I deleted, by mistake, the original message so I have to forward a response to it. It seems to be easier for me.   I assume you want to e-mail your large files. If this is the case you can create an account with Yahoo and/or Lycos and try from there. If your ISP is AOL run away, asap.   To reduce the size of a file that is to losslessly compress it, on linux: gzip -f what you get is .gz the size of the compressed file depends on many factors one of which is the kind of file; I never compressed video files. bzip2 -z is another way to compress files; it achieves better compression rates that is, the compressed files are smaller, up to 30 per cent smaller, if you are lucky what you get is .bz2 To decompress: gzip -d .gz or bunzip2 ........ .bz2   I do not remember the option, I think it is x, I am writing from the microsoft trash and I cannot look it up, look up the man page for bzip2.   If gzip and bzip2 do not help, split the files. I know there are ways to split on the windows trash, I have not been able to find anything that would work on Linux. If you search the Internet (use altavista, not google because google spys on you) for "file splitting" you will find many share- and freeware file-splitters for the windows-trash.   If you think nothing works for you so far, sit down and write a file-splitter for Linux  yourself          Merry Christmas!!           --- On Sat, 12/12/09, Matt Graham wrote: From: Matt Graham Subject: Re: File size reduction in Linux?

Nope.  You're the first person who's ever needed to resize a bunch of video files.  Actually, there's a very useful utility called ffmpeg that can re-encode audio and video to a ton of different formats.  However, it's not really n00b-friendly.  I used the file at http://crow202.org/~mhgraham/presets.xml (originally part of a frontend written in some bizarre dialect of Pascal) and a bit of shell to come up with this: #!/bin/bash # converttoflv.sh # no error checking at all.  Converts first arg to second arg ffmpeg -i $1 -vcodec flv -f flv -r 29.97 -s 320x240 -aspect \ 4:3 -b 300kb -g 160 -cmp dct -subcmp dct -mbd 2 -flags +aic+cbp+mv0+mv4 \ -trellis 1 -ac 1 -ar 22050 -ab 56kb $2 ...which, when invoked as "converttoflv.sh thing.avi thing.flv", will turn thing.avi into a 320x240 FLV with a low bitrate audio stream at 22KHz and a 29.97 frames/sec framerate.  The resulting videos are suitable for FlowPlayer and probably YouTube.  There are a metric ton of reasonable presets in the XML file above, and they have descriptions.  You can roll your own script(s) from that in about 30 seconds depending on your needs, or modify the command lines to get something different. There's probably something more polished out there, but the video re-encoding projects I found via freshmeat/sourceforge were all half-finished or special purpose. -- Matt G / Dances With Crows The Crow202 Blog:  http://crow202.org/wordpress/ There is no Darkness in Eternity/But only Light too dim for us to see --------------------------------------------------- PLUG-discuss mailing list - PLUG-discuss@lists.plug.phoenix.az.us To subscribe, unsubscribe, or to change your mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss
