In live view, the bitrates are about 30% higher than when I watch the playback. Take for example that if I have around 100KB/s peak for the live view, if I watch the same sequence in playback, I will have around 70KB/s peak. It happened after a firmware update in January. I will try to find it. I have 8 V2 and 3 Pans V1 and they all have the same problem. My V3s don’t have it.
For the quality, since the bitrates are lower in playback, the viewing has more artifacts than live. If you zoom in a little, the difference is even more obvious. I have seen you example. They are the same but you are not in continuous recording. I don’t know if it is make a difference…
