Hi guys, I am doing a project where I'm making use of a heart rate monitor. I am able to extract the heart rate data (which is recorded once every second such as: 99, 101, 100, 100, 100, 101, 102, 102, 107, 113 etc).

I am wanting to use this data to make an ECG in After Effects. I know how to make an ECG effect from the tutorials here, but I'm not sure how to add or use the data I have in order to make it accurately follow the data.

Any ideas?

I presume those are numeric values, appearing once a second.

You might have better luck if you could record audio. Then you could use the Convert Audio To Keyframes.

Far less messy and far more straightforward.

Yes that's right the monitor records once every second. Sound would be much easier, but it's only a portable HRM, so it doesn't output any sound.

How about, instead of an ECG effect, just the numbers going up & down (like a counter). Is that possible without a ton of manual work? The data I have is over 30minutes long, and I don't fancy having to manually add 1910 individual numbers lol.

Yes, there's a Numbers effect in AE, which might do the trick. But getting it to display the proper number at the proper interval? Sounds like a job for an expression.

I'd ask about implementing it on the COW's After Effects Expressions forum. They'd have a much better idea of how to pull it off.
