Also , what in that vague article proves your point ? <| sep |> I don ' t want to be discouraging , but you can hardly do much work on modern cars yourself without a being a trained mechanic and b owning the proper tools . Cars have gotten way more complicated over the last two decades . While it is probably not totally unheard of to do some minor work , even on modern cars , your limitations have vastly increased . <| sep |> 10 mins to 4 hours depending on their supplies and how long it takes them to die . <| sep |> I ' ll let others answer on PC specs as I don ' t know for certain . As for helping you now , honestly , if bitrate fixes the problem then that ' s not much of a compromise . Honestly it might even just be playback rather than the recording . I ' ve seen very high bitrate video stutter like that . With that said , the average person will not see a huge difference between 20 and 40 Mbps . It ' s there but it isn ' t major so dropping that might be a good start at least to see if the quality is still fine for you . Like I said , YouTube will reencode it anyway . Yes , it will encode better if it has more information to start but you ' re recording far more than you probably need . As for issues related to chrome and stuff , and it could help here , have you checked activity monitor to see if you have any page outs or swap used in your memory ? You may just need to add more RAM which should be cheap and easy I don ' t own a mini so I can ' t say for sure . Chances are that it ' s a power problem but I would say you should at least test things out first before jumping straight to needing a new computer . Chances are a few adjustments can get you up and running .
