rendering slowing internet connection

[Chris Robinson]

Hey . thanks for your response!

The network only disconnects when rendering a project file that is located on the NAS. And randomly.

It is only the computer that is doing the rendering. I can go to another one of my edit stations and the internet works. It only happens when rendering and on that workstation that is currently editing that project file. Other computers are able to access the NAS while the one station is disconnected from the network.

As far as throughput, I am not 100% sure. We have aggregated bandwidth of atleast 10GB/s. The workstations have network cables working in tandem (bonded) to provide 2GB/s speed on each workstation.

Also note that normal editing does not effect performance. Everything is fast and runs smoothly until you render. If you render with the scratch disks on the local disk then it works but defeats our purpose.

Again thanks for your help. Any advice or tips or anything is GREATLY appreciated.

Unless you’ve checked the box to “Use Previews” as an encoding source, the location of the scratch disk shouldn’t really affect this process outside of using conformed audio perhaps, but that would be in the location targeted for cache…

Are your encoded output files also targeted back at the NAS?

One thing to keep in mind…editing doesn’t have the hard, constant, simultaneous read/write duplexing going on that encoding does…it’s more read-heavy. If all the files need to be read from the NAS, and also the finished file is being written to that same device, the network connection may easily be max out in both directions…the reads from the disk actually slowing down the writes to the same disk and vice versa.

On a bigger disk unit, I don’t know if it would be a problem, but you might be uber-loading your NAS depending on what sort of data you’re using.

Thanks for your quick response again.

When exporting video to the same NAS device, we noticed that it does disconnect from the network more often than not. When exported to the Deskop of the local hard disk, all seems to goes well.

So it would appear that your theory would prove correct, however I am not sure how that explains the disconnects when using the “Render Work Area” function while working in the project … (Not exporting just rendering work area)

If your scratch disk locations are on the NAS…that’s where you’re rendering to…

A preview render is mechanically the same process if your scratch disk destination device is the same as your encode/export target device would be.

Thanks all for your responses. I just wasn’t aware that ones internet connection performance was so dependent on the CPU. Glad to know it isn’t an issue with the software or my hardware but it just is what it is. Thanks everybody and have a great day!

I can’t confirm that we are uber loading it.I will check when I can get more administrative access to that device.

This is the same device used to create and produce the movie Avatar so I don’t know how we can be over utilizing it on one render. Again, I will check. Thanks for your time.

I opened up my Network speed statistics when rendering. When it works fine it reaches aruond 20MB/s of transfer strictly from premiere. When it freezes and loses internet connection the SEND and RECEIVE packet speed drops to about 1-4 kb/s .

It is acting like it doesn’t even want to attempt to SEND packets.

Yeah…I am…NOT…a networking expert in any way, so the last thing I want to imply is that some component in your system is somehow inappropriate, under-spec, malfunctioning…or even unpleasant to look at.

🙂 …because I don’t know.

All I’m offering is the process that Premiere Pro is going through when these functions are happening to hopefully help you troubleshoot.

Keep in mind that targeting the preview video and audio render files to a local disk may not be the worst way to at least deal with the issue in the short-term to keep things working…

Good luck with it.
