Zoom local recording conversion speeds


What determines the speed of conversion of local recordings. I regularly record and convert meetings on 5-7 computers at a time. I have various computers with various specs, but it seems like higher spec doesnt always convert faster. Which computer specs and settings determine the speed of the local recording conversion? For example I have a 5 year old dual core Lenovo thinkpad with 16 gb ram and 7th generation i5 which processes faster then an 11th gen i7 with 32 gb ram?


Trying to figure this out as I buy machines specifically for this purpose

Hey @VadimK, when converting the local recording are the two meetings that are being converted the exact same in terms of length of the meeting, shared content during the meeting, quality (HD), etc.?


I'm unaware of the specs required of the converting process for local recordings however, as long as your system meets our requirements to run Zoom I don't think the speed of the converting process should differ much. Did you notice a huge difference in the time of the converting process of your local recording?


Assuming its based of the number of processes your computer is running whether it be applications open in the background or not which would determine the conversion process time (I think). You can monitor the consumption of Zoom for your CPU in Task Manager. Also, the possibility of the length of your meeting -- which usually is double the time to processing.


I can do some more digging to find you a more accurate answer!

I record the same length of content at the same time on many computers and there are drastic differences between them but the two lenovo T14s with i7/32 gb ram are by far the slowest even though they have some of the best specs, and I don't run anything else on them except for the zoom.
For example, my 3 or 4 years old Lenovo thinkpad t590 with a slower older processor and half the ram can convert a 1 hour zoom in about 20 minutes and the t14s would take 35 for the same thing.
And then I have a 2014 macbook pro with very low specs that does it even faster.
My main PC with i9/64gb ram etc... Can convert a 1 hour recording in just a few minutes.
All zoom accounts have the exact same settings and are doing the exact same things. I would love to find out how to speed up the slower machines, as it greatly affects my workflow.


Check the Task Manager for which resource is in use the most while you transcode.  I suspect the CPU but maybe it's GPU. And I also suspect that there are one or two single thread processss doing the processing, so it doesn't matter how many cores the CPU has, what matters is how fast is one core. That you can verify from Passmark's website by looking single thread score.
