Davinci Resolve change Timeline framerate
It’s impossible to change framerate for created timeline in Davinci Resolve. But I have one solution: you can find still frames by size (the 24th and 25th will be the same; and their sizes are same too).
- Render video as tiff sequence (or exr, no matter) and save it into ‘root/tmp/<image_sequence>.tiff’
- Redner audio as wav and save it to ‘root/out.wav’
- Download and put this script to ‘root/remover.py’
- Run script
- if you have whole black frames find its size in bytes and replace BLACK_FRAME_SIZE = 5124 to your size in script
- it will find consistent dublicates of frames and move it to ‘root/tmp/mv’
- It will rename all files after dublicate to fix hole in sequence names
- Make new project and insert your tiff sequence and audio into the timeline
Fullscreen playback Davinchi Resolve (little hack)
You don’t need to buy blackmagic hardware to make fullscreen playback 🙂
If you have 3 screens you can download this magnifier program (http://www.blacksunsoftware.com/screenmagnifier.html) and make third screen for its output! So, it will zoom you playback from small playback window to the third monitor.
I have only two screens and use it this way:
3D stereoscopic settings section is not visible / missing
1 To make Stereoscopic 3D appear in Nvidia Control and work.. you have to set your 3DTV as the PRIMARY display!!
2 Maybe you should to disable FastBoot in bios and turn on UEFI with CSM
3 Reinstall NVidia drivers with clean install checkbox
