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

[ProWo]

When you run Clever, main page has 3 buttons [open, Join, Multiplex]. if you attempted to load a damaged file,
you get an error [This file cannot be analyzed], and 2 buttons disappear [Join, Multiplex]. when you press Ok,
[Join] re-appears but not [Multiplex].

Thx for the hint, fixed.

Hint .. currently the update window shows this during an update ..


[Attachment 87883 - Click to enlarge]

As you can see, it might be confusing a bit to see what it looks like two OK buttons instead of one.
kindly fix .. either lower the front form to cover the back one [as shown] .. or make both the same length.

The video bit rate has not yet been read in, as this information is missing for many videos.

Testing v.3.4.3.25

I multiplexed an mp4, in Clever, as follows:

Stream 0:0, Video, h264, 720 x 1280, 0.56, 25 fps, und
Stream 0:1, Video, h264, 720 x 1280, 0.56, 30 fps, und
Stream 0:2, Audio, aac, 2 Channels, 47 kb/s, und, -4960 ms
Stream 0:3, Audio, aac, 2 Channels, 48 kb/s, und, -4960 ms

When I try to preview the video streams in Video Encoding, I can switch video streams [by selecting stream index (0,1)],
but both play with the same audio stream [#2 only].

Is that the way it is supposed to work?

[videoAI]

Muxing several videos with the corresponding audio streams into one file is very borderline.
I don't think there are many videos like this.
Nevertheless, I have adjusted this and you can now select the audio streams for these videos.

The new audio drop down in preview, works flawlessly.

Clever Doesn't remember its last position on the desktop screen.

So I tried using an Auto Hotkey script to move 'Clever' main window to the upper left corner so I'll have
more space for my soft keyboard on screen.

I tested a script with LosslessCut and it worked flawlessly .. no issues.

Tried to use it on 'Clever', it opens & runs 'Clever' but fails to move it no matter what I try.
The problem is: 'Clever' uses a main windows with a variable title (contains ver #), and special characters [©],
so calling it by window title isn't an option, while LosslessCut for, example, used a simple title [LosslessCut].

I tried moving 'Clever' by calling it by title, id, pid, handle, .. without success ..

ahk_title clever FFmpeg-GUI v3.4.3.27 © by ProWo
ahk_class WindowsForms10.Window.8.app.0.13965fa_r6_ad1
ahk_exe clever FFmpeg GUI.exe
ahk_pid 3152
ahk_id 1115486

Here is the Auto Hotkey script:

; Define the path to the program you want to run
programPath := "C:\Portable\PortableApps\CleverFFmpegGUI\clever FFmpeg GUI.exe"

; Define the coordinates to move the window to
xPos := 0
yPos := 0

; Run the program
Run(programPath)

; Wait for the window to appear
WinWait("ahk_class WindowsForms10.Window.8.app.0.13965fa_r6_ad1")

; Get the PID of the running process
pid := WinGetPID("ahk_class WindowsForms10.Window.8.app.0.13965fa_r6_ad1")

; Move the window to the specified coordinates
WinMove(pid, xPos, yPos)

BTW, here is the much simpler LosslessCut script, and it works:

Run("C:\Portable\PortableApps\LosslessCut\LosslessCut.exe")
WinWaitActive ("LosslessCut")
WinMove (0,0)

Feature Request:
==========
Now, wouldn't be much easier if you added the functionality, to remember the last position on the desktop, to 'Clever'.
Kindly consider it ..

Thanks .. and as always .. keep up the good work.

Not correct. The last position is saved and recalled at start.
Only if the window is moved completely or partially out of the screen coordinates, will it start in the center of the screen the next time.

3.4.3.27 Feedback

Multiplex grid behavior:

1. If the app is closed and I drop a file onto the app icon and there are still other streams to be processed, the multiplex grid loads the streams to be processed and also the file's streams. This is good.

2. If the dropped file is also the source (input.mkv) of the retained processed streams, all source streams are preselected in the grid, just like the processed streams. Is that intentional?

[Attachment 87906 - Click to enlarge]

3. This is also the case with suffixes to the file name (like input_e_att_chap_60.mp4).

[Attachment 87907 - Click to enlarge]

4. But if the dropped file is not the source of the retained processed streams, only the processed streams are preselected.

[Attachment 87908 - Click to enlarge]

5. If only one processed stream is selected, Simple Remux is displayed, which is correct.

[Attachment 87909 - Click to enlarge]

When you also select a source stream, Simple remux disappears, which is correct too.

[Attachment 87910 - Click to enlarge]

If you deselect the processed stream, Simple Remux does not reappear.

I spoke too soon. It remembers the right side of the screen, but not the left side.

The previous version remembers all positions.

There are so much to like about this app.

1. ProWo is quick to update and respond to the users.

2. That "check/uncheck" button on the multiplex page is very useful. Sometimes a video has like 6 audio streams and 8 subtitle streams, but I only need one of each. Being able to quickly uncheck all the streams makes the job faster.

3. But I don't need the streams I uncheck. Those should be deleted. Instead they show up on the next file/job and I have to hide them.

Keep up the good work.

[videoAI]

Try LosslessCut .. it works flawlessly in this area ..

I have been using losslesscut. It works fine for MKV and MP4, but not great for TP/TS videos. For TP/TS videos I still use VideoRedo, which is about 8 year old now and still the best.

How about an additional option to "clear the Multiplex grid after muxing"?

[Attachment 87918 - Click to enlarge]

If several files contain many streams and you want to keep only some of them while muxing, you could use "Return & Multiplex" or "Show hidden & Hide streams" to clear the grid of the remaining streams before you drop the next file for muxing.
With the new additional option activated, the grid get cleared after Multiplexing and Simple remux.
I'm not sure if hidden streams should be cleared as well.

[videoAI]

I think a simple 'Remove Selected' option is a better idea.
There is no reason to tie the removal to 'After Muxing'.
Remove when you want .. any time. keep it simple.

My preference is for 'Remove Selected' which satisfies all scenarios.

Ex: if you implement 'remove all', you can't 'remove selected',
but if you implement 'remove selected' you can 'remove all' by 'selecting all' first, then 'remove selected'.

How about an additional option to "clear the Multiplex grid after muxing"?

[ProWo]

Well .. I have some news for you .. the implemented feature does not work at all, It always starts in the center of the screen.

Do you use a screen scaling of over 100%?

[videoAI]

Golden Design Rules .. from my old days in programing:

- Build it for your users .. not yourself
- if you can open it, you should be able to close it. ['Clever' doesn't conform]
- if you can add it, you should be able to remove it. ['Clever' doesn't conform]
- if you can select it, you should be able to de-select it.
- and so on .. just common sense rules.

[videoAI]

No scaling .. 100%
My laptop is connected to my TV via HDMI. my TV [screen 2] is my Primary display.
my laptop [screen 1] is off [blank] when my TV is on, and comes on when my TV is off. [either or].

Well .. I have some news for you .. the implemented feature does not work at all, It always starts in the center of the screen.

2. If the dropped file is also the source (input.mkv) of the retained processed streams, all source streams are preselected in the grid, just like the processed streams. Is that intentional?

3. This is also the case with suffixes to the file name (like input_e_att_chap_60.mp4).

4. But if the dropped file is not the source of the retained processed streams, only the processed streams are preselected.

Changed.
The current behavior is such that the file names are compared with the file name of the first selected stream up to the first _ (underscore); if they are the same, the stream is selected, otherwise it is not.
The output file name is taken from the first selected stream.

5. If only one processed stream is selected, Simple Remux is displayed, which is correct.
When you also select a source stream, Simple remux disappears, which is correct too.
If you deselect the processed stream, Simple Remux does not reappear.

Should be fixed now.
