clever FFmpeg-GUI, small single file FFmpeg UI, portable, no installation.

The video quality of this file is the best I can find on the internet. I just wanted to change the soundtrack to English.

This mp4 was muxed incorrectly.
That is why it is completely asynchronous.
The file cannot even be demuxed correctly by the creator program Mp4creator.
With the help of My Mp4Box-GUI I was able to demux it and mux the result again.
The correctly muxed file is synchronized and the streams are extracted correctly by clever FFmpeg-GUI and MKVToolnix.
So both programs are working correctly, the problem was with the source file.

[apkemu]

In such cases, there are always problems with the source file, which is what makes the solutions to resolve them highly valuable.

I told you the result from my analysis.
Try yourself to demux this mp4 with mp4creator (it was muxed with them).
The videostream will be extracted, the audiostream not.

[apkemu]

I did that already with Avidemux. I never valued that program much, but when it extracted the videostream and the audiostream correctly in an instant, the value of this program changed for me.
Somehow the creators of Avidemux managed to resolve possible problems with poorly formed files. Kudos to them!

I tried to extract the audio track and strangely enough the original file was renamed as - - - - -_ - - - - -.mp4 and also the audio track - - - - -_ - - - - -_1_aac.und.aac. I believe that the source file should always be left untouched.

[ProWo]

The original file is only renamed if its name contains non conform characters with Windows OS.
The target file is named as the source, adding a numeration, the language tag and the codec.

Newest beta (v3.2.6.03), online now.

Added:
UTF-8 support for filenames.

Fixed:
Bug in video stream extraction, with videostream index >0.

Changed:
Removed webvtt muxing to 3gp,flv,mov,mp4, not working.
Removed filename check and replace for non ascii characters, problematic with many foreign language filenames.

I've added UTF-8 support for filenames and removed the old filename check/replace.
Download the newest beta (v3.2.6.03). Should work now as aspected.

Newest beta (v3.2.6.03), online now.

is it possible to add "paste" function to the Browse For Folder dialogue (to quickly locate the needed folder)? i remember seeing a custom version of this dialogue with a path field that allows just that.

I don't know where to download the latest version.

I have to say, I'm a big fan of this little tool. Converting audio streams between FPS and other formats has never been that easy for me.

Now I came across the use case to convert a video file from 25 fps to 23.976 while keeping the total amount of frames and the audio in sync.

My idea was to convert the video stream to .h264 bitstream, change the fps, then use clever FFmpeg-GUI to adjust the audio streams and mux everything together.

As I have several files with several audio streams, this becomes quite a manual task.

Now my questions:
1) Is there any way to do this out of the box with clever FFmpeg-GUI with more or less 1-click?

2) Otherwise, which FFmpeg command is used by your tool to convert a 25 fps ac3 to a 23.976 fps file along with pitch adjustment?

There is a hidden feature in clever FFmpeg-GUI that copies a command line as a batch to any number of files.
The prerequisite is that all streams have the same ID, i.e. if you re-encode a video stream with ID 0 and execute it as a batch, then the stream with ID 0 will be processed with the same command line as batch 0 in all files added to the batch.
Adding MUST be done in one go, i.e. select the relevant files and add them to batch 0 using drag & drop.
The files cannot be added individually at the moment.

This way you can first re-encode all video streams in one go, then repeat the operation for all audio streams in one go.

The muxing afterwards must be done individually for each file, but all streams for this are then already available in the muxing grid.

Another note: If you select length and pitch when changing the first audio stream, all added audio streams must have the same frequency (e.g. 48kHz) as the first audio stream. However, if you only select the length, this is not necessary.

Encoding videostream from 25 FPS to 23.976 FPS with changing length, as batch:

@ProWo: I might have missed it, but is it possible to convert AAC 7.1 to TrueHD 7.1? When I tried, I got TrueHD 5.1 instead.

[Darkhorse]

@ProWo: my apologies if I missed it, but is it possible to convert AAC 7.1 to TrueHD 7.1? When I tried earlier today, the file was TrueHD 5.1.
Version I'm using is 3.2.6

Tested.
FFmpeg reports:

Specified channel layout '7.1' is not supported by the truehd encoder

so FFmpeg's truehd encoder supports only up to 6 channels.
Will remove the 7.1ch choice for truehd encoding in the next beta.

[Darkhorse]

Good to know. Thanks ProWo.
