I throw the file on the timeline in Premiere 2019 and see output delays in the Program Monitor, a “cotton” reaction to the “j, k, l” keys. It's unpleasant to work.
Configuration: Win 10, Ryzen 2400G, 16 GB, 1060 GTX, SSD per system.
Tell me, please, should such files be rewound forward / backward without brakes on such a PC, at different playback speeds and do other joys of convenient navigation through the video sequence? Or is it too weak a configuration for such files? CUDA acceleration is enabled in settings.

Answer 1

This is how it should be, because you have an inter-frame codec (one key frame, N after it are derivatives), which means that the PC constantly makes calculations in order to play the video. Plus, when you rewind, the PC first looks for an I-frame, and then it calculates the one you rewound.
For editing, they came up with editing codecs, in which each frame is a separate, intra-frame. For example DNxHR\DNxHD, ProRes and others - convert video to them, and then work with the converted video. They take up a lot of space, but they rewind beautifully.
