Convert to AV1 format using ab-av1
-
AI Overview
Using ab-av1 auto-encode to compare HEVC (x265) and AVC (x264) against AV1 (libsvtav1) reveals stark differences in efficiency, encoding time, and hardware compatibility. Ultimately, AV1 is the king of efficiency, x265 delivers great size reductions with mature compatibility, and x264 remains the universal playback standard.A detailed breakdown highlights the exact differences when these encoders are managed by ab-av1's VMAF-based auto-encoding:Key Encoders & Their RolesAV1 (via libsvtav1): The next-gen benchmark. It delivers roughly 30% to 50% better compression than HEVC. Using ab-av1's auto-encoding ensures you target a specific VMAF (Video Multimethod Assessment Fusion) score without wasting bits.Pros: Best quality-to-bitrate ratio; fully royalty-free.Cons: Requires the longest encoding times compared to the others.HEVC (via libx265): The reigning champion of compression before AV1 matured. It is widely supported by modern hardware, making it excellent for long-term archiving.Pros: Very efficient; much faster to encode than AV1.Cons: Tangled patent licensing; can sometimes smooth out fine film grain.AVC (via libx264): The industry's baseline. Almost every device—including old phones, tablets, and web browsers—can decode x264 seamlessly.Pros: Instant encoding; universal compatibility.Cons: Requires much higher bitrates to achieve the same visual fidelity as HEVC or AV1.How They Stack UpFeature / MetricAV1 (libsvtav1)HEVC (libx265)AVC (libx264)Bitrate EfficiencyExceptional (Best)Very HighBaselineab-av1 Auto-Encode UtilityPerfect for locking in VMAF targets without manual mathGreat, but requires fractional CRF values for precisionGreat for legacy targetsEncoding Time (Speed)Slowest (Can take 5-10x longer than H.264)ModerateFastestHardware CompatibilityModern Devices OnlyWidely SupportedUniversalWhat this means for ab-av1 auto-encodeWhen you use ab-av1, the tool dynamically searches for the perfect Constant Rate Factor (CRF) to hit your minimum VMAF target.If your priority is future-proofing and storage space (and you have a modern TV or PC), use AV1.If your priority is device compatibility without huge file sizes (e.g., streaming to an older iPad), use x265 (HEVC).If your priority is universal compatibility for sharing with anyone, use x264. -
It's good compare to [hevcx265 w/c takes a lot of resources]
I downloaded one of his re-encode work, however he prefers MKV format ...plays faster, quality is almost they same compare to original size ...

Tagging @mrmazda and @kalayaan to make this a more contextualized report, they can check if both torrents were uploaded by the same person.
Ultimately what's more important is that both torrents are photo collections and most files are 100% duplicates, the video files are the only difference.
Also you guys need to chill on those AI overviews, it's getting out of hand.

...A file is considered a duplicate if an existing torrent has the same format and similar size (<10% difference) and has at least one seeder.
@john32123666 I've had two, or maybe three, torrents that I've uploaded removed as duplicates where the original was .mp4 and mine were .mkv. These are - or at least in my case were - considered by the powers that be to be the same format.
And these weren't uploads made within days of each other, but many weeks / several months later.
Other opinions are also available. They're not right, obviously, but they are available.

@john32123666 Why is it useless? When something is spotted, you simply report it using the link specifically for that purpose. And, assuming it actually is a duplicate, the person reporting it gets a 50pt seed bonus. They're harder to spot, of course, when someone decides to use a different title and/or file name, and I do sometimes wonder if this is deliberate.
I would say, though, for such an 'important' rule, it's not particularly well defined. I've read it multiple times both before and after uploading a torrent deemed a duplicate and other than the .mp4 : .mkv issue - which is not mentioned - I still contend they weren't duplicates. Except one where the original was a dead torrent, rechecked over more than a week before uploading, where the original uploader (or someone) subsequently seeded it, so mine was judged to be the duplicate.

I've had conversations with moderators following the 'duplicate' takedowns. One was considered a duplicate even though the .mkv file had a softcoded subtitle track not included in the .mp4 + .srt version. With another, I was specifically told that .mkv and .mp4 are not considered different formats.

No, MKV and MP4 are not the same file format. While they are both "container formats" that hold video, audio, and subtitle data, they differ significantly in their compatibility and features.
M4V: Developed by Apple, this is essentially identical to an MP4 but often includes digital rights management (DRM) for copy protection.
-
@john32123666 I agree, but I'm not the arbiter. I was told by a moderator they are, and that was why my torrent was deleted.

We'll have to agree to disagree on that then. A rule is only pointless if it is both ignored AND not enforced. I know both from personal experience, and from seeing torrents I've grabbed and was seeding suddenly disappear, that it most definitely IS enforced. That simply takes someone spotting it, and taking thirty seconds to report it.

well i dont judge and i didnt even report it. i just asked why... if the difference in size were +50% then i would understand why they did it
also the mkv reuploader even included the original link if someone wants that in mp4
which is nice of him -
@jokuihmemies i judge
that mf had me create a new filter for all my rss feed entries to avoid automatically downloading that garbage, if this is allowed then it's time to change the rules! -

In a case like that, then it's a different ball of wax. If there is a distinguishable difference in the content, then it is not a duplicate, even if the format container is the same and the size difference is less than 10%
For example, if one of the uploads is only 720p, but the other is 1080p (or 4k vs 5k), then it is not a duplicate. If one version has subtitles built into the video itself, but the other is just the video itself as is, or has subtitles in a different language (built into the video file itself), then it is not a duplicate. If both versions of the video itself have the same audio and subtitles, but one is built into the video itself, and the other is the standalone videos as is with a separate .srt file, then it is not a duplicate. When it comes to adding picture sets or other .srt files, generally it is accepted as a dupe if the video file itself is the same, but the only difference is the .srt. This is most especially true if the video file itself is just the video with the same audio, is less than 10% different, and does not contain any subs at all. You can however add subs as a separate torrent and reference the torrent they belong to in the description so users can piece them together themselves.
MKV is a bit of an oddball thing as far as I understand it. As it was explained to me, MKV can consist of any number of format containers within a package essentially, so it becomes a bit more challenging to define. There is a lot of inconsistency in that regard when it comes to MKV.
The biggest key to not getting zapped as a dupe in error when the size difference is less than 10% is to be specific about the specs of the video, and if the specs aren't clear in the description of what would be the original torrent but you know them to be different, then it always helps to reference the original in the description of your upload and explain the difference.
If the specs (like resolution, subtitles, etc) are not specified in both of the uploads, then the only thing we really have to go on when reviewing the report is the format container and size difference.... So the more specifics you can give, the better.

@MrMazda Fair points, which I'll ensure I take onboard next time I upload something that could, at a simple first glance, be so considered.
I've only had three struck down out of more than two hundred, though most of these were obviously not duplicates of course. Only one of these (I think) was genuinely a duplicate - based on .mkv = .mp4. The others weren't, and I was told "well they are", even after I pointed out WHY they weren't after they'd been deleted. But I'm sure moderators et al have enough to do without getting bogged down in discussions like that, so I'll just take your advice in future and make it very clear why my torrent is not a duplicate of another, even if it might appear to be at first glance.
I do think, though, that clear guidance on the .mkv issue should be included in the upload rule. Either it is a duplicate or it isn't. If it is, is it only .mp4 that it might be a duplicate of? Is it a duplicate if it's a single file containing multiple softcoded subs, and the other is .mp4 with no softcoded subs but half-a-dozen .srt files - matching what's softcoded in the .mkv - included in the torrent?
-
@Kevin4fm a mod cannot make decisions based on the container alone, because being MKV doesn't equal to having soft-coded subs. For example take a MP4 movie, add chapters marking each scene and make it a MKV, the video stream is 100% identical, but one has a thing that the other doesn't... And still the file sizes are virtually identical. Would that be a duplicate? If you ask me, I have no fucking idea, glad I'm not a mod
Because the duplicate rule is for very simple cases, it must be extrapolated for edge cases, and mods will inevitably resort to their own discretion to decide. One mod probably would delete what another wouldn't, following the exact same rule, like a soccer referee.
-
@ianfontinell I agree for the most part. The simple instruction to include, clearly why "this" .mkv is different to "that" .mp4 + .gb.srt + .sp.srt + fr.srt is reasonable, especially given a mod needs to be able to make that determination fairly quickly, and other things - size, resolution, etc. - might otherwise make it look so.
My "issue" is that I suspect many, as I did, will start from the basis that a .mkv containing softcoded English and Chinese dubs, all in one file, is a different format - and therefore not a duplicate - of a torrent containing a .mp4 + those two .srt subs.
I do, though, feel there should be a clear note in the definition of "duplicate" that an .mkv IS considered a duplicate of a .mp4, UNLESS it contains additional elements not included in the original torrent, and that these differences should be clearly stated.

With the exception of MKV (which is a whole breed of file all unto itself), it is generally considered a duplicate as long as the video itself is the same and is within 10%.
This means that if one is the video file itself, and the other is the video file with different SRT files added, then it would be a duplicate. The exception here is when the subtitles are built into the video file itself all as one file. When the subtitles are built into the video file, then there is a distinguishable difference between the version that is just the normal video and the video file that has the subtitles built in. It is the same if there are two video files where the subtitles are built in, but are in different languages. When the subtitles are in different languages AND are built into the video file itself, then it is NOT a dupe, even if the format container is the same and the difference is less than 10%. The same goes for when the audio track is in a different language, particularly for themed movies. If the audio of one is in English and the other video has its audio track in a different language, then despite it being the same video otherwise, there is a distinguishable difference.... The audio language.
As for challenging the removal of a dupe, this is something you absolutely are able to do, but there is only a limited amount of time in which to do so before the upload is fully deleted, and you must make sure to do so respectfully. If we (or at least I) have made a mistake, pointing out why you think it's a mistake can lead to the torrent being restored. After all, just like anyone else, mods are only human, so we do get it wrong sometimes too.
On that note, if a mod does get it wrong, pointing out the error is not a problem. In fact, mods like myself actually appreciate when users take the time to point out something that we missed, as this helps us to not make the same mistake again in the future. As long as you point out your objection in a civil and respectful manner, you will not be penalized for it. The absolute worst thing that will happen is we will have to agree to disagree and move on. It is only when you get nasty and do things like lay personal attacks or otherwise hurl insults that you could get into trouble for it. Keeping things to the point, and more specifically, to the facts is often your best bet with this.
The worst case is if you don't raise the objection in time or the mod does not go to review it before your upload is fully deleted, you may just need to upload your torrent again. If this happens, just make sure to be specific about what difference(s) there are between the two files, especially if these differences were overlooked the first time.
Most mods will at least give you a fair chance to explain yourself and/or your situation before making a decision on most things, just in case there is something for which we may be unaware. I do this myself for most things. So don't be afraid to point out when we (or at least I) get it wrong. Sometimes a different perspective is all it takes to open our eyes to something we have either overlooked, or otherwise never thought to take into account.
