To make a video post:
On the web: If it’s on Vimeo, YouTube, or some similar site you can just open a new video post, click the globe icon, and paste its embed code or video link into the post form. You can also click the camera icon to upload your own MOV or MP4 files—up to 100MB and 5 minutes per day.
On mobile: You can post videos in a couple of ways. You can:
- Open a new video post. Then pick a video from your camera roll, or record a new one.
- Insert a video when making any type of post, simply by tapping the video camera icon and then taking or selecting your video.
- Paste in a link from Vimeo, Youtube, or a similar site to embed the video directly into any post.
- You can add a filter to your video if you're it using the Tumblr app. Just tap the disco ball icon, and swipe left and right to preview and select a filter. Then start shooting your video!
PS: No judgment there but a friendly reminder that per the policies you agreed to when creating an account, we don't allow uploading sexually explicit videos of any kind to Tumblr.
