I have in the past made some demos for youtube, but I would prefer if I could use my Mac to make them, since the PC that I have been using is kinda old and therefore I don't get the full 35 frames in some parts of some demos. Is there a good way to do this? I would prefer to use freeware/open source if possible.
Yeah, natt wrote a cool system for capturing completely smooth videos from PrBoom+ even on crappy systems; you might need to play with some lag, but the output video should be perfect regardless, if that's what's important to you.
I only played around with the feature a little bit, but I think you just run with the -viddump parameter, more or less. The usage.txt file distributed with PrBoom+ should explain it all properly. It might be worth looking into.
xit-vono said: I downloaded the newest version of prboom plus (the file says created 12/25/2009), but when I use the viddump parameter, there is no file there or any evidence that a video was recorded.
Have you downloaded all the other files needed for it to work?
(MKVToolNix, OggEnc, x264)
Thanks a lot kimo. But there wasn't any dll's in the mkvtoolnix zip file, is there? I still extracted the files into the prboom+ folder and tried to make a video and it worked. But, while the video was being made, the demo was playing back very slowly, is that normal? The video played back fine though.

My bad, these dlls are only needed for the older version and they're packaged with the older version.
For the newest version that I linked to, you only need mkvmerge.exe

The video and sound are encoded as the demo is played, so the process can be slow even on a fast computer. But, regardless of how fast the encoding goes, the resulting file can playback at full speed with perfect sound sync and no dropped frames. Note that while you can watch the demo as it records, you will not be able to hear any sound.
And btw it also says in usage.txt
Music recording will happen as long as you are not using the SDL or Portmidi music options.
If you want the music with fluidsynth to sound like SDL which uses Windows' General Midi, I've converted it to a soundfont and uploaded it here
Put gm.sf2 in PrBoom+ directory and change the snd_soundfont variable in the config file to "gm.sf2"
I intended to get the most recent version of prboom plus. I did a google search for prboom plus, then followed the link and went from there. The files say that they were created in 2009, but the history txt file goes up to 22.214.171.124
Hmmm, I tried to upload my mkv the second time and it worked. We'll see if there are any problems in the future. Perhaps Youtube changed the way they process videos or something, or else maybe there was a glitch earlier.
Hi, as you can see, I have been using this feature. I uploaded es08 to youtube, but there are some video problems that I didn't notice right away. I checked the viddump file and it has those problems too. Also, I tried converting pt08 to video, and that one has video issues too. Anyone have an idea what causes these?
