How did Justin do this in Reaper? (video inside)
https://www.youtube.com/watch?v=q2Cw7V-iyt8
I know he said this was done in Reaper but I have no idea how. I have an idea for a dumb little comedy sketch where I'm interviewing myself and this sort of thing would be essential for me to be able to pull it off. Thanks! |

It's not edited. How do you think he develops so much stuff by himself?

Just create a logo in Photoshop with an alpha channel, which sets the visible area, save it as png with alpha channel, import it to Reaper and use the "image overlay" to only see the chosen pixels. Same is possible with video, but you need to create the alpha channel for it. An alpha channel is nothing more than a black and white instance for what pixels will be shown (color white) and what areas are transparent (color black) and of course all the greys in between. Justin did record five videos and created alpha channels so they only show a specific range. Maybe its already possible by using fading or vignette like effects in video processor. But i have no idea. Hope that helps to understand. Its not to complicated to make an interview with yourself. |

He filmed 4 videos (one video per reaper track), then used the crop preset in "video processor" to expose just the sections where he was standing in each video, which is a plugin for video items/tracks. Crop is part of a preset, not it's name, the color changes came from the stage lighting preset in that same video processor JS plugin. Just search for video processor in jsfx.

The process is literally as I described. 4 videos on 4 tracks with the person in different positions in each video, use crop to expose the underlying tracks. A side-note that video only displays the top-most track, but when you use crop it exposes the video in the track below and so on. So... if there are 4 people across the screen so to speak, one is cropped to the leftmost 25%, the second the next 25%, and so on.

I haven't tried installing Vegas in WINE, and if I can do most of the things I used it for (mostly personal entertainment), I could just start using REAPER in place of it. |

Reaper is perfectly capable for basic video stuff and will still use it but once you get into color grading and some of the more advanced stuff, something else is better which is expected. Still though an awful lot of basic video editing is perfectly doable in reaper.

If I can do simpler video stuff and still have some cool functionality all within REAPER though, I might start using it for some video tasks. |

It's doable and you can automate the video params (pan/zoom/crop/etc.) as well. Perfectly capable for basic editing and is what I used up until early sept.

Slightly off-topic: I came up with the idea to interview myself after a similar video I posted to Facebook had such a great reaction. There was a possum my house a few weeks ago, so once I finally trapped him (at like 5 in the morning after he somehow made it into my bedroom) I promptly started to film a talk show in a Rachel Maddow/Charlie Rose kind of style and it was largely improvised. One of my strangest and fondest memories to date.

Wow that's a real possum, where I come from that looks like lunch.

It's not just cropping. You can see the background ghosting through him (the "bass Justin" and "electric guitar Justin"), and sometimes he "leans in front of himself" etc.
If I had to guess: he took a frame of video of the background (probably from the video in which he was drumming) and used that as a basis for creating "subtraction" for the other videos. Exactly how I'm not sure since I haven't played with this kind of thing yet. |

I also have to correct me because png images don't save an alpha channel rather than just saving the transparency of the image. So it seems Reaper doesn't have alpha channel processing. At least i didn't find it.
Sorry, I was just assuming from my memories. |

Way off topic, but my favorite part of the video is the Jesusonic box on the floor in the background!

------------ To everyone.... the term subtract with pixels just means turn pixels that are the same between layers black, or possibly transparent in this case, so it could be used to accomplish the same as with feathered cropping but at the end of the day, it's the same desired result. The last time I did this, I used a crop simply because it was so easy.

I don't use Reaper video editor, and I haven't had time to check my theory but ...
There's a "blend mode" used in video/image compositing (the interweaving of pixel layers) called "Subtract". Justin's video is called "Subtraction" so I'm guessing that he used a Subtract mode to blend the layers - possibly in order to get the cymbals to appear in front of the Acoustic Guitar Player. (also, using Subtract maybe then led to the unintended effect of the background layer bleeding through the Bass and Lead Gtr players). He also must have used a Crop or Mask on the left side of the screen, as you can see the Ac Guitar Player disappear while walking off. _ |

FWIW, the video processor preset subtract works this way IIRC so anything moving gets rendered, otherwise black, it's pretty cool looking actually, no need to listen, just look - it's from last year when I was testing reaper vid and a looper at the same time. If two videos are overlayed, the black is probably just the underlying video content per Justin's demo - haven't tested though. I am pontificating some here but I think it's close.

That one was made by writing some processors that subtracted a reference image, then added to the common background. I'll see if I can dig up the project for it, I think I posted that at some point...

Here it is:
https://1014.org/_/subtraction.zip 224MB -- I re-encoded the video files down to a really low bitrate (1.5mbps vs the original 25mbps) to keep it manageable in size. It looks a bit crap but you get the idea. That link will only be valid for a few weeks so if you want it, get it now! The baseline tracks have a "sample and hold" preset on it that avoids having to decode the video file (making it perform better) -- if you removed this, it'd still work, but probably look a bit different as the noise profile of the background would change... The way all of these FX interact is really fragile, I think after doing this I improved the way FX presets can get frames from other tracks/etc. but I forget. |

Thanks for sharing Justin, it's great to see the project broken down. I'd definitely check out the band that had this vibe going on.

Yes, thanks very much for sharing. More (at least Windows) users should know how straightforward even sophisticated video edits are in Reaper, esp. when it comes to audio dubs. The time I've wasted with the likes of things with 'Pro' and 'Magic' in the name. And don't start me on Windows Movie Breaker.

I spent like an hour or so looking at this last night. Played around with the different video processor presets that were in the project. Came up with something in the ballpark but it kinda ended up looking like the Take On Me video.
Little did I know that this kind of thing takes literally 10 seconds in Davinci resolve and looks flawless. It was worth a shot in Reaper, though. I love seeing all the crazy stuff we can do with it, even if some of it is impractical. |

Davinci Resolve kicks ass, bar none. I still use Reaper for certain video projects and love it, but some more complex concepts are better in Resolve et al.

I'm guessing it should be fine, unless the content creator gave specific instructions not to share something, or released it with a particular license. And I don't think either of those apply in this case. |

It's really better to ask. No need for specific instructions, that's automatically implied by being the creator. Either way, it's a better call and good form or respectful to Justin to ask and be sure.

But now it doesn't make sense, because the link is inactive. Just wrote about it.

Okay, got it! Yep, if he made it available for a short time, there must be a reason. I think that's because the code doesn't look great and Justin as a programmer is shy to show bad code.
