    "Analyze speech to create text metadata" But how?

    Guy Burns Community Member

      On page 269 of the PDF it states:

       

      Analyze speech to create text metadata

      1. Select a file or clip.

      2. At the bottom of the Metadata panel, click Analyze Speech, or Analyze (Adobe Premiere Pro).

      3…

       

      Whoa, we can stop right there. I imported a test clip from my GH2, draggged it into the Sequence Panel (what is the proper name for that window?), clicked on it and it turned a dark blue, went to Window > Metadata and Analyze was greyed out. The clip plays okay, but won't be analyzed.

       

      How do I get Analyze Speech to work?

          With the clip selected in the Project Panel,

          hit the 'Analyze' button (circled).

          You will then get this pop-up:

          Set your preferences, then hit OK.

          Media Encoder will launch, and automatically begin the analysis.

          Once it is finished, close Encoder, return to Premiere, and the

          analyzed text will appear in the Metadata Panel (with that clip selected).

           

          note:

          Speech Analysis isn't perfect... but it can give you a good start.

            My Analyze button is permanently greyed. I think I know why. Whenever I upgrade to a new OSX (as I did before installing the Adobe Master Suite), I clone the raw OSX to a disk image (A), then add all the software and clone that to another disk image (B), then get rid of everything I think I don't need (every language other than English, most of the fonts and voices, and gigabytes of other stuff), and create my final disk image (C). I reckon I threw out when generating C something required for speech analysis. I'll reload B and see what happens.

              I just cloned my OSX (B) to an external drive, fired up Premiere, and the Analyze button was still greyed. The problem is not with my OSX after all, it's with Premiere's inability to deal with certain types of sound files when analyzing. I've tried three sorts of video files, and on my setup:

               

              1. Premiere can't analyze the audio component of .MTS video files from a Lumix GH2 (sound codec AAC).
              2. It can't analyze the audio part of .mp4 video files from a mobile phone (sound codec: AAC)
              3. It can analyse the audio content of .AVI files from a camcorder (sound codec: PCM)

               

              So the situation appears to be that Premiere can play certain audio but can't analyze.

                I don't have any AAC audio media to test.

                Can you upload a clip somewhere?

                 

                note:

                This might be a limitation of Speech Analysis.

                  I have uploaded two files with AAC audio to this folder. One is from my GH2 (.MTS) and other is from a friend's mobile phone (.mp4). The latter is an interesting file which may become the subject of yet another post, because the audio is out of sync with the video.

                    00001.MTS - (AC-3 codec)

                    I could not get Speech Analysis to recognize this raw file, either.

                    00001.MTS.png

                    Speech Analysis worked:

                    After flipping it in Media Encoder to Ut .avi (PCM),

                    After flipping it in Media Encoder to .AAC audio only/44.1kHz,

                    After flipping it in Media Encoder to MPEG2-DVD (PCM),

                    After flipping it in Media Encoder to H.264 (AAC),

                     

                     

                    So... .AAC codec does not appear to be any problem.

                    I would suspect the original file's AC-3 codec (or the

                    method of  multiplexing) to be the culprit.

                    This file does not play in A/V sync in Premiere for me either.

                    This sync problem is likely the result of the file's variable frame rate.

                    Premiere doesn't much care for VFR media files.
