MacOS vs Windows - Graphics Cards and Render Times
O.k. before I get into this I'm NOT trying to stir the hornet's nest in terms of how fast or slow HitFilm is compared to other programs, Mac vs Windows, or complain (far from it) about speed - instead I'm trying to figure out how HitFilm uses resources when rendering and why machines that are much more powerful than my own seem to be having speed issues.
So here we go (strap in, this is going to be long).
My computer is a mid 2012 MacBook Pro.
The basics are:
i5 dual core 3210M
16gb of ram (1600)
Samsung Evo 850 SSD
Integrated Intel 4000 graphics
So it's an old computer with integrated graphics, and in my mind HitFilm should barely be useable, but it's not. HitFilm actually runs rather well, much better than expected in fact.
What I don't understand is some users with seemingly MUCH more powerful computers with dedicated GPUs, 4 cores, tons of ram, etc. sometimes have render and speed issues.
I tried Shotcut and OpenShot before finding Hitfilm and they were totally unusable - editing in their timelines would stutter, and stutter badly. Thinking I was going to have to buy a new computer (or find one to use) I tried HitFilm Express 2017 and to my amazement it's incredible smooth, even with 4 to 6 video and audio clips being used/rendered at one time.
The footage I'm using is 1080p at 23.976 fps in AVCHD/h.264 format.
Renders take around 1.8 X footage length - so a 2:35 second trailer takes around 4:30 to 5 minutes to render (without hardcore effects like denoise - that does take forever).
So a 5 to 6 year old laptop with only two cores and an integrated graphics card is totally fluid when editing and the render time is what one would expect, yet I'm reading about these much more powerful machines having problems, and I'm wondering why.
Btw, when rendering cpu use on my machine usually goes up to about 80% and RAM use is about 14GB.
Could this be a MacOS vs Windows issue? or a Windows version issue? An SSD vs HDD issue? A ram issue? An expectations issue?
I'm delighted that Hitfilm works so well when editing and slow(ish) render times are acceptable for such an old machine.
I don't get it.
Anyone have any thoughts?
