Time flies so fast. I checked and found that I actually bought it in 2012. At that time it was the fastest in the store. Anyway, it has NVIDIA GeForce GT 630M and Intel Core i7-3610QM CPU @ 2.30GHz. The adapter provides 120W in the output. I think this is more than enough, because Toshiba eco utility shows that it consumes 40-60W while exporting. I don’t use hardware encoder, I tried it but it didn’t make any difference.
I played with power options and saw the driver called Toshiba Power saver regulated power consumption quite well. As soon as the temperature of the CPU was about 90% of max the driver just halved the speed until the CPU cools down. I think something disrupts this idyll.
While my account was blocked for several days because of this my post (they said I typed too fast), I created about 50 videos (thanks to Shotcut!), and had a chance to watch what is going on in the system using PC Health monitor and Task Manager, playing with power options, and here is what I saw.
When I start exporting video Shotcut, quite often it disappears from Task Manager’s radars. Manager shows CPU that usage goes up but there is no app that uses it. Can it confuse the power saver driver? As I saw with a very bad timing a defragmenter and an antivirus can jump in, and – kaboom, BSoD comes out. All exporting with the maximum performance options run on the edge with a cooling fan speed of 95% and CPU usage of 90%. A little push can topple down PC.
Another bad thing I saw, which is a memory leaks. I exported one video and when Shotcut finished Task Manager marked it as “not responding”. Shotcut held about 2.6Gig of memory. But in fact it was working and I just started editing another project and when exported it Shotcut had 4.5 Gig, and with all other apps PC worked at 99% memory usage. Can it cause problems?
Also when I played video inside Shotcut, every play allocated additional 1Gig of memory and didn’t release it, and after closing the project 2.5Gig was on the loose.
So, I think Shotcut has problems working with Windows, but this happens not all the time, but quite often. I hope my observations would help.
