich]

If your file is that large, then your audio and video AVI are uncompressed. If you want to use some type of compression, then use one that is lossless. Look at some other posts and you'll be able to find the ones that are lossless.

I've found that I get better results with the uncompressed AVI, but depending on your machine and your needs, your results may vary.

[housepig]

depending on your capture software and your configuration, you need to select what kind of compression you want to use.

uncompressed avi is as good as it gets (it's uncompressed, so you're not losing any data) but yeah, it's big. Huffyuv codec is about a 2:1 compression, so it's about 450Mb per minute (about 26Gb per hour).

DV codec is smaller, about 13-14Gb per hour.

I've got that same card, I capture to Huffyuv avi, then use TMPGenc to encode to dvd mpeg. I don't capture direct to mpeg unless it's material where maximum quality is not an issue, because I find that going straight to mpeg with this card lacks sharpness and definition over capturing to avi.

I use iuVCR to capture, but VirtualVCR is pretty good as well. Don't know about the Dazzle software, but from everything I've heard it's not too good, so you might want to try some other applications.

Welcome to the capture world!
1min=1Gig is nothing. I capture uncompressed avi 1min=2Gig full res.
Only way to get image closest to original quality. Takes unbelieveable
amount of time. If you wanna be god in making DVDs better start early,
very early.)) heh

god what a waste of time. once again you dont need 2 GB for 1 minute. uncompressed avi is like 65000 kbs. dvd maxes at 10 point somethign cbr and 15 gb max with vbr or somethign like that but they never almost never encode the whole movie at 9.8 MB per second. just use huffy lossless codec. or if you wanna capture a dvd just get a dvd rom drive. you must have a huge hard drive to use that much space, then cough up some cash and buy a dvd-rom. oh and im not so sure about this next line, but if your captureing from tv, well at full reseloution, then thats stupid cause when you watch a dvd on TV it doesnt display it as 720*480, but it converts the pic to analoge. oh and if your capturing directly from the dvd player i also heard this that svideo can only handle 352*480 so the rest i dont know. so i guess

No. That's just unreal and bloated beyond necessity.

Oh yeah?

I tried to use this huffy codec. It sux badly. After 1h or spontanious time
it makes some frames crap. It'd work perfect but destroys image!
I tried it on different comps and OS. It happens only in 740x480.
Then if you take any Mpeg2 capture soft f.ex. WinDVR it will deinterlace
and alter original image. The simplest way - capture uncompressed.
All codecs have bugs and flaws so u minimize risk. Problem is the space.
I have 4 80Gb stripped array system so I dont worry.At work 2x250GB WD
heh. I know It takes time but I have just TV tuner and have not seen
good hardware encoder - all good 1s are super expensive and won't capure protected material.
I know all what mr Cecilio said so I know what I'm talking about.
Just try to make DVD with the same quality as from the store.
You will find out your hardware is weak and quality sux unless you
go with the hard way.

what so your saying you can get better quality than me well ok i suppose. and your NEVER GONNA GET DVD QUALITY AS FROM THE STORE. because if your capturing from satellite, that is not the same reselution as a dvd its lower. if you capture from cable thats not dvd thats lower. oh and just so you know 740*480 is not a standard reselution wtf is that. cause ill tell you thats not DVD. oh and my hardware is not weak and my quality doesnt suck. i cant bet you anything you will never beat me in quality. maybe alot of people in this website can, but i doubt you will.

[txpharoah]

Oh yeah?.

Do what you want.

Just realize while you are capturing over your source, squeezing only a movie or so onto your entire system worth of drives, I'm capturing high-quality MPEG2 (using ATI proprietary software), and can capture dozens and dozens of movies to my HD, and then reburn as I find time or see fit. The 352x480 4.0 MB/s MPEG2 captures look perfect. If capturing from satellite, I use 720x480 (as DTV is 544x480). There's nothing inferior about my systems. My specs are in my profile.

Again, it's your system. Do what you want.

[Ufit]

Just to add few comments. Comparing material captured by Mpeg2 soft
and that compressed from avi-uncompressed to Mpeg2 quality of avi-mpg
is 30-40% better. Maybe you don't see it on TV but on monitor u do.
Try to see a text in your movies - if its perfect shape you have a good capture.
I can capture TV with results of original looseles quality.
Maybe something wrong with my system but huffy codec fails here.
P43.06 1.5GbDDR400 XP-Pro. DVD quality is always 720x480.
All VOBS are that size (NTSC).
I need cheaper and better that current ones Mpeg2 encoder.
Dont wanna spend a downpayment for a car, do ya?
Just show some pics of your caps and then brag.

[monoxide77]

We know this, but you stated "740 x 480" instead of 720 x 480.

I too did not have luck with the huffy codec, and the pic video mjpeg codec was just horrendous. That's why I've decided to go the DV route. I capture everything great with my Canopus ADVC-100 except some animation (colors like red and blue bleed together).

I'm definitely not going to capture uncomressed AVIs. Maybe in the future when we have 200Ghz CPUs and 500 Terrabyte hard drives, this might be fast and convenient. Until then I'll stick with the ease and quality of DV.

The more you post, the more you demonstrate your total lack of understanding of digital video.

Software has come to a point where sometimes hardware is not needed. The ATI cards are hardware-assisted MPEG encoding, not pure software. If it were pure software, you'd be able to use it on other cards. The quality of output is excellent. No matter how you capture VHS source, it will always look like crap on a computer monitor. The source is only ~325x220 or so (in digital terms).

[xsbs52x]

just wondering....is there a difference between huffyuv and huffy? or is huffy just short for huffyuv? i cant find huffy in the tools section but huffyuv is there.

[Champion_R]

Huffy is short for Huffyuv

I didn't realize that DTV (I'll assume you mean DirecTv) and not Digital TV or HDTV?

Dishnetwork seems to be using 544 by 480 and 640 by 480 resolutions depending on the channel and the content. DVB Format.

Since both seem to be using at least 544 by 480 wouldn't it make more sense to use a higher resolution rather than a lower resolution to capture??

Cheers

Yes. Given your source, 720x480 is the smartest. 704x480 if you can, but that's a bit tougher to work with on some systems and with lots of software. The lowest DVB signal is 480x480, and the highest is 704x480 (in widespread use at least).
