I wanna upload a video to youtube, it is 110mb, and max upload size is 100mb...

I am not an expert on this - I just play around with the apps to find the right option.

What could be worth doing is downloading an app called DVDShrink - with that, you can put in a DVD (they are around 4.7GB in size) and tell it what file size you want to end up with - I have shrinked DVDs to CD (650MB) size without that much quality loss.

It is quite likely the same app - or another one they do - will do a similar thing with MPEG files (assuming it is an .mpg?) - AVIs are less common for manipulation but still doable I think.

Oh - the nice thing is that DVDShrink is freeware

so nothing wasted if it doesn't work

convert it to Xvid AVI format (most comon used format on the net) if you say you can't play it (like UHM did) then you need codecs.
you can get codecs off the net easily.

to convert it Hinton use a program called "Virtual DUb"

if you need more info pm me (u might understand)

youtube is a great idea but converting some files to 100M is aksing for a degraded picture.

ive done 4 of my daughters boyfriends college dvd's. converted them to xvid and rescaled them to 100M.

if you cannot manage it. then we can sort it either of these ways: -

if you have a space where you can put 110M for me to download from, upload it, send me the link. ill convert & compress it for you then ill upload it back.

if you don't have a space, you can either split it in winrar and send them individually or look for one of those places on the net that will let you send large files for free.

so in converting from mpeg to xvid avi it take less space?

like a jpeg takes less space than a bitmap?

Its only for some footage i shot using my digi camera, on days out, such as the festivals!

exactly.
however, you must know what to set and how to play about with it. there are many proggies that will do this but virtual dub is an extremely popular one.

using Shrink will never work because it is actually called "DVD shrink"
you would have to convert the mpeg to dvd and then shrink it from that.

again, if you need converting programs etc, i have a lot of them so i knwo what to advise.

sorry Hoovie but i 100% disagree with you here. if you shrink a dvd to less than 80% of it's original quality it becomes lossy. the only reason you would never have seen this is if you have a small television or a standard one.

if you wish to shrink a dvd then use it to remove the menu's by the "reauthor" function. remove the foreign languages etc and then look back at the film.
if it is still too small, extract just the film on it's own and then compress that.
if you really intend to get the 4.35G dvd to under 700Mb then convert it from dvd to xvid avi. that will come out at about 700 and be far better quality then shrinking a dvd file to 650Mb

i have been doing this for years so i have a fair amount of experience with it.

Right, i downloaded virtual DUb...

hit another problem... my camera records as a .MOV file, whic isn't regonised!

Rich-Ando · Post by **Rich-Ando** » Sun Sep 23, 2007 1:29 pm

nuts, i didnt know you were talking about a camera file. they are mpeg4.

are you talking about a digital video camera or a digital camera that you have used to record a video?

you can get virtual dub to do mpeg4 but you need certain plugins. it's actually easier to use a different program to convert them from mpeg 4.

let me know and ill try to dig out what i have on that info.

i know a hell of a lot about dvd files etc but it's very little i do with camera files and i do remember coming accross this before.

it is posible so dont worry.

if it is a digital camera, what program do you use to put it to your pc? if you sue something as simple as adobe premier you can plug your camera into the 1394 port and import your video to there. then save it in any format you want, or edit it as you wish.

ImTOO MOV Converter v3.1 will also convert it although you may need to spend some time to understand the functions.

its a digital camera, used to take video...

The files are .MOV which i think is an apple format??

I just plug my camera in the usb, and it comes up as a removable disc drive, which i copy the files across as .JPG for pictures, and .MOV for video.

I then view uing either Ifanview or windows media player

i have been doing this for years so i have a fair amount of experience with it.

And I have very little experience of movie compression, so I will believe what you are saying

The DVD I shrunk I later watched on my PC - 17" widescreen - so I would not see bad artifacts compared to a decent movie watching experience

And you know what? I just looked in the folder where the DVDs I shrunk were ... they are each 4.7GB so I never actually watched the Shrunk ones at all

no wonder I thought the video quality was ok

OK - just ignore all my suggestions on movie compression as I clearly haven't got a clue

DVD Shrink IS a nice app to copy DVDs onto your Hard Drive though, I can confirm that bit

shrink wont handle the new encryption so don't expect it to do everything.
it was a good tool but there are others out there now
