Both options are possible.

Most of the time we recommend adding all clips to one video before uploading it to hihaho, since hihaho is not a video editing program. Also, you can add a table of contents to point out the different chapters or use the jump interaction to skip a certain part.

If you prefer, you can also upload every video clip separately to hihaho. With the Linked video interaction, you can link every clip together to make one complete interactive video. Keep in mind that you have to publish every hihaho video.
