File size reduction

[Kino]

Hi,

I'm using vlc as a pvr to stream video to a file. Using the default settings a two-hour recording results in a 5.3 Gb file.

So, I have two questions:

1. What parameter do I change to reduce the file size during recording to, say, 1.5 Gb per hour?

2. Is there a method to reduce the file size after recording (not just compression) such that I could fit a 5.3 Gb, 2 hour recording onto a dvd?

Thanks in advance.

Just for the record the settings are currently:

cvlc pvr:// :pvr-device="/dev/video0" :pvr-radio-device="/dev/radio0" :pvr-norm=0 :pvr-frequency=855250 :pvr-bitrate=-1 :pvr-caching=300 :pvr-width=-1 :pvr-height=-1 :pvr-framerate=-1 :pvr-keyint=-1 :pvr-bframes=-1 :pvr-bitrate-peak=-1 :pvr-bitrate-mode=0 :pvr-audio-bitmask=-1 :pvr-audio-volume=-1 :pvr-channel=0 --sout file/ps:///home/xxx/vlcmovie-%d-%m-%Y-%H:%M.mpg

You have to transcode, if you want to downsize it.

I'm sorry, but I'm a relative newbie at this - you'll have to be a bit more specific.
