Premiere too slow
Posted by Duong Cam on September 3, 2020 at 12:40 pmHi, I’m using Premiere 14.3.1,
It too laggy when preview (10bit – Quicktime from Davinci).
My PC: Ryzen 9 3900X – 32Gb Ram 3200 – Nvidia 1080 – HDD Toshiba X300 Performance – 7200, 128mb cache
When it render, My HDD is 100% (CPU and GPU too small).
Please help meChris Galgon replied 4 years, 3 months ago 6 Members · 6 Replies -

September 4, 2020 at 4:07 am-How to edit video on a slow computer in Premiere. It makes super small file sizes that can play back on slow cpu and slow hard drives. Think 400x smaller(400MB clip becomes 1MB clip!)
Easy to follow youtube video to make proxies in premiere since you can customize the video size to abnormally low quality like 320×240 in resolution(needs to be even multiple fraction size) and 1 mbps bitrate.
The real trick here is in export video, advanced video-keyframes. set it to “1”. This will make h.264 turn into an all-INTRA codec(i.e. no delta frames so your cpu doesn’t have to work at all)
If you’re working in a small window, you don’t need 4k proxies.(You can toggle off for grading.)
Additionally, other good proxies are cineform(smoother than prores if using offline grading) if you go that route and dnx proxies)
You can also set playback quality to 1/2 or 1/4.making custom ingest proxy presets-

September 4, 2020 at 10:08 amOne key element missing from our description is your media storage. Drives – type, number, connections?
System:
Dell Precision T7600 (x2)
Win 7 64-bit
32GB RAM
Adobe CC 2017.1 (as of 8/2017)
256GB SSD system drive
4 internal media drives RAID 5
Typically cutting short form from UHD MP4, HD MP4, and HD P2 MXF. -

IMHO no user would venture that size.
I haven’t seen that resolution in any NLE since 1995.
And that was usually the export size for CBT (computer-based training) CDs/DVDs.
This day of age, check your drive option and see where it stands compared to base codecs e.g. DNxHD/HR, CinemaDNG, ProRes, etc…
Most pros do not edit in h264 due to the compression codec messing with your mind ☺
Good luck. -

September 4, 2020 at 4:53 pmHe just needs to get it working first, then he can play around with making larger/higher quality proxy files… and H.264 is just a container. you can create any compression/quality that you want with including leaving out delta frames for low cpu usage.
This is all just a misconception of the technology. plus if he doesn’t have a lot of space, the proxies could take up most of his drive. Not everyone does this professionally so they may not have the ability to playback larger bitrate codecs because of the hard drive transfer speed limitations.
I would personally prefer Cineform Wavelet compression as it uses less cpu overhead compared to older DCT codecs(H.264 is DCT like both Prores and DnxHD) and has less artifacts. H.264 just got a bad rep because everyone added millions of delta frames and forgot they were optional. In many cases, it can look better than other codecs at similar sizes/bitrates, even at 10 bit. Main 10 is also supported.

September 9, 2020 at 2:04 pmAre you trying to edit this off a single HDD? Be better off with a RAID that can handle faster data rates. Check out this calculator, don’t forget audio will add more data rate and there will be overhead, but you can get a rough idea of the data rate you need and compare to your HDD. https://www.digitalrebellion.com/webapps/videocalc
Also use something like BlackMagics Disk Speed Test app – you can Google it. Use that to test your actual data rate on your drive.

February 5, 2022 at 4:04 pmI know this is an old post but I just discovered turning off hardware decoding (preferences>media) solves major speed problems on both my Ryzen and M1 Mac systems when using Premiere.
