How about displaying "Drag & drop files once" as log as "Scan for errors mode" get displayed?
So you know that this special mode will end after the first drop.

Or could scan for errors always use batch mode?
When you click Scan for errors on the Main page, the source file is automatically added to the grid without using HWA-decoding and all possible other batch tasks are automatically unchecked. So you can execute just the source file scan with the next click, as before.

What if you could switch between "Batch tasks" including replication of batch 0, and "Scan for errors" mode which opens the HWA-decoding option but without replication of batch 0.

Will try your GUI and will update you

Tried the GUI. It needs improvement for MP4. Must have -movflags use_metadata_tags and
-fflags +bitexact for MP4. My CMD command worked perfect in FFmpeg for bit perfect output. Any one on this forum can use it.


ffmpeg -i input.mp4 ^
-map 0 ^
-c copy ^
-movflags use_metadata_tags ^
-movflags +faststart ^
-bsf:a aac_adtstoasc ^
-avoid_negative_ts make_zero ^
-fflags +bitexact ^
output.mp4

It doesn't end after the first drop.

Yes, of course, if there's a scan for errors task and you swap it to position 0.

When you click Scan for errors on the Main page, the source file is automatically added to the grid without using HWA-decoding and all possible other batch tasks are automatically unchecked. So you can execute just the source file scan with the next click, as before.

Only if you click the To batch button; therefore, I will remove this button here.

This is already possible with the batch 0 replication.

v3.4.8 feedback, Scan for errors mode

>> How about displaying "Drag & drop files once" as log as "Scan for errors mode" get displayed?
> It doesn't end after the first drop.

You are right, if the grid is empty or as long as idx 0 is a scan for errors (sfe) task.
But if idx 0 is a normal batch tasks, sfe mode end after the first drop.
The same applies when you swap idx 0 from sfe to a normal task.

To display "Drag & drop files to replicare Batch 0" during sfe mode is not entirely correct, as you can still change the HWA-decoding before the drop. So better use "Drag & drop files".

EDIT:
When you click Batch scan on the sfe page and the grid is empty, "Drag & drop ..." is missing. It appears after the first drop.

EDIT 2:
I'm not sure if the new upper right corner is usefull.

I disagree because the action is replicated. The fact that you can also change the HWA is just a bonus. If you don't change it, batch0 will be fully replicated.

When you click Batch scan on the sfe page and the grid is empty, "Drag & drop ..." is missing.

I will add this info when the grid is empty.

I'm not sure if the new upper right corner is usefull.

Not really.

Could you use the darker green background color for processed streams here? To stick with the usual colors.

unfortunately, HARDSUB encoding fail to burn the translation correctly; it misspells one of the Arabic letters. It replaces one of the letters with a question mark.

If you use a text based subtitle, you must check that's encoded as unicode (UTF-8), not ASCII.

The All button is displayed on the empty Batch tasks page (scan for errors mode).
In this case, only the Add files button is displayed at the top of the empty grid on the Join and Mux page.
I'm not sure if the Add files button is useful for batch tasks.

Chapters:
At fixed intervals is not selectable for some files any longer. You see that both options moving one or two pixels up at the first click of At fixed intervals. The issue is starting with 3.4.7.06

How about addin Abort, so you can stop processing when the file scan takes ages?

Sometimes this info window appears at the end of using At scene changes:

Chapters:

I think it happens with videos having timestamps problems.
Could you try to use the fix timestamps (lossless changes) with one of this videos, and then retry the chapters creation at fixed intervals with the new file?

[Findu]

Does not help with three tested files.

EDIT: Try the cut part from the F1 sample from older posts.
F1_fixed_fps_23.976_cut#0.mkv

EDIT2: Three other files do not have an offset or audio delay. All files work with 3.4.7.05 and older.

Please upload this file and post the link to test.

[Findu]

I had an older mentioned issue. When you cut one part and say not to Add to the join list, the empty Join page opens.
This just happens. I repeat this three times.
But it seems that this only happens when you use the cut function for the first time in a new version of the app. After closing the app, I cannot reproduce this.

Sample files with no chapters. Any one can test them > https://limewire.com/d/Iq2m7#3VlOvGOWTJ

BTW if some one needs the chapters creation at fixed intervals (auto mode) here is the batch file again > https://limewire.com/d/1fCmW#S7PFaWQVHH

wondering if ProWo can bring it too in GUI. I requested him this 12 day's before also.

and yes I do see

v3.4.8 feedback

My comments about Clever false positives ..

User, from review]All previous versions prior to 3.48 no problems downloading & running the program.

This is not accurate, prior to v3.4.8, Clever had one false positive (VBA32) on Google's virus total site.
I pointed it out in one of my previous posts and even joked about it.

Suddenly Norton Ant-virus detects Threat Name Win32:MalawareX-gen[Cryp] Threat type Cryptic -
This threat is heavily disguised to hide its malicious intentions?

There are now 4 antivirus programs (Norton, Avast, AVG, VBA32) who claim malicious intent and 3 of them
specify one exact threat type by name [Win32:MalawareX-gen[Cryp]].

Although I still believe those are all false positives;

1- The increase in the number of detections, now 4 [one by Norton, 3 by virus total]
2- The identification of one type of threat Win32:MalawareX-gen[Cryp] by, at least, 3 major reputable
antivirus vendors [Norton, Avast, AVG]
3- And coming close to crossing the virus total threshold of 4. Most users start to have second thoughts
if the detection level reaches or exceeds 4/71

should warrant some questions like ..

1- Was there a major change in code that increased the detection level? encryption? System DLLs calls, etc.
2- Could there be a real infection that slipped detection on the Dev system? An actual virus?
3- Can anything be done to reduce the detections? code change, letters to virus total or antivirus vendors, etc.

clever FFmpeg-GUI, is 100% virus/malware free. Your AV is wrong, false alarm.

To simply brush this off as the fault of the user's AV program may not be very helpful.

Note: I might write a small post about false positives and their impact on the availability of free software later, stay tuned.

[videoAI]

I can confirm that these 'glitches' do happen indeed.

Possible causes:
- Variable initialization
- Reading an older config file

It seems that this only happens when you use the function for the first time in a new version of the app. After closing the app, I cannot reproduce this.

[videoAI]

This could be a font selection issue than a Unicode issue, simply because
the user is complaining of just 'one letter' being replaced by a '?'.

unfortunately, HARDSUB encoding fail to burn the translation correctly; it misspells one of the Arabic letters. It replaces one of the letters with a question mark.

If you use a text based subtitle, you must check that's encoded as unicode (UTF-8), not ASCII.

I do think the screen shots on the forum Clever main page can use an update to reflect the new UI.

But aren't you a bit curious why Norton, Avast, and AVG are flagging your app as malicious ?

The automatic chapters generation issues seams to be solved.

Wrong transfere to the empty Join page does not occur here.

But the "Drag & drop ..." text is still missing on the empty Batch tasks page (scan for errors mode).
