 Posted: 02/18/03 - 18:36 Post subject: Question about video editing.
|
|
|
|
I have a question. I recently purchased that Dazzle TV In thing for comps. It basically connects to the computer through a usb port and has S-video and audio ins and stuff like that so you can connect it to dvd players or camcorders and bring the info over. Well, after transferring a hour long movie we made to the computer through the dazzle software, the video was 10 gigabytes. Any clue how this happened, and any possible fixes to reduce the size of it to the normal 350/400 megs a regular hour long movie with s****y resolution takes up? Thanks!

This is why video editing computers have f*****g HUDGE harddrives; those 150-200 gig hard drives are made for shit like this, not for regular people.
I dont know near enough about video compression; so afraid I cant help you

that's just the name of the game....high quality video takes up roughly 10 megs per second i believe.

in 680x400 with a medium-high bitrate my TV recorder uses about 2.5GB/hour, i'm sure its a lot higher for full screen or higher quality
that's just the nature of video editing man, it's 15-25 frames per second and a lot of data to record for each frame

Figured it out. Got the 45 min thing down to 78megs (looks like shit though, playing around with it some more.)

Unfortunately, working with video requires just that - SPACE.
I know in classes, you hear the word "compression!!!!" about 3498574398574 times a day - you can wring out a piece of video/audio into a pretty g*****n compressed chunk and make it smaller (and you often need to if importing it into a program like Director), but it'll look/sound like shit.

First of all, what format is the file in? Assuming it's 10 gig I'm guessing that it is an uncompressed AVI.
Obviuosly you'll want to compress the file, compression has a variety of flavors. They're all lossy. There are virtually no lossless compressions aside from APE audio, which only has 50% compression ratio which is exceedingly bad.
Among the popular compression codecs are Divx and Xvid. Personally I like Xvid simply because it's open source, however divx would probably be good enough for you.
You'll need to go get the divx codec and install it. Then you'll need to get the Radium MP3 codec which I have uploaded to minion.r00tus.com for you because finding working links to it is a pain in the ass. Now that you've got your fantastic codecs you'll need to download and install VirtualDub.
VirtualDub is very straightforward and easy to use, unfortunately I believe you're all retards so I'll go ahead and explain step by step as if I were working tech support for AOL.
1) Open your file up in VirtualDub, if it's 10 gig it might take a while
2) Go to the "video" menu, select "compression" and choose the divx codec. By default the video should be in "full processing mode" but if not, check that (it's in the video menu d*****s!)
3) Go to the "audio" menu, switch it from "direct stream copy" to "full processing mode." Once in full processing mode, select "compression" and find "Mpeg Layer 3." Pick an audio bitrate. The higher it is the better the quality, the larger the file size.
4) Depending on the videos resolution, you may have to resize it otherwise the file will still be massive. Go into the video tab again, select "filters" this time and click the add button. Depending on the size, you may be able to simply use the 2:1 reduction filter, otherwise you'll have to scroll down to the "resize" filter and add your own dimensions.
5) Go to file, and select "Save as AVI" and let it encode.
There are lots of ways to get better compression out of divx, unfortunately as I stated, I believe you're all retarded. I don't feel like explaining multipasses and variable bitrates to someone who is inevitably going to use this knowledge to compress his video tape of him acting like a homosexual with his friends :(
Finally,

Please don't pretend like you know what you're talking about.

Minion, you're a day late 
Edit: Thank anyways though! And yeah, I went with xvid last night and found virtual dub on sourceforge and had some good times. Still fooling around a bit to see what else can be done on this goody.
