What program do u use to convert to high quality videos?

[TheRemiX]

in new here and i have a question.. I have some high quality mpeg2 files on my comp and their file sizes are HUGE..i need a program that can convert those files into smaller sizes and retains as much of the high quality as possible.. can anyone help me out here? i just need to know what programs are the best. a tutorial would be nice, but i will try to find out how to use the program if u guys cant find a tutorial.. ~thanks

btw: just in case this helps, my mpeg2 files are at least 150 mb in size and im loooking to convert them to anywhere around 50-100 mb.. ~thanks

You consider 150 MB huge? Uh.. okay...

100gig file is huge ... 150meg is tiny ...

I regularly remove 150 Mb from single frames in movies with
no noticeable quality loss. Of course that depends on the movie
and what you consider quality loss.

i think 150 mb is pretty big for a 3.5 minute clip.. im not talking about movie files here.. im talking about music performances

You need to re-encode your file at a lower bitrate. The lower bitrate and re-encoding will both result in a loss in quality. Depending on how low you need to reduce your bitrate, you may need to lower the resolution as well because high resolution at low bitrate = crap quality. So low resolution at lower rates may be better, but you need to judge for yourself.

Avicodec will analyze the file and tell you the resolution, running time and bitrate, from there you can select a target resolution and bitrate. I recommend using TMPGEnc and 2-pass VBR for best quality at a small size.

Post the results from avicodec and we can help you choose target resolution and bitrate. (maybe)

Now I see. Details always help.

But now we need to know where you'll be viewing this, player or computer. And let's not forget resolution and source.

I use 352x480 3420k VBR on my DVD player, and 23 minutes = ~700MB. That's about 30MB per minute.

150MB for a 3.5min MPEG clip is, say, 5.7Mbps average bitrate. To get this file down to 100MB then you need to lower the bitrate to about 3.7Mbps average. You're going to loose quality expecially if these files are 720x480.

I wouldn't waste effort on this project, just use another disc.
