By making the player display them on the fly? Yes, you can. Some players allow you to set how a file should be displayed. For instance, for SD files on Omneon, not only you can add the 4:3 or 16:9 tag, but you can also add whether it should display black bars or crop. This information will be added into the .mxf container and it will be read by any player that supports it. The problem with this is that if you do something like this there's no guarantee that it will work and only a few players will honour that and definitely not consumer players given that it's mxf. A more consumer friendly alternative would be to do this with MKVToolnix which allows you to set the aspect ratio and cropping parameters at container level. When the file plays, the player should read those values and apply the scaling on the fly, however this is not really very widespread either. I think it would be much better to re-encode, but if you insist on doing this without re-encoding, your best shot is MKVToolnix. |

Just about any software player will automatically add black bars, depending on the aspect ratio of the content and the display screen. Same goes for hardware play back devices.

In short... No!
Why do you need to add black bars. What device are you using to play your files?

VLC player offers the ability to add black bars automatically.
If this isn't happening it must mean your sources have not been encoded correctly. With this in mind please run one of your problem sources through an application called MediaInfo, which must be set to text mode and post what it reports 'in full' as a text file.

You'll need to provide an example.
Personally I have dozens (720x480 and 720x576) of image only (ie: black border cropped) DVD back-ups on my NAS that are displayed perfectly on my 65" TV. Lol... When this forum started (over 20 years ago), we all cropped the black borders from our DVD back-ups!

Ah no, not adding. Looks like it's only supported in the Omneon Muxer and mxf container... what a bummer. I really thought MKV would support this 'cause mkv as a container generally supports (almost) literally anything...

It might just be a case of changing aspect ratio in container[sources have not been encoded correctly], OR, just using correct settings in player. Post output of MediaInfo.

For cases where a container option don't help, mpv supports file specific configuration files:
https://mpv.io/manual/master/#file-s...guration-files In such a file, filters can be defined: https://mpv.io/manual/master/#video-filters It's not completely easy to learn how to use mpv, a good place to ask questions is Reddit: https://www.reddit.com/r/mpv

That's because your video has a 2.472 aspect ratio, of course any player will automatically add black bars when using a large window.
However, the video's width is maximal and my goal is to limit it and force it permanently to 16:9 aspect ratio by black bars. (I use only large VLC window.) VLC developer says that the player is not capable of doing it. Last edited by kolamorx; 24th July 2022 at 12:09. |

With respect, without providing detailed information about your source video, you are wasting everybody's time. Nobody can help you!
I have request this topic be closed.
