Also the encoding settings can change the size (for example xmediarecode didn't use same settings as default cli, file size was >2x the size). Container overhead can be that large (Check the elementary stream if you're doing that). And for a simple gradient, it is lossless (You can re-encode with CRF1 and PSNR is infinity)īe careful about just looking at the "filesize" only especially when it's just 1 frame, ~5Kb. "Lossless mode" isn't as widely supported in other programs, NLE's etc. Could you still please post your 10bit gradient test video here ? It's easy enough, even for beginners, to measure filesize and check for 10bit output in MediaInfo.Īlso why not use the encoder Lossless mode (x265 -lossless, x264 crf=0) ? I check end to end tests for various workflows (e.g. OK, I can imagine that the difficulty may in fact be analyzing the result rather than generating a gradient. Note on "real" content, the "ballooning" size won't be so drastic, but it's still suboptimal if you start with 10bit content Handbrake output >10x the size mainly because of the dithering, and gaps in the data (0,4,8) when you examine it. Handbrake "10bit" 2nd generation x265 crf 1 76kb
Handbrake "10bit" 2nd generation x264 crf 1 70kb Xmediarecode 10bit x264 2nd generation crf 1 (same settings) 5kb X264cli 10bit 2nd generation crf 1 5kb (output PSNR actually lossless CRF1) I think some GUI's like staxrip canĠ-1023 gradient original produced at crf1 5kb
Xmedia can preserve 10bit if you set it up correctly but I see no way of preserving the HDR metadata automatically. When you test - it dithers the intermediate stage (functions like noise to "hide" the banding), so it doesn't look as bad on a gradient as no dither - but the filesize balloons up because of the dithering Handbrake/vidcoder definitely uses an 8bit intermediate stage this is well documented. If there is an 8bit step, you will get gaps in the data such as 0,4,8, instead of 0,1,2,3,4,6,7,8, which of course results in more banding, less accuracy, worse compression Multiple highlighted jobs will all have the same conversion settings and multiple jobs will be added simultaneously.You can test it with a 10bit gradient. Supports batch processing when multiple videos are selected in the main interface (via ctrl+click or shift+click). A more detailed view can be accessed from the right click context menu for each video. Includes a Bitrate-Calculator that can calculate the required video bitrate to achieve a desired filesize based on various Media (CD, DVD, memory cards, etc.) Allows users to choose a percentage of the media for fine controlling.ĭisplays basic media info about each video using MediaInfo.
