Share your FFmpeg buttons!

[KozakMak]

okay, I know some for example:

del audio:

Code: Select all

ffmpeg.exe -i %P%N -an -vcodec copy "%O_noaudio.%E"

extract audio: (how to extract correct .ext ?)

Code: Select all

ffmpeg.exe -i %P%N -map 0:a:0 -c:a copy -vn "%O_audio.%E"

make gif:

Code: Select all

ffmpeg.exe -i %P%N -vf "fps=15,scale=320:-1:flags=lanczos" "%O.gif"

cut:

Code: Select all

?ffmpeg.exe -i %P%N -ss 00:00:00 -to 00:00:05 -c:v copy -c:a copy "%O_cut.%E"

Share what else you know! For example, how to merge selected files?

Convert to H264 (original)

Code: Select all

ffmpeg -y -hwaccel dxva2 -threads 6 -i %P%S -c:v h264_qsv -c:a aac -b:a 128k -ac 2 -b:v 3500k -profile:v main -preset slower "%O"_H264.mp4

Convert to H265 (1280x720)

Code: Select all

ffmpeg -y -hwaccel dxva2 -threads 6 -i %P%S -c:v hevc_qsv -c:a aac -b:a 128k -ac 2 -b:v 3500k -vf scale=1280:720 "%O"_720pHEVC.mp4

Merge selected video

Code: Select all

%COMSPEC%
chcp 65001 && (for %%i in (%s) do @echo file '%%i') > listfile.txt && ffmpeg.exe -f concat -safe 0 -i listfile.txt -c copy "MergeOutput.mp4" && del listfile.txt

Merge selected video

doesn't work
okey, figured out - must be '%%~fi'

...but it doesn't work with Cyrillic in the paths.

Therefore you need the chcp command to change the codepage in order to support cyrillic letters.

I mainly use these three CMDs on a button to with parameter "%P%O.%E"

Convert audio to AC3:

Code: Select all

%~dp0ffmpeg.exe -i %1 -map 0 -vcodec copy -scodec copy -acodec ac3 -b:a 640k "%~dpn1-AC3.mkv"

Convert to 720p x264 and AC3:

Code: Select all

%~dp0ffmpeg.exe -i %1 -map 0 -vf scale=1280:-2 -c:v libx264 -pix_fmt yuv420p -crf 18 -preset slow -scodec copy -acodec ac3 -b:a 640k "%~dpn1-720p-AC3.mkv"

Convert with Nvidia NVENC:

Code: Select all

%~dp0ffmpeg.exe -hwaccel_output_format cuda -i %1 -map 0 -c:v h264_nvenc -pix_fmt yuv420p -preset fast -rc vbr -cq 25 -b:v 0K -scodec copy -acodec copy "%~d1%~p1%~n1-720p-nv.mkv"

NVENC was not very well documented and there might have been changes...


The "-map 0" parameter copies all subtitles and other streams.

The "-vf scale=1280:-2" keeps the correct aspect ratio when scaling to 720p.

Because FFmpeg concat merging protocol, can only read text files in UTF-8 encode format.
Using system cmd.exe run this bat can generate txt in utf-8 encode format.
However, when TC called the command line, CHCP 65001 is ok,but generate UTF-8 encode txt it failed.
My solution is to integrate TCC/LE in TC to run this bat, which can generate UTF-8 encode text correctly.

Can you give more details?

you can download TCC/LE from https://jpsoft.com/all-downloads/all-downloads.html and install it. (FREEWARE)
in TC bar , define TCC/LE exe path to use it.
