You decide which tradeoffs you want to make. But the decoding latency and scrub times suffer. Short GOP’s on average will cut the size in ~1/2. Cineform is a “visually” lossy codec, and usually only the subsampled variant is used (10bit422). If you think cineform at half resolution was large in filesize, these files will be much (!) larger than cineform even at full resolution. Basically the largest filesize possible and yet still be losslessly compressed by x264 Lower values mean better quality but longer conversion times. The settings you specified are making it “less” compressed, easier to decode. (You might need a higher quality and resolution proxy if you were doing delicate work, and needed to zoom in for accurate placements, those sorts of reason)īut lossless compression won’t produce something “lowsize”, and certainly not with intra encoding. You swap back the originals for final quality export. The are just there to make editing easier. Proxy files don’t need to be lossless or high quality.
Prior I used cineform at half resolution as editing proxy files are still big if lossless.
Hence a Lossless with compression but relatively easy to decode. I knew about proxy I wanted to try if I could create a “one size fits all” file, storage/editing/lowsize.
