Insert keyframes for each change in data frame?

[vanakema]

I'm going to start with defining two similar terms to reduce confusion

• Frame: A single frame of video in the video stream
• Data frame: A single unique frame of data representing a portion of the encoded file

This issue is written under the assumption that there are multiple frames in the video stream representing the same data frame.

In video encoding there's the concept of keyframes which is kind of where it "resets" the frame. Sometimes you'll notice a video stream gets super messed up, with weird blocky artifacts, and then it cleans up, almost like it's on some interval. That interval is when the stream reaches a keyframe.

I'm not sure if YouTube will actually respect the source video's keyframes, but if it does, we could enhance the quality of each unique data frame by dropping a keyframe each time a unique data frame is shown in the video stream.

Video size would definitely go up, but compression artifacts for each data frame would go down significantly
