请教用来压X264的VFR是V1和V2哪个好?

v1 timecodes works by setting an assumed framerate (the "Assume xx.xxx" line at the top) and then defining ranges of frames as having other framerates. The format is
startframe,endframe,frames per second
v1 timecodes are nice, because they're a lot more readable than v2 timecodes, and because they're human-editable.

v2 timecodes on the other hand work by defining a timestamp (in milliseconds) for each frame in the video. The timestamp determines the frame start time, and hence the first line after the v2 format definition must always be 0 or weird things can happen. The example above shows a framerate of 25 (because 1000/25 = 40 milliseconds per frame). v2 timecodes are kind of a pain, because they require that the output has the exact same amount of frames as the input did. This can occasionally be very annoying. However, there are tools to convert v2 timecodes to v1 ones. See the tools section at the bottom.
