Hello, I was looking for some knowledge from people who have experience with mixvibes video plug in. Before I get too detailed, here are the specs of the laptop i am using with mixvibes.
Cross 3.4.0 64bit running on
Acer Aspire E5-573g
Win10 home 64bit
Intel Core i5-5200u @ 2.2ghx (4 core)
*8gb ram
SSD
gfx-Display: intel HD 5500
gfx-Render: geforce 940m (total mem: 6gb, VRAM 2gb, Shared 4gb)
ok, here we go...
I vj/DJ, and use mixvibes on a dedicated laptop for video mixing only, i run other software for music mixing on a separate laptop. so keep in mind all of the issues i am describing will come with no idea what is happening with the sound, just video output. I usually have deck a and b normal and deck c and d as 4 slot sample decks. if those decks are empty, i usually don't notice playback issues, there generally are none if samples decks are empty. often times, though, when I have 4 samples loaded on each deck (small file sizes on these sample decks too, like 50 to 100mb MAX mp4 files for example, either triggered or turned off) i'll notice that my video output framerate drops noticeably. applying fx or transitioning will make the framerate drop even more. most of the time if i unload one deck of samples, i see some improvement, or if i turn off some of the more taxing video fx, output performance improves. When this happens, I am running HDMI to a 2 way splitter. The output performance framerate drops display on the screens as well and the preview windows in mixvibes, but the performance of the PC itself seems to remain alright (I can alt tab or browse files without frame hiccups).
So on windows 10, if i right click the shortcut for Cross i can select which gfx card to launch th eprogram with (launch with integrated or high performance gfx card) I generally launch it with the high performance (geforce940m)., i am going to try using the integrated one at my next chance i get early in the night just to test. i generally run nothing else while vjing, i have set CPU minimum state to 100% all the time, i made sure the usb ports don't go into low power mode, the laptop is on a high performance power plan, it does not go to sleep or shut off hard disks (there is a HDD in it in addition the the SSD, all programs, operating system and video are running off the SSD) i am wondering where the issue might be. i put the laptop into airplane mode while running Cross.
my laptop exceeds the system requirements. Does launching with the geforce card actually make a difference? is/can Cross utilize the performance a geforce 940m can bring? Is the 940m, while good at alot of the games i throw at it, not good for whatever method Cross uses for video decoding/output? Does Cross even utilize gfx cards for video tasks, or does it rely solely on the CPU? is it making use of all four cores? can i force it to do so if it can but is not? is there a preferred video format that Cross prefers? preferred file resolution? are my laptop specs insufficient for the amount of videos i run simultaneously?
does anyone have any ideas on how i can improve video performance? Thanks in advance for your time.
