difference between .mpg and .mpeg ?

[sandra]

Hi,

what's the difference between these two ?

Videos I make with my webcam have .mpg file extension. Formats accepted by YouTube are mpeg2 and mpeg4, but not .mpg...
So there must be a difference in kind?

no difference.

The only reason a file is ever given the "mpg" extension is because older file systems and operating systems are restricted to 8.3 filenames- that is, 8 letters, a period, and a three letter extension... in this case, MPG.

MPEG itself is really just an encoding standard; for example, an AVI file could use MPEG encoding.

if you need to, you should be able to simply rename the file in question to have an mpeg extension.

yes, I may be confusing file- formats and codecs .

My cam makes videos that are stored as .mpg-files on my hard disc.

When I want to put this on YouTube I have to put a codec on it, so to speak?

MPEG stands for moving picture expert group.  It was a group of people from many companies to standardize the way video was handled for cable, satellite and computers.

The first version was MPEG-1 and MPEG-2 and MPEG-4 are updates on how the encoding and compression is handled.  Basically version numbers.

People keep telling me that I look like a 15-month-old.
Quite a feat, I'm actually 38.

AMAZING! Let me guess, you've discovered the fountain of youth?

Back on topic........ You should be able to upload the videos directly to YouTube.

I haven't tried yet to directly upload.

What I did try though:

Make a test video with my webcam, saved it on my rig and then imported it to W Movie Maker ( despite it being the Vista version that is supposed to not accept web cam stuff).

I then published this video in another folder (as .wmv i think) and then uploaded it to YT.

It appeared to work 
No crunchy sound, no additional minutes added.

However, I've deleted VirtualDub that I had downloaded. I'm far to dumb for that for now.
