Essential Sound: Clip Content Analysis getting stuck on long clips

[Rumpelstiltskinn]

Not sure if anyone else has run across this, but sometimes, when I use the Essential Sound and apply a dialogue preset (in most of my cases: Dialgoue > Balanced High/Low Tone Voice), the Dynamics tab gets stuck and displays the message "Clip Content Analysis in Progress." 

I've restarted, cleaned cache, and rendered out the seq (in case it was just a preview thing)...none of that helps...BUT what does help, is if you go into the Effect Controls for the Audio, and then de-select and re-select the Fx icon for Dynamics Processing, the magical Priemere Pro gears get unstuck and the audio is processed. 

I've cut the track into smaller segments, and then perhaps one gets unstuck and processes the audio but the others don't ever complete processing, even if they're much shorter than before (I assume because the original file is still one large/long audio file).

How long are the clips you're analyzing, and what audio codec are they using (e.g., AAC, PCM, MP3)?

~ 10 to 15 min .mp4 video clips with 48000 Hz - Compressed - Stereo audio.

You might try the following steps to help Premiere Pro complete the Essential Sound analysis on longer clips:

1. Split longer clips into shorter segments – For example, divide a 10–15 minute clip into 5-minute sections. This can reduce the processing load and help the analysis complete successfully.
2. Use an uncompressed audio format – Converting your audio to an uncompressed format like WAV (Waveform Audio File Format) can improve compatibility and processing speed during content analysis.
