Hi,

Does anyone know how to convet a file to an uncompressed (normal) AVI video file with mencoder? The reason I am trying to do this is so I can turn the uncompressed AVI files into realfiles (with helixproducer's software) so that I can produce a realfile small enough to upload to the internet. Right now the file(s) I have are around 100MB -- too big to upload to the internet and/or a website (downloading a 100MB video file takes a long time too). I was hoping to convert the file(s) to uncompressed avi and then onto realfiles with realnetworks' software. The files are in mpeg4 format.

Thanks,

if u would like to rescale them
why don't u try this

mencoder input.mpg -ovc lavc -lavcopts vcodec=mpeg4 -vf scale=640:480 -o output.avi

thanks -- that's pretty close though I need the output to be an uncompressed AVI, as it's the only thing realmedia's software ("producer") will accept x.x

in that case u may preserve the scale ratio i.e keep that to 640:480 as u like

uncompressed? that's *not* normal... normall avi are compressed with some form of motino encoding... try using the -ovc raw option to dump the uncompressed video.

personally i'd ignore real and do more video encoding but then i don't have helixproducer....

thanks -- it's a pecularity of helix/real's software though: under linux it can only have 2 types of input: an actual video input or uncompressed (full frame) AVI. I'd love to *stop* using realmedia, though I don't know of any OSS/free equivilent. MPEG4 I guess is as close as things get, but it's hard to make a small size file for usage on the internet
