mulit-cam editing

Is it possible to create a multi-cam video from two video files that VIRB Edit doesn't recognize as being started at the same time?

I used two VIRB Elites to record a bike race that were started at the same time using my Garmin 810. I imported them to version 5.1 but had to downgrade to get the overlays to work. When I downgraded, I still have the video files, but they no longer are associated to their gpx files, and VIRB no longer recognizes them as being started at the same time so I can't do picture-in-picture video editing.

It seems as tho the start time shouldn't really matter and that mulit-cam editing should be an option whether the videos are recorded in sync or not. Why can't any two videos be used to create a mulit-cam video?

Or is it possible somehow to restore the data associated with these files in the VIRB Edit database so VIRB will recognize them as being started at the same time?

    Hello jeremystitt,

    I havent found a possibility. Garmin tries a lot to prevent using footage from different devices.
    It´s somehow understandable. They put a lot afford in it and dont´t want you to use it for free (in the meaning of not owning a gamin camera).

    But that also means, that you cannot use the feature, even if you own two cams, when something is not 100% right.
    It happens if the time on both cameras is not exactly the same. So you have to activate GPS to make that happen. It will set your time.
    Even that will not ensure, that it will work :(

    I´ve mentioned that earlier here.

    Got 3 days footage, where the time was not exactly the same and cannot use it.
    The other day, I´ve got 3 turns on a racetrack. Just the one in the middle worked (GPS activated on X & XE. Waited until both got GPS signal. Paired by Remote. Turned off. Turned on & started recording at the primary virb).
    Until now, there is no possibility to overlay the recordings. Even if both got G-Metrix and should have the same timestamp...

    I have 2 VIRB Elites - one facing forward and one facing the rear. They get turned on nearly simultaneously and I feature should be able to share the same G-metrix input file for keeping the data in proper sync. The problem would then become how to intercut clips between the two inputs.

    I haven't yet really tried to intercut clips between the two inputs, YET.

    You will have two G-Metrix Files and select the source per clip. Combining is not possible. But in my eyes not needed. It should be equal :)
    When Virb Edit finds two G-Metrix files with overlapping timestamps, the PictureInPicture function promts automatically.
    Editing is like cutting from a single recording.

    My feature wish would be, to synch the timestamp on every remote connection. Front Virb starts the second virb and submits the time. Then it is possible to disable GPS on the rear virb. (Which actually is just needed to have the right time and to consume battery)

    But it still works without using the remote functionality, as you can see here :cool:

    Is it possible to restore the G-Metrix associations with the video files so the Picture-in-Picture function will prompt again? I believe I have all the necessary data, but VIRB Edit doesn't recognize everything together like it does when I import straight off the camera.

    What picture-in-picture function?

    Is it possible to restore the G-Metrix associations with the video files so the Picture-in-Picture function will prompt again?
    What picture-in-picture function? I didn't know Virb Edit had that capability. How does one access it?

    Just started to play with multi camera operation. Both my VIRB Elites get turned on within seconds of each other and are located within inches of each other - one faces forward and one to the rear.

    In trying to use the multi cam feature of VIRB Edit 4.2.3 it outputs 2 streams. A stream is nominally the forward camera and B stream is nominally the rear camera. I would have expected both A and B streams to cover the entirety of the video being edited - but that is not what I am seeing. Steam A seems contiguous beginning to end, however stream B doesn't begin until about 12 minutes into the 30 or so minute video. WTF?

    I haven't had the courage to update to VIRB 5.1 - it doesn't Export on my desktop machine without crashing and I am not anxious to perform the update on my laptop only to have to go back to 4.2.3.

    Following is a screen shot of VIRB Edit 5.1.1 screen attempting to use multi-camera editing of one of my racing sessions.

    Camera A & Camera B are both VIRB Elite's that are mounted to the roll bar fairing, A is configured for right side up video and faces forward, B is configured for up side down video and faces rearward. The camera are turned on within seconds of each other when I reach over my head to turn them on. Car movement starts approximately 5 minutes after the cameras are turned on.

    Now having problems getting the screen shot to load to this post

    I can confirm that. It is not every time, but mostly there is a huge gap between the recordings.
    One day in Rijeka, Croatia worked amazing. Cam A started, and Cam B begun ~2 seconds later. Virb Edit matched it automatically and the 2 sec. gap was equal.
    The other day in Mettet, Belgium, I got 3 recordings, and only one of them worked with PiP. But from 15 minutes footage, only ~5 minutes match in PiP.

    One would think, when one receives the question about multi-camera editing when creating a video, one would also receive a follow up question of which view is to be VIEW A and which is to be VIEW B. If a 3rd or more camera is involved that view should also be identified.

    Let the user specify the views, not the software.
