Linux Real Time MPEG Compression?

Posted by Cliff on from the squashing-video-chunks-while-u-wait dept.

aszoth asks: "I working on a project that is going to require approximately 4 hours of video recording per day for about two months. We are currently using DVM tapes, however the extraction and compression time has left us with a large library of tapes un-converted. We are considering other methods, in particular real time MPEG 2 or MPEG 4 Compression. We also would like to be able to slow down our frame rate from the 29.7 fps to something along the lines of 5-15 fps. I am wondering if any one has any suggestions on possible ways to do such compression (or get similar results) with a Linux box. Thank you for any help you can give."

    Seriously. Do some searching for video capture applications for Linux, and then look at Linux MPEG-4 encoders like Xvid. Then Google can probably also point you towards several how-to guides. Why are you asking Slashdot? Ask Google.

      Why is this person asking slashdot? For an answer. Google may be great but there's a lot of garbage out there. I'm sure the poster was hoping someone could help him out by sharing some personal experience.

      It's a great compliment to the community that people can ask a question assuming there will be an informed, helpful response. The knee-jerk "google it" reaction that is so common these days is tearing apart this vital facet of the community.

      this whole /. thing is about community, people. let's be helpful if we can. and remember, there's no such thing as a stupid question, just unhelpful answers.

    MPEG is fine for archiving, but its not that good if you want to edit later. MPEG encodes the difference between key frames. This makes it hard and expensive to edit frame-by-frame.

    What I'd like to know is if there are any standard formats that are good for cuts. DV is great, but takes up a lot of space (3 minutes on a CD). It'd be nice to archive easilly editable source, just at a lower-than-dv quality.
