I created a page on Facebook. It looks like I can only add 100 videos. Is that true?

Yes that is True there is a Limit

There isn't a limit on how many videos you can upload.

Here are the limitations:

- We support almost all types of video files, but recommend using the MP4 format.

- Resolution should be 1080p or less.

- We support file sizes up to 10 GB, there may be longer upload times associated with larger files on slower Internet connections.

- Videos must be less than 240 minutes long. The longer your video is, the larger its file size will be. This may affect the quality of the video and the time it takes to upload.

- We also recommend Stereo AAC audio compression with 128kbps or more.

I don't think there is a limit to the number of videos you can upload to Facebook. It's like other platforms, you can upload as much as you can.

You can upload videos with unlimited bitrates, up to 1 Gigabyte in size. The max file size and time length, though, are 1.75 GB and 45 minutes. But if you go beyond a 1 gig file size, then you must limit a 1080 HD upload file to a max bitrate of 8 Mbps, and a 720 HD file must be limited to a max bitrate of 4 Mbps.
