When I want to burn, how can I make file size smaller?

    I'm using VSO to covert my .avi (anime) into Video_TS folder so I can burn it with DVD Decrypter (I dunno how to make it an image - anybody know?) but for a file with the original size which is 175MB to jump to over 500MB per file is way to much for a single 4.7GB disc.

    How can I keep the file size down? And will converting it to an Image file instead of the Video_TS thing help keep the file size down as well? (but I dunno how to do that so can anyone explain help?)

    Thanks for both questions

    I don't use DVD Decrypter so, don't know for sure, but I imagine any image file will equal a Video_TS file. Could be wrong, though. File size is directly related to the bitrate used, so get yourself a good bitrate calculator and keep the bitrate within the media used. Also, burninng to the edge of media (especilly poorer products) can result in problems. Here is a good calculator:http://www.videohelp.com/calc.htm

    Alright but say I want the bit-rate to be atleast good quality (not too high but good enough) is it common for a 175MB avi file to shoot up way over 500MB?

    btw the original Bit Rate is 128kbps, that is good enough. but why doesn't the process of turning into Video_TS keep the same bit rate? (if it is then I dunno what's up with the *huuuuge* file size increase)

    I wouldn't say it was common for an avi to increase to over a file size of 5000 but I see it quite often. You will have to keep bitrate around 4300, (unless you use Dual Layer-need a DL writer for that) for DVD and the quality shouldn't suffer as long as the avi is good quality. There will be a difference in quality between your PC and on a standalone, though. The 128 sounds like the audio bitrate. I am not a guru on this but as I understand it, avi is just a container and the process of converting (extracting) accounts for the size difference.

    hello

    @ Lemngying

    i dont see what difference it makes,as long as you are happy with the quality
    unless of course you are putting more than one avi on a dvd disk

    the only setting that can control the output size in convertxtodvd is

    settings/encoding/target size/custom

    cheers!!

    ^Well im trying it, the original value was set to 4400 (4.4GB) o_O and i set it waaay down to 200 (MB)

    that wont totally mess up the quality would it? o_O (The original file is 175MB)

    hello

    i dont see the point though!!!

    any reason why you want it so small,most guys want it bigger...hehehe

    175 mb to 500mb sounds about right to me,but give it a go,
    i would test the quality first before burning it

    cheers!!

    A bitrate setting of 200 will probably ruin the quality, the lowest I ever used was 1200 - 1500 for multiple episodes on a DVD. As I am not familar with VSO, use the setting that ps2hacka gave you and don't change the bitrate setting from 4400.

    Well the average bitrate is at 1500.

    Anyway I never changed the bit rate but the "Target Size" as ps2hacka said it.

    Settings > Encoding - And select 'custom' under Target Size. (I think it was originally set to DVD-5) so thats why I tried to change it to 200MB. Although it automatically changed to 330MB afterwards.

    I have no idea what these settings for DVD-5 are but that's the one you want; blank media you purchase is DVD-5 as opposed to DVD-9 (commercial DVD which holds twice the data) you rent or buy. There are others as well but these are the two main ones.

    hello

    thats right Lemngying,you cannot change the bitrate using convertXtodvd,only the target size

    you still havent said why you wanted to get it so small?,

    personally i would just let the app run its course,even though you set it to 4300mb,a single avi wont get near that anyway,a single avi is more likely to be around 2.5 gb
    i just keep that setting like that in case i load in a film that has been split over to avi files

    The only reason why I'm pressing for a small file size is to get 25 episodes of a series onto a single DVD disc (the disc is 4.7GB)

    My friend can do it so I'm trying to do the exact same. The original files for each of them is 175MB. And there is 25 in total. However the lowest file size I can get them to is 330MB each. :(

    I don't know how you can burn 25 episodes to a dvd and maintain any kind of quality. I assume their 1/2 hour episodes but even at 22 minutes each, that is over 9 hours. Maybe your friend burned them as data and can play them, maybe a different encoder but I am sure the quality would suffer, maybe Dual Layer but you mention 4.7G and even then, I don't think it would work. I burn a weekly episode (350 MB) to dvd and the resulting file is 2.5G. I have burned 4 to a dvd with no quality loss but that is pushing it, I think. I would see what your friend did and follow that or give him a blank dvd to copy for you. Good luck
