Activity Forums DaVinci Resolve Render only changed clips

    Hi Guys,
    I did the grading on a 44 min show in Resolve 8.1.1. I then rendered everything to prores clips for approval in FCP7. The director wants me to adjust some clips. Is there a way to go back to Resolve, change some grades and only render those clips?

    Yeah, wouldnt it be great that function that warns you you are using the same folder for a render would actually give you an option to skip or overwrite files ?
    Rendered clips also should be used as cache files and as soon as you touch the grading , they would go back to interactive mode.

    Amen! Where do we send our request for this feature to be escalated in the list for next version. It would be so much more efficient.

    You mean import the rendered files and shine though the current timeline until you touch the grade where then the ungraded clip with the current grade becomes active again?
    This could be messy and confusing for some…?

    What if there was a simple way to reset the VSR rainbow on the timeline thats shows shots have been graded..
    You could then open up an old session, reset the rainbow and only newly tweaked shots would then be highlighted.. In the render page you could easily see which ones need re-rendering.

    Exactly. I also would love to see this.

    Its works like that in other systems..
    Call it : Process on Play for example.
    Whenever you play through something once, it could write the images to disk.
    Or when you execute a full render it would do that without real-time playback.
    The cache is DPX ( should be EXR ) and should be kept until you decide to flush it.
    When you set the timeline to cache its a little like that, interactive, in the BG , but flaky and unpredictable.
    Also you loose it all when closing or changing projects.
    So what if you could do the opposite, initiate a full render to a useful file sequence and play those files on the timeline instead of the source plus grading.
    Only until you touch a slider of course.

    Not sure anyone answered your question directly – If you’re using the FCP or Avid preset, you can render any indvidual clip. I think you could use like… mark for render cache… or something to mark clips you NEED to render if your director doesn’t want to wait for each render… it does seem like there should be a way at least automatically flag clips that have been changed since render…

    The thing is that with linked clips a change on a clip will affect more than the selected clips. And you can’t group-select clips for render. ANd then, when you export the XML for roundtrip Resolve is all messed up in what folder the renders are.
