Automatic audio transition between clips and export

Hi!

I have a quite simple situation: I have a sequence with multiple video clips. I add a music to all the clips and I want then export each signel clip as an individual video. The thing is that for the music I want to have a fade out to silence at the end of every clip and a fade in of the music at the beginning of the next video so that each exported clip start with silence, then the music fade in and before the end the music fade out and we finish in silence. Hi have many many clips so I would like to automatize this process... 

 

Also I would like if possible to export each single clip automatically without the need of setting in out point for each of them.

 

Thanks a lot!

Luca

Attached is a block script for Automation Blocks for Premiere Pro which does the following:

 

1. create a project bin "temp sequences"

2. loop over all clips of track V1 of the active sequence and create a new sequence in the temp sequences folder for each of them. The new sequences contain the orginal active sequence as a nested sequence, but trimmed to the range covered by only that particular clip. The script then applies a fade in and out of the audio by appending keyframes to the channel volume property of the clip.

So as an end result, you have a ton of sequences in the "temp sequences" folder, each containing one of your clips with faded audio. So all you need to do then is to queue all those sequences for rendering.

 

To run the script, just
1.download the xml,

2. load it into Automation Blocks

3. in the inputs panel of Automation Blocks choose the fade duration
4. run the script. 

Here is also a detailed explanation of the block code, in case you want to customize it further:

You can do this, but Premiere doesn’t have a one-click “auto fade per clip” button. The easiest workflow is:

  1. Put your music on its own track.

  2. Cut the music at every clip boundary (use Sequence > Apply Edit to All Tracks so the cuts match your video cuts).

  3. Select all the music pieces and apply Audio Transitions > Constant Power so every piece automatically fades in/out.

  4. For exporting: use File > Export > Media > Source Range: Individual Clips (or Project Manager >  Transcode — “Exclude Unused Clips”) to batch-export each clip without manually setting in/out points.

This way every exported clip starts and ends in silence, and you only set it up once.

    Hi Mathias,

    Thank you soo much it looks great. Maybe I have to do another post but I realize that maybe I need something slightly different. Ideally I would like to have one folder with the clips, one folder with the musics. Somehow each clip is exported with a music and the (AI) Audio remix tool is applied to match the end of the clip's lenght (so no more fade out but Audio remix tool applied).  The musics are used so that one music is used one time than is not used before all the other musics have been used at least one time (so that we use as much music diversity as possible). Does it make sense? Thanks a lot!

    You cannot run the Remix tool via scripting, I think. So that part will stay a manual step.
    But to automate everything else, I just added this tool to the Community Library of Automation Blocks for Pr for you:

    Sequence/Create/Create A new Sequence For Each Selected Project Item And Add Random Audio.xml

    It loops over all selected items and creates a new sequence for each of them. Into the sequence it inserts the clip itself as well as a random clip from the bin "audio" of your project. It makes sure to first use all audilo clips once before using one a second time.

    Here is the full code with explanation:


    Dear Mathias, your work is just amazing. I am discovering Automation blocks only now and it looks incredible!!!

    I am now tring with a lot of pain to make one script out of the 2: actually I would like to have the second  scritp that creates automatically the sequences with random audio but also that (from the first script you did) we can choose a fade out option (actually the audio trim tool does not behaves so ideally with short clips so the fade out solution looks the best!).

     

    I dont know if you can help me into this.

     

    Thanks a lot in any case!

    I wonder if Automation Blocks could do that? @Mathias Moehl
