How to upload videos to jotform?

i tried to upload video to jotform so that it can be played at end of form. Also upon end of the video, i need to enable submit button. Until submit button should be disenabled.

If your video is on youtube, then you can use the Youtube widget to display a video on your form. Simply enter the URL of your youtube video and it should be displayed to the form thereafter.

You can also check out our other video related widgets here if your video is not on youtube: http://widgets.jotform.com/category/video

Unfortunately, it is not possible to disable the submit button and enable it upon the end of the video. You will need to use custom code to achieve that, and to add the code you will have to download the full source code of the form.

A possible workaround I can suggest would be to add a checkbox to confirm that the user has watched the video.

Then use a Show/Hide condition to show the submit button once the checkbox is checked. Here's a guide that can help: How to Show or Hide Fields Base on User's Answer.
