    Can anyone confirm that it is possible to convert AVI(source was digital camcorder)to DVD without visible loss of quality. I have tried building my first home DVDs from camcorder recordings by using WinDVD Creator as well as Premiere 6 and Adobe Encore, but the result is identicle and very much worse than the original AVI files.
    My primary problem is the loss of DYNAMIC RANGE of the video. In the resulting DVD bright, sunlit areas have lost all detail. While in the original AVI file the transition from dark to bright areas was smooth, it is now abrupt and harsh.
    I would post some screenshots here if possible and if I knew how.
    logically, turning 12Gb AVI into a 3.8Gb MPEG-2(DVD) should entail some compression=quality loss! But does this mean that I can never get the quality I see by connecting my camcorder to the TV when burning the movie to DVD??? There's got to be a way?

    I posted another thread on this issue, but no one seemed to reply. I would terminate this first thread, but I don't know how

    Any help is much appreciated.

    hi

    i dont think you will get an app that will create a dvd from avi and not loose quality!

    but there are apps that will do there best to get near the same quailty as possible!

    you say 12gig AVI ? well man that should equate to some thing like 15 dvds! or more! after converson to dvd standard! avi get bigger!

    as a first try use divxtodvd its free and will take avi and convert to vob/ifo/bup but not sure it will cope with size of 12gig avi?

    also other apps that are better will take for instance 700meg avi 3/4 hours to convert for best quality! at output 3gig, now you can see the vast size of your avi!

    The Size of the AVI file has no bearing on how big it will be after encodeing to Mpeg-2/DVD...Because the AVI is 12gb doesn"t mean that the Mpeg-2 file will take up 15 DVD"s, It might be less than 500mb...

    What determines the Size of the file after encodeing to Mpeg-2 is the Length of the Source File and the Bitrate used to encode it to Mpeg-2....

    Encodeing from one Format to another is allways a Lossy process so you will allways loose some Quality but if the Source File is of High Quality and you use a Good Quality mpeg encoder useing a Descent Bitrate then the Quality Loss should not be Very Noticeable..

    Just make sure you use a good Quality mpeg encoder Like Tmpgenc or Procoder or CCE SP....Also there are some Settings in some encoder that need to be set up properly when encodeing DV AVI files to Mpeg-2 so you don"t loose Quality through Colorspace Conversion...If these settings are not set up properly your Colors will look all washed out and Dull...

    You can read up on the DV Format here:

    hi

    thx minion, i was always of the thinking that they got bigger? every avi i have done has....

    but i relativly new to this avi to dvd stuff and thats what i come across so far, thats good if you can get them smaller

    i use avi2dvd / CCE and film machine / CCE and divxtodvd all went from 350meg to 2/3gig....

    The Sometimes get bigger and they sometimes get smaller depending on the Codec used to Compress the AVI file...

    One Minute of Full Resolution Uncompressed AVI Takes up about 1.2gb so you can imagine home compressed Formats like XviD and DiVx are which are probably the Format most used in the Movies you download off of the net...

    Kartalovp"s AVI Files were transfered from his Digital Camcorder so they are Compressed to DV AVI format which is not a very Highly compressed format, His 12gb AVI file was probably only about 60 minutes Long.....


    Cheers
