Compressing .avi

Dempsey

Can .avi files be compressed signficantly and then burnt to cdr while compressed etc.

Saruman

Yes.. plenty of compression software out there.. i.e. DivX

Dempsey

Any others cause divx doesnt seem to install properly on me pc cause of the stupid spyware sh!te.

Look them up plenty of compression tips.

DFont use DIvx5 and you wont have spyware

Drazhar

that should have been "Dont use DivX 5"

Saruman

Or do use divx5 and DONT INSTALL the spyware! You dont have to you know.. just take out the tick during the install!!

Do you mean compressing the video and audio streams or compressing an existing AVI in terms of zipping it or something?

DivX 5 is pretty good for this sort of thing - people tend to use MP3 for the audio stream. Try VirtualDub (www.virtualdub.org) to actually do the donkeywork if you don't have something commercial - VDub is free and pretty good for this sort of stuff. Remember, you'll have to install the relevant codecs first (the pre-installed Fraunhofer MP3 codec will not encoding at rates above 64kbps - look for the LAME codec (google will find it) as a free alternative.

If you just want to compress an existing AVI without losing detail (compression algorithms such as DivX are lossy, in that they selectively remove detail from the video stream (just like MP3 does to audio) to make it easier to compress) I find that RAR does a better job than the various ZIP compressors - be sure to enable multimedia compression and choose to make solid archives.

Its a made .avi file and it can't be made again. If i could make it again I could make it smaller, no problem, but its made and its about 200MB too big for a CDR. I'm only hoping.

Saruman

200 mb is too big for a cd? Do you mean 2000mb?

Dempsey

No, you misunderstood me. The file is about 853Mb in size(guessing). I need to reduce it's size by about 200Mb or get it below 650Mb or 700Mb for a CD-R

You could split the file into two chunks to spread it across 2 CD's.

Winzip will do this, as will other 3rd party apps.

You could also split the file with virtua dub and hten you have a 2 cd avi ene even over lap where you cut it if you want.

Drazhar

If your gonna split it, a little freeware program called HJSplit is bloody brilliant, so easy to use, im sure even accountants could

hj split is brillo and its tiny only like 40k as far as i remember so ya can stick it on cd with the other files! sweet.

Eh? What do you mean it "can't be made again" - do you mean you don't have the original source material? If you check what codecs are used for the audio and video, maybe you can recompress it at a lower bitrate (with the associated loss in quality) to get it onto one CD?

Tried the 2:1 compression algorithm ............. it looked worse but this is the best part... it was 18.0Gb.....hmmm, maybe i need someone who done this before to point the way for me
