I’m not sure if this will help, but there is a free cell animation package called Animation Stand by linker systems. It has everything their pro version does but with ouput limited to a very small resolution.
It does have a built in exposure sheet with the ability to synch audio and mouth shapes and I think you can export or print it, not sure. It used to work with Magpie, but it’s been awhile. You can also coordinate on the 1s, 2s, 3s or what ever you are using.
Problem is, it’s an entire cell animation package and may be overkill for what you need.
