    It depends on the quality of the video you have selected. If you've selected 720p or SD in settings it will look pretty bad on a big TV. 1080p will look better. The Apple TV looks even better again because it's doesn't compress the signal like the AV adaptor does. However, it's not a huge difference, you should be able to make it look really good with the equipment you have.

    Are you sure you are using a genuine Apple AV adapter? With a fake one I can confirm that the quality is pretty bad, I'm using it on a small screen so I can imagine the quality on a big screen. I'll have a genuine Apple adapter for this week end so I'll be able to tell about the quality difference.

    I just tried the genuine apple av adapter and it look a bit better than a fake one. But you still don’t have the feeling of a fullHD video because of the video being streamed by the AV adapter. Apple TV should give equal result as the original filmed video.

    The true problem with this platform is the video compression which is very bad.  They compress the hell out of the videos with codecs that don't handle motion very well in order to save money on streaming costs.  Even if you have the very best hardware, internet speeds, 4k, etc, the video will be grainy and blurry for this reason.

    That's a lot of assumptions wilsonjeff72

    To the best of our knowledge, we the same H264 codec that Netflix uses for most of their content. We also use a higher bitrate than they do (22Mbit vs about 16) However, we run into several problems that movies don't. First, our starting point is a GoPro or similar. Movies start with hundreds of thousands of dollars of camera equipment that won't fit on a bike, this gives a much better starting point. Second, the way video compression works is it "saves" the un-moving part of a frame for several frames and just replaces the moving bits. This is great for most scenes in a movie, but terrible for moving along a road. 

    We're looking at providing a higher bitrate version (tAround 50mbit), but it's not something that most of our users internet or storage will be able to cope with. The infinitely variable playback speed of FulGaz prevents us from using HLS, which swaps out to a lower bitrate if the connection slows. 

    If you are an expert in this field and you can make some suggestions, we are happy to take them on board and experiment some more. From our research this year, H265 is worse at the same bitrate than H264 for what we do by the way. The other codec of promise is AV1, but this isn't widely supported yet.

    Mike, I made no assumptions above.  These are simple facts.  More compression = smaller files = cheaper to stream and no amount of horsepower or bandwidth on the client side can magically reverse the loss caused by your compression.  You know this.  

    I just downloaded and looked at one of your 1080p videos (1000-island-parkway-short.mp4) and the video bitrate is 6631kbps (6.6Mbps).

    I downloaded and checked a couple others and they're both under 5.5Mbps.

    amy3.mp4

    banff-4k.mp4

    Can you please provide a list of the videos with the higher 22Mbps bitrate compression?  Even better, if you add the bitrate to the thumbnails then we know what rides to pick if we want to ride the best quality videos you're offering. 

    Is there any consideration given to re-encoding the lower bitrate videos to increase their quality?

    We extracted your preferences and you've got you video resolution preference set to 720P. This means even if the ride is available in 4K, you will download the 720P version. The same applies if you choose 1080P as your preference. The 1080P versions are a lower bitrate than 4K. It has to be like this so people who don't want the best quality can stream, download and store more rides. 

    To solve your problem on the Apple TV, go to settings and set the resolution to 4K. You will then only see the rides available in 4K (it also has a small logo on the thumbnails). Banff is 22Mbit in 4K, I just downloaded it and checked it myself. 

    That should give you a much better FulGaz experience. 

    There are no plans to provide higher bitrate versions of lower resolution rides. However, there are a couple of hundred new 4K rides on the way.

    Yes I had changed the setting to 720p the other day in an attempt to prevent the streaming from continually freezing (which did not help).  This issue is so bad lately I've lost all confidence in even attempting to ride FG while streaming.

    Please skip the obvious suggestions.  It has nothing to do with my setup.  Nothing has changed in a year here.
