The problem may be the site and how it handles larger MP4s. If you can, you should consider starting a YouTube channel, loading your videos to that, and posting a link here. Your video will show up in your post, and there will be no buffering issue. I know it's an extra step or two, but there are many advantages. The primary one is being able to retrieve the video easily if you see the opportunity to post it in the future. The other advantage is that you have a permanent and personal archive of your work. You do a very nice job with your videos. They are worth some extra effort to save them. 

@marty-johnson Xfinity has up to 230 MB upload speeds for the service I pay for. 

Here is a photo of a speed test I just ran to post in this thread:

As you can see the download was 932.51 mbps and the upload was 234.91 mbps. Xfinity just upgraded their internet for certain plans to have the 230 mbps upload speeds in the last few months. 

@jkuvakas I had a YouTube account but it because a pain trying to upload the photos, google and Apple don't always get along well with each other. I had a bunch of videos of 1/18 scale cars and they disappeared so I gave up on that, Rumble works ok but you don't get a clean link on this site with Rumble videos so you don't have the video showing.

I had a YouTube account but most of my videos were deleted from it, they just disappeared one day. YouTube/Google and Apple don't always get along real well with each other while I can view YouTube videos on my Apple computer my uploads can be a pain in the rear. 

@john3976 - Regarding that 234 Mb/s upload speed....

WOW!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
