The video has plenty bitrate. That might actually be the problem. 1808 mbps is way too much. A more realistic bitrate would be around 12 Mbps according to YouTube. A high bitrate can cause several problems:
1. Because the bitrate is high, the amount of data that has to be read in a second is large as well. This means that if your hard drive isn't fast enough you are going to have a hard time.
2. Clearly, YouTube can't serve files that are this large. Storing them and broadcasting them is a real challenge. If the file you upload is too large, YouTube is going to transcode it. This transcoding can be quite poor sometimes, like in this case. You are better off choosing a lower bitrate.
Hope this will help.
