Now that I have taken a lot of video and pictures with my
inspire2 , x4s . I need to do some editing this winter. So want buy a better computer then what I have . I was thinking about 1 with ,i7 Processor , 16 gb ram, 2tb hard drive . Any thoughts out there . ????
There is a good deal of video's on you tube that describe the 4K editing machine... decide if you want a MAC or PC. In either case, decide if you want to edit with Adobe Premier, Dinvinci Resolve (Free and very good), or Final Cut (Mac Only, but doesn't use lots of compute to edit 4k).
The going wisdom in the PC world is to go with a thread ripper (AMD) these days, I bucked the trend and went with an Intel I9. If your going with an Intel i9, its considerably more money than the AMD, but fi you do it, the 7900x (10 cores @ 3.3) works perfect and if you want to spend a bit more cash get a 7940x (14 codes @ 3.1) = lots of tests show that going more than 14 cores slows down Premier / Media Encoder. Not sure what it does for Divinci (which has a free version for personal use which is great).
At the end of the day, decide how much your willing to spend, that will dictate what you will get.
I just jumped off the MAC platform as honestly if your using anything other than Final Cut, its WAY over priced and really slow for either Premier of Divinci. Seems to be better value in a PC if using the Premier or Dinvici. Also, not sure if AMD has it, but the Intel Chips have a technology that encodes H264 for youtube really fast (near real time). I don't know if AMD has this or what it might be called. This is a big help when exporting to YouTube formats.
Also a OpenCL video card seems to be the best choice for best performance for most effects, but check with the video editing software capability list to ensure you get the right video card. I don't buy AMD video cards, but if your going to get an nVidia the 1080ti is the best performance/cost. It works very well with Premier. I went with a TiTAN Xp which is a little faster, but way more money (like twice). I would not do it again.
If getting an i9, you must get all in one water cooler block for the CPU, they are not expensive so don't worry about that.
With all that Said the i7 has a very good value and all the video card stuff still applies.
you got lots of choices, start with money, then pick PC vs MAC, then Pick Video Editor, then pick CPU (Cores # matter as per above), then pick a video card for the system is the basic logic.
I hope that gets you started... I spent months looking at youtube videos to get a sense of what was going on with new video editing PC's - but at the end of the day, its all about how much you can or want to spend, the rest falls into place as per the order in which to make decisions.
as for Video outputs, pretty much all the new video cards hand display port and HDMI, but make sure you get HDMI 2.0 and a TV that supports HDMI 2.0 as that's the only way to get 60 FPS output from the video card for your external monitor, if you get stuck at 30 FPS it looks terrible. Also keep in mind that if your single monitor setup is big enough (I edit with 40 inch displays) you really only need one display for editing.
BTW; I built mine around the ability to play back 4096x2180 @ 60FPS - I record in that now. Youtube also started converting to VP9 (Which is used in place of h264, they don't look like they will support h265/HVEC - so I picked a CPU that could handle the largely software decode of VP9 which playing back 4k youtube content. The i9 CPU I got plays back 4k @ 60 FPS with easy now from both the X4S and YouTube, my Mac could not play it back smooth at all.
Good luck with your decisions....
