ffmpeg doesn’t raccall it “you are missing a hwupload filter” but instead

Impossible to convert between the formats supported by the filter 'Parsed_format_5' and the filter 'auto_scale_2'
Link 'Parsed_format_5.default' -> 'auto_scale_2.default':
  src: nv12
  dst: nv12

and i think that is written in c and assembly lottehearts

the biggest travesty got to be the lack of reasonable video editing options like

i shouldn’t need to spend 15 minutes writing an ffmpeg filter chain translated form my NLE project just to get rendering times of something extremely simple to be faster than real time

the “extremely simple” thing btw is “put an image in the video in the bottom left corner and cut out part of the video”

what i came up with was

ffmpeg -init_hw_device vulkan=vk:0 -i /partition-root/old_roots/2026-03-05_09:10:28/home/darkkirb/2026-03-04\ 16-19-07.mp4 -i ~/Pictures/Art-bu/2025-11-22-wutatumaki-lotteholdingcinny-nopaci.png -filter_complex \
       "[0:v]trim=start_frame=0:end_frame=31476,setpts=PTS-STARTPTS[v1]; \
    [0:v]trim=start_frame=51758,setpts=PTS-STARTPTS[v2]; \
    [v1][v2]concat=n=2:v=1:a=0,format=nv12,hwupload[vfull]; \
    [1:v]format=nv12,hwupload[logo_gpu]; \
    [logo_gpu]scale_vulkan=w=600:h=600[logo_scaled]; \
    [vfull][logo_scaled]overlay_vulkan=x=10:y=830[vout]; \
    [0:a]atrim=start=0:end=419.667,asetpts=PTS-STARTPTS[a1]; \
    [0:a]atrim=start=690.107,asetpts=PTS-STARTPTS[a2]; \
    [a1][a2]concat=n=2:v=0:a=1[afull]" \
       -map "[vout]" -map "[afull]" \
       -c:v av1_vulkan -b:v 15M \
       -c:a libopus -b:a 128k out.mkv

@charlotte the gimp of videoediting

“it can theoretically do everything”

@twinkle well see

kdenlive and blender are honestly workable but they run so much slower than ffmpeg filter chains

@charlotte I’ve never not had kdenlive crash on me for the most rudimentary operation ever and I’ve never figured out how to do the most basic of things with it that it honestly feels less like a video editor but more a frontend to make a list of ffmpeg options (foreshadowing?)

blender at least works ig but like it’s not so much a videoeditor but rather “you could use it like one if you want” which means it also lacks the most basic operations but at least it doesn’t crash every 5 minutes

@charlotte blender is cool if your editing style permits using blender

mine doesn’t. the most I can use blender for is cinematics. I just don’t edit like that. tell me how to make a keyframed mask with blender videoediting and I’ll give you my dick and 20 dollars.

@charlotte “just mask whatever you wanted to mask in another software and export it to a transparency capable format” shut up the sole reason to have a competent videoeditor is to avoid that in the workflow
