bug in Crop as shown in attached image below ..
bug is reproduceable on clever nightly, and actual release, for this specific video file (click crop button),
bug does not occur on all mp4 files, just this one so far.

The crop boxes seem to populate meta data from my video file, look at 'Left'.

I tried to change the actual crop start value, got an instant crash ... just by pressing the back space.

This seems to be a separate bug, in addition to the one above.

@VideoAI
You start the crop at 5 seconds, but the video duration is shorter....
retry to start at 1 second.

[videoAI]

@ProWo

I didn't actually start the crop at 5 seconds .. that was the default pre-filled value.
Retrying start at 1 sec, resolved the issue.

Thank You.

The second issue / bug, if I try clearing the start input box by using the back
button on my keyboard, I get an instant crash.

Try it ..

Thank you .. and keep up the good work.

Some cosmetic / minor changes to consider for your next release:

- Join Screen; Please change "Cutted" to "Cut" [past tense of cut is cut] cutted-or-cut
- Cut Screen; Preview; Please assign mouse middle button to [Pause/Play]
- Cut Screen; Preview; Please assign mouse Scroll Wheel to [Preview Volume Control]

I promise not to get mad if you decide not to implement any of the above, but
I am sure will be glad if you decide to implement them.

Thank you and keep up the good work.

After Bug#6, I decided to check all input fields for blank input validation bugs.

I tested the Audio Encoding screen .. no issues

Then I checked the Video Encoding screen ..

Bug#7

if I clear the FPS field and toggle the keep duration check box, I get a crash

P.S. since most of the errors introducing crashes are of type "Index Out Of Range",
would it make since to check all the code that uses indexes for added validation.

It's "Cutted" atm (not "Cutter"); will change it to "Cut"

- Cut Screen; Preview; Please assign mouse middle button to [Pause/Play]
- Cut Screen; Preview; Please assign mouse Scroll Wheel to [Preview Volume Control]

FFplay is a simple player with poor controls.
Pause/Play is already occupied by the space bar, Volume control is not available.

Bug#7

This is obvious. If you toggle the keep duration check box, the duration is recalculated;
the FPS value is required for this. If this is missing, the calculation cannot be carried out.
I will find a solution.

EDIT: Fixed. Reupdate.

3.4.2.51 Feedback

Done: Change Multiplex page text to "Set / change".
Fixed: Chapter Video only works when the source file video stream has idx 0.
Add: Embedded chapters are saved when an audio stream is encoded into M4A/MKA container. Cool!

---

When you have processed streams (or Batch tasks) and start the app, you stay at the Select source file page and do not get forwarded to Multiplex/Batch any longer. That's okay. Therefore, the detection of processed streams or batch tasks should be indicated under the page Herding or somewhere else. Perhaps also on the main page. Maybe in color?
I'm not suree whether the list of the files in question should also appear, since it is a popup
Anyway. When you click Join then Return, you get this message:

New multiplex grid behaviour in conbination with Chapters Video:

1a. If idx 0 is an processed audio stream and the grid also contain a video stream, Chapter Video now plays pure audio. Cool!
1b. If idx 0 is an processed audio stream and you swap the source video stream to idx 0, audio ist played instead of video.
1c. Hiding the audio stream does not change that behaviour of 1b.

I might found the problem. Swap is not enough. After the click on Swap use None then All to reselect or refresh the new sorted streams and it's working.

I want to do this as unobtrusively as possible and with as little interaction as possible; if streams/batches are available, you will find them in the corresponding windows (mux, join, batch tasks).

Can {Pause/Play} not be triggered by keyboard and mouse??

-- Feature Request --

I have a folder containing 1200 mp4s. I wanted to scan them all for errors.
Since checking the files one by one in Clever was not an option, I downloaded another
tool to do the job. The tool is a GUI of an FFMPEG script.

The tool did the job but was slow and generated some false positives.

Since Clever already supports 'scan for errors' and batch processing; is it not possible to
combine both to scan many files? or to scan a folder [of files]?

A feature like that would be a big time saver.

[videoAI]

Confirmed.
Bug#7 fixed.

Thank you.

The update window of 3.4.2.53 default is set to Update to last nightly.
When you switch to Don't update and click OK, reopen Update and switch again to Don't update and click OK, the update window does not open any longer.

I wanted to check if the last selection is saved or if nightly is the default.
