^so about that HE-AAC VBR i guess that license is not allowing this ?

about the m4a container, was about the new feature 'remember last used codec'. I tried to encode audio to AAC, and selected m4a container. Then, when i returned to the encoder, and tried to use 'wav', i obtained that warning. The warning itself is correct, but the problem was, all the buttons to return or exit encoder were hidding. Only way i had to fix that was closing the whole program.

About the using of external encoders, the idea is just to have a way to use 'whatever is required' to complete the task. For example, i focus a lot in HE-AAC VBR for obvious reasons of efficiency.

Newest beta (v3.2.5.01), online now.

Added: (Hidden batch function): multiple audio files can be added now (thx to ingsoc for the hint).

Fixed: Buttons bug with pcm in m4a (thx to ingsoc for the hint).

Improved: Cut help.

Changed: Small changes on cut screen, cut code.

@ ingsoc

Also i wanted to batch that operation with 2 audio input files, and the batch grid feature showed + mouse icon but it didn't allow me to add more input audio for the operation, only one.

Also other bug i have seen is when having export container for m4a, and having pcm as format to encode, obviously the program warned about, but the buttons were all hidding and there is no way to proceed from that point, other than to close the program and start again.

This two problems should be fixed now in the newest beta (3.2.5.01).
Try it and report here.

^testing just now batch feature for audio encoder with 3 input files. Also by the way changing framerate from them. Result was correct for 3 files. First created file is saying as filename 'Title1_0_0__23.976_L&P', but second and third file are not showing the framerate change on their filename. 'Title2' and 'Title3'. I think that you want to rename all created files... ?
But yes, the most impresive feature is working like charm

Hi!

Exist anyway to add a new option to set "constant bitrate" in video encoding for x265/x264 ?

Set CFR can be a difficult to determinate the size of the output file

I don't want to compromise on quality and therefore rely on CRF. Unfortunately, a constant bitrate delivers poorer quality, so I'm not going to change that.
clever FFmpeg-GUI shows you the average bitrate.
Encode 2-3 minutes and you have approximately the average for the whole movie.
If the bitrate is too high, increase the CRF value, otherwise vice versa.

Thank you for making this useful app. Requesting features: open file with Clever FFmpeg Gui with right click; accept vtt subtitles.

[ProWo]

Newest beta (v3.2.5.02), online now.

Added: Warning with pcm_bluray encoding with 8ch (not working).

Fixed: Bug in pcm encoding to wav (file >4GB), bug in trueHD encoding (thx to Hellboy. for both hints, thx to tebasuna51 for the pcm switch).

That would mean a lot of work and brings no real advantage.

Newest beta (v3.2.5.03), online now.
Added: Sample muxing (request by kssxs).
Fixed: Bug in audiofilter with flac encoding.
Removed: -rf64 auto filter with pcm encoding, not working as aspected.

Hi ProWo,
I notice a possible wrong fps detection with m2ts/VC1 coded Video with the 3.2.5.03 beta.
It shows 47,952 fps even though it is 23,976 fps (with tsMuxeR/Media Info/MPC-HC/VLC).
m2ts/H264 coded Video is shown correct. Older 3.x Versions have not this problem.



Thanks for your "Swiss Army Knife".
greetings from Amiga

[ProWo]

@Amiga
Could you upload a small chunk of this file here, for analysis?

EDIT:
I have analyzed the samples and confirm the bug.
It will be fixed in the next beta.

[ingsoc]

ProWo a possible interesting feature to add to the audio encoder would be the one that allow us to insert X seconds of silent audio to the beginning. And i wonder if FFmpeg has something to blank x seconds of audio at the beginning or at certain time position...

I think both features would be interesting specially when we need to cut parts where the classid fade out still has sound and the keyframe was before...

And for sure a featue request that for sure you had in mind since the batch feature: multi-threating.

This feature would only help very few people, as in 99.9% of cases the audio track is the same length as the video track.
Track shifts are possible with the delay function, as is muting at the beginning and end with the fade function.

And for sure a featue request that for sure you had in mind since the batch feature: multi-threating.

If you are using the latest (2024) ffmpeg releases, multithreading is already integrated and will be applied automatically.

Newest beta (v3.2.5.04), online now.
Fixed: Bug with using raw vc1 streams, bug with framerate recognition of vc1 in m2ts (thx to Amiga for the hint).
Improved: Video indexing for cut, keyframe cut precision.

[Amiga]

Hello ProWo,

Since I am a simple user, there are always things that I possibly misunderstood.

e.g. in previous versions, after a volume scan, the determined values were displayed. Currently, I am immediately taken to the other settings.
So I no longer see the scan result. It is also not used by the program.

e.g. the "Spectogram" option scans the audio stream. I would now expect a graphic or a file so that I can view the spectogram.
I am missing both. No graphic on the screen, no file anywhere on the hard disk. Errors do not occur in any case.

I would be pleased if you could explain this to me. Error or misunderstanding?

Thank you very much
Amiga

PS: Used 32 bit FFmpeg version 6.1.1 from February 2024 (from GitHub)

About multi-threating, the batch feature work only in one list entry at time. So, what you meant exactly ?

[ProWo]

That is not correct. After the volume analysis, the audio encoding window is opened directly and the value determined is displayed in db and also used if it is greater than 0. You can also change this value clicking on audio filter.

e.g. the "Spectogram" option scans the audio stream. I would now expect a graphic or a file so that I can view the spectogram.
I am missing both. No graphic on the screen, no file anywhere on the hard disk.

After the analysis, a png file with the name of the video/audio file is created in the destination folder and automatically opened with the viewer that is linked to png.
If this image is not opened automatically, you are missing the link from png to an image viewer.
Right-click on a png file, open with, select another app, select your image viewer, click always.

You have to pay attention to the used threads of ffmpeg.exe, not those of clever FFmpeg-GUI.

maybe i didn't explain it well. See this picture, it is the worker from megui processing 3 jobs at same time.



The implementation of this feature will make the batch feature in clever FFmpeg-gui so powerful and well, we have cpu cores and their threads to take advantage of time, precissely what your tool is doing possible with such amazing features.

This has no advantage.
If the first job uses 100% cpu, then e.g. 3 simultaneous jobs use 3x33% cpu.
The total time requirement remains the same.

[Amiga]

Dear ProWo,

Thank you very much for your clear explanations. The volume detection does indeed work, unless the value is 0.0 db.

I find the current detection somewhat misleading because a db value is added too seldom in my case. (Out of 8 files it was only one).

You just don't know nothing, because nothing was taken over. In earlier versions you always knew the actual result.

The spectogram never works for me. I have the suspicion that it either only works under 64 bit and only with the original FFmpeg builds.
All 32 bit builds I have tested cannot output spectograms.

In the meantime there is an ffmpeg 7.0 - 32 Bit build from 2024-04-19 on GitHub. It does not work with it either.

Thanks again for your effort.

Kind regards
Amiga

The actual result has not changed.
If nothing is displayed, the result is 0 and the volume is not changed. Very clear and unambiguous, also 1 click less.

The spectrogram should of course also work with 32 bit systems, unfortunately I cannot test this.
Download the enclosed png file (right click, save graphic as) and double click on it.
Does it open and display?
If not, change the file association for png as follows (in the example for windows 7):

If this is successful and the png file opens automatically when double-clicked, then try again with clever FFmpeg GUI.

^Of course i meant that, when it is possible, example the audio encoder, same as was doing megui on that capture. For video encoder, probably not. See the fact that sometimes i push megui to audio encoder 8 tasks at time. All depends on the cpu and its cores/threads. The user must know about its cpu, and when proceed the multi-threating and when not.


Also, using 'crop detect' feature result in a video without audio or subs streams. Is this a bug ?

[ProWo]

This is not a bug, cropping only affects the video, all other streams are not involved.

a possible setting to exit result with other streams will be good, some checkbox or some... ?

...Very clear and unambiguous, also 1 click less.

All good. No problem with that. Some people need more time to get used to new things...

...The spectrogram should of course also work with 32 bit systems, unfortunately I cannot test this.

I can open a PNG file without any problems. But if none is created there is nothing to open. I can also live without the Spectogram.
I'm just curious to find out why it's not being generated.

Is there a switch in the ffmpeg configuration that should be activated? (e.g. --enable-, --pkg-config=, --extra-cflags= etc.)
If so, which one is it exactly? Then I could check whether this switch is present on 32 bit builds.

Sorry for the question, I'm pretty clueless. But to look the ffmpeg commands, that's still just about possible...

Thanks for your effort
Amiga


EDIT:
Spectrogram with Files near 1 GB or above are not working with 32 Bit, because "Out of memory" error.
~100 MB Stereo Files working perfect. Clever FFmpeg-GUI do not show that error, ffmpeg show it.

[ingsoc]

^ spectrogram is very important to know the audio quality. Thanx to it, one discover how the ppl, and even the platforms, create commonly very very bad audio...

[ProWo]

[davidt1]

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.
