At my church I'm currently replacing a Hikvision DS-7608NI-E2/8P NVR with a Hikvision DS-7608NI-I2/8P NVR. Firmware Version V4.61.025 build 220905. On Smart playback the speed up and speed down are greyed out, forward and reverse work normally. The event markers are in Red as they should be. Speed up/down works in Normal mode. I’m beginning to think that’s the way it is supposed to work. I can’t find an answer. Can you confirm if this is normal?
