Gear 110 can't handle 1080p + instant replay?

I have a Gear 110. Last year I streamed at 720p with no problems. This year I've tried a few streams at 1080p (around 6 mps--can't remember for sure). CPU shows low 40s%, but whenever I try to do an instant reply, I get quite a few dropped frames. 

Is this normal for this processor? 40% doesn't seem like it should be stressing the computer too much.

The computer is well past the warranty. If a CPU upgrade is possible/recommended, what would be a good upgrade to handle this workload?

  • CPU seems low so that, in and of itself, isn't an issue.
    What version of Wirecast are you on?
    Are you also doing any ISO recordings and, if so , what Quality setting?
    Are you recording to the internal drive?
    How full is the drive?
    Is Wirecast reporting dropped frames (number increasing) when playing  the Instant Replay shot or is this just a visual assessment?

    tested again today and 1080p 60 at 6.8Mbps was just too much for both my 110 and a custom build computer (3 years old now, but top-of-the line at the time).

    When I set the Video Display rate to 60 fps (to match encoded settings), the CPU jumped up to 65%-70%.

    When I go to 1080p /30  4.5 Mbps, it's fine, so I guess I'll just go with that.

  • Last year I'm sure I was using x264. This year I was doing the same, but upped things to 1080p. Lots of dropped frames on instant replay, so I dropped down to 720p, but STILL had dropped frames.

    A few days ago I changed to Intel Quicksync, and with that setting I can go 1080p with 0 dropped frames on instant replay. Not sure why things have changed -- I thought x264 was supposed to be 'the best'.

    Anyway, things are working fine now with Quicksync at 1080p, 30fps, 9,000 mbps.

     Quicksync uses less CPU resources than x264 so that may be a factor.

     Depends on the needs. Quicksync can be more efficient. You can change x264 Quality setting for lower CPU use but that lowers quality. Quicksync may be the better option.

     Good to hear it's working. Quicksync is best for your situation. After all that's why we offer the choice. Quicksync certainly can be the best choice.

  • Actually, this worked for a very short time, and ever since, instant replay has been dropping frames again. CPU is in the low 20s, and bandwidth at both schools were I stream is very robust. On Thursday, I had a few 1000 dropped frames total, but only did a handful of replays, so I'm guessing it was also happening when using my graphic overlays (I never watched the dropped frame counter during that time).

    I know that I am using a higher bit rate this year than I did last year, but with the CPU% so low and high available bandwidth, I don't see why this should be happening. I have even dropped down to 720p and 4.5kbps and still get dropped frames.

    What changed then?
    New graphic overlays?
    New monitor setup?
    What is your upload bandwidth (tested, not claimed by the ISP since they can have problems)?
    Try doing a local only recording using Quicksync.
    Is this only when using Instant replay, recording? playback?

  • I AM using new graphic overlays, but using the same file format/settings as before, so I don't see how that would be causing the problem.

    No new monitors.

    Bandwidth at the last game was 80 Mbps up (320 down) -- tested.

    I haven't tried recording anything this year.

    CPU was mostly in the low 20s, yet still dropping frames. This happens on instant replay and graphic overlays. I have about a month till my next webcast, so I'll be able to test the new overlays specifically to see if those drop more frames than my old ones.

  • Jerel Peterson If it worked for a short time and then stopped working there has to be a variable. Reseting Preferences if they became corrupt would be one thing you could do. Otherwise it could be the codec used for the overlays. The hardware hasn't changed obviously. Monitoring would impact GPU use. The new Wirecast 11 might handle things better.
