![]() 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 ![]() PS I'm happy to choose another remuxing tool (windows based if possible) if XMedia-Recode has a known deficiency here.You can test it with a 10bit gradient. I see lots of posts talking about how you can import 'srt' files, etc, but my subtitles are already contained within the MKV file, so they aren't importable. mp4 file, and choose 'subtitle'/sub-track-Track 1 (English), I see just 'chapter (x)' in the place where subtitles should appear. If I do choose just one subtitle, and do the remux, then when I play the resulting. I don't actually NEED more than just the English subtitle in this case, so I don't specifically care that I can't add multiple, but the bigger issue is the problem that the subtitles aren't appearing in the output. The only options on the subtitle tab are Mode: "Render" and Codec: MOV text. I can select one of these, then click the 'right arrow' to send it to the output side, but when I choose the second subtitle on the left, and click the 'right arrow', it REPLACES the item on the right, rather than adding to the list. In XMedia-Recode, I set video and audio to 'copy', and on the 'subtitle' tab, all the subtitles show on the left (eg, 1. This works great (the remux only takes seconds) and the video plays well in iTunes/on the Apple TV. I've used Xmedia-Recode to remux the MKV movies into MP4 movies (also tried MOV, same results). I rip the subtitles in such a way that they are selectable that is, I don't 'burn' them into the video I can turn them off/on at will and I believe the correct term is, they are an 'overlay'.īut now I have an Apple TV and want to play my movies on it, 'streaming' from iTunes on my MacBook. When I rip using Handbrake, I make sure to get all the subtitle tracks over, and they are fully functional in the MKV file when I play them in VLC, and in various other tools (including Western Digital LiveTV player). My partner is deaf and we rely heavily on subtitles. I have a huge library of movies originally ripped to MKV using Handbrake. Hello everyone - it's been a while since I was here!
