Rendering Multiple tracks of different lengths with no padding for silence

[vonboo]

Heya, I'm finding this to be a tough one. I'm wondering if Reaper can do this. I have 90 voice files that I need rendered separately. They are for a project that does not require them to be lined up, but their lengths must be preserved. Imagine it's for a computer game.
I can do each file separately but that will take a long time. regions won't work as each track is a different length.
How can I render all the files in a queue, preserving the length of each track without having to do each track separately?

Am I look at SWS? Automation? Any help would be appreciated.

Possibly. You're certainly looking at a custom action.

Something like this?



^ This being:

X-Raym_Render selected tracks individually through master.lua

If you can specify exactly what you want the custom action to do, somebody will show you how to do it.

Would either one of the last two options there do or did I misunderstand?

LOL

I guess that would do what OP wants.... I have a habit of missing the obvious.

Sounds like a job for the region render mattix...
Create a region for each piece of audio you want rendered, and pick the track(s) to render for each region.
If you have large numbers of items to do, there might be an action to autoconvert all the selected items to separate regions and name each by itemname or trackname.

Created a script for this exact task. Instead of Selected tracks Razor edit areas should be used as a source. You'll get all the tracks from the beginning of the project to the last item.

reaper.PreventUIRefresh(1)
reaper.Undo_BeginBlock2(0) 

for i=0, reaper.CountTracks(0)-1 do
  tr = reaper.GetTrack(0, i)
  count_items = reaper.CountTrackMediaItems(tr)
  if count_items > 0 then
    item = reaper.GetTrackMediaItem( tr, count_items-1 )
    item_end = reaper.GetMediaItemInfo_Value( item, 'D_POSITION' ) + reaper.GetMediaItemInfo_Value( item, 'D_LENGTH' )
    reaper.GetSetMediaTrackInfo_String(tr, 'P_RAZOREDITS', '0.0 '..tostring(item_end)..' ""', 1 )
  end
end

reaper.Undo_EndBlock2(0, 'vitalker razor edits: enclose everything between start of project and last item on all tracks', 1)
reaper.PreventUIRefresh(-1)

Here is another version, which selects everything between left edge of first item and right edge of last item:

reaper.PreventUIRefresh(1)
reaper.Undo_BeginBlock2(0)
reaper.SelectAllMediaItems( 0, 1 )
reaper.Main_OnCommandEx(42630, 0, 0)

for i=0, reaper.CountTracks(0)-1 do
  tr = reaper.GetTrack(0, i)
  if reaper.CountTrackMediaItems(tr) > 0 then
    retval, razors = reaper.GetSetMediaTrackInfo_String(tr, 'P_RAZOREDITS', '', 0 )
    first = razors:match('[%d.]+ ')
    last = razors:match('[%d.]+ ""$')
    reaper.GetSetMediaTrackInfo_String(tr, 'P_RAZOREDITS', first..last, 1 )
  end
end

reaper.Undo_EndBlock2(0, 'vitalker razor edits: enclose everything between first and last item on all tracks', 1+4)
reaper.PreventUIRefresh(-1)
