Bug ID: 426134
Summary: MELT.EXE can support GPU if enabled
Product: kdenlive
Version: git-master
Platform: Microsoft Windows
OS: Microsoft Windows
Status: REPORTED
Severity: wishlist
Priority: NOR
Component: Video Display & Export
Assignee: j...@kdenlive.org
Reporter: pe...@whisker.org.uk
Target Milestone: ---
SUMMARY
Swapping the version of melt.exe for that supplied with Shotcut (C:/Program
Files/Shotcut/melt.exe) allows GPU rendering
STEPS TO REPRODUCE
1. Swap melt.exe as above (I also swap the three ffmpeg executables for
consistency)
2. Create custom profile (see below in Additional Information)
3. Render in half the time using GPU
OBSERVED RESULT
This is a request that the Kdenlive shipped version of melt.exe has the libav
hardware based encoders enabled by default to avoid having to swap the binary.
GPU rendering on my Intel UHD 620 works very well and is a lot faster.
EXPECTED RESULT
