ajobbins: Isn't sport generally 50hz at source?

Depends on where it's coming from .  Japan will be 60 fps.

Is the framerate variable to the source? With Kayo here in Oz, 50fps sport looks less smooth with my Android TV set to 60hz. If Spark are sending 50fps source content to viewers at 60fps, isn't that going to bake in some of the unsmoothness to the source stream?

Hi, frame rate is normally dicated by power supply frequency, this assists with mitigating lamp flicker rates screwing with shutter/frame rate. This was more an issue in days gone by, and more a problem with capture, and not so much an issue with playout in this day of modern type displays as opposed to CRT's

I look forward to testing it on F1 this weekend.  I ran an older F2 race and could easily see the framerate issue so now have somethnig to compare against, as well as sky sport via Kodi.

I'm genuinely still trying to feel the love for Spark Sport but they're not making it easy.

Having found out this week my (LG) TV isn't going to get an app I was actually totally OK with sticking with my Chromecast Ultra now it's going back to 60fps. Another positive being they're now chucking in the odd boxing fight night (well twice a month so far, in line with F1 races at it's busiest part of the season) on top of the EPL and F1 which I follow.

So my email to them was a quick congratulatory:

1) Awesome news on the 60fps. 

2) Thank you so much for the boxing, an added bonus which wasn't expected, which I'm sure will pull in more subs!

3) Why not look at adding a boxing sub-category, like you do for everything else you show, to increase visibility?

So at this point, after months of issues, I'm actually praising them for their progress. To which I got back the response (verbatim):

"Hey **,

Thanks for getting in touch.

Unfortunately we do not offer this , Thank you for your feedback though and glad you have picked spark sport!

If you want to ask about the same question or give more information, it’ll make it heaps faster for us to help you out if you could reply back to this email. 

Regards,
**"

Whilst I'm sure my nimble fingered friend will get great scores for the email queue they're clearing it seems a shame they still can't communicate. I'm hoping it's not the 60fps they're saying they don't offer?

Spa FP1 in 50 fps goodness 😃

Looks fantastic - great job SS!

(watching on HTPC/Firefox)

Yep on the browser it looks much nicer and chrome is reporting a 7mbps stream bitrate.  Has a new Android TV app been released or is the code adaptave enough now to stream the right one depending on device?

Its the viewing not the capture that matters. When TV was invented there was no shutter at all, just vidcon tubes being scanned out at whatever frequency they ran at. Problems came with the mains power supplies in displays being crap and locking the sync to the grid power meant that it was going to be static bars and distortion rather than a rolling mess. Also Japan has a split 50/60Hz grid based on regions, but use 60 for all their broadcasts.

"shutter" in cameras didnt happen until CCD sensors, and then it was just luck that things were made in the same framerate that they were consumed in that it was OK with lighting, but you still get bars appearing with rolling shutter like every damn camera made since the 1990s seems to have. Under crap fluro lights with a mobile phone its usual to have some flickering bars when videoing when it steps the shutter speed down because it is bright. You also sometimes see that with the slowmo replays on sports since they are sampling at more than the line frequency so the lighting in the stadiums will usually flicker up and down in brightness during the slowmo playback.

Looks good so far on my Samsung TV app.....

1080p-60fps-7000kbps-init.mp4

720p-60fps-5500kbps-init.mp4

is a couple of things i see via the webbrowser

Yes nice, and looks like they also plugged the exploit that enabled free viewing of ALL spark's content since day 1..

uh oh can of worms just opened
