I am publishing modules containing videos integrated from Youtube, and these videos turn out blurry on Mac devices. But.. not all of them. And only the first 10 to 22 seconds. I integrated them all the same way (video from website with embed code) - out of 9, two modules are fine, the rest are blurry up to 10 - 22 sec.
Any ideas on what is wrong? I use 1000x600 slide size and I embedded them the same size. The rest of the module looks fine. It looks fine on my PC too.
Since the video is being fed from YouTube, I'd assume that it's just the initial stream and it adjusts to the bandwidth. That happens to me often with YouTube videos while viewing on YT. Its seems to start in SD (which isn't as crisp) and then pops into HD. That would be my guess.
That's what I thought at first, but then I realised that the video always stop being blurry at the exact same second every time. So if a video was blurry the first 11sec, it stops being blurry at the 11 sec every time we tried. Not one second more, or less. Would it do this if this was bandwidth related?
I tried to embed the video so it would start after the blurriness 'episode' (so in this example, the video was set to start at 11 sec.) and it's good and crisp. No blurriness at all. I feel that would not be the case if this was bandwidth related. (and obvs the videos are super clear on the same device when watched directly on Youtube).
I don't know what to offer. The video is coming from YouTube and is embedded in Storyline. There's nothing SL is doing to the video.
My understanding is that YT down samples the video based on the network speed. I would guess that it initially sees a lower speed and down samples, and then the network speed adjusts which in turn changes the video quality that is streaming.
You can contact our support team to see if they have a smarter answer since I'm not a programmer and making broad assumptions, but I assume it's a YT issue and expected behavior based on how the video is being served.

I'll try - thank you!
