there are way too many video file types for me to figure this out.:confused:

Today is the first day I came across an .m1v file.:Q

m1v is just mpg. An mpg file can contain a video and an audio stream. m1v is just the extension for an mpg video stream.

That's useful information. Thanks.

If it's just a mpg video stream, why wouldn't all of my video players open the file? Would I have needed to d/l a specific codec or something.

When you say most compatible between various players that leaves a lot of room for interpretation. Also are you talking about software players on computer or a hardware based player like an ipod? If software then it's usually a codec that's actually doing decoding not the player. If you truely mean the MOST compatible for viewing on computers then your safest bet is probably mpg1 or a Cinepak encoded avi. DivX has been around long enough now that you should be able to play it on a lot of computers, but again they need to have downloaded the codec.

Which video players are you trying? Should work fine in Windows Media Player. I have no clue if you are using Linux though.

I had the feeling I wasn't asking the question properly.

My dad has is putting his house up for sale and I was thinking about putting an two or three minute video-tour of the house on my website.


How does a flash file compare to mpg1 or avi?

avi isn't a form of compression. it does mention mpeg. you didn't read closely enough, i guess.

Sorry. I had never heard of H.264 codec so I just glanced at it.

What is avi if it's not a form of compression?

I have several video players installed. Real Player worked but IrfanView didn't. IrfanView plays most of the files I d/l.

Ahh I see the question is entirely different for web distribution. If you want the person to be able to view the video in their web browser then I would recommend one of a couple of formats. (1) a wmv file. WMV is microsofts answer to web distribution of video and properly encoded and embedded in a web site should be viewable from most windows PCs (2) a quicktime .mov file. Quicktime is another very popular method of distributing video on the net though not as widely supported as WMV. (3) a flash file. you can import avi's into Macro..(sorry Adobe) Flash and export a flash file. This will be playable on most web browsers.

With ALL of the above formats there is the issue of server support, properly embedding the file and file size. You can get a nice small file size with just about any of the above with enough work, but video on the net can be and ugly affair :(

It's a container format. It allows one to bundle video and audio formats of various types together in a unified format for distribution. The Video and Audio streams inside could be just about any compression format.

I would recommend that too but he has since made it clear that he means the video for web distribution, streaming it looks like. In that case WMV, quiktime, or flash would be better.

I lucked out big time! Some very knowledgable folks were on ATOT when I posted this thread!


In order to play the Flash File, the person viewing the file would need to download a browser plugin, right?

There must be some advantage to a flash file (I'm assuming) since You Tube uses it.

Well yes the flash plugin comes standard with lots of browsers.

How does youtube convert the uploaded videos to Flash files? Is it automated?
