How Do I ammend custom command in BT_open.txt in destination folder via batch open/close method in Clever FFmpeg GUI.I am somewhat cunfused after reading the content in BT_open.txt. Is there some other simpler method to put the command directly in the gui.

Manipulating the command line in BT_open.txt is something for experienced users and will result in error messages and crashes if used incorrectly.

The GUI is designed so that no command line can be entered, allowing every user to use ffmpeg in a simple manner.
If someone knows how to use the command line, they don't need a GUI.

OK go it but by giving the same parameters of ffmpeg - i command >>>

ffmpeg -hide_banner -y -i "input.mkv" -filter:v "fps=30" -map 0:v -map 0:a:m:language:eng -c:v libx265 -preset faster -crf 22 -pix_fmt yuv420p -threads 0 -c:a copy -sn -movflags +faststart "D:\UTDL\FFmpeg Output\output.H265.mp4"

in CFFmpeg GUI > Btopen.txt >>>

Video ---> x265 (hevc) - Stream ID 0 from?C:\FFmpeg\bin\F1.mkv?910432?-hide_banner -loglevel error -stats -y -fflags +genpts -i "C:\FFmpeg\bin\F1.mkv" -vf fps=30000/1000,format=yuv420p -map 0:0 -c:v:0 libx265 -preset faster -crf 22 -aspect 2.39 -an -sn -dn -metadata:g encoding_tool="clever FFmpeg-GUI" ?D:\UTDL\FFmpeg Output\F1_V0.mkv?1?

I get the ouput video with more brightness which unbalance the video but with ffmpeg -cli command it's perfect.

That doesn't make sense because the two command lines are identical except for the container.

[sam12345]

I have found it. It's to keep the original frame rate as source video i.e. 23.976 and not to change to 30.
Color space to BT.709 and color range to Limited and pixel format to yuv420p in the CFFmpeg Gui. Resulted video perfect.


I have to remove the -filter:v "fps=30" from FFmpeg -CLI too.

Kindly tell about the frame rate. My source video is 2.40.1 and the gui forces to 2.39 and does the gui uses all the threads for CPU encoding : -threads 0

Lastly, Does the gui Multiplex do [-movflags +faststart] for .mp4

If your cli commandline is ok for you, so there is no need to change the color space, nor the color range (already limited) in the gui.

Kindly tell about the frame rate. My source video is 2.40.1 and the gui forces to 2.39

You mean the aspect ratio, not the frame rate.
There are no films with AR 2.40, but with 2, 2.35, and 2.39.
Therefore, the correction is correct.

and does the gui uses all the threads for CPU encoding

Yes.

Lastly, Does the gui Multiplex do [-movflags +faststart] for .mp4

Yes, you'll find this option in the multiplex window.

can you embed this batch command for autogeneration of chapters in GIU.

@echo off
setlocal EnableDelayedExpansion

if "%~1"=="" (
echo Drag and drop a video file onto this script.
pause
exit /b
)

set "INPUT=%~1"
set "CHAPTERS=chapters.txt"

:: Get duration in seconds (may be float)
for /f "tokens=* delims=" %%A in ('ffprobe -v error -show_entries format^=duration -of default^=noprint_wrappers^=1:nokey^=1 "%INPUT%"') do (
set "DURATION=%%A"
)

:: Strip decimal part if present
for /f "tokens=1 delims=." %%A in ("!DURATION!") do set "DURATION=%%A"

> "%CHAPTERS%" echo ;FFMETADATA1

set /a COUNT=0
:loop

Automatically generated chapters at fixed intervals do not make sense.
Chapters should be there to separate scene changes and similar.
And these are different for every video.

ok. this one [Timebase]

EDIT

This batch Script works fully as per Scene Detection. Request you to embed the same in gui for automatic chapters generation.

This seems ok to me. Will implement it.

[sam12345]

MKV Toolnix has the option to Generate Chapters at regular intervals.

[Attachment 89240 - Click to enlarge]

Wondering if you can implement that to. It will be a great convenience for auto generation of chapters > even at regular intervals instead of adding them manually.

Auto generation of chapters at 10 minutes regular interval TXT of the batch (.bat) enclosed herewith

[sam12345]

New batch to add Custom_Chapters on regular intervals on Video Length Detection [More Refined].
This is what we are doing in CFFMpeg GUI

Enclosed TXT of the batch(.bat)

This auto generate the chapters on regular intervals based on separate video lenght

@ProWo

the batch for scene detection has worked for 30 min video. sample here

[ProWo]

the batch for scene detection has worked for 30 min video.

clever FFmpeg-GUI automatic scene changes detects one chapter more in this video.

Yes, it has made 7 chapters but not muxing the video in multiplex. Short videos are not multiplexing in multiplex with scene detection. Fixed intervals are working fine with short as well as large videos.

Then you did something wrong.
After creation, the new chapters are automatically loaded and activated (you can see this with the red “deactivate” button).
Click on “Return” to return to the multiplex window. In the top right corner, you will see “Chapters C” (which stands for created chapters).
Now select a compatible container (mkv, mp4, mov). If you select an incompatible one, an error will be displayed in the top right corner.
Then click on “Multiplex” and the created chapters will be muxed into the video.

I know the procedure but multiplex is not doing short videos in mp4/mkv.

It works as aspected here with me.
Could you upload this video and post the link here?
I have to test this with your video.

It's here Without chapters

Thx, tested with your video and found the bug.
It was reading pts instead of pts_time.
Fixed now, update.

[sam12345]

Tested, 3.4.6.13. OK; working.
