clever FFmpeg-GUI, small FFmpeg UI, fully portable, no installation.

[ProWo]

Forgive me if this is not the right place to ask this, but I am desperate. I use Clever FFmpeg-GUI to add a srt file to an mp4 file that has dvdsubs. This software works perfectly. I would like to be able to do this with ffmpeg by itself, but have been unable to do it. I really appreciate it if someone can share the steps/commands to this in ffmpeg. Thanks.

FFmpeg.exe -i "your_movie_with_full_path.mp4" -i "your_srtsubtitle_with_full_path.srt" -map 0:0 -map 0:1 -map 1:0 -c:v copy -c:a copy -c:s mov_text output.mp4

Here it is assumed that the video has a video and an audio track.
The colors refer to command parts that belong together.
The codec mov_text is necessary because the mp4 container cannot contain srt directly.
If the destination was e.g. mkv, you could use copy instead of mov_text.

Thank you, but it does not work the way I hope. The commands you provided adds the srt sub but removes dvdsubs and only keeps the first audio stream. I need to add the srt file while retaining all the streams (1 video stream, 3 audio streams, and 3 dvdsub streams) of the original file, just like I can with Clever FFmpeg-GUI. Thanks.

Then use

FFmpeg.exe -i "your_movie_with_full_path.mp4" -i "your_srtsubtitle_with_full_path.srt" -map 0 -map 1:0 -c copy -c:s:3 mov_text output.mp4

where
-map 0 uses all streams from input 1
-c copy uses the source codecs for all streams
-map 1:0 uses the first stream from input 2
-c: s:3 mov_text uses the mov_text codec for the fourth subtitle stream.
The input and stream counter starts with 0.

Then use

FFmpeg.exe -i "your_movie_with_full_path.mp4" -i "your_srtsubtitle_with_full_path.srt" -map 0 -map 1:0 -c copy -c:s:3 mov_text output.mp4

where
-map 0 uses all streams from input 1
-c copy uses the source codecs for all streams
-map 1:0 uses the first stream from input 2
-c: s:3 mov_text uses the mov_text codec for the fourth subtitle stream.
The input and stream counter starts with 0.

Works perfectly. Thank you so much. Now I try to convert from mkv to mp4 with re-encoding while keeping everything, but I can't make it work. Can you help again, please?

trying to convert from mkv to mp4 with re-encoding:

ffmpeg -i "input.mkv" -vcodec libx264 -map 0 -acodec copy -c:3 mov_text "output.mp4"

error message:
Automatic encoder selection failed Default encoder for format mp4 (codec none) is probably disabled

Hi ProWo,

Just a minor thing. Browsing for sourcefiles in your GUI, h265, eac3 (and other) files don't show up with the lower-right type-window set at its default "Video & Audio Files (*.asf;*.flv etc...)". I think not all supported filetypes are added here.


[Attachment 78844 - Click to enlarge]

Where setting the windows to "All Files (*.*)" does make the streams show, making them able to be selected.
Would you care to correct this? I'm running version 3.2.6.

You are missing the codec for the subtitle files.

Use:

ffmpeg -i "input.mkv" -map 0 -c:v libx264 -crf 18 -c:a copy -c:s copy  "output.mp4"

Thank you again, but this does not do what I need. The original video has an srt sub and dvdsubs. -c copy does not work for srt. I can use -c mov_text for the srt sub, but it won't work for the dvdsubs . I need to copy both the dvd the subs and srt sub to the new file.

The command line is different for every movie.
You have to learn yourself if you want to do it manually.
The most important thing is to understand how to handle the individual streams.
You should first familiarize yourself with
-map
and stream identifier
first.
Google for:
ffmpeg mapping
ffmpeg stream identifiers.

How do I use the tool to remux DVDs and Blu-Rays?

Also, made the 1000th post here. Yay!

Load your file, click main, click multiplex, make your choices, click multiplex. Done.

How about adding a stay-on-top function? Thanks.

As long as you work with it, it should stay on top.
Otherwise, simply click on the icon in the taskbar.

Source-browsing now working like a charm. Thanks for this fix

it still "disappears" from time to time once you leave it in the background - clicking on the icon doesn't bring it back.

I have noticed this behavior on Windows 11, it seams to be a problem with explorer.exe.
If you minimize the other front window, then reappears.
Restarting explorer.exe resolves the problem too.
Anyway, i'm working on this.

Try the newest beta (v3.2.6.02) and report here, if there is an improvement for the "vanishing" bug.

Got this error while converting MKV to MP4 with two webvtt subs.


[Attachment 79616 - Click to enlarge]

[davidt1]

Adding webvtt sub to MKV and muxed as MKV. Subtile is displayed on the left side of the screen and is not removable. It should be in the middle of the screen and movable. I can replicate this behavior with ffmpeg if I use -c copy. If I use -c srt or -c webvtt, the subtitle behaves correctly.

@davidt1
I did some tests and found that the webvtt codec is incompatible with the mp4 container.
I will therefore block the muxing of webvtt to mp4 in the next beta.
Muxing webvtt subtitles into the mkv container with clever FFmpeg-GUI works fine here. The subtitle is centered, just as it should be.
Please post one of your webvtt subtitles here so I can reproduce your problem.

using ffmpeg, I added a webvtt sub to a mp4 video. The -c mov_text codec works fine.

[ProWo]

With

-c mov_text

you're recoding the webvtt subtitle to mov_text, witch is compatible with the mp4 container.

Hi!
I tried recently to demultiplex an MP4 file and got a strange result - the length of the video was only two and a half minutes instead of the full length of the movie. The length of the audio file was correct. Strangely enough, I tried to do the same with another well-known tool, MKVToolNix, and the result was the same. I tried then avidemux and this time I got what I wanted. Something seems to be wrong with these tools. I wrote this because I would like to help make these applications better.

Could you upload this mp4 and post the link here, so i can investigate further?
