Keyframes in audio effects ignored (BUG)
When exporting to h.264 from Premiere Pro CC 2018, the Media Encoder ignores the first set of keyframes in audio effects. This results in a weird jumps in the audio effects at the beginning of the video. To replicate:
1) Apply the Mastering audio effect to a clip
2) Create some keyframes with initial values for a few parameters
3) Create a second set of keyframes later in the clip that modify those same parameters
4) Create a third set of keyframes modifying those parameters
5) Export the video to h.264 mp4 using Media Encoder
Video should contain audio that tweens smoothly between the keyframes.
Audio track starts with the values specified in the third set of keyframes, then jumps abruptly to the values in the second set of keyframes when playback reaches that point in the video. Keyframes after this seem to work normally.
Reset the status of the job in the queue and re-render the video. Media Encoder will only honor the keyframes in the audio track the second time you render that job.
This workaround is annoying because you must render the job twice to get one proper video.
