just my 2cents experience with vegas 11, 12 and 13.
my pc specs:
motherboard: Asus Z97 Deluxe
CPU: i7-4770K overclocked to 4.4 GThz at constant clock meaning no intel stepping and boost and water cooled with NZXT kraken 62
GPU: Asus GTX970 strix (yes the 3.5GB one)kept out of the box
2x8 GB 2133Ghz DDR3
Win 10 Pro 64 Bit
OS drive : Samsung 960 M.2 NVME 500GB (vegas is on it)
Tempory files folder is also on C drive above
video files are rendered to D drive : 3TB HDD (i have 2 in my pc and not sure who is the D drive but one is hitachi and the other is seagate barracuda)
also have stuff that isnt related to vegas : the 2th HDD , 1SSD 840 pro 128GB 1SSD 840 pro 256GB
i use CAM to monitor the pc and this mostly because i can see the water temp.
idle core temps are around 45 to 55C at 4398,97Mhz and 1.27V and goes between 4.5 to 30% atm on cores (not the cpu count) kraken is in performance modekraken fan speed at 75% cpu fan about 600 to 1000RPM and pump 3480 to 3600RPM water temp 37C ,RAM load is at 23% atm at 3.7GB GPU is at 38C 17% load core 135Mhz mem 324Mhz mem load 0.28GB fan 0 RPM
now this sayed i had alot of problems with GPU rendering enabled and only could render when this option was shut off so it stays off in this pc config.
now i gona do some testing and put the number in here .
beside the normal stuff i have zone-alarm running in the back opened Cam in advanced mode also taskmanager , this browser and realtempGT for this purpose.
the room temp is 25C so its hot here today lol.
first i will test an short video (about 4 min) main video mixing already pre-rendered i have 5 video lines and 3 audio lines . video's are in overlay methode and audio in paste mode . the file is rendered as mainconcept AVC/AAC mp4 internet 1080p format
the video will not be pre viewed in full second screen. just the in GUI preview.
last idle control:
taskmanager: cpu 1-4% mem 22% up to 3.6GB
realtempGT: max 54C min 38C on view about 43C single core
CAM set to hour : cpu min 37C max 62C over all cores GOU 37C core 135Mhz , mem 324Mhz mem load 0.26GB fan 0RPM
rendering:
Taskmanager shows 100% load at 4.38Ghz
realtempGT shows 96 to 100% load min 38C max 78C single core
Cam shows CPU 4398Mhz temp min 37 max 78C 94 to 99% fan at 1060RPM pump at 3600RPM fan 76% GPU up to 4% load 38C mem load 0.27GB core and mem clocks stays the same RAM 25% 4.2GB load
video result can be seen at
test 2 the final video is rendered in 2 parts while the whole video is rendered as fully the added on screen text is added on 2nd rendering . This video is much more complex i have 97 lines 1 audio ( pre-rendered as its an mixwith enhanced audio))and 96 video lines.many manual effects are added beside auto zoom effect. the video is about 40 min and rendered in about 2Hrs.
rendering:
Taskmanager cpu 100% load 4.38to 4.4Ghz Ram 28% 4.4GB of 15.9GB drives goes up to 3% as far i sawed and that only for C drive.
RealtempGT cpu 99.9% load at 4.4Ghz min temp 38C max temp 80C
CAM
cpu 4.398,97Mhz fan 1056RPM temp up to 85C because of the long run temp gets higher and water temp goes up to 43C
RAM 4.5GB 28%
GPU up to 5% load 0.32GB mem load temps are 37 min and 42 max

So here you go its not Vegas badly supporting multithread but its your hardware and settings that gives you problems. in my experience and from i saw alot of youtubers ,the rendertime is always about twice of video lenght exept when complexity is added.
its a knowed fact that dealing with complex rendering you have todo pre-rendering so it helps render times and that means while you're editing ,have to plan what part should better be pre-rendered .in test 2 for example at the beginning you have the zoom effect that are many small parts after each other so its better to pre-render this as full part as each part ads complexity .also an good example if you want to render 100 very small video views in one screen . thats 100 parts and if that is just a fill in for another video its better to render it apart.
i dont use adobe premier and yes adobe has much more addon tools but the rendering is the same from i saw and hear from others.
i advice you to watch this video :
that shows adobe on the best workstation hardware from intel and AMD but be aware that intel is downclocked to the AMD lvl to compair it fairly.
in hardware i give this advice:
CPU : use 4/8 intel up to how much you can afford. the intel 6/12 6850K beats in small margin the AMD 1800X 8C16T we dont know yet how the new 6core 12 thread perform (7800X) so cant advice this one and its possible that the 1800X could be better choise then. if you use intel 4/8 K or 6/8 K/X always overclock the cpu to increase render speed .found out what the max stable overclock is of your cpu and then lower about 200Ghz (also lower the voltage) for long and stable cpu performance)
For example my 4770k max overclock is 4.7Ghz but it was to much voltage so i kept in mind that the max clock is 4.6Ghz so i lowered down to 4.4Ghz and to stablize the cores i turned of intel steppings and boost so it stays around 4.4 from start up to shutting it off.
Ram : use atleast 16 GB total of ram and atleast 2 sticks . use high clock with lowest CL (my DDR3 2133 is CL 5 and is faster than any DDR4 2133 Mhz) for DDR3 use 2133Mhz as any higher doesn't give much perfromance boost with a to much ad of cost . for DDR4 3200Mhz is the one you want to go with .with the lowest CL possible. if you buy the one i say then DONT overclock it with intel cpu's and you can tighten them up but is not needed.
GPU: while my own GTX970 should work well with GPU rendering it always crash the software while rendering.if you have a GPU that works then use the GPU accelerated option as it will help render times...well it should ...not for me ....if you use an second screen and watch rendering preview then DONT use the GPU rendering and you will need an beefy card if you want todo it in 1440p or 4K , meaning you gona need at this time the GTX 1080 or more likely the GTX1080Ti
Drives:always use an fast SSD as C drive .Go for the NVME ones if you can afford it and also use it with the best connection meaning possible . dedicated PCIE 3.0 or M.2 (PCIE) is much better than Sata
For Temporary files i didnt saw any improvement to use it on seperated drives . not for HDD or SSD (ive tested with the 840 pro 128 and 256 ones ) thats why i kpt it on the fastest SSD aka C drive
for final file its ok to use an HDD (its better anyway to hold all your library's on a HDD due the limitations of SSD overwritings) i also use HDD for everything i can . i mean downloading from the net into the download file is on a HDD drive but also the OS my music,video ,documents etc . you can google it how todo so.
Motherboards: you will be surprised that i say dont cut on your motherboard but the fact is ,there is an reason why the high end stuff is more stable and have more stable ability's. PCIE lane cuts from chipset or CPU is an good example or PCIE ability's (the X4 ,X8 ,X16 and also chared PCIE). i am an fanboy of ASUS for sure while the enhanced features of 15 years ago has shifted to other features all asus MB i had and have (P5E , Z87,Z97 atm) are (still) working without any problems. i use mostly the deluxe or if not needed the full function then i use the A version (example Z97-A) as its an cut down deluxe (cutdowns are extra features for specific needs like wireless ,dual Lan,etc) im not gona advice you what to look for when you want to buy an Motherboard as this is about vegas and not specific hardware topic.the asus bios /UEFI have always been the best but dont use the auto overclock software (only to test out what cpu can do as mainline then delete the software . always do the OC yourself)
PSU : another thing that people cuts alot on but shouldend. i advice you to buy a 1000W power supply in any cases as you will overclock CPU use highend GPU use fast SSD and use many drives together . on my PC (specs above) i got already 2 PSU dieing on me
both where Corsair AX top of the line PSU one is the 860i and the other 860 now i use the 1000W RM (i think ) and no problems sofar while the other 2 gave problems from the start.you will read alot that you dont need an 1000w PSU and you will be fine with 700 or 800 or even lower but every specific use of an pc needs other specs.
cooling:use AIO watercooling . it will simplify your life. give secure higher overclocks. while i use NZXT kraken now (i did and still use some other AIO on this and other PC's) specific because i can see in CAM software the temp of the water itself .for noise reduction use the biggest rad and the largest fans possible (counts for all fans in the case ) 140MM fans are better then 120MM fans to reduce noise so 140,280,420 rads are better than 120 ,240 , 360mm rads but also 420 is better than 280 and 280 is better as 140 (actualy deny on the 140 and go for atleast 2 fan rad)
dont go for the fancy ,pancy features as RGB or good looks but go for good headsinks on MB ,etc ,the needed features, positif airflow,enough of the good connections (USB3 types are a mess to keep up lol), good specs and do research ,alot of research.dont depend on one person advice (mine included )and try so see a line in the results (if majority overclock to 4.4 and some can go for 4.6 then aim for 4.6 but be satisfy with 4.4 if 4.6 is out of reach and dont aim for the 4.8 that a few are telling but try it yourself if you can reach it)
headsinks on SSD is/will be the future as SSD loose performance on heating up and o boy those SSD gets hot .(that was announced 3 years ago that this will be a problem).
Do you need all this expensif stuff? not at all. everybody start on the ladder that the wallet can handle but if you want to go semi-pro render its an good advice to follow .(pro renders are for me those that use pro industrial hardware).
it seems that these days everybody makes video's and render as a youtuber or stream on what ever(even 8 year old ones) and all have theyre own opinion based on who knows what. i shared my own experience and its up to you , the reader ,what to think about this.
sorry for text wall but i hope it helps all readers.
Ruangi out....time to make some video's lol.
