Converts time based data sources to Adobe's mgJSON format (Motion Graphics JSON).
A live version of this app can be found here: To mgJSON
The first iterations will be very limited in terms of customization and supported formats, but the provided parser funcs can potentially be adapted to any source that associates time with values.
For instructions on how to use mgJSON files in After Effects, see Work with Data-driven animation
See the sample_sources directory for compatible samples.
The simplest CSV file supported is a column with numbers. When a frame rate is specified, every value will be assigned a time based on the frame rate. Optionally, a header can be included in order to label the data. If the desired times do not correspond to the frame rate, a left-aligned "milliseconds" column can be used to specify the times relative to the beginning of the video. Additional columns with different labels can be appended to the right-hand side of the document to create new streams.
GPS tracks with time fields can be parsed. For now, only the first track of a file will be read. Based on the parsed data, additional data streams can be computed (speed, acceleration, course direction, distance...).
src, _ := ioutil.ReadFile("./sample_sources/multiple-data.csv")
converted := FromCSV(src, 0)
doc := tomgjson.ToMgjson(converted, "Author Name")
f, _ := os.Create("./out.mgjson")
f.Write(doc)
f.Close()See all_test.go for implementation examples.
You can find sample After Effects projects that use mgJSON files on the GoPro Telemetry Extractor page. Look for the Lite/Trial templates.
If you create something with mgJSON, let me know and I'll add it to the list.
These apps can output mgJSON files:
Please, make your changes to the dev branch, so that automated tests can be run before merging to master. Also, if possible, provide tests for new functionality.
- Import from json and other formats
- Enable creating static fields? Non interpolable fields? Multidimensional fields?
- Fully understand legal min and max. It seems if extreme values are used and their JSON formatting looks as an integer, AE limits the range of numbers it can display. For now it seems safer to just reuse the occuring min and max
