    i know it's impossible if u reduce video size , it will surely loss some quality too. but i used to watch Graboid Videos and every drama episode i watched there was in 400MB only but with remarkable video quality. and every movie i saw there in 700MB but v.v.good quality.

    i just want to know that is it the Function of Video converter who converts video without (or with minimum) loosing video quality. if it is so , then please recommend me some best video converter even i have to purchase it, doesn't matter.

    I believe (and I am by no means a video expert!) .mkv is a good size reducer, whilst maintaining a pretty good quality.

    I use the free Handbrake app to crunch 1 hour television shows to 350 megs in size. Show more than 1 hour I convert them to 700 megs in mkv format (H264 codec). They are nearly as good as the original mpeg2 file.

    Make sure you read the manual as well, as there is a lot of useful stuff in there to help you convert files...

    Re: reduce video size with no video qualty lo

    i never get in search this video converter. it's great software. i m trying to read it's manual but currently i m converting a video and there is two options.
    Regular:
    >Normal
    >High Profile

    when i choose Normal, there is an option of Anamorphic which changes to 'Strict'


    but when i choose High Profile, Anamorphic option changes to 'Loose'
    Widh=1920, Height=0

    can you please explain about Anamorphic option please ?

    please tell me all your specification you use to convert your video. i converted 350 MB youtube video (HD 720p) in to MKV format by making
    Constant Video Quality to 100 %
    Frame Rate: Same as source
    Anamorphic: Strict

    and it converted the out put mkv file into 5GB :(
    please tell me your settings so that I can attain nearly original quality with minimum size.

    Re: reduce video size with no video qualty lo

    To start with I used the Regular / Normal profile, I then modified it with these four settings in these pix.

    Only edit these four setting leave the others at the default settings.

    Once you have set them up, click on the Add button, and this will save it with whatever name you want for it. I used ABC / SBS Doco's.

    These settings will give you a finished file size of 355Mb approx...

    Re: reduce video size with no video qualty lo

    yes , it works very well :). i have two questions
    i. what should be the criteria by which i should reduce my Video size like i have 1GB video file (.vob format). how should i guess that this is the limit where i will get nearly original video result with less size. whether i should reduce it to 300MB , 700 MB or what ?
    i know it's up to me whether i do it 100 MB but an expert may know that i should divide original video size by which number so that i will get the figure (which should be the size of my reduced file)
    i think i confused the question :(

    ii. if i have movie in 480p , then what i should give picture size (width) ?

    Re: reduce video size with no video qualty lo

    That file that shows in the first pix "As It Happened" started out at 3.4 gigs in size and I converted it with the H264 codec. so it works out at 10% of original size for that one. Also that file is around 50 minutes in length.

    With a 120 minute plus movie recorded off of the TV, it will be around 6-7 gigs in size and it will convert down to around 700 megs.

    To do this you will have to change the target size in the third pix from 350 to 700...

    Re: reduce video size with no video qualty lo

    you mean the input video size should be the 10% of orignal size with H264Codec. for example if i have video 1024MB , then my input video size should be 10 % of 1024 i.e. 102 MB ?

    Re: reduce video size with no video qualty lo

    Using your example of a I gig file you probably could shrink it down to 100 megs but it may be blocky.

    The best way is experiment with the settings till you find a size that is acceptable to you.

    This what I did to get those size I use, the best test is to get a video with a lot of flames in it. Then reduce the size till it gets blocky, then adjust the file size till they are gone and then use those setting for them all...

    Re: reduce video size with no video qualty lo

    ok i get it. i have 4GB RAM of 800Mhz. but still i feel that it was very slow conversion of 350MB size of video file into 100MB. is there a software which uses all of my RAM only in conversion so that i can make my video conversion fast ?

    i mean even i was not doing any other task and there was only running video conversion process but that was slow. so i want to use all my RAM and CPU in conversion. is it possible ?

    Re: reduce video size with no video qualty lo

    Video conversion is a lengthy process to get quality results.

    I use a AMD 6000 dual core cpu and have 4 gigs of ram for my video conversion

    The 350 meg files take around 20 minutes to process. The 700 meg files take up to an hour to do.

    I have found that the less you use the computer the quicker the file will convert, so no multitasking...

    Edit: If you go to Tools / Options / do the following...
