Thanks. Sounds like we might have failed to open the hardware encoder and fell back to software encoding for some reason. I’m going to try to get some time on an iMac tomorrow and see if I can recreate the problem.

Ok I took a sample. https://gist.github.com/kballard/636fa3f6c09d6fc6e2a2a1efa3354cc9 https://gist.github.com/kballard/636fa3f6c09d6fc6e2a2a1efa33... I also checked the Console. Here's what I found: default 19:55:42.767418 -0800 RetroClip GVA info: preferred scaler idx 1 default 19:55:42.769327 -0800 RetroClip AVD encoder error: kAVDPictureEncode CreateContext, unsupported resolution 5120 x 2880 default 19:55:42.808188 -0800 RetroClip Using metal device <BronzeMtlDevice: 0x7f80bf037200> name = AMD Radeon R9 M395X default 19:55:52.609993 -0800 RetroClip LSExceptions shared instance invalidated for timeout.

  My hero! Sounds like I should do some scaling for these 5k iMacs. I got away with up to 3840x2400 resolution just fine in my testing on various macbook pros, but I don't have any iMacs. I'm gonna go try one at the Apple Store tomorrow (not buy obviously, I'm way too cheap for that, but just use it for a minute). EDIT: Yeah, I'm pretty sure 3840x2400 is the max supported by any recent Intel CPUs, and older ones are less. The iMac Pro might be a special case because I hear it uses its GPU for H.264 encoding. Anyway, querying what the max is for a given machine and then scaling to fit it was an easy fix. Hopefully I can get it deployed to the app store soon.

    Glad to hear it! Not sure I need a 5120x2880 video anyway. I’d be perfectly happy with half that resolution. I assume higher resolutions have a larger memory footprint. Is the RAM usage still reasonable at 3840x2400?

    Finally just relaunched it again after the updates. it's now taking 10% CPU while watching a Twitch stream and 1–3% CPU when not. That's much better than 300% CPU :D
