Hello, I have a 2h30' footage in mp4 format, cutting and arranging pieces of it takes a toll on the computer, due to continuous decoding of the source file to viewable footage on the timeline. How can I make the whole process lighter? Maybe converting the mp4 source file to raw? I did it and the file was 264 GB, so it does not solve the problem.
What type of disk are your footage and/or transcodes on?
If that disk is a spinning hard disk, there's your bottleneck. No spinning disk has ever had a simultaneous I/O throughput of more than about 75 MB/s. (Do not confuse this with the maximum sequential read or write speed, which is throughput in only one direction.)
Even a SATA SSD is being pushed to its simultaneous throughput limit with your particular footage.
