rendering about 15 seconds of 8k video has taken 30 minutes. Now, it reached 100% but has not finished yet, and the CPU jumped up to 100%. Is this normal? Is it still "finishing" or is it stalled out KIA? ELAPSED TIME is still counting up, Vegas still seems alive.....
anyone else with 8K render experiences here? Should I kill it with fire and retreat back to 4k?
I will add it's been in this 100% wait state now about 15 mintues.
k, it finished, 3 seconds took about an hour total. maybe others have this happen

yyeeeeessss.... but the point here is that it "FINISHED" at 100% and THEN just sat there. Usually, when I render, it hits 100% finished, waits a second or two and then is DONE. Ready to open and check.
This 8K did not operate like my 4K. It could maybe sit at 99% for a while instead of claiming to be "done" when it is clearly still doing a lot left over.
A watched pot never boils. Do you understand that it takes Windows four times longer to write the temp file to output than does 4k?
I have rendered 20 seconds of an 8k 8192 x 4096 HEVC 24p source file to 24p Grass Valley HQX 8192 x 4096. This took about 3 minutes on my dual core 2,6 GHz notebook with Intel Graphics HD 520 on board (which I think is considered to be low powered).
And vice versa: I took a 20 second 24p HQX file which is 8192 x 4320 and rendered to HEVC 24p 8192 x 4320 which took about 14 minutes (and it lasted about 2 minutes to be finished after it reached 100 %).
My guess is you're doing a frame size and/or a frame rate conversion which takes longer then.
Which kind of 8k source video do you use?
Which are your project settings?
Which are your render settings?
yes, was upscaling a 4k to 8K, so I guess that was it. File ended up only 65MB, with plenty of drive space, but was way longer than 4k renders - like 8 to 10x longer. just found it weird. was a fun test and proved nothing, except I wont bother outputting 8k. :D Since there is only 7 people in America that can view it natively anyway :D
the pause after 100% seemed wrong though
At least probably there is zero reason for upscaling to 8k, but some real use cases for cropping from 8k sources.
20s 8K 30P rendered in 2:18s All 16 cores ran full tilt 100%. No GPU support. Vegas rocks ALL 16 cores baby. Were told Vegas use only 6-8 cores bla bla bla. Wrong. Task manager shown all 16 cores rocking full tilt. :)

I built my system when 4K was new, so, I'm sure its way out of date nowdays :D :D It def maxed out my CPU though
By using 6K capture on my G9 (H265) I can create 6K video on my i7700/4.2-4.4 32 gig ram Rx480 8 Gig (I use proxies. Rendering is much slower than 4K, but I've been cropping the 6K (wildlife) and rendering it to 4K. If you don't have a large core processor I highly recommend (if your final output is to be 4K or 1080P) doing nothing more to the 6K or 8K original files than cropping and perhaps some color work. A 4k computer is just not going to give you a good enough work flow if you want fast render times on the 6/8K file IMHO.

Now you need a new system that is 8K ready :) Go team Red my friend.
sony vegas pro 13 was/is already using all 40 cores at 98% each here when rendering ( GPU=OFF , dynamic RAM to only 25 GB ( out of 128 GB ) ) . Later versions of Magix should do the same or better , I would expect ;-) ( my system specs are in my profile )
