Which video format WILL you prefer when buying it online?
 

We are planning to sell video content online. I wonder will you prefer higher resolution (and at the same time much bigger file size) than MPEG-1 with its shitty 352x240 limitations?

What do you think about 640x480 in a Quicktime MPEG-4, cause with a Quicktime it is very easy to convert to any other format.

MPEG-1 is limited to 352x240?

Yep,
NTSC - 352x240
PAL - 352x288

yes why?

Isn't PAL 640 x 480?

But I still didn't get the answers, only questions :( Do you need better resolution and if so in which format?

There is a difference between NTSC and MPEG-1

It's possible to make MPEG-1 files at bigger resolutions than 352x240

Yes, but it will be useless.

Depends how high the bitrate is that you encode it in. But I think 352x240 encoded at a high bitrate is good. Users can always do the view ---> zoom ---> 200% thing if they wanna see it bigger, but then again, most surfers are dumber than shit so they wouldn't know how to do that.

But if you are encoding with Windows Media Encoder at higher resolutions, 352x240 will not be enough for it.

You are not limited to 352x240.
I will quote from the source you just used to say that you are.

Can MPEG-1 encode higher sample rates than 352x240x30 ?
Yes. The MPEG-1 syntax permits sampling dimensions as high as 4095 x 4095 x 60 frames per second. The MPEG most people think of as "MPEG-1" is actually a kind of subset known as Constrained Parameters Bitstream (CPB).

I would suggest that you go buy Sorenson?s Codec package and see exactly what you can do with Mpeg-1. This post makes you look uneducated in the art of video encoding and is not good for your new business venture.

You are wrong! :BangBang:

The first:
"The coded video rate is limited to 1.862 Mbit/sec." If you will go further at the same bit rates MPEG-2 quality will be much better, so as I already said it is totally useless to make higher resolution in MPEG-1 streams.

The second:
Sorenson is based on MPEG-4 technology and mostly aimed for QuickTime encoding, not for MPEG-1.

And the last thing:
I was asking about the possibility to buy DVD MPEG-2 (MPEG-4) quality videos at the price of MPEG-1. So as I see nobody is interested in it.

It looks like you are totally newbie to video encoding :321GFY

ok.
Your right.
I know not what I speak. :thumbsup

1) You're confused my son. The ONLY reason anyone uses mpeg-1 anymore isnt because of its amazing quality or impressive compression but because that it is the most widely supported format on the net.

The only advantage to mpeg-2 for what you're doing is giving people who wish to re-encode their own shit a decent copy to work with but when it comes to end-user support, forget it.

2) Sorenson does/can compress Mpeg-1 compatiable files which are still just as widely supported and isnt solely based on Mpeg-4, maybe you're thinking of Sorenson v3.

For the most part an mpeg compressor is a mpeg compressor but some programs tend to do it better. Oh, and yes you can go over 352x240, but i dont see how that is useless.

Alan ummm.....
ummm.....

Oh nevermind....

Alan,

What type and lenght of content are you working with? also what kind of terms/security are you wanting to setup?

Are you looking to setup these vids inside a subscription site or setup a subwscription to a set of movies (i.e. you can watch 10 of these 100 clips a week, but you can watch them as many times as necessary) Are you looking to stream or download or progressive download with DRM?

I may not know a lot of answers, but I know a lot of questions.

Even if you are always encoding to 320x240 with MPEG-1 the quality will be much better when the source has the higher bitrate.

But even now people are starting to rent online DivX videos with true DVD resolution.

High broadband surfers are ready to pay more for the quality.

short videos, 10-20 minutes - it will be around 200 Mb each

i am developing several small paysites now and such clips will available for download inside members area, without any protection (like drm)

as for me i am sure that most adult videos will be downloaded from net (not purchased offline), sure not tomorrow, but VERY soon

Did you say you were or were not going to use DRM on the files?

I am not going to use DRM.
