Hey, I have some videos I'm trying to convert from mkv to mp4 (mpeg4 + AAC) for streaming, but it's not detecting the subtitles of the mkv files. When I open the source, the drop down menu only lists "foreign audio scan", however the original file definitely has embedded English subs that show up in vlc/mpv. This has happened once before, but I don't recall how I fixed it that time. Does anyone have advice?
Reddit’s internal media processor is incredibly rigid and basically throws a silent tantrum if a video isn't perfectly formatted. It's so picky and won't tell you how to fix it.
Are there any other conversion tool options aside from this one?
TLDR: Avg Bitrate of 10k, or RF 18 with 10k cap?
I know this has been asked time and time again but I have a specific question related to my personal settings I have.
I have a profile saved (1080p, x264, RF 18) that I use for encoding my rips that move onto a Jellyfin Server. This profile looks perfectly fine to me, but (for compatibility reasons) I have a bitrate cap set in Advanced Options (vbv-maxrate=10000:vbv-bufsize=10000).
There were certain devices that I came across that would force transcoding if the bitrate was too high (Gen 1 Chromecast, I've been doing this a while lol). That device had a streaming limit of 10Mb hence the Advance Option I set. I have routinely checked for updated responses but it still generally seems like a decent bitrate recommendation for 1080p blu rays range from 6k-10k, so i have not removed this and have just kept everything as is.
The question here is, would I get better results if I just threw the 10k into Avg with Multi Pass, or should I leave Constant with the cap?
That compression is phenomenal. https://www.techspot.com/news/112690-av2-promises-30-better-compression-than-av1-costs.html
**Edit, its crazy that its half the size of X265 for the same quality. Takes up roughly 40-55% less space.
Been pulling my hair out troubleshooting this issue and dozens of searches have come up empty.
I am running Handbrake on a recently built TrueNAS home server (specs below just in case they are relevant) that I installed via the TrueNAS apps catalogue. Have been encoding 1080p videos without issue (5-6 jobs) however, when attempting to encode any 4K videos, handbrake crashes. I saw another post where someone mentioned removing any additional encoding parameters and video filters, which made my crashes delay from almost immediately to ~2 minutes after starting the encode (enough to give me momentary hope). I've pasted below the activity log in hopes someone can tell me if it says what is happening. The only part that stands out to me is the repeated "set\_mempolicy: Operation not permitted" but googling that has not turned up any answers for me.
I also can confirm that there is nothing wrong with the video file, as Handbrake on my windows PC was able to encode the video (and other 4K videos just fine).

Just wondering, since space is an issue for me.
Pretty pissed I just bought a used GTX 1060 laptop only to find out about AV1 today. Especially since I cant encode AV1 using it.
When I choose Opus or AAC, I have the option to choose bitrate (I assume in kbps), but for Flac bitrate option is grayed out.
Before I encoded like this:
Video AV1 bitrate + Audio Opus bitrate = desired file size
and for that I would use one website to calculate file size by giving total bitrate and movie length. And it works flawlessly.
But I'm not sure how to do the same with with flac audio.
Does anybody know how to calculate file size for flac audio?
Edit: Dolby TrueHD -> Flac 16/24-bit stereo
Handbrake says that it auto-saves every subtitle track to .ass. When I check a processed file in MediaInfo, it reports that the subtitle is UTF-8. My understanding is that UTF-6 is the basic text, while the container is .ass. My Roku does not handle formatting cues correctly with this type of sub. If I use Subtitle Edit to "Save As" that subtitle and select ".ass", MediaInfo will now report it as ".ass" and my Roku will correctly display formatted text (such as top-of-screen alignment). I don't want to have to go through the extra steps of saving out every subtitle to ASS and then re-add it using MKV ToolNix. Is there a way to tell Handbrake to always Save As every subtitle to pure .ass?
My knowledge of Handbrake is fairly limited, so I apologize for the vague title. If there are any questions I can answer, please let me know
The GTX 1660 Mobile (6GB) or the GTX 1660 Ti Max-Q (6GB) Mobile.
I've received conflicting answers from multiple sources, so was wondering if anyone has hands down knowledge.
The laptops were talking about are a Microsoft Surface 2 GTX 1660 Mobile (6GB) vs Microsoft Surface 3 GTX 1660 Ti Max-Q (6GB)
I am using them for X265 NVENC 480p compression at 854×480 for my Uber and Lyft videos that are taking up too much space for cold storage.
I am sick of using my CPU for my second computer as my 940MX will not convert X265 only X264 NVEnc. I have a 4060 GPU on my Acer Nitro, (Which draws very little power) but don't want to hog up my main laptop all the time. Also, what would the FPS speed differences be between the GTA 1660's??
So, I have an mkv file that is 24:9 aspect ratio, but has black bars on top and bottom (16:9). Is there any way to just change the resolution from 1920x1080 to 1920x800 and keep the picture quality intact? Thanks.
As we get daily questions if encoding with GPUs will result in quality loss or why CPU-encodes are slower I quickly made this diagram. What would you change/rephrase before I pin it?
Hello,
I'm trying to transfer videos from digital8 tapes to a hard drive. I learned that you had to use the DV out to not lose quality so I used an old mac with a FireWire Port to record them with iMovie. It recorded to a .mov file so I wanted to use handbrake to convert it to mp4 but whichever setting I use, there is no audio on the resulting file.
I tried with AAC, AC3, MP3, Opus, PCM, PCM Passthru.
I also tried with MKV format instead of mp4 with AAC, AC3 and PCM Passthru.
The only setting that worked was MOV format with PCM passthru (because it didn't do anything I guess since that's what the file already was?)

( "decavcodec: hb_audio_resample_update() failed

I tried with DaVinci Resolve and it did gave me an mp4 with sound.
I saw online that handbrake didn't support PCM audio so it might be just that but I wanted to know if there was any way to make it work and maybe why it is not supported ?
Edit : Things that seem to work for people that could have the same issue...
1- MKVToolNix --> just drop the file and click "Start multiplexing". It converts instantly to a MKV that you can put through Handbrake.
2- Shutter Encoder Replace audio function -> check convert, use PCM or Vorbis and click "start function", then through Handbrake.
3- Avidemux -> Just put the output format as AVI and save. It is really quick.
That's the 3 fast options I found so far that solved the handbrake compatibility issue with the 4 PCM audio channels. I still don't know why though and would be interested to know.
And lastly : This is the first and last time of my life I will touch a Macbook!!
So this is my current settings (ignore the file I know it's a high grain file most other anime don't even come close with grain).
I have all filters off and every anime is straight from the Blu Ray Disc (even the ones that have all episodes as one file and become a pain to split.
I am currently watching though season 2 of SAO and am noticing slight grain floating around objects. Of the first 5 episodes done It's been 520-730MB files which is fine, is there any setting worth changing other than tune grain and CQ?
(Tune grain noticeably bloats file size and from testing most the time I am better using a lower CQ for better overall quality)
Generally my goal is to keep the file size under 1GB per episode where I increase quality. And I am asking before I do all the anime I have 😂. The 540 in my queue is the rest of season 2 and live action movies that I seem to be fine on.
I am trying to encode footage that I captured with my action camera (DJI Action 5 Pro), but the bitrate on the encodes is much higher than the original files. Are there settings/tweaks I can use with x265 to get my bitrates down to 15-25 MB/s while preserving most of the detail and avoiding heavy artifacts?
I have tried CRF values from 18 to 26 and still get huge encodes, bigger than the original. At CRF 26 I am starting to notice quality degradation and the bitrate is higher than the source. I have also tried 2-pass, with ABR between 15 to 30 MB/s. Even at 30 MB/s there are noticeable artifacts and quality degradation.
Here is a short sample of the footage I am trying to encode.
I usually encode my media to store on NAS using H.265, but to be more efficient as i thought i tried AV1.
Everywhere I hear that AV1 should be at leas somewhat better than H.265, but no matter what i tried (including building custom FFMPEG with VHQ tune for AV1), i get filesizes nearly doubling what H.265 does.
As for quality they are the same, and i mean it, you wouldn't be able to tell which one is which.
Am i doing something wrong?
Also just to clear things up, I strictly talking about NVEnc and not software encoders.
EDIT:
I guess the post doesn't clarify on what actual question is. It isn't about how to encode videos, it is strictly about NVEnc's implementation of AV1.
What i wanted to actually know Is NVEnc's AV1 just significantly worse than NVEnc's H.265, or am I missing something?
Additionally to every reply saying "Just use SVT" I re-ran vmaf:
Nvenc H.265 (slowest, CQ 27):
~3 minutes
339 MB file
median vmaf against original: 91.899171
Nvenc AV1 (slowest, CQ 27):
~2 minutes
638 MB file
median vmaf against original: 93.456927
AV1-SVT (Preset 2, RF 30, tune vq):
took 55 minutes
263 MB file
median vmaf against original: 92.321889
Those results are with 5070 ti which would allow me to do two separate h.265/AV1 encodes at the same time so it would nearly half encoding time then encoding more than one file at a time, which I usually do.
As for SVT, it is done on Ryzen 5700x (8/16) with PBO so it is barely throttling during multicore tasks, and it produced file 100 mb smaller at the price of doing a video for x30 time even compared to single threaded encode with NVEnc, so with multi threaded encode again, double it.
As for CQ not scaling equally across different codecs, it actually does. It is litteraly scales even between different encoders, I did test Nvenc vs VideoToolBox same CQ means extremely similar vmaf results. CQ is not the same as RF, RF does scale differently but CQ is basically a quality target.
I don't have so much time to wait for single file to be processed then at the same time I could finish 40.
I'm converting my physical media to digital specifically anime (super annoying).
I have broken out the episodes and have 6 audio tracks. I want to keep the DTS-HD MA for both english and Japanese.
on disc they are
I prefer to keep the dts ha ma for both english (1) and japanese(5) with the japanese moved to become track one after the encode.
How do i do this?
I can set "use first track as template"
Track selection behaviours "first selected language" (add japanese first over english)
but this puts japanese (3) as the track to encode? is their an option somewhere that i'm not using correct or another feature that allows me to encode this with track 5 first then 1 as second without doing it manually?
EDIT:
I could start over again and in the process of splitting the episodes apart with mkvtoolnix i can remove the extraneous audio tracks, but i have already purged the disc rips which means restarting for this series.
Audio/Video friends:
Anyone know the fastest/most affordable option for transferring MiniDV tapes to a digital format? I’ve tried doing it myself and it just takes too much time. Most other options I’ve found cost a fortune to transfer and take months to get back. (I have a ton of tapes). Shoot me some ideas!
I use this preset on everything 4k and have never had this issue. I don't know why. The output is seemingly cropped with black bars on the left and right when viewing in VLC. Changing anamorphic to auto (even though I want it off) and checking allow upscaling at the same time will set the final dimensions to the correct 3840x2160 16:9 aspect ratio, but there are still black bars, at least when I did a preview with those settings.
Any advice on what I'm doing wrong here or what the issue could be would be greatly appreciated.
