When MP4 won’t upload to Facebook, there are many causes. It could be a problem with Facebook's server. It could be because your MP4 video is encoded with a format that Facebook doesn't support. It could be caused by slow internet connection. In part 2, we will show you how to fix MP4 video not uploading to Facebook issue.

Part 2. How to Solve MP4 Won’t Upload to Facebook?

There are somes reasons causing MP4 not uploading to Facebook. You can check one by one and then use the solution we provide to solve the issue.

Way 1. Convert MP4 video to meet Facebook’s requirements.

• Facebook only accepts MP4 videos encoded with MPEG4, H.264, or DivX codec.
• The maximum length of an uploaded MP4 video, and the maximum file size should be noticed before uploading to Facebook.
• If you want to upload 360 videos to Facebook, the maximum length of a video is up to 30 minutes and the maximum file size is up to 10GB. And the video codec should be H.264.

Although we already know that Facebook supports MP4, we also need to check if your MP4 video exceeds the length and size limit that Facebook sets. You're not allowed to upload a video longer than 240 minutes and larger than 4 GB/10GB. If your MP4 video is too long to upload, you need to trim or split it. If it is too large to upload, you should reduce its file size. To make MP4 video shorter and smaller, you can give Winxvideo AI a try.

If your video neither exceeds maximum length limit nor exceeds maximum file size limit, you need to check your MP4's encoding format using MediaInfo or something you like. MP4 is a container format, so it could be encoded with any codec, such as MPEG4, H.264, and HEVC. Not all encoding formats are supported by Facebook as we have mentioned above. For all we know, Facebook supports MP4 videos encoded with MPEG4, H.264, and DivX. If your MP4 video is using other codec formats, you may need to re-encode it. Re-encoding can also be done with Winxvideo AI.

Now let me show you how to trim, compress, and re-encode video to meet Facebook video upload requirements.

Step 1. Download and install Winxvideo AI on your computer.

Step 2. Launch Winxvideo AI and click + Video button to load the MP4 video you cannot upload to Facebook.

Step 3. When the Output Profile window appears, scroll down to Facebook Video, and choose an output profile. There are four premade profiles, including MP4 Video (MPEG4), MOV Video (MPEG4), AVI Video (DivX), and FLV Video. Among them, MP4 Video (MPEG4) is recommended. After choosing output format, click OK to confirm.

Step 4. If you need to trim your video, click the Edit button, hit the Trim tab, check the box of Enable Trim, and then drag the sliders under the preview window to move to desired start and end positions.

Step 5. If you need to shrink video, you should click the setting icon to lower resolution and bitrate.

Step 6. When you finish all settings, just click the RUN button. Then Winxvideo AI will start processing your video and deliver a new MP4 video that should be uploaded to Facebook successfully.

If you still can't upload MP4 video to Facebook, try the following fixes.

Way 2. Check if there's a problem with Facebook.

You can go to Downdetector and the like to check if there are Facebook outages reported. If there are, you can wait and try uploading your MP4 video after Facebook server's problem is solved. If there are no problems at Facebook currently, move to the next step.
