I'm new on Adobe Forms. I'm a teacher. I'd like to know how to insert an audio and/or a video file on a form.
Thanks for your answers.
Audio and Video files are not supported forms types at this time. Forms can be designed to allow the attachment of these types by form fillers, but not as a part of the form itself.
It would be possible if you used a PDF form, but you'd have to use Acrobat to create it and add Rich Media Annotation(s) (RMA), and not all FormsCentral features are available with PDF forms.
