As I have done things on gens+ and whatnot, I have stumbled across a website called youtube. Seeing my chance to sho- I mean share my videos I joined. I have watched vids of SM and G199. My question or you is simple. What program did you use to change the file type/what recording method did you use?

<_<
>_>

Peanut butter.
<Sondow> also what

For my 3D videos:

Using a TV tuner card, I plugged the yellow composite cable into the card, and converted the red and white audio cables to a 1/8" stereo connection and plugged that into the soundcard.

The built-in ATi MultiMedia Center program that came with the card has a TV window that you can pop up on demand to watch TV from your computer screen.  It also lets you take snapshots of the screen, as well as--importantly for my purposes--record the stream into a video file.

So as not to cause lag on the output by forcing an encoder to run in realtime while I'm playing, I record my videos in raw 320x240 30fps mode.  This takes a LOT of disk space--almost 300MB per minute--but with a big enough hard drive, it won't be a problem.  Press record and start playing.  If I don't get a successful run after about 10 minutes, due to the huge potential file size, I stop the recording, delete the file, and try again.

After I get a success, I open the raw file in Avidemux.  There I trim out the unsuccessful parts of the run, so that what's left is the life or lives on which I achieve success, and nothing more.  I save the resultant file by simply copying the video and audio bitstreams for the frames in question.  This file is still 300MB/minute, but because it only contains the success, it's fewer minutes.  I keep this file for archival purposes and delete the original larger file.

Obviously, if even a 45-second video takes up 200MB, you can't expect anyone do download that.  It's compression time.  If the run is discontinuous (such as a hunting stage with lives cropped out in between), I construct a title card.  Currently, the title card variation as seen on Security Hall m5 and others is the most prevalent of mine, and I used that from April 1, 2006 (Security Hall m5 0:18.97) to January 11, 2007 (Sky Deck Knuckles 0:06.69).  The title card variation as seen on my current Death Chamber m1 run (0:08.67) is the one I'll be using for the foreseeable future.

Avidemux can produce compressed videos as well, so where possible, I use it to encode the video with x264 in two-pass mode (usually around 400kbps).  Audio is encoded with LAME at 96kbps CBR, with the volume reduced by 10 decibels (you wouldn't know while playing, but the TV program records videos with the sound really, really loud.  This also overflows the sound channels, so that higher frequencies are gone from the video altogether, leaving ugly gaps in some cases, such as the easily-noticeable Final Rush no points or Final Chase all rings.)  Unfortunately, my experience with Avidemux has found that for some reason it can't encode streams comprised of a mix of video files and still images without either losing the sound altogether or crashing.  As a result, when I use a title card, I have to open the video in Windows Movie Maker and produce it as .wmv, with video+audio combined bitrate of 512kbps.

I'm hoping for that Avidemux bug to be fixed, and to find a program in Linux that can record a live stream coming into the TV card (MythTV's "record live TV" mode isn't really live, it's delayed by 2 seconds--clearly unacceptable when you're trying to see the result of your input on the game).  If I can get that much, then I don't really have any further use for Windows.

There are other players that use a VHS tape as an intermediary step, or record a DVD while they're playing and send that to the computer (not to mention the lower-quality video producers who point a camera at the screen and hope for the best), but this is how I do it.

^Although if I may chime in, those lower-quality video producers do get the job done...

Just do whatever you can to get the video produced.  If people can watch it, then congratulations, you've made a video.  Know that to get a vid uploaded here on TSC you'll need to get an admin to give you the privilege, which is usually as simple as asking and maybe having to upload the video elsewhere and link the admin.

As for Gens... Gens+ can't actually make a video file. For that, I use Gens Movie (another modified version of Gens) available at TASVideos. I record the buttons to .gmv and then dump that to AVI; the whole thing's pretty intuitive IMO.

Just make sure you're not using the TAS features like slowdown, rerecording, etc.
<Tails> also "GET BLUE SPHERES" on a black-and-white TV remains the best special stage of all time

<Achlys> wat ave you done!
<Spinballwizard> apparently killed your h key

Ah... now I understand. Thanks a bunch.

Edit: Although, you guys only pretty much answered my second quest-*shot*

I record videos in AVI format from the start, so that doesn't need to be changed.  What does need changing is the codec, and for that I use http://avidemux.sf.net along with x264 fro compression.

If you're recording from a computer, it is likely already in AVI format.  Videos on TSC are largely either AVI or WMV (although lately I've actually been getting better comperssion rates with SWF, I wonder if Rolk'll take that).  Windows Movie Maker, which comes with most Windows PCs, will make reasonably-sized WMVs if your recording is in a format that naturally comes large (MPEG and whatnot).  There's better software out there, but there's no excuse to not have tried scaling the video down with this if you have it (I think it's free on MicroSoft's website if you don't).
