Thread: Avi problems? (you tell me)

  1. Default Avi problems? (you tell me)

    Ok, im not gonna pretend im an expert at this video editing biz so i just neeed advice because im failing to understand whats going on with pinnacle studio 9. OK, here we go. The first time i captured footage from my dv camcorder i chose mpeg 2 as eventually after a bit of tweaking i want to put my vids on dvd. Sounds easy right? So it finishes capture then when i look in the folder where i've saved the footage i have the mpeg2 file and surprisingly to me an avi file of the same footage? Should this be happening? Anyway, so i view the two files and it appears that the avi file is the best quality of the two recordings. Ok great, Ill just upload the rest of my vids the same way then use the avi files for my dvd and editing.
    Unfortunately, things are never easy are they? I captured 4 vids and only 2 of them produced the additional avi file's. Any ideas what the hell's going on? Why is avi better quality than mpeg2 (sharper picture - just what i want)? Can i just somehow capture the footage as an avi file?
    Any advice on where i am going wrong or just any advice in general for me to be getting the best quality results that i can. I would really appreciate you're help with any of this. Thanks in advance to anyone who's kind enough to help me.

    I'm not sure about why you got the avi files as well as the mpeg ones, but i can answer your other question.

    The avi format is 'raw' digital video with no compression at all, and so therefore it is the best quality that you're going to get. The mpeg file is compressed, and therefore there is a loss of quality. If i were you, i'd capture all your video as avi, and then compress it to mpeg afterwards. This makes editing much faster as well, because it means that the editing program doesn't have to decompress anything.

    Hope this helps.

    Just a minor correction on what seymore posted: the term AVI refers to a'wrapper' or 'container' to play video on a Windows O/S. An AVI file can contain video encoded in a variety of formats: from uncompressed video, to DV (approx 5: compression) and highly compressed MPEG4.

    when you're on the capture screen, in the bottom right hand side you should have the disk meter graphic showing which drive you are using to capture on and the space on it.

    on that you also have the three options for capture, they are

    first will be dv-avi, ie uncompressed, best quality
    second will be mpeg capture
    third preview quality, which means that when you finish editing and go to render your project studio will need to then go back and capture all the clips again in full quality.

    just click the button next to the one you want to use and then press start capture.

    hope this helps

    Thanks a lot, I've got my avi files now. Ok, now we move on. Am i right in thinking that when i come to put my project consisting of avi files onto dvd disc that they will take up a lot more space than other formats such as mpeg? what do some of you lot do? should i complete a project using avi files and then convert it to mpeg? Would i lose the quality that i have with the avi files when i convert to mpeg? Any advice would be nice.

    If you're going to burn it to dvd then yes, i would convert the final product to mpeg2. You will lose some quality, but not a very noticable amount.
