RE: Everyday digest / Loop Videos / How to get file size down!



2pass will give about 20% better video quality  when  using WMV. WMV tends to have fuzz lines. If you are willing to encode again try 2pass and/or MOV (Quick Time).

if you'd like to know more about video encoding/codecs visit doom9.net. It where codec engineers from around the world hangout and discuss such topics. They can get very deep.

Aspect ratio: 13:10
Audio codec: Windows Media Audio 9.1, 32kbps, 22kHz, stereo (A/V) 1 pass CBR

Basically, I covert from mpeg to wmv using the color pocket PC option. Seems to work the best.

what is the streaming rate?


Todays market calls broadband 200 - 300 kpbs. The common frame size is 320x240. Players can resize better than encoders can encode larger frames.

Also, be sure to sue 2pass encoding when converting to WMV, RM, or MOV. The first pass maps pixel movement. The second pass encodes based on pixel map.  I wont bore you with the details.

Have you tried converting into MOV format? Is a very friendly data type.

I've been meaning to ask a related question after seeing one of my looping videos in this digest from Kim. It has to do with finding the best quality yet smallest file size for videos. For this video below, and the others, they were shot professionally in a studio with three camera men, producer, sound engineer, etc...and there was a some good effects like panning or fading from camera to camera, superimposing camera shots, and so on. I was given the master on Super VHS, which I paid to have converted to DVD. I ripped the DVD to the best quality mpeg (DVD editing quality), then converted that to a series of Windows Media (wmv) videos. The quality of these wmv videos is acceptable...no overt choppiness in the sound. movement is relatively smooth, etc, but the files are still large. A 10 min. 25 second video of mine is 15MB and the size is 208 x 160. 
 
However, is there a media format that will get the file size down even further without loosing quality? I've tried Real Audio...no luck. I hear Sorensen Squeeze 4 can do this but I'm too cheap to buy it. http://www.sorensonstore.com/product_info.php?url=http://www.sorensonstore.com/products/sq4cswin.html  It sounds like the ticket though.
 
...looking for other options, or I just suck it up and accept a 15MB file size for a 10 minute video.
