You decide which tradeoffs you want to make. But the decoding latency and scrub times suffer. Available Encoders Current H. Now you can use ffmpeg directly to encode HEVC or use another encoder then manually mux that into. Short GOP’s on average will cut the size in ~1/2. FFmpeg supports encoding HEVC/H.265 since with libx265. An installation of FFmpeg compiled against this version of x265 can produce a decent 10bit encode with the following command: ffmpeg -i input.mp4 \ -c:v libx265 -preset medium -crf 28 -pixfmt yuv420p10le \ -c:a aac -b:a 128k \ output10bit.mp4 And this should see you through. 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. I might be wrong, but I think it could support x265 codec, which is one of the. Basically the largest filesize possible and yet still be losslessly compressed by x264 I know Blender already uses FFMPEG according to its video encoding options. 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. default one: ffmpeg -c:v hevccuvid -i h265file.mkv. An IDR frame is a self-contained frame that does not require any other frames to decode the image correctly and it only contains I-slices. Prior I used cineform at half resolution as editing proxy files are still big if lossless. First of all, your compile of ffmpeg needs to support cuvid decoding. Instantaneous Decoder Refresh (IDR) frames are critical reference frames in video encoding, often used in H.264/AVC and H.265/HEVC codecs. 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.
