If you need -80ms audio delay you have to set -80, not 80.
With the mp4 container the delay is written but not shown. This is a problem with the ffmpeg mp4 muxer.
Reload the muxed mp4 and see the video and audiostreams offset.

[lomero]

tried also -80 and the same. no delay on final mux mp4. and yes, maybe MediaInfo can't show delay, but delay not present on final mp4 file

How did you check that?
As a test mux to mkv and control with mediainfo.

[lomero]

mediainfo can't show delay. right and understand. anyway i've try mux audio+video (with audio delay -80) and play final mp4 can't have delay
tried also mkv as output and the same. i think need re-encode to have delay ... (also AI says this). but well if re-encode isn't necessary is better ! one work less

Ai is wrong, no need to reencode.
I'll check this, when I have some time, and come back to you with the result.

[lomero]

thanks. however already tried 80 and -80, final mp4 and also mkv. and all the same, no delay
with re-encode

ffmpeg -i video.ts -i audio.aac -filter_complex "[1:a]adelay=80|80[aud];[0:v][aud]concat=n=1:v=1:a=1" -c:v libx264 -c:a aac -strict experimental out.mp4

finally delay is present

What I meant is when the program is closed and opened again, it defaults to mkv, always.

Where (in what window) it defaults to mkv? What version do you use?

In the multiplex window. I am using the latest stable version. Thanks.

Good idea to show the stream delay on the source page and put it in the multiplex grid.


NEW smaller findings:

The "Chapters help" window does not close when the window "FFplay play controls" open.

The window "FFplay play controls" does not appear on the Various -> Crop page.

I think it would be good if the chapter preview included the information for I/P/B frames.

A space is missing between clickAdd at the Chapters page.

Trying the advice in https://forum.videohelp.com/threads/396490-clever-FFmpeg-GUI-small-FFmpeg-UI-fully-por...49#post2763689 got some confusing results, that I didn't catch in my first post.

After some fumble finger attempts, what I didn't realize at first was that the MKV file in the clever FFmpeg-GUI output folder must've have been some sort of intermediary step, as there were also files written to the input directory (MP4 files).

The MKV file in clever FFmpeg-GUI output folder looked OK on the PC, and also looked OK on the TV, but had no sound/audio.

Of the two MP4 files in the input folder, both had sound/audio, but the first looked "squashed" on both the PC and TV, while the second looked OK on PC, but squashed on TV, just like the original file.

Stating this another way, if the MKV file in the clever FFmpeg-GUI output folder had sound/audio, that would've been the desired result.

Would lines from MediaInfo be needed to explain what is going wrong?

[davidt1]

I tried to use the latest beta but without much success. Joining two mp4 files resulted in a dialog box saying, "Video analysis failed" and the program deleted the files. I would rather lose the subtitle in the previous version than losing the files.

I used a different program to cut two mp4 files for joining. This time clever ffmpeg says "task was successfully done" but there is no joined file.

I a going back to the stable release.

If you have followed my instructions in the post above, a new video stream has been written to your destination folder as an mkv file. Nothing will be written to your source folder (unless you deliberately choose to do so with the target/source button).
Only the video stream was changed during this process, the other streams remain untouched.
If you had clicked on multiplex after encoding, you would have had all streams available for muxing.

Now you have to proceed differently:
Load the newly created mkv file (the one with the black bars), click main page, click multiplex.
Drag the original mp4 file (the one with sound) into the window; select all streams on the left side except the video stream of the original file (you don't need it anymore), select mkv or mp4 as container and click multiplex.
Now you have your new video file with sound.

Of the two MP4 files in the input folder, both had sound/audio, but the first looked "squashed" on both the PC and TV, while the second looked OK on PC, but squashed on TV, just like the original file.

One of them is your original file, you should know which one. I have no idea where the other one comes from.

If the video analysis has failed, the video is defective. In this case, it is only deleted in the grid, the real files are not deleted.

I am not a fortune teller, I would need the mp4s to know the reason.

NEW smaller findings:
The "Chapters help" window does not close when the window "FFplay play controls" open.

It is not supposed to, it is covered by the ffplay controls help as long as ffplay is active and is available again afterwards.

The window "FFplay play controls" does not appear on the Various -> Crop page.

That makes no sense here either, the video preview here only serves to display the crop result.

I think it would be good if the chapter preview included the information for I/P/B frames.

What for? The preview in chapters is used to find the chapter times, you don't need this information for that.

A space is missing between clickAdd at the Chapters page.

Will be fixed.

Not true, with mkv it works fine (tested!), with mp4/mov not.
Will see, what can be done for mp4/mov.

for me mp4 container or mkv is the same. and i also did a test (before posting here) and for me the final mkv had no audio delay. with code on my post#1628 finally i have delay. but re-encoded needed. i will do more tests


edit: again another test just now. and i confirm, muxed on mkv delay still not present ... here clever shot

If you had clicked on multiplex after encoding, you would have had all streams available for muxing.

Doing your rescue steps made the output file that plays on the TV OK with sound/audio.

When starting from scatch, to do this all as one operation, I don't see a "multiplex after encoding" option.
That is where I went wrong originally.
I see that if I don't close the program, I can back out of Encode and into Multiplex, with the files already in the grid.
Is that what you mean?

(My original question on Page 49 was if or how to do this in one step, with the idea of doing a batch of them later, if possible.)

It's working now. All is good. Though the multiplex page still defaults to mkv when the program starts. I only use mp4. Wish I can make that the default container. Thanks for your hard work.

Good

These do not exist either.
As can be seen in the program description, it processes each stream individually.
This has the advantage that you can only edit the stream that you want to change. The other streams remain untouched.
After the desired changes, you can mux the streams back into the finished film.

I see that if I don't close the program, I can back out of Encode and into Multiplex, with the files already in the grid.

Exact.

My original question on Page 49 was if or how to do this in one step, with the idea of doing a batch of them later, if possible.

Not possible, encoding and muxing, 2 steps.

Yes, I noticed this because I moved the Chapter window (app), the "Chapter Help" window stays where it is, and then opened the preview so that the "Chapter Help" window is half hidden by the "FFplay Playback Controls" window.

BTW: You already fixed that for the Cut page.
When the "FFplay play controls" window open, the "How to use the cut function" window close. And when you close the Preview, the "FFplay play controls" window close and the "How to use the cut function" window reopen.

It's not tragic!

Depending on what you crop, different borders or partially displayed logos or tickers, you may have to navigate in the video.
And if you can't remember the keyboard shortcuts, you can take a look at this help page.

When you choose a new chapter, it's good to know that you're capturing the first image of a new scene, the I frame.

But it also works without it.

since final mkv with audio delay work for you but not for me try with my video, just 5 min. already set on mux audio delay -80, but as you can see audio is not sync with video. try yourself to add delay, without re-encoding

Insert -1450 as delay into the aac row and mux to mp4 or mkv.

wonderful work great. how did you get 1450 ?

[ingsoc]

batch operations with audio encoding for length and pitch, are failing. v3.3.8.01. Second and more batch tasks are not taking the correct encoding settings from first defined operation. In previous versions that was working perfect. The versions without the problem described in the next paragraph...

Also and by the way, the new way to show presets is not good at all since only show 2 or 3 presets from a big amount that are possible, and custom values and their fields to insert them are in the last position and require several clicks to appear .
May I suggest the inverse position?. Custom first and showing fields by default, just like was before when no presets are showed, because it is the most common operation there. Without clicks to insert custom values, just like before.

About other detail, with 4k resolutions the checkboxes in the grid controls are very very small. Surely some DPI adjust would be required to make them bigger...

This can only work if all videos have exactly the same duration, which I highly doubt.

Wrong, there are actually only a few options.
For everything else there is the custom option, now also with entry of the desired duration.

Audio, I was speaking about audio only. Not video. And the conversions worked in previous versions for all the audios. Why shouldn't ?

About 'custom'. So you only thinking in those 2 presets ? only those 2 you think that matters ? sorry, you wrong. There are many more, but specially for that reason important there is 'custom'. Placing custom in the last position the ide is giving more work that should for the most operations on that function. And also you haven't seen yet what happens with that new bad way when 'stay open' is used when 'custom' is used....
