Uploads are limited to 5 MB per MP4.
Finished BAX will be limited to 10 seconds at 30 fps.
You can choose to get the stacked MP4 and make it into a BAX file yourself by checking the box.
Files will be deleted after 15 minutes.
If the BAX file is over 32MiB it will not work, I suggest you compress the MP4 yourself in this case.
