RVRetime explicit frame numbering

Hi there, I'm trying to understand how the frame numbering is supposed to work in the explicit retime mode. Say I have a source movie of 4 frames (1-4) and I want to retime it to 101-108 (so offset by 100 frames and half the speed). 

I set .explicit.firstOutputFrame to 101, then set .explicit.inputFrames to [1, 1, 2, 2, 3, 3, 4, 4] (and set .explicit.active to 1)

This does the frame doubling correctly, but in the timeline the frames are still numbered 1, 1, 2, 2 etc. I would like them to be 101, 102, 103, 104 etc.

How would I go about this?

 

Cheers,

Anders

    Hi Anders,

    I don't think there is a way to tell RV to identify a frame by a number name that way. Are you looking at source frame numbers or global frame numbers on your timeline. You can check by right clicking on the timeline widget.

    Thanks,
    Jon

    Hi Jon, I didn't realise you could do that with the timeline, thanks! It was source frame numbers, but global doesn't do what I want either. Continuing with my example above, global frame numbers show 1,2,3,4,5,6,7,8. I've also tried using the .visual.offset to offset the frame numbers and that has no effect either. I'm a little confused about what .visual.offset and .explicit.firstOutputFrame are supposed to do, since they just seem to be being ignored?

     

    Cheers,

    ...aaand just realised after running through the docs again that what I actually want is the .group.rangeOffset on the RVFileSource node to do the offset, then to use the RVRetime node just to do the time warp.

    Hi Andres,

    Sorry about that. Do you think you can send us a sample session that you have assembled?

    Thanks,
    Jon

    Hi Jon, I'm afraid I can't easily supply a session file. I managed to do what I want with the explicit retime mode and using the .group.rangeOffset on the RVFileSource. My confusion stemmed from the fact that I was expecting .explicit.firstOutputFrame to do what .group.rangeOffset does. The use case for this is playing and stacking movies with differing "step" values - i.e. renders that have been generated on every second, fifth or Xth frame compared to a reference movie where every frame is present.
