A video stream production system with the help of MacBook, BMPCC and Konka PS300

For those who are engaged in video shooting and editing, MacBook, BMPCC and Z CAM movie camera cannot be bypassed. With excellent color management and screen display color accuracy, coupled with the excellent editing software Final Cut Pro, MacBook has become one of the excellent choices for many video workers. The professional movie machine can ensure that the picture can be recorded as perfectly as possible and provide room for post-modification.

The relatively simple shooting and editing process is to copy the video file to the MacBook through the data cable connection after shooting through the BMPCC, but after using it for a period of time, I found that this process has many drawbacks.

First of all, on the shooting equipment, BMPCC and Z CAM both use CFAST 2.0 memory cards as internal storage, and the writing speed can reach more than 400MB/s, which can guarantee the shooting of 4K RAW video, but the price of CFAST 2.0 memory cards is not high. Up. The price of a SanDisk 256GB CFAST 2.0 card is 450, and the price of a 512GB card is 900 usd, which is more than ten times the current SSD price.

The storage of MacBook is also a pain point. Everyone knows that the storage capacity of MacBook is one level worse, and the price of the whole machine will be 1000 to 1500 usd, which is far more than the price of SSD with the same capacity. Space capacity requirements are also very high.

So I was considering connecting the external SSD to BMPCC and Z CAM for recording, and then connecting the external SSD to the MacBook, and editing directly on Final Cut Pro, reducing the storage cost without adding a step A large number of video files are copied to the MacBook and then edited, which can be said to save money and save trouble.

Since 4K RAW video material needs to be recorded and edited and previewed in real time, the performance requirements of the hard disk are relatively high, at least it must be able to achieve a reading and writing speed of more than 300MB/s, so that a series of mobile mechanical hard disks Excluded. But at the same time, we need to consider the problem of hard disk heating and speed reduction. Although NVMe’s mobile solid state has a high speed, but the heat generation is not low under long-term use, so we finally decided to choose SATA mobile solid state hard drive, which can meet 300MB/s performance , The heat is not too high.

The mobile solid-state hard drive used now is Konka’s PS300 mobile solid-state drive, which uses the USB 3.1 connection protocol (now renamed as USB 3.2 Gen2x1, the wise USB is named after). The hard disk itself uses the Type-C interface, and can be directly connected to MacBook, BMPCC and Z CAM through the included Type-C to USB-A cable and USB-A to Type-C OTG head.

In terms of speed, it takes about 1 minute to transfer a 21GB video file recorded in the Konka PS300 to a computer, and the speed can reach more than 400MB/s. Therefore, it is completely possible to store video files directly in Konka PS300 for editing directly, and 4K HD videos can be previewed in real time.

As for the stability of use, after nearly a month of actual use and editing, Konka PS300 can maintain normal operation, recording video, and direct editing have maintained good stability.

If you still agree with this process, you can also try it. However, it should be noted that many cameras provide Type-C interfaces, but they do not actually support external hard drives. For example, the Sony A7α3 and Canon 5D4 that my friends are using do not support it.
