the files written by dji phantom are hefty compressed. premiere 2017 has really problems with scrubbing, but the video starts without a delay.
mediacomposer crashed on import 1st time and playback/scrubbing is more or less
unusable (cpu usage is less than half of lwks while playing*).
*which normaly would be a good sign

v12.6 beats all ,-)
( but playin also not optimal)

hard to see a delay.

On my PC the strong fluctuations of CPU utilization are a problem (4k media, example: play clip):

At 100% I get only one still image (LW seem to buffer?).
Then the clip will play for a few seconds.
During this time, however, CPU usage drops to only about 10%, instead of using the time to buffer.

Edit: The GPU still seems to have reserves

My RAM utilization is also high.
I am unclear whether the data transfer is the problem.?


In the case of 1080p media, the CPU utilization is also very fluctuating, but then does not cause any problems:

I made some tests with 4K long GOP AVCHD to compare media players performance with Lightworks, initial buffering delay, playback and seek and yes, Lightworks does a very good job even compared with those machines which are supposed to play only in one direction, forward.

EDIT - but, there's always room when you try to reach the sky.
Keep on pushing!

machines are fast enough ,-)

but depends on how many cores are used + native gpu support
