I don't know. In the case of the external disk above it seems a hardware limitation. Either the disk or the USB3 interface of the disk or the computer. [/quote] ok.. see if the quote thing worked lol. So just to be clear, I have been building computers, networks, etc for many years now.. only saying that to ensure that for the most part, I understand the various speeds that USB, SATA, etc should be able to do. Not that anyone was totally questioning that of me, but wanted to throw out there that I do have the knowledge of the basic hardware stuff. It is in particular with ffmpeg that I am blundering. With that in mind, lets assume I had nothing but SSD drives. My laptop has 2 NVMe 960 EVO drives, and one SATA3 SSD. For clarity, it is a SAGER desktop replacement laptop.. not very portable. Also has a 2TB Firecuda SSHD and 64GB RAM with 6700K cpu. What sort of speeds should I see when concatting two DNxHR SQ 4K videos together? That would help me understand better what to expect. I would assume from some other posts I found around the interwebs, that I should see 150fps to 300fps with this process, not what i see now at a paltry 9fps. If this is a CPU bound task.. the CPU indicates it is using 1% total.. but the disk usage shows at about 20%. So I would assume that I am still not being hampered by disk i/o given that it is not maxed out. I will be building my threadripper system in a couple weeks.. I hope that ffmpeg will benefit from the 16 cores and be much faster... assuming I can get past whatever the issue is with why it is so slow now. _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
