@VeronicaExplains made a great video that covers kdenlive, too! • I make all my videos using Linux. Here’s how.
all footage incl. pixel animations is mine.
my wallpaper is a painting by Alois Arnegger ‘winter mountain landscape in evening light’.
Yeh, either proxy editing (where it’s low res versions until export).
Or you could try a more suitable intermediary codec.
I presume you are editing h.264 or something else with “temporal compression”. Essentially there are a few full frames every second, and the other frames are stored as changes. Massively reduces file size, but makes random access expensive as hell.
Something like ProRes, DNxHD… I’m sure there are more. They store every frame, so decoding doesn’t require loading the last full frame and applying the changes to the current frame.
You will end up with massive files (compared to h.264 etc), but they should run a lot better for editing.
And they are lossless, so you convert source footage then just work away.
Really high res projects will combine both of these. Proxy editing with intermediary codecs
