Render Razor Edit Areas Together to Audio

[ferropop]

Hi, I've really tried but this is outside my skills. Hope this might be easy for someone willing to help!

SR : Make Razor Edit Areas, script renders all areas together to a new item.

Pseudocode:

1. Make a table of all tracks that currently contain Razor Edits, "retracks"
2. Make a temporary dummy track at the root level of routing, "dummysend"
3. Send each track in "retracks" to "dummysend", post-fader
4. Render post-fader the "dummysend" track, with boundaries from Left Edge of First RE to Right Edge of Last RE
5. Place the "dummysend" Render track near your last-selected track or cursor
6. Delete the "dummysend" track, which deletes all the temporary sends

This sounds VERY hard (to me at least). Reason:



How should this render be handled?

EDIT: But wait, we have Razor edit areas as source in the Render window. So maybe it could be used.

I imagined starting with the simple case of a single Razor Area, with a clear start and end, and then going from there in complexity once that's shown to be possible.

The idea here would be: draw a box - render the box to Audio. Mucking with Time Selection for this precise style of edit still feels so strange to me.

Its definitely a cool idea

Like the number of times I accidentally attempt to use Razor Edits to "Render post-fader" type behiaviour, really speaks volumes. Can a scripter comment on if something like this is doable? It seems that if I can literally perform those operations by hand, that in most cases it should be reasonably straight forward?

Ferro have you tried the Stem Manager script? Will that get you the right end result?

I'll look again, I think that script does far more than what I'm hoping for, and maybe not as directly. Like I'm hoping to simply get the equivalent of "Render Tracks in Time Selection to new track (post fader)" with Razor Edits.

RE are just such a more direct way to interact with media, it's such a better suited natural extension for those actions than Time Selection x Tracks.

So you want to basically render, let's say, a track, but only the razored areas, ignoring the gaps? So you skip them?
Or rather a file where you only hear audio where razor areas are, the gaps are silence?

I don't really get it from your pseudocode, after having read it.

[Triode]

In the native render to file dialog there's an option to render razor edit areas. I've never used it but in combination with hitting solo on the track combo you want that might do it? (and possibly bypass master track FX?)

There is this very useful script:
Render time selection to new track

Is the same you describe, only with selected tracks + time selection instead of razor area

Hi Mespotine, I'm starting with the simple case here of a single area selection :



Even if just this could be scripted it would be a huge life improvement.

Again, what I want is "the contents of the area selection" be rendered "together", and to achieve this :

1. I make a new Track, and Send all the tracks involved in the Razor Edit to this new Track "DUMMYSEND".
2. I then Render this track DUMMYSEND, at the time selection the same size as the width of the Razor Edit. DUMMYSEND is receiving the desired signal from the involved tracks in the RE, so rendering this gets us what we want.
3. Then I clean up... delete the receive and it deletes all the sends automatically -- perfect.

[ferropop]

And yes definitely more complex to have non-contiguous area selections... I'm just hoping the simplest case I show above is possible, as it's already a tremendous improvement.

I understood that they shall be rendered together. My question was: shall the finished file have them rendered one after another, without gaps?
Or with silence at the points where there were no razor areas?
I try to determine a scrioting path, but I need to know in detail what the final file should be.

I've been using a script for a long time that fits this description. This could be a Razor, a selected area, or simply selected items:

Thanks for sending this !

I'm trying to find out how it works, because if I phase invert against the original selection they don't cancel perfectly. Is this rendering through all the busses right up through the master?

When I do it by hand (like I show above) it's phase accurate -- just curious how this works before I start doing things that might get me in trouble with phase!

I'll be honest - I don't know how it works My friend made this script a long time ago, I just modified the script by adding Razor Edit and removing some bugs.

I know for sure that it takes into account processing on the tracks, but not the master. But I don't know how it reacts to the busses.

In the case of a single Razor Edit selection, there's no gaps so the finished file would be exactly from beginning of RE to end of RE.

With multiple RE, it would be cleaner if each RE "block" was a separate item... but I can see where this maybe gets complicated.

Even more complicated if you have non-rectangular selections... when I proposed this I was just thinking of the simplest situation and trying to script it myself so I didn't let myself think this far. One approach would be to separately render each Rectangular section per-track, put those items temporarily in a folder, and render the folder... this way you're getting the combination of them playing together from the separate renders.
