The sofwtare I used to make this video is called Spring. If you fail at googling it, try they keywords "TA Spring" or "RTS Spring". You can download it
here for free. The key to start recording a vid is Ctrl F10. Or is it Alt F10? The only drawback of using that software is that it doesn't record sound. Use something else if you need the sound.
Make sure to run settings.exe and turn all the fancy stuff on (ground decal, rippling water, shadow, etc..). Then play, replay, watch, add AI, cheat or whatever it takes to have some good action. Once you feel ready for tapping, remember remember to use the F9 key to remove the health bar, and the F5 key to remove the interface. Many good Spring movies have been ruined by the cameran forgotting to toggle off health bar. Then, the trick is to hit the Ctrl F10 key. Or maybe it is Alt F10, I cannot remember.
Well, I admit first time I tried that on that new PC, I realised I had no good codec (I'm playing all my videos with VLC.exe). So I just ran some old DivX installer, so as to get a codec with proper compression. However, I feel confident that you're leet enough to have 42 varied codecs already installed on your rig, so this step is probably useless for you. Yet, after pressing Alt f10, or Ctrl F10, please choose a fairly standard codec. I'd recommend DivX or XVid. However it depends on whether you prefer other people to actually be able to see your video, or if you enjoy more insulting them for not using the same ultraleet highly advanced codec as you.
I replayed the same replay, with fast forward to 24min, several time, to get a good grasp of what interesting event there were to film, so that I could shoot them in a single long take. Well, save that not, and I ended with two DivX movie to merge into one. I asked which program to use to cut and glue movies to the same person I regularly ask such question, and was replied, but anyway I already knew, to use VirutalDub. You can download it
here for free. I think this is the answer to the question you were asking, however, I couldn't reply directly because it was the first time I ever used VirtualDub, so I can't act like if it's a program I knew. Beside you're a poster on the forum of the open source remake of some obscure nerdy game, so I take it for granted that you know your way around the net, and as such should be able to google or
wikipediate your own answers. LoL that list doesn't even mention VirtualDub. I guess it was "
marked for speedy deletion", because it was "
not notable". LoL, wikipedia is made of phail.
Make sure you have uber processor and uber memory and uber hard drive whenever you tamper with video editing.
Oh and lastly, don't ask me! Ask people who actually know how to make Spring movies, like, I don't know, Cabbage.
