Doodly

This is one of the best video creation tools I've used in a while, it's super easy to use and I can create my own explainer videos in minutes, instead of paying someone else to do it, I'm using Doodly to make videos for my courses and for marketing as well. What I like most about Doodly is
- Ability to upload my own images
- Free preloaded soundtracks for background music
- Ability to upload your font styles
- Custom voice over audio
- No limits over the number of videos, create unlimited videos!

- Internet connection is a must in order to use the software
- The Length of preloaded soundtracks are short, even I couldn't find soundtracks of more than 3 mins in length

The easiest way to create an explainer video. It has a tons of ready-made drawings that you can search for inside the software. Just select the one you want, and the tool will automatically make it as a drawing.

There are a huge amount of assets ready to use, but if you don't find what you're looking for, you can import your own and use the "edit" tool where you can place points on how the drawing hand will make that drawing appear in the video. Honestly, in my opinion, this is the best feature.

Using this, you can use whatever image you want and just tell it how to draw, and you'll have a nice explainer video, with custom drawings, that makes your video unique. This is a lengthier process than normal, since you have to teach the tool how the hand needs to move, but for me, it's better.

The options you have is how fast or slow you want the hand to draw the asset. You can also chose different hand styles, with a shirt, without a shirt, different pen types, and even cartoon hands!

Another great option is you can choose whatever background you want to use. The standard is white, but you can also switch to a blackboard, a greenboard, a glassboard and even CUSTOM - where you upload whatever background you want. This is great if you want it written over a video, or special slides. Again, I like custom the most, but make sure the assets you are using or uploading have transparency for best looking results.

There is rainbow add-on that gives you "colorful" assets, but it basically just gives the option to have those previous characters be filled with color. The color in these assets doesn't have a nice path for the hand to move when filling them up. It just goes to a standard fill, which isn't fancy at all, and looks un-natural to the rest of the drawing. To be honest, I don't even use this add-on and it seems like a lazy attempt to get more money.
There is also no way to mass-add assets that are made for doodly. Over time I got several assets that I've received as a bonus or reward through email, but I just got an archive with image files. Of course I can add these in, but they don't have the drawing paths included, so I would need to edit and configure the drawing paths manually. There are no specific software file types for these types of assets.
You can also buy assets from the marketplace, which I've never done, but I'd expect those to have the drawing paths included in the purchase.
