If you are still experiencing issues after following the above process then you may have issues with your internet connection, playback device, or source material.
To eliminate the internet connection as an issue then try changing the network, using a wired connection, trying the upload on another machine, and trying to upload a different file. If it fails in a range of situations then the file size may still be too big, so try a larger RF number is the above guide, or get technical support.
To eliminate the playback device, try playing the video on other devices. If issues occur across multiple devices then there may be a problem with the video file, which may require trouble shooting - get technical support.
To eliminate the source material as the issue, try downloading some test footage, transcoding it using the above guide, and seeing if it will play back. If the test footage works then your source material needs troubleshooting, get technical support.
It may be that the above guide is not working for you, so it may be worth trying an alternative compression tool to rule that out.
