Convert to AV1 format using ab-av1
-
@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.

@MrMazda Thanks for the detailed explanation. To be honest, though, I still don't understand if an .mkv is considered a different format to an .mp4.
Assuming they're otherwise the same, but one torrent contains a single .mkv file with soft coded English and French subs, while the other torrent contains three files - 1 x .mp4, 1x .en.srt, and 1x .fr.srt, are they duplicates?
I get that if the .mkv contains four set of subs - English, French, Chinese and Thai - then it isn't, but that it's the responsibility of the uploader to make any differences clear in the description to help mods, but if in the former case they're considered duplicates, I feel this should be made clear in the "rules". I'm sure I'm not alone in simply assuming - until now - that if the file type is different, it's a different format.
Other opinions are also available. They're not right, obviously, but they are available.

@Kevin4fm In this case, it would not be a dupe, as the subs in a way are built into a single file, along with the video. It is only when the files are separate that it becomes a dupe.

MKV Format
MKV, short for Matroska Video, is an open-source container format that was developed with flexibility and extensibility in mind. Unlike proprietary formats, MKV allows developers to freely use it without licensing fees, making it popular in open-source projects and media preservation.MP4 File Format
MP4, short for MPEG-4 Part 14, is one of the most widely adopted video container formats, developed based on the QuickTime File Format. It is the industry-standard container for video, particularly for web streaming and distribution due to its widespread support across devices, platforms, and browsers.OVERVIEW :
- https://api.video/blog/video-trends/mkv-vs-mp4/
- https://www.elmedia-video-player.com/blog/mkv-vs-mp4/
The Most Common Video Formats
- MP4 (MPEG-4): The most popular video format in the world. It is universally supported by almost all devices, web browsers, and social media platforms like YouTube and Facebook.
- MOV (QuickTime Movie): Developed by Apple for QuickTime. It is a high-quality format primarily used by video editors working in macOS and iOS environments.
- MKV (Matroska): A highly flexible, open-source format ideal for archiving movies and TV shows. It can hold unlimited video, audio, and subtitle tracks in a single file but isn't as universally supported by mobile devices.WebM: Developed by Google, this format is specifically designed for
- HTML5 web streaming. It yields excellent quality at small file sizes, making it a favorite for web developers.
- AVI (Audio Video Interleave): One of the oldest formats, developed by Microsoft. It can provide high-quality uncompressed video but results in very large file sizes.
- WMV (Windows Media Video): Created by Microsoft, this format is highly optimized for the Windows ecosystem. It is generally less compatible with Apple or mobile devices without third-party converters.
Containers vs. Codecs
When discussing video formats, it is also essential to know the difference between a container and a codec:- Container: The file extension (e.g., .mp4, .mov, .mkv) that acts as a wrapper holding your data together.
- Codec: The compression/decompression algorithm used to shrink and encode the actual video and audio data inside the container (e.g., H.264, H.265/HEVC, AV1).
So the rules should be :
A file is considered a duplicate if an existing torrent has the different (same) format and similar size (<10% difference) and has at least one seeder. -
In these case : let's consider
Dell, HP, Lenovo, Apple, ASUS, Alienware, MSI are all they same
SMH(Even if different type of company, manufacturer, distributor, retailer, product, vendor and brands etc... ) ...

@john32123666 OK. These are technical differences, and very well explained. Thank you. But I'm specifically talking about / asking about how they're considered here. In your explanation, you state
The Most Common Video Formats...
MP4 (MPEG-4): The most popular video format in the world. I...
MOV (QuickTime Movie): Developed by Apple fo...
MKV (Matroska): A highly flexible, open-source format....So a surface read of this says that .mkv files ARE a different format to .mp4, as are .avi, .wmv, .mov, etc.
Yet my experience is that they're treated here as being the same as .mp4, unlike the other formats. A 1080p .mkv video file with hard coded English subs will be considered a duplicate of a similarly sized 1080p .mp4 file that also has hard coded English subs. This doesn't seem to be the case with other formats, such as .wmv or .avi.
Perhaps different people have different understanding of what is meant by "format", which I've assumed to be file type, as opposed to 1080p/720p/480p, which I understand as "resolution".
What it comes down to is whether a .mkv file that's identical in every other way to a .mp4 file is a duplicate. And, if it is, why doesn't the same hold true for .avi, .wmv, etc.? Or does it, and I've not yet come across an example of it? In which case, the guide note for duplicates should read "resolution", not "format", or have an explanatory qualifier "...format (i.e. 1080p, 720p, etc.)".

@Kevin4fm IDK I think they evaluate different format with resolution type not on format container ...

Topic is wrong : Convert to AV1 format using ab-av1
shoulde be codec ...AV1 is a codec, not a file format. It stands for AOMedia Video 1 and is a highly efficient, royalty-free video compression algorithm developed by the Alliance for Open Media to stream high-quality video over the internet.
-
IDK I think they evaluate different format with resolution type not on format container ...
@john32123666 Nope, not in my experience. And that's my point. Clear advice / guidelines are needed, not ambiguity or the possibility of different interpretations depending on who is making the decision.
Other opinions are also available. They're not right, obviously, but they are available.
-
@Kevin4fm that's kind of stubborn answer ...
They are MOD and staff and we are only users ...
So the they have the rights to evaluate things ... -
@Kevin4fm so @ work you listen to your co-workers instead of your supervisors and if they tell you to jump you will also jump ...
-
@john32123666 I'm not sure I get you point but, sticking with your analogy, I'm asking that the supervisors / decision makers give clearer, more explicit guidelines.

@Kevin4fm so you're not sure ,,, SEE

These is getting way too far Kevin, all yours ...

get the hell out of here with that stupid ass off-topic discussion please
Given that the very first sentence that started this thread was "what are these? its a reupload of same file but little smaller. whats the point of this? [Convert to AV1 format using ab-av1]", I don't believe a discussion of what is, and is not, considered a duplicate and why that is, is "off-topic".
