Hi,

I'm new in this field so forgive me for any stupid questions...

Anyway I have recorded my desktop with recordmydesktop which gave me ogv format.
I have edited it with kdenlive, added some stuff now I want to resize from 1600x1200 to 640x480.
I need the best possible quality because the text must be readable (for youtube).

What ever I tried, from worst to best bitrate, it gave me only blurred videos.

any tips on that?

thanks!

YouTube won't treat anything as HD unless it has at least 720 lines. I don't know if it will work with anything other than 1280 in that case - requiring the 16:9 aspect ratio - or whether a 4:3 960x720 will do.

See http://www.google.com/support/youtube/bin/answer.py?answer=132460&topic=16612&hl=en-GB for file format recommendations

I think, the problem is your video in ogv-format. My videos are mp4-files. And it is better to use the best quality, you can provide. 6000k bitrate, 8000k, or so, 2 pass and so on. And don't resize it to 640x480.

Youtube decodes and encodes your videos another time. Also: It takes some time (about 30 min) until the videos are ready.

I used ffmpeg to convert to avi format and quality is better now.

Thanks!
