The problem of rendering mainly depends on whether the software is suitable for the decoder in which high-definition format. I use Sony's VG 10E, and the video format is a common MTS, but ordinary video editing software can't recognize that AVCHD decoder must be installed. Many editing softwares are self-contained, such as audio/video 12. 13 and EDIUS5.5, which can be directly imported without decoding and directly lettered after rendering.
According to my personal experience, the tape drive has to collect, render, output, package and engrave, and the multi-image quality in the middle link is very damaged, while the sd card is directly imported and exported for rendering and engraving, which greatly reduces the image quality damage, which is obvious compared with the tape drive of the same level.
In addition, ordinary tape acquisition generally outputs AVI format, which is more common for computer editing. MTS has high requirements for computer configuration. Don't think that it requires more graphics cards. Instead, you need a higher CPU. Now, apart from Mercury engine of PR CS5 supporting GPU transcoding, it mainly relies on CPU for transcoding, so quad-core INTEL processor is necessary. AMD mainly has advantages in games. If editing videos, Intel is the first choice. This is my humble opinion. I can keep communicating with you. Thank you.
PM: Dear you, the SXS card of EX 1R is really expensive, but the SD card stands on Taobao are everywhere. A colleague of mine uses EXIR, the Cato, and I bought him a high-speed SD of 100 yuan, which is very powerful. No problem.
