try audio at 44.1

well,
“Set to Frame Size” and “Scale to Frame Size” are different
“Set to Frame Size” retains the original high-resolution for panning around.
“Scale to Frame Size” will rasterize the image smaller. any upconverting later in export will be image degradation.

change the sequence setting to match 1080 unless you agree to the two above ways

there’s loads of things you can check to make sure your getting good playback performance:

Since a lot of people have been having problems with smooth playback,
here’s my total “make everything playback smoother” solutions chart.

1. un-ticked “Enable accelerated Intel h.264 decoding” in preferences/media tab and closed extra premiere panels-hidden?
2. add premiere in NVidia Control Panel as an application for discrete gpu
3. power option-maximum performance

4. Make Sure The Composite Preview During Trim is Turned Off and also make sure your Reference Monitor is Also Closed it Will Help Solve the Choppy Playback
5. Set Preferences : > Audio hardware > Default Input: to None

12. disable “High Quality Playback” setting in the monitor wrench menu improves gpu
13. disable mercury transmit
15. freezing up on mac permission issue

19. Changed Audio Hardware from MME to ASIO.(lower level audio driver for lower latency)
20. Limited Premiere’s RAM allocation to 32Gb if you have 64GB
21. In task manager, set affinity to utilize only 16 cores for PP (unfortunately, this setting does not hold on re-launch)
23. in bios, disable Intel Speedstep.
24. disable C1E – in the bios, power settings,change to performance.

25.
– go to CTRL+F12 and find these settings: top left change to debug database view
– DisableSpeculativePrefetching – set this from false to true
– ImporterMXF.ReadBlockSizeinKB: default is 1024. Experiment with this.. I’m trying 2048 with good results
– CodeProfiler – set to true
– GPU.EnableGOPFormats: set from false to true
– Player.MainMaxOutstandingAheadofPlayback=3 ://10 default
– Player.MainMaxQueuedFrames=10 :// 300 default

The above two can make a difference. Higher values if you’re working 60P rates.

26. set audio to 44.1 in hardware and premiere
audio pref – disable play audio while scrubbing
disable maintain pitch
audio hardware latency 200ms

disable sequence composite linear color
sequence audio settings 32000hz
sequence settings preview file 1920×1080 1/2 size video frame size 3840×2160 then 1/2 size playback

27. in monitor, pull markers together so there’s less tick marks per inch, the playback marker will go offscreen while playing back.

i can’t recommend any system directly unless you know which version of adobe premiere you want to use.
example:
cs6 4gb ram intel core 2 duo, 7200 rpm hd
cc 2017 8 GB ram multicore proc.

for smooth editing, using a proxy with cineform, negates worrying about a slow cpu, but still needs
a decent hd disk speed. ssd’s are getting very cheap now. find one that matches your footage’s r/w speed.

720p is only a resolution. h.264 720p takes 4x faster processor than cineform 720p for realtime editing.
and multiple video tracks will suddenly bog down a 7200 rpm disk. you can get a 850 pro for $100.

don’t forget frame rate, frame size get gpu accelerated as well, so software mode may not be your best bet.

since you posted your budget is $300, try to find a i-7 quad with a cheap cuda gpu and a modest SSD. should be okay for 720p.
you might have better luck buying a laptop with a gutted drive, then install ssd yourself.

read this very carefully. then report back

also, the version of premiere matters a lot for ram allocation, cpu speed?
did you use to render during workflow? premiere now has proxies.

the old cs6 could work files offline manually, or you could simply copy to master folder
what version of premiere do you have?

[Chris Wright]

check your camera settings. was it shot in vlog? is this ungraded?

[Chris Wright]

Uncheck Import Premiere natively in the Pref of AME.

[Chris Wright]

deleting media cache is first thing I’d try. also, any special luts have to also be in media encoder technical folder as well with same file structure.

[Chris Wright]

does it match if you click in photoshop convert profile to rec. 709 16-235? proof colors needs to be on to see what it will look like in premiere as rec. 709.

[Chris Wright]

does it appear if you render out of adobe media encoder dnxhd -click->config video levels, not full range. that should render out 16-235 instead of 0-255.
also, AE has utility color profile converter input 16-235 rec. 709 output rec. 709.
