Try QuickTime...better formats and codecs.

I tried to reduce the fps to 15, the file size was 11,667. I tried 30 fps, and 5 keyframes, the file size 11,671. SO for some reason I am not getting smaller file size. However, what's happening is when I reduce fps from 30, or keyframe from 5 or audio from 44100 - the audio gets toally messsed up. Any further tips, on how I can optimize the file size for this video for web would be greatly appreciated. Thanks.

My comments related to a specific question and while some are relevant to Renee's objective, I'd amend my answer somewhat for this situation. The four biggest impacts on the quality and size of a web compression are resolution (width and height in pixels), frame rate, key frames and source material. The last one is the first consideration. If it is made up of high motion it will be difficult to impossible to make a small file that looks good. High motion doesn't just mean kick boxing or extreme skiing. It can be short clips, zooms, pans and tilts, noise from analogue conversion, effects and dissolves - anything that requires the encoder to spend precious bits wastefully. If the source material isn't challenging, try 320 X 240 at 15 fps and note the number of key frames in the default. If you don't like the size results but the quality is ok, do it again with fewer key frames. The URL below links four video files I recently did with Procoder Express. If you look at #3 and 4, you will see the difference the extra bits make, and where. You can also decide whether either version is up to your quality objective. The first (3) is at a combined data rate of 108 kbps, while #4 is at 272 kbps. I usually don't encode at that low a level but for this project I needed to experiment at that end. http://www.contentshop.tv/procoder.htm David Hurdon At 06:28 PM 4/5/2005 -0700, you wrote: Hi! I have a 5 minute video clip, which needs to be compressed for internet. I created windows media 9 version for 256 k download and the file size is 11+ MB. Earlier I have had good results with this format for web movies. 11+ But this one, I am not happy with the resolution, and need to bring the file size to about 5 MB. What do I need to do. I could create WMV for 128 K, to reduce the file size but that would also compromise the resolution further. How do I get better results than I have and a smaller file size. Would appreciate inputs on how to achieve this. Thanks. Renee Yahoo! Groups Links --------------------------------- Yahoo!
