I want to be able to convert ppt to video files automatically, without user interaction on Windows. Like convert_ppt_to_video qqq.pptx --screen-size 1024x768 -o qqq.mkv.

How it's better to attain this? What programs should I use?

You should just set the slides to automatically progress to the next slide after a given amount of time. Then, if you have a hypercam (screenshot-like video recorder), record the slideshow. Then crop the start and finish times to your desired times.

OK. Now thinking how to make all this unattended and in background. –  Vi. Dec 19 '11 at 15:04
    
What exactly are you going to use the presentation/video for? –  fr00ty_l00ps Dec 19 '11 at 15:11
    
Playing it on remote GNU/Linux system without user interaction. –  Vi. Dec 19 '11 at 16:13
    
Then my solution should work, because you just want a video that plays without anybody having to do anything, right? –  fr00ty_l00ps Dec 19 '11 at 17:38

Looks like it can be done with PowerPoint for showing the presentation, RDP client for setting the screen resolution and Screen Capture Recorder + VLC to record it to file.

vlc.exe  -I dummy dshow://screen-capture-recorder --sout '#transcode{vcodec=theora,vb=1500}:standard{access=file,mux=ogg,dst="d:/home/fff.ogg"}'
