I'm tired of having to reply to various post about asking for SFM Tutorials, so I'm just going to make a post containing all the playlists that helped me learn SFM.

1. The official SFM playlist by Valve.
2. https://www.youtube.com/playlist?list=PL2B46DEB4157E67C4

This is where it all begins, The best way to learn almost all the basics of SFM is the official playlist on the Source Filmmaker channel. Aside from 2 videos, this is the best video for beginners.

The two videos that are not done well by the official channel are the Time Selection tutorial, and Graph Editor tutorial. They don't teach the most important parts.

1. SFM Tutorial Week #2 - Using the Motion Editor by Argodaemon

https://www.youtube.com/watch?v=OfBfsqwylo0&list=PLmx5NIR6PO5t2vfHIX6GNkpXiFODM_6KJ&index=21

Now, THIS is the ultimate tutorial for the Motion Editor in the Motion Editor. It may be long, but it's well worth it. Argomadaemon's tutorial not only goes over everything from the Time Selection tutorial, but also goes over EVERY procedural preset, as well as overwrite, offset, and transform modes.

1. How to Animate with the Graph Editor by Sir Wade Neistadt

If you're looking to use the Graph Editor, Sir Wade Neistadt is THE go-to. Sir Wade covers EVERYTHING, from how to use the different fcurves in the Graph Editor for moving on a specific axis, to using the thing that makes the Graph Editor more powerful than the Motion Editor: The Tangents. Linear Tangents, Flat Tangents, Spline Tangents, Step Tangents, Weighted Tangents, and Unweighted Tangents.

The tutorial on the Source Filmmaker channel teaches you nothing about the Graph Editor's power.

1. 12 Principles of Animation

https://www.youtube.com/playlist?list=PL-bOh8btec4CXd2ya1NmSKpi92U_l6ZJd

Of course, if you're going into SFM for 3D animation, you have to learn about the 12 Principles of Animation. Squash and Stretch, Anticipation, Staging, Straight Ahead and Pose to Pose, Follow Through and Overlapping Action, Slow In and Slow Out, Arcs, Secondary Action, Timing, Exaggeration, Solid Drawing, and Appeal.

1. Sir Wade Tips

https://www.youtube.com/watch?v=RQ31vjgJM2c&list=PLS4vjlZXZ7f5m5ED4ylJdUPTR5YKEg1bY

Sir Wade Neistadt is basically a completely free college level animation course on Youtube. I've organized his videos into a nice playlist. In it, you'll learn things such as professional workflows, what NOT to do, animation blocking, and how to find reference, shooting your own reference, real world camera tips and tricks that you can apply to your 3D animation, keep alive workflow with how to do a breathing animation, animating weight, lighting tips, some Blender stuff, and even interviews with professional Disney animators.

1. SFM Tutorials by Argomadaeon

https://www.youtube.com/playlist?list=PLmx5NIR6PO5t2vfHIX6GNkpXiFODM_6KJ

Argomadaemon's playlist teaches you a lot about what SFM has, including Depth of Field and Motion Blur, Animation Cycles, Creating an artificial sun light, and more.

1. SFM Tip of the Day by Jimmer Lins

This youtube channel is full of videos for movement reference for animation, whether it's walking, running, skipping, sitting, martial arts, etc.

This is a complete list of all the stuff that goes over absolutely everything you need in terms of SFM, and animation knowledge in general.
