Editing 4K 100mbps Clips on a Macbook In: Cameras Posted 17 hours ago 42 minutes ago, SRV1981 said: Thanks @tupp I am using a combo of iPhone and Sona A7III video. If the files coming off of those devices are compressed, your machine (and NLE) has to continually uncompress those files on the fly, while applying effects and filters. It's a huge demand on the computer's resources. 42 minutes ago, SRV1981 said: Additionally, I am making videos from Keynote for animations etc and layering all of these clips sometimes picture in picture etc. "Keynote?" That sounds like a cute Apple name for a presentation app. Make those clips uncompressed at a low bitrate. 42 minutes ago, SRV1981 said: I am just not sure if it will take a long time to create proxies... How long and how many are your video clips? Try creating proxies with a couple of files, and see how long it takes. If you have a lot of clips to convert to proxies, you could also build a cheap Linux box and batch render your proxies (with ffmpeg, handbrake, mencoder, etc.) to a fast SSD drive. Then, edit off of that SSD. That workflow might payoff if you are doing three videos a week. 42 minutes ago, SRV1981 said: ... I am making anywhere from 1-3 videos a week, which is to support my job as a teacher. Evidently, teaching has changed dramatically since I attended school. You are making more videos per week than a lot of pros make in a month. If this is for teaching, why do you need 4K? Try reducing the resolution to HD and reduce the bitrate wherever possible. What happened to chalkboards? 42 minutes ago, SRV1981 said: Apple has offered $480 for my 2015 MBP and I was looking at a 13" 2020 MBP 2 ghz, 32gb ram, 512 SSD for $2100 or $1600 after giftcard. US $2100 for a small 2Ghz laptop with a 512 SSD?! Before dropping that kind of money for a laptop of questionable power/quality, I would look into streamlining your workflow, as suggested above. Again, with any MacBook (or any Mac) that has a T2 chip, make sure that secure boot is disabled.
