Streaming Question

Technically you should be able to stream 720p on 2Mb/s anyway, since Stats for Nerds shows about 1-1.5Mb/s usage on Youtube for it, but I think shaping plays a role.

This.

If you're getting 720p at 1-2 mbps then it's having the crap compressed out of it and the quality will not be at all good.

Nope it's really good quality. Point me to any 720p video & I will test it.

Yip, a high quality 720p stream will use ~1.6Mb/s

Duh

Nothing mentioned about 720p in original post.

That goes against everying I've ever experienced.

Netflix 720p goes at around 4mb/sec

According to that link, it's 2.4Mb/s.

Compressed quality is good too. Watching the rugby on ITV HD on Kodi looks amazing too. I don't care if it's compressed, only about what I see.

well this is the question im asking, because i tested a 3G sim not LTE normal 3G, i went below 1mb/s, and it still streamed fine off the SKY sports HD channel on Kodi. so im going to guess that even if its compressed, the quality wouldnt be that much affected. Which is why i want to know, is a fixed line more prone to buffering issues than say a 3G signal, or would it be the other way around?

In my experience

On Youtube
2meg = 360p - 480p
4meg = 480p - 720p
10meg = 2x720p simultaneously or 1080p

On twitch I get different results
2meg = not working-mobile-low
4meg = mobile-low-medium
10meg = medium-high-source

With Supersport app but i think it has issues with the amount of people streaming at a time.
2meg = never tried
4meg = jumps between 480p and 720p
10meg = jumps between 480p and 720p

Netflix
2meg = it buffeted all the time
4meg = it ran fine at 720p but occasionally dropped to 480p
10meg = runs netflix at 720p and youtube at 720p without a problem.

These are dependent on how the line/isp feels like behaving on the day.

Why is it that you need 4Mb/s for 720p on Youtube, and I only need 1-1.5? Is there something different on your side?

 

[Icemanbrfc]

would the youtube videos in 720p not also be short clips, meaning that the size of that 720p video is alot smaller than say a 720p movie?

The video would still buffer. And it's the download speed per second that matters, not the total length.

The length of the video has nothing to do with it, a 10hr video will stream the same as a 2 minute sample of that same video. It's about devilivering a constant stream without dropping frames, maintaining a decent bitrate.

You can buffer a 2 minute sample in say 45 seconds, but to build up enough of a buffer for the 10 hour video will take a LOT longer.

Go start a 10hr gta v stream (or any other) on youtube and see how long it takes to buffer, no different from a short clip.

The aim is not to buffer at all, or just for the initial second or so it needs to actually load the video, and no more after that.
