How to improve output of screencast using command and ogg?

[abcuser]

Hi,
I have watch tons of video on youtube, read several tutorials and I see big mess in changing VLC GUI, so I am unable to replicate any really useful screencast. So I would like to have a "command" to create screencast.

I would like to create a screencast with VLC using command prompt in VLC Media Player 1.1.10 on Windows XP sp3.

I would like to do the following:
1. create screencast using command prompt (I don't want to follow 10-steps instructions that are changing every version of VLC is out)
2. have .ogg as video codec output
3. see mouse icon (I have cursor.png file for mouse icon)
4. have a quality display (to see what is written with font size 12 - now I can't read font size 12)
5. if possible to have a magnification (zoom) where mouse is displayed (to have a font size 12 to see it very clear e.g. like bigger font size)
6. have correct speed of recording (I am getting now to fast moving video).
7. record video without sound
8. record my whole screen (witch is 1024x768)
Thanks

So far I have found out the following:

Code: Select all

vlc.exe screen:// --dshow-fps=29.950001 --screen-fps=15 --screen-width=1024 --screen-height=768 --screen-follow-mouse --screen-mouse-image cursor.png --sout "#transcode{venc=theora,quality:10,scale=0.75,fps=15}:duplicate{dst=std{access=file,mux=ogg,dst=c:\screencast.ogg}}}" --no-sout-audio

Any idea how to improve video screencast? Specially quality of seeing font size 12 objects clearly, correct speed of recording and magnification near of mouse?

P.S. My mouse coursor file "cursor.png":

increase the vb

vlc.exe screen:// --dshow-fps=29.950001 --screen-fps=15 --screen-width=1024 --screen-height=768 --screen-follow-mouse --screen-mouse-image cursor.png --sout "#transcode{venc=theora,quality:10,scale=0.75,fps=15,vb=800}:duplicate{dst=std{access=file,mux=ogg,dst=c:\screencast.ogg}}}" --no-sout-audio

I have searched the web and found vb stands for "video bitrate" and the most web pages have settings of vb=800. I have set this settings and screencast has dramatically improved. Did I set correct value for vb or is there any other value more suitable?
