Does anyone know....

how can i compress a 3 meg dvd movie file down to 100mb so i can upload it to youtube?

Oh dear, give me 30 minutes to pick myself up off the floor and I'll try and reply.

eh? is it really difficult then?

get easy dvd shrink

i have dvd shrink 3.2 but it says it is invalid dvd navigation structure. It's a homemade dvd so i don't know what difference it makes.

Oh,I don't know then I'm afraid.  That's a big shrink you are after too, didn't see that at first.

Is your dvd made up of vob, bup and ifo files?

That looks a nifty program.  Haven't tried it though.

it looks like this in the dvd folder

Great little proggie, not sure if it handles dvd's though

ACE, if your file is 3 meg and youtube limit is 100 meg, then isn't your file falling well within the 100 meg limit anyway?

If your movie is 3 Gig, then compressing that down to 100 meg, would be nigh on impossible i would think.

If i'm teaching you to suck eggs i apologise, but 1 Gigabyte (Gig, GB) is 1024 Megabytes (Meg, MB).

TEMPEnc Author makes dvd menus so I guess it does

the file is 250,000 Kb, max upload is 100mb. how does that compute (2.5 gb?)? and yes you are teaching me to suck eggs.

it depends on your compression ration etc etc etc

but DIVX ( www.divx.com ) could be able to get it down by the 66% you want if you have recorded the video in a high enough compression otherwise you would need to start shrinking the picture size to reduce the file size

1 GIGABYTE = 1,024 MEGABYTES
1 MEGABYTE = 1,024 KILOBYTES

250,000 KILOBYTES / 1,024 = 244 MEGABYTES OR 0.24 GIGABYTE

The easiest way to understand it is if you think that 1 megabyte, MB, Meg (all 3 common names for the same thing) is 1,024 kilobyes or kb as your pc will normally show it. For ease of calculation, forget the surplus 24 of the 1,024 etc. and just divide by a 1000. Therefore 250,000 KB is 250 MB, give or a take a few (the omission of each 24 kb in the calc explains the disparity between the approx value 250mb and the actual, which is 244 mb.

cheers leehack.

My pleasure, hope it helps.

The 2 best methods to reduce a file size, but still have it clear to view are:

1 - As Ironside says, reduce the size it will show on your screen i.e. if its showing in a 400x300 pixels window, it will be much more hefty than a 200x150 window. The best way i understand this (i like to simplify things) is that if i painted 2 pictures one each at the sizes above, i would need more paint for the larger one, so therefore in computing terms it will be a bigger file.

2 - Cut the film, to only show the very important parts, it is more appealing to download and watch and is far smaller.

The best method for compressing a file is simply using a good codec and having experience.

A good video encoder is like a dog who talks...rare. ( Yes I admit it, I watched some blackadder a day or two ago :p )

All the information is out there if you have google, I recommend reading doom9s encoding guides for general reference and using x264 as your codec of choice, you will get sick sick compression if you it correctly ( 300-400meg file per hour of video at good quality ).

You need to use a lot of trial and error also.

Divx is one of the easier codecs to use and a good guide can be found here:

x264 ( a free implementation of the H.264 codec spec that many digital TV chans are swapping to ) is probably the best out there for size/quality at a free price, but is a little tougher to get running with and doing good quality encodes.
