![]() ![]() Or, what kind of problems do you have in the process of changing the color space to 0-255 when RGB treatment becomes available?Īnd if level clipping occurs, what does it result in? I wonder how the image captured by YUV exceeds the color space of YUV. What exactly does it mean to beyond the y value, CbCr value? Let's assume that editing is carried out with HuffYUV video. So I think I need to edit it with cineform, DNxHD, or HuffYUV CODEC, ![]() (It is said that ffmpeg is also possible, but I heard that it is not an official codec, so there may be problems when playing or editing.) Huffyuv (Capture) -> 422 HQ (Edit) -> h.264 (Upload)Īlso some PP point releases treat lossless x264 as YUV (truly lossless)Įxcept for Adobe, it seems that it is impossible to encode Prores CODEC in Windows os. Not to the point of editing with uncompressed UYVY? However, if the image quality deterioration due to 2-3 encoding processes is meaningless, it would be fine. I tried not to make it worse because Hi8 itself is already a lo-fi video. In addition, I understand that loss encoding will proceed once more when uploaded to YouTube. I'm making a music video.Īs far as I know, if you encode several times, the video will get worse. They take up less space and edit performance very fast (decoding /scrubbing fast). Otherwise, near lossless intermediates like cineform, prores, dnxhr/dnxhd are typically used. Hi8 isn't going to be great quality, and if you ensure you adjust the capture to legal levels, it can work ok If you import huffyuv or those others, you will get RGB treatment, and clipping (if your capture has Y values beyond 16-235, or CbCr values beyond 16-240). People typically use uncompressed UYVY in Adobe if they need true lossless if using 8bit. Is something like prores hq or "near lossless", "good enough" for what you are doing ? What workflow do people usually go through when capturing tapes and editing in Adobe PP? I wonder if it's right to go through this workflow. In conclusion, it is one or two encoding processes. Lossless capture( huffyuv or something) -> edit in PP(with lossless or prores 422 HQ) -> edit -> h.264 The first workflow that I thought of is as follows. I don't know if what I understand is correct. Should I use the uncompressed UYVY 422 8bit codec? You need lots of fast HDD or SSD room for uncompressed, but SD isn't too bad compared to HD/UHDĪlso some PP point releases treat lossless x264 as YUV (truly lossless) I googled and found out that 10 bits in Hi8 doesn't mean anythingĪs you said If x264 is treated as lossless in some releases, The problem is most "lossless" YUV codecs get converted to RGB and not treated as YUV (thus they are not "lossless" in PP there can be levels clipping during the limited range YUV conversion to full range RGB), and aspect ratio info isn't automatically conveyed (AR easy to fix by group selecting and interpreting files)įor 8bit 4:2:2, UYVY uncompressed 8bit is treated as lossless YUV, or for 10bit 4:2:2 uncompressed, v210 in all versions of PP. ![]()
