How Do I Get Started?
The Big Things
1) Create a system for student accountability. If students are going to be responsible for instruction there needs to be some check on whether they are following through or not.
2) Focus on classroom time. The key principle is that what students do in class (when a teacher can be involved) should be the most important. Make sure that the most challenging skills are fostered in the classroom with a structure that supports student learning. Both finding and creating resources for students outside the classroom, will be time consuming, but the best resources for outside the classroom will be wasted if what is happening inside the classroom isn't accessible to students and focused on their learning.
3) Don't worry about perfection. Teaching is a process, you wouldn't expect your students to be perfect right away, don't expect yourself to be either. Just keep growing. There will be mistakes and oddities as you go, don't let that slow you down.
Start Small
It will probably help to think first about creating individual flipped lessons. Look for topics in your curriculum where students could get content outside of classroom. Alternatively look for topics where students could research or explore the topic. Consider materials you've already made or used from another source. Could those lessons be modified so that students could use them entirely or mostly independently? My first steps were with review assignments, I found outside sources of the content and gave students access to those sources and a timeline to take advantage along with the practice so I could see how well they were mastering the material.
Remember that flipping doesn't require you to make videos, but when you're ready to make your own content it doesn't need to be a big production. Some easy techniques for video making are just filming yourself at a whiteboard or adding audio to PowerPoint. These allow you to do things that are similar to what you've done in class and will help ease into content creation.
Look Toward the 4 Pillars
1. Flexible Learning Environment
2. Learning Culture
3. Intentional Content
4. Professional Educator

Work Together
If you teach the same course as someone else design together. One of the benefits of flipped lessons is that they can be implemented in a variety of classrooms and shouldn't rely on the teacher the same way a traditional lecture does. Even if you don't teach the same course, consider working together anyway. By creating lessons that can be independent lessons can serve as review for one class and new material for another.
Video Basics
If you're ready to pursue creating your own videos here are some basic "rules" to get yourself started.
1) You are not a big production company. Yes, there are some amazing videos out there such as on flippingphysics.com, but his first videos were video taped lectures. Think growth mindset, do what you can to start and get better as you go.
2) 10 Minutes or Less. Any source that has given a time for videos has given 10 minutes or less per video. Videos are not like class time, if a topic requires more than 10 minutes split it up into multiple videos. This way students are more truly watching at their own pace. The end of one video might trigger a short break for them so they are better focused when they start the next one.
3) Show Your Face. I was surprised too, but students actually like to see their teacher (one of the benefits of making your own content). If you can record your face and include it in the video, you should. Depending on how you film and what else is on the screen it may not be possible, but when you can do. It's fine to have yourself introduce and then get out of the way too.
4) Make Mistakes. No one is perfect when teaching in the classroom, don't pretend you are in your video. If you say the wrong word, just correct yourself like you would in class once you catch it. This keeps the video personal and reminds students that making mistakes is okay as long as we strive to fix the ones we can. Also if you keep shooting until you don't make mistakes, you'll give up on creating videos. I only stop and restart if I make a mistake in the first minute after that I fix it in video and students will either hear/watch the fix.
