Re: Streaming Video to Demo my Software



Though you did not say what the original video resolutions was here's my 2
cents. If your original was a larger resolution than your compression target
there will be fuzzing of the background. If you compressed it in one-to-one
resolution and it fuzzed out, then you added too much compression.

When using Windows Media Encoder I don't try to cater to the user's
connection speed so much as I try to end up with a good final output. Mostly
I output to the broadband user. The settings I use for broadband are as
follows:

1. Begin a Custom Session
2. Sources tab:
Naturally the choice would be from a file
3. Output tab:
Archive to file, uncheck push and pull options
4. Compression tab:
Destination: File download computer playback
Video: DVD quality 1Mbps CBR
Audio: CD quality CBR
5. Video Size:
Crop Method: No cropping
Resize Method: No resizing
6. Attributes: Whatever you want there
7. Processing: None
8. Leave all the other settings as they are.

Now, if you have a 30 minute project at 720x480 29.97fps 48kHz stereo audio
the file size would be somewhere in the neighborhood of 249MB. I know that's
a big file, but it will look great on playback. I have an example of a
project we did of last year's birthday celebration for my friend Al Matthews
who turned 102. He's 103 now and going strong, still drives a car at the
true speed limits, and walks about a mile a day.

Anyway, the link to this file is:
http://digitalvideosolutions.com/video/Al_Matthews.wmv if you care to see
some of it. The project is 1 hour and 2 minutes. The file size is 498MB. It
is full resolution 720x480 0.9 pixel 29.97fps non-interlaced with CD quality
stereo audio. On broadband (5MB) the file buffers and plays smoothly,
considering the speed of your system. On one of our AMD 1GHz machines
(Pentium 3 level) it plays a little jerky. On a PIII dual 1GHz machine it
plays smoothly, and on all our faster P4 machines it plays just as smoothly.

If you really need high quality playback perhaps you should try to find a
way to break these demos down to ten minute seqments for easier download for
those with dial-up. Maybe streaming is not the way to go if you want to
preserve quality.

I am looking for a way to stream my video demo of my software. I have
the video is .avi. I compressed it into a dozen different formats. But
none of them keep the non-moving backgroun image clear. I am demoing my
software product. And most of the time only the cursor is moving. I
would expect to be able to compress this very much without losing the
detailed resolution of the screen. Real Player was the best I found
(7:1 reduction in file size but the background screen was still fuzzy).
I would like to be able to stream a 30 minute video demo and it not be
too large of a file download. I would like to use a format that does
not require a custom player like Real Player. Any one know a a great
compression algorithm for a streamable Software Demo????

Thanks
