Video File Advice
Posted 29 September 2003 - 05:03 PM
A client wants to add a 5-minute video to her site. It's of her speaking. What format is best to use? I've seen .wmv (Microsoft) for a similar type of site, but the video producer is on a Mac and can't provide it. He's offering to send a QuickTime file. I have no idea what format is best.
This is definitely not my area of expertise!

I'd go with .avi if it were me.

(I've probably played them myself, but never paid any attention!)

MPEG-1 I never get any complaints about this format and you wont need the movie to be hosted on a streaming server.
The thing with AVI is that you get a shed load of codecs to choose from. Codecs such as DivX and Xvid can achieve incredibly small file size, with excellent video quality, but the end user probably wont have these installed on their machine.

Now that I have a better understanding of what's going on I might be able to fix it, but I'm probably a bit more techically savvy than the average web user.

My client wanted to put a 30 second video clip online. He gave me a VHS tape which I converted to digital format using a device and software program called Dazzle. The file size was huge, choppy, and small. It looked terrible and I talked him out of it .
Below is the explanation that I gave to my client why the videos do not look good online:
- The file sizes are about 2.7 MB (2,700 bytes), which is huge. This would take almost an hour to open up on a dial-up connection.
- How well you see and hear the video is a function of the userís sound card and video card on their computer. The better the computer, the better the quality.
- The website is on a multiple server, not a dedicated server. A dedicated server is a computer that only hosts one website, so it can send the files to a userís computer faster. Your website is hosted by XXX and they have many websites on their servers, so it takes longer to serve the files to the user.
- The video was converted to a digital format from a VHS format, so what you see is a copy of a copy. If the original was recorded digitally, the quality would be better.
- When you view the video online, you are viewing ďstreaming videoĒ which means you donít have to wait for the entire file to download to see it. You are viewing it as it streams in. The video will start to play even if the entire file has not been downloaded to your computer. When the video is first viewed it is choppy because it is being buffered. This means that the video will start to play after about 300K (bytes) or so have been downloaded. However, if the next 300K hasnít finished downloading before you are done watching the first 300K, the video will stall until the next 300K has been downloaded, and so on until the entire 2.7 MB video has been downloaded. This is why, if you play the video for the second time, it should play more smoothly.
I hope you find this explanation helpful.
