  • 45 minute timeline takes 4 hours to render at 25fps!?

    Posted by Ola Haldor voll on October 4, 2011 at 7:24 pm

    I’m done with another TV episode. 45 minutes worth of footage. Rendering goes fine at 25-30fps, but the time left says “3h58min”. Ok? Where does that come from?

    I didn’t select to render with handles, nor is there anything extra on the timeline that shouldn’t be there.

    Any ideas?

    Are you rendering in “source” mode or target mode? Have you checked all your render settings? Are you rendering from the master timeline?

    Just some ideas…

    I selected the FCP XML roundtrip preset.
    Rendering from a session, not the master session.
    Array is 60% full.

    Hi Ola,

    How many frames did it say it was rendering?

    Did you have any variable speed changes in your project?

    does not seem to be any reason for that i could think of but array.

    generally you read and write on the same array which means 2x io speed.

    can you rule it out ?

    what is the format of the media? and i thought davinci was going to eliminate the need for rendering……i still prefer color when it comes to all the technical problems you can have with resolve! like rub gamut errors and wrong scale export…sheesh…i hope they take another look at color and steal a few more ideas form it!

    Kim – in order to create a new file, you will need to render. If I wanted to play out to tape, I could’ve just hit record on any deck and playout directly.

    The original media is Prores 422, 1920×1080 25fps
    I think I found the problem, but I have no solution. Speed adjustments. Variable speed adjustments. On a lot of the clips.. Makes Resolve render a lot more obviously, so it can go back to FCP with the proper roundtrip and all the speed adjustments, resizing+++ will be reapplied once back in FCP.
