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

[ProWo]

Issue: 0-channel AAC Audio stream loads into clever, can multiplex with AVC video stream,
outputs 0 size mp4 file with no errors, warnings, or fail message.

Thx, will activate the zero size file check for the multiplex output too.

Audio encoding, Channels (change. split. join). Use periods instead of commas.

A point at this location makes no sense.

At the page itself you use "Extract streams", just like on the other pages. On the Main page button it is "Extract Strames" with a capital S.

Will be fixed.

Would it be useful to offer a feature that automatically fills in the empty “Title” field with the country name if the "Language" field contains a valid entry for audio and subtitle streams, as in the ISO 639-2 table?
On older devices and players, the abbreviations and country names may appear in the selection.

No, because this titles would also have to take the user's language into account and could not be in English only.

Change Request
-----------------

I am proposing a minor change that would have a big impact on usability.

Although the audio fade in / out feature is popular, the video fade in / out
is NOT, at least in my opinion.

So, why have it [already visible] on the main video encode screen?

Change #1
------------
How about making a small button rename change, and a screen flow
change to match.

Default the video encode screen to show the various screen already
open [crop, rotate, etc ..], rename 'close various' button to 'Fade',
clicking it will take you into the less popular video fade feature,
as shown in image #1.

The Fade screen view remains as is, as shown in image #2.

Change #2
------------
A while back I saw a post by a user asking if Clever had a Crop feature.
off course it wasn't easy to find Crop, as it is buried under main/video/various.

Most users look for those popular common tasks:
Mux, Join, Cut, and Crop, Clever's current menu has 3/4 ..

Change #2: How about adding a Crop menu button [visible if video stream exists],
This would make more sense if change #1 is implemented.

or:
Simply rename the box title from 'Encode/Convert' to 'Encode/Convert/Crop'

v3.4.7.03 feedback

Overwriting the global title has been fixed.

Thanks for the last changes at the Chapters and Mux page!
So far, everything with chapters is working as intended.

Sorry. I mean that you actually use periods instead of commas at Audio encoding, "Channels (change. split. join)"

The Multiplex Titel field allows Ctrl c, v, x. Could you also add Ctrl a?

Will be done.

Good Idea, will be done.

I need help with SVT AV1. Clever did a good job encoding with this codec.

Then I tried with ffmpeg alone. The output is a video with black bars on the side, which I don't want. I want the original aspect. Thanks.

The command:

ffmpeg -i "input.mkv" -c:v libsvtav1 -crf 30 ".mkv"

Outputfile:

I don't think those are black bars ..

One way to find out.
Load your output video back into clever, video encode, preview ..
do u see black bars??

I did what you said. No more black bars on both the new output file and the old output file, which is what the original video looks like. This so weird. I don't understand what's happening.

Still I need to do it correctly with ffmpeg. Is there a way to look at the command Clever uses? Please point me in the right direction. Thanks.

Audio Encode Screen feedback ..

Some of my movies are split in 2 parts, I am currently trying to merge the two parts
into one. For that to happen without time-consuming full re-encoding, I need the video
and audio tracks to match exactly between the 2 files.

I noticed that Clever does not recognize audio profiles, so these 2 different audio profiles

Format : AAC LC
Format/Info : Advanced Audio Codec Low Complexity
Commercial name : AAC

Format : AAC LC SBR
Format/Info : Advanced Audio Codec Low Complexity [with Spectral Band Replication]
Commercial name : HE-AAC

Look the same to Clever, but they are not. When an HE-AAC encoded file is loaded, it is recognized
only as AAC.

** HE-AAC (High-Efficiency AAC) is an advanced version of AAC that incorporates two key technologies:

1- Spectral Band Replication (SBR)
2- Parametric Stereo
* Different AAC profiles might require re-encoding

1- I am not sure if Clever supports HE-AAC? Does it?
2- Can the audio profile be losslessly changed if all other parameters
(channel no, Bit Rate, Sample Rate, ..) are identical?

Request: Is it possible to include audio profile info in the audio encoder screen?

Another tool, like Losslesscut, does check audio profiles, and points them
out as mismatches during merging (concatenation) as shown:

Another request is related to the the Sample Rate [Frequency]:
Can you please default the field to match the source frequency and not
change it, all the time, to 48k.

and a 3rd and final request:
Please consider adding 'All Streams' check box functionality similar to what
was implemented in the video encode section. This is really important and
saves an un-necessary step of re-muxing the video, and all other tracks,
back in.

As always, thank you very much for considering, implementing, and
responding to our feedback and reasonable requests.

Keep up the great work.

Clever is on its way to become one of the best GUIs ever created for
ffmpeg.

Still I need to do it correctly with ffmpeg [Your ffmpeg command does not have any scaling, and shouldn't be affecting your video with black lines]

[videoAI]

There are 3 ways to check ffmpeg commands generated by Clever:

1- Modify <cmd_l></cmd_l> in portable.config [advanced].
2- Click 'to batch', exit Clever, and check BT_open.txt in your target folder. [easy]
3- Click 'to batch', go back to main screen, click 'batch tasks', hover over the task
record in the action column, & see the command. [easiest]

The simplest way is #3.

Is there a way to look at the command Clever uses?
