Question

Proxies stutter

I shot a film on BMPCC6K using .braw. Proxies were made from within Premiere using "Create Proxy" funstion [sent out to Media Encoder) and project window shows clips as "attached".

           - Proxies are: Apple ProRes 422 Proxy, 1280 × 720,  data rate around 14.61 Mbit/s. format.  

 

All original files are stored alongside their proxies on a standard 7200 rpm usb-c G-Drive. I didn't want to edit using orignal files and wanted to make another version more portable so I stripped out all the proxy folders and copied them on to a Samsung SSD T5. Working from that drive I've encountered this issue: 

          - "Toggle Proxies" is on, all FX are muted

          - when trying to playback from the timeline (in the program monitor) the footage always stuuters and skips terribly.

           - when playing back a clip used in the timeline (reveal source in project) viewing it in the source window it plays back fine. Even when I make a new sequence from the clip I still get bad stuttering in the Program window and lagging machine performance in general.

 

My specs:

Premiere Pro 22.0.0

macOS Big Sur 11.5.2

Model Name: Mac mini

  Chip: Apple M1

  Total Number of Cores: 8 (4 performance and 4 efficiency)

  Memory: 16 GB

FWIW I shoot 6K BRAW and edit it on a 2019 MBP (Intel) and I get decent playback at 1/2 rez without proxies. However, I use an SSD Raid that gets close to 500 MB/s. That's actually pretty slow but BRAW isn't super intensive. Check the speeds you're getting on your drives; I think the G-Drive is going to be very slow (7200 rpm spinning platters do not benefit from USBC speeds) and your T5 only gets up to 540 MB/s. If the T5 is not getting that speed then check that you're using the right cable. 

 

As a troubleshooting step, try putting the proxies on the Mini's hard drive directly and see if they play properly from it.

I agree with @John V Knowles, please avoid using a single spinning disk for all editing. Invest in SSDs or a RAID cabinet.

    Thanks guys! I'll try moving it to internal disk. BTW the spinning disk is only for archiving the footage, I'm not trying to work from it. Oddly, the problem seemed to be fixed by turning off one of my monitors...
