Voting and Demo Questions

[Glass Joe]

I've got a few questions that I was hoping someone could help me with. I counldn't find the answers in either the forums or the game docs.

1.) How can you call a vote to change the map?

2.) How can you call a vote to change the game-mode?

3.) How can you pause, slow-down, fast-forward demo playback?

4.) How can you record a video file from a demo? What format will it be in?

Thanks.

1.) How can you call a vote to change the map?

"vcall chmap dm_aneurysm" for example

2.) How can you call a vote to change the game-mode?

this one i dunno... should be a "vcall somethingAboutModeChanging"

3.) How can you pause, slow-down, fast-forward demo playback?

"set slowmo value" (1 is the real speed value, 0.1 will slowdown with a ratio of 10, 2 will playback at 2x... even if i didn't ever tried it, i assume a value of 0 pauses the demo)

4.) How can you record a video file from a demo? What format will it be in?

"set cl_capturevideo 1" will start recording and "set cl_capturevideo 0" will stop it. It generates a (lotta) pictures and a .wav file. I would advise you to set the appropriate cvar to get jpeg screenshotqs instead of tga (which aren't compressed)

Question 1 and 2 can be solved with the same vote..
vcall chmap dm_aneurysm
dm is the game type and aneurysm is the map
vcall chmap tdm_aneurysm
would chosse Team Deatchmatch on this map..

slowmo is right.. you can pause a demo with 'pausedemo'
Or if you want easy keybinding take a look into this thread: http://www.forums.alientrap.local/viewtopic.php?p=357#357

scr_screenshot_jpeg 0
will disable using jpg files for screenshots and then tga files will be created. Those are bigger but are faster to create and have better quality which is what you want for movies anyway Do not forget to set it back later again

You can call a vote for another gamemode the same way you vote for maps. Just use "ctf_basementctf" as mapname for example.

4.) How can you record a video file from a demo? What format will it be in?

"set cl_capturevideo 1" will start recording and "set cl_capturevideo 0" will stop it. It generates a (lotta) pictures and a .wav file. I would advise you to set the appropriate cvar to get jpeg screenshotqs instead of tga (which aren't compressed)

I recommend:

Code: Select all

cl_capturevideo_rawyv12 1
cl_capturevideo_fps 25 // or 29.97 if you are using NTSC
cl_capturevideo 1

That will record a raw YV12 stream (uncompressed, so it will get quite large, but best quality), which mencoder can convert to XVID or OGG/Theora for example.
Btw: it doesn't matter if your framerate drops below 25 while recording, as of Nexuiz 2.0 the engine will still record every frame (recording will just take longer) and keeps audio synced.

Kadaver is right, as usual.. If you wonder, rawyv12 is a video format used iunternally in lots of programs, not mane programs can read it directly, but using the method kadaver describes here, you can save yourself _lots_ of work.

If you are really keen on making things really good you could also set the resolution of the game to standard pal or NTSC resolutoini before capturing, so ytou dont have to resize later. You should also record everything on _half_speed_ and the double the speed of the playbak in an editor (if you are going to edit) cause it looks better

If you are only making short stuff, ignore all I said

ok. now i have file

"movie11.yv12" (size 250 MB, lenght 20 seconds ) and i can't run it or convert it to avi file (i use windows XP). How can i ( pls easy kind) do this?

(i always use search in forum and google before i ask)


-------------------------------------------------------
i try to use mencoder (i have read manuals) but somethink is wrong

i try this:

Code: Select all

mencoder.exe movie11.yv12 -o film.avi

and i see this:

Code: Select all

You forgot to read the mencoder manual

Code: Select all

mencoder.exe movie11.yv12 -o film.avi -demuxer rawvideo -rawvideo w=640:h=480:fps=25:format=yv12

You might need to change w, h, fps for your configuration.

Is it possible to record stuff as some sort of a script and then dump the video upon replay?

If I want to dump a 1280x1024 (HDTV/bittorrent you know) session uncompressed, I better do it that way .

Recent mencoder command:

mencoder dpvideo002.yv12 -demuxer rawvideo -rawvideo w=1280:h=1024:fps=25:format=yv12 -o film.avi -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=4096:aspect=1.33333

Just record a demo and capture the video while replaying the demo.

You mean scripted camera movemnt or maybe scripted bot movement? Hmm Possible but it would be much coding work..
