It appears I need the ffmpeg coding tool. Can you recommend one? thanks

Since I'm using SU2014 32bitwindows, Twilight seems to recommend getting a ffmpeg encoding tool - I found https://ffmpeg.org/
Does this look right? thanks for the help.

FFMPEG is not a format. It is the tool. We have information about it here: viewtopic.php?t=5433

Did you even watch the video? It describes everything you need to know. See also the YouTube description of the video for links.
See video starting at 6m40s
Did you read the link I posted above?

Yes, ffmpeg.org is where you download the tool.

i'm real good at animation but i always get held back because my computer renders real slowly like 2mins per frame(30frames per second video)is there a way to render faster without having to use less figures and taking down my level of animation

2 mins per frame is not bad, actually.
20 mins per frame would be difficult.

To reduce render times, first would be to get a much faster machine. Or render parts of the animation on multiple machines.
If this is not possible, please try these tips:
  • If only camera is animated (it's a fly through animation), make sure your Animation method is set to Only View and that 'Reuse Lighting Information" is checked.
  • Big texture sizes. A lot of models available for download have ridiculous enormous textures. While it's tempting to go big, you are killing your render time. Usually we can go much smaller than we think, even down to 128 or 256 pixel images. Use the lowest resolution you can for each texture that will still look good. Each ray which must be traced throughout the scene has to be checked against each texture pixel that it touches, so reducing this calculation is fast and simple. Use Twilight V2>Diagnostic to find quickly all the texture sizes in your scene and so you can know which need to be reduced.
  • Lights intersecting geometry. Be careful of your light radius and make sure it isn't colliding with geometry. Remember that the light radius only affects the softness of shadows, it isn't needed to make the light brighter. If soft shadow is not critical in the scene, disable all soft shadows for all lights to render much more quickly. The soft shadow takes a lot of time to anti-alias.
  • Bright lights - lights that are too bright will need "error correction" which takes the engine time and so be sure all lights are correctly powered - use "exposure" to correct the brightness of your image, instead of using brighter lights.
  • White or Black or fully saturated colors - Start with the assumption that any "Pure White" surface in your scene should be no brighter than 90% grey. Any "pure black" surface should be no darker than 10% grey. This is true in real life. Make sure no colors are purely saturated above 90% brightness/saturation because this is not physically possible. These will cause a slow down in rendering as the engine tries to compensate for the errors from the colors.
  • Certain materials are time consuming. Metal and Brushed metal, SSS, translucent, and some others tend to be slow to render. Avoid them, use clever "tricks" to "appear" like there are translucent materials - such as a "Fake emit" light emitting material on your lamp surface - turn off cast shadow for that, and any material you don't want or absolutely need to cast shadow.
  • You put your light behind glass. In the effort to model a realistic light, sometimes people put lights behind glass or a translucent surface. This will absolutely kill render times. You should never do this for animations unless you are modeling and rendering a product shot of a light fixture itself. Use the trick above with "Fake emit" and cast shadow off.
  • Insufficient light. If you are using the Interior presets, there isn't really a limitation on the number of lights. So your render will actually go faster if you have more light (which is pretty much true across the board; dark scenes are slow).
