Using vs filter for ass subtitles.

[Abdulaziz Alnasi]

Hello.

VS filter can handle ass subs better on "Arabic langauge" because it is RTL (Right to Left) language.
I find this app very amazing, but I was using hand creafted scripts and having troubles all the way.

but this ffmpeg-batch really amazing, the menu is attractive and easy to use, and there is burn subtitle option, if the burn uses vsfilter instead of libass, that would make it unbeatable.

Hi, vsfilter for batch subtitles will be added on next release.
Cheers

Amazing, I cannot wait to get my hands on it.

I'm afraid this is not an easy task. Could you provide a command line example to use vsfilter with ffmpeg? Does it require a custom ffmpeg.exe compilation?

FFmpeg itself does not support it, but you can easily just create an external .avs file to handle it, the .avs file uses Avisynth

I need to let you know that vsfliter works on windows, and since ffmpeg-batch mainly focuses on windows I thought that it won't be a problem to add a feature for windows users.
I don't know if vsfilter works on linux with WIne.

Avisynth can be found here:

If you want to see an app that generates avs file in action, try this one:

This tool supports both libass and avs, but it only supports 1 file a time, and does not have the flexibility that ffmpeg-batch has. so I really want ffmpeg-batch to support vsfliter.

Let me explain it in steps:

1 - create avs file for each video, you can use the template in "Fansub Encoder 0.3.5" then just fill the values.
2 - add that avs file instead of the video in ffmpeg, so Avisynth (avs) will do burn subtitle part.
3 - You might notice that avs file in "Fansub Encoder 0.3.5" generated avs file has this line:

AudioDub(FFVideoSource(X), FFAudioSource(X))

This line means the avs will load both audio in video, but if you want to load audio separately then you should use:

FFmpegSource2(X)

This will only load video via avs with not audio, and you can load audio separately to manipulate it depending on user preferences in ffmpeg-batch.

Do not worry, it is not difficult, just have a look at "Fansub Encoder 0.3.5" and you will understand it easily.

If you have any questions please let me know and I will be pleased to answer you.

Thank you for the thorough explanation about your request. Unfortunately such feature exceeds this application scope, as well as my decreasing availability for application maintenance. Apologize for previous expectations but for the moment I can't fulfill such request involving external applications apart from ffmpeg.
Good luck and best wishes
