need to convert a single image .jpg file to two files

[marcorocchini]

HI

I'm a cat

please have patience



SO, I wonder:

in a folder I have some files of photos (some .jpg mostly) I need to build a batch procedure so:

-->for any single source photo file I get another of them but saved in .TGA 32 bit with alpha channel
-->for any single source photo file I get the same image most blurred (c.d. fuzzy effects?) as background to apply the moving movement on key of the correspondant file

thanks

[pandy]

I don't get entirely what is your goal but as i pointed earlier (different thread) - for image processing i would rather use image editor (GIMP?), for image batch processing i prefer ImageMagick, ffmpeg can be used also for such processing.

First see how it works from the program level (batch processing). Then you write a script like here on the forum.

[pandy]

all images in folder will be converted accordingly to your information, ffmpeg and input images (jpg in my script, add extensions at will) should be in the same folder, result files are stored in new folders BACK and TGA

@setlocal

@set FFMPG=%CD%
@set PATH=%FFMPG%;%PATH%

@set OUTDIR1="TGA"
@if not exist %OUTDIR1% (mkdir %OUTDIR1%)
@set OUTDIR2="BACK"
@if not exist %OUTDIR2% (mkdir %OUTDIR2%)

@set /A nfile=0

@FOR %%a IN (*.jpg) DO (@echo converting "%%~nxa"

@ffmpeg.exe -sn -an -hide_banner -v 16 -stats -y -i "%%a" -filter_complex [0:v]split=2[IN_TGA][IN_BACK];[IN_TGA]zscale=w=-2:h=1080:f=spline36:r=full:d=ordered[OUT_TGA];[IN_BACK]zscale=w=480:h=270:f=spline36:r=1:d=0,avgblur=19,zscale=w=1920:h=1080:f=1:r=1:d=1[OUT_BACK] -map [OUT_TGA] -pix_fmt bgra -frames:v 1 -f image2 -update 1 -c:v targa -rle 0 "%OUTDIR1%\%%~na.tga" -map [OUT_BACK] -frames:v 1 -f image2 -update 1 -c:v mjpeg -q:v 1 -huffman 1 -intra_matrix 8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8 "%OUTDIR2%\%%~na.jpg"

@set /A nfile+=1)

@echo .

@echo Done! Converted %nfile% file(s)

oh my! it seems a super beautiful processing

--- Video ---
Size 1920 X 1080
No fielding
24 bit RGB-888-s from .JPG

thanks, it's perfect this

pandy for kindness is there a way to reduce a little the video levels for the background image?

pandy for kindness is there a way to reduce a little the video levels for the background image?

You mean less brighten. dimmed video ?

Try:

@ffmpeg.exe -sn -an -hide_banner -v 16 -stats -y -i "%%a" -filter_complex [0:v]split=2[IN_TGA][IN_BACK];[IN_TGA]zscale=w=-2:h=1080:f=spline36:r=full:d=ordered[OUT_TGA];[IN_BACK]zscale=w=480:h=270:f=spline36:r=1:d=0,eq=brightness=-0.1,avgblur=19,zscale=w=1920:h=1080:f=1:r=1:d=1[OUT_BACK] -map [OUT_TGA] -pix_fmt bgra -frames:v 1 -f image2 -update 1 -c:v targa -rle 0 "%OUTDIR1%\%%~na.tga" -map [OUT_BACK] -frames:v 1 -f image2 -update 1 -c:v mjpeg -q:v 1 -huffman 1 -intra_matrix 8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8 "%OUTDIR2%\%%~na.jpg"

yes I mean dimmed to low, but maybe I cannot see the differences in the code

And another thing: is there a way to don't change the resolution of output TGA image? I mean if the TGA can keep the same resolution of input file

and: if I try to use a image source that have height=1080 maybe ffmpeg return an error, could be?

for example this 2 attached jpg of same image:

https://www.swisstransfer.com/d/f2545c44-da65-4553-ac9b-56b774d25067

catlearn1.jpg is processed OK
catlearn2.jpg is not processed: because it have Height=1080

it' possible to process at any resolutions?
thanks

Difference in code is highlighted (bold black and red) - check for "eq=brightness=-0.1" move slider in command line window.

And another thing: is there a way to don't change the resolution of output TGA image? I mean if the TGA can keep the same resolution of input file

Yes, replace "[IN_TGA]zscale=w=-2:h=1080:f=spline36:r=full:d=ordered[OUT_TGA]" to "[IN_TGA]null[OUT_TGA]" - it should work.

Conditional ffmpeg is probably not possible from simple script like this - perhaps some shell / bash it could be possible or external apps but i can't help you on this - my "coding" skills are way to low.

[marcorocchini]

so, is there a way to d2 2 single processing: 1 for JPG background
and 1 for TGA ?


THANKS!!!!!

[pandy]

Please explain this in more detailed way.

[marcorocchini]

is possible: 1 commandline ffmpeg to generate .jpg background

and 1 separate commandline to generate the TGA

So if i understand correctly you wish to perform ffmpeg conversion twice.
Yes, check bellow:

@ffmpeg.exe -sn -an -hide_banner -v 32 -stats -y -i "%%a" -vf zscale=w=480:h=270:f=spline36:r=1:d=0,avgblur=19,zscale=w=1920:h=1080:f=1:r=1:d=1 -frames:v 1 -f image2 -update 1 -c:v mjpeg -q:v 1 -huffman 1 -intra_matrix 8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8,8 "%OUTDIR2%\%%~na.jpg"

@ffmpeg.exe -sn -an -hide_banner -v 32 -stats -y -i "%%a" -vf zscale=w=-2:h=1080:f=spline36:r=full:d=ordered -pix_fmt bgra -frames:v 1 -f image2 -update 1 -c:v targa -rle 0 "%OUTDIR1%\%%~na.tga"

[marcorocchini]

oh wow thanks



Pandy for kindness - it's to do some proof - is there a way to specify in the commandline "do a interlaced processing" to ffmpeg? or do an output so that is suitable to a interlaced processing?

ffmpeg is not easy to control from batch even if there is some possibility to modify on the fly how ffmpeg works.
To process interlaced video you need to add required filters (like deinterlacing - there is few of them available in ffmpeg).
So interlaced processing is possible similarly to Avisynth (in fact ffmpeg may accept Avisynth scripts as source if compiled with Avisynth support).

pandy for kindness: I need to zoom into the background image.

Consider that in any case it is blurry on output so even if it is cropped in its overall proportions, it is not a problem. Is it possible to make this change on the ffmpeg line?

Zoom? Dynamic or static?

[marcorocchini]

maybe, considering that is for a static image source, and the target is a static image .jpg I think a static zom
