- jenadine 4y agoBut if you want to share it or store it, it is not practical to keep the raw data. You will have to re-encode.
- happymellon 4y agoLike the codec used to get the stream from Netflix to you, to be decompressed for the capture card (so lossless capture of a lossy source) and then back through x264/265 so lossy compression on a lossy compression. Just because there is a capture card in the middle doesn't stop it going through multiple lossy steps.
