used chatgpt for some video editing today. what i wanted was for a list of fiels and videos to be overlaid such that 1.png goes onto 1.mkv, and so on, with adjustable transparency and duration for the overlaid image. it took maybe 5 minutes to get what i wanted which is very cool. im not a fan of windows batch script syntax so this is nice
>I have a list of video files, named 1.mkv, 2.mkv, etc.
>I also have a list of images, named 1.png, 2.png, etc.
>All the files are located in the same folder.
>I need a FFmpeg command that will overlay the image files onto the video files, with transparency.
>1.png will be overlaid onto 1.mkv, 2.png will be overlaid onto 2.mkv, and so on.
>I am using Windows 10 and the command and syntax should work for Windows 10.
>for %%a in (*.mkv) do ffmpeg -i "%%a" -i "%%~na.png" -filter_complex "overlay" -codec:a copy "output/%%a"
this works but the image just completely replaces the video. i ask for a duration for the overlay, as well as a transparency amount for the overlaid image
>for %%a in (*.mkv) do ffmpeg -i "%%a" -i "%%~na.png" -filter_complex "[1]format=rgba,colorchannelmixer=aa=0.5[trans];[0][trans]overlay=duration=5" -codec:a copy "output/%%a"
this seems like it should work but it seems windows doesn't have this duration option so i ask it for something else
>for %%a in (*.mkv) do ffmpeg -i "%%a" -i "%%~na.png" -filter_complex "[1]format=rgba,colorchannelmixer=aa=0.5[trans];[0][trans]overlay=enable='between(t,0,5)'[out]" -map "[out]" -codec:a copy "output/%%a"
this works, each video begins with the respective overlaid image, and the transparency/duration is adjustable. however the audio was discarded
>for %%a in (*.mkv) do ffmpeg -i "%%a" -i "%%~na.png" -filter_complex "[1]format=rgba,colorchannelmixer=aa=0.5[trans];[0][trans]overlay=enable='between(t,0,5)'[out]" -map "[out]" -map 0:a -codec:a copy "output/%%a"
this works perfectly

First time into programming, i'm learning Python.
I wonder if you can do cool stuff with it, (like web dev) or should I just drop it for another language.

i have the idea to feed a story into stablediffusion one word at a time, and use 50 of the previous output as img2img input so that it blends between the two images. and then time it all together with a tts recording of the story
for example
image 1: once upon a time there lived
image 2: upon a time there lived a
image 3: a time there lived a wizard
image 4: time there lived a wizard who
etc to the end of the story
i have not used stablediffuion by command line yet, always a gui. every time i tried to install commandline stable diffusion i miss some requirement and it doesnt install and it's a pain in ther ass. i am wondering if i can just hack something togther using the stablediffusion installed by these gui versions. basically using the gui to install and get sd working, and then bypassing the gui and calling their install directly with prompts
i would love to do the tts via suno-ai/bark but i cant get cuda/pytorch working so it uses cpu which takes forever, also there is no continuity between voice styles when i last tried it. but if those were fixed it would be great

i have a cymk jpeg. in image viewers such as nomacs and even firefox, it is very saturated and this saturated color image seems to be the 'correct' version, but i hate it. in windows 10 file explorer (thumbnails), and old image editors without color management features (paint.net), it appears with 'dull' colors which i find infinitely more appealing
i have tried stripping all the metadata, converting to srgb, removing icc profiles, but i can't obtain the 'dull' version that windows shows me, at least not via command line… i can simply open it with paint.net or clipstudio paint, and simply resave it as jpg and it will appear 'dull' everywhere, which is what i want, but i want to be able to do this in bulk and i have no idea how to do this. what kind of conversion is paint.net and clip studio paint performing to obtain the dull image? every fucking online service and commandline tool and shit makes it become saturated. fucking color bullshit
none of these convert it into the dull image correctly
exiftool -r -icc_profile= test.jpg
exiv2 rm test.jpg
magick test.jpg -colorspace sRGB -intent perceptual test2.jpg
magick test.jpg -strip test2.jpg
from PIL import Image
image = Image.open('test.jpg')
image = image.convert('RGB')
image.save('test2.jpg')
i'd post the image but it's porn so oh well
No.65569
>>65565that's not what i mean, it's just… there's a way windows and older image editors are converting from cmyk to rgb, and it results in a dull image, which is what i want. but i cannot for the life of me replicate this conversion, they all end up 'correctly' saturated. i thought there was an embedded icc color profile but i've stripped everything from this god damn image, it's purely a result of the format being cmyk and nothing else
i will probably just desaturate it until it matches or something, i don't know what else to do. it seems like such a hack but i can't figure out how to produce the dull variant via commandline, because all the other editors and stuff produce the exact same dull image, which means they aren't just arbitrarily desaturating, they are using some method. i thought it was just a result of ignoring the color profile but imagemagick doesn't seem capable of converting to the dull variant. i've tried all 5 profile intents as well
No.65574
>>65569I don't know any solutions, but I know what you're talking about. When I view raw image formats such as DNG and NEF in Windows' default image viewer, the thumbnail and LRF version is quite saturated and contrasty (REC.709 space??) but the full image upon loading converts to what looks like the D-LOG color space captured by cameras pre-processing.
Maybe just desaturate you entire screen with your GPU's control panel? Or through the monitor itself? NVIDIA cards may even be able to apply selective color settings on a per-application basis, which might work on windows 10+ as the newer "photos" program uses DirectX so your GPU might be able to alter its windows as it would a video game.
No.65596
>>65574i figured out the image is utilizing adobe prophoto rgb colorspace, but windows explorer is not color managed and interprets this as plain rgb or something and it is desturated. while incorrect, i strongly prefer the desaturated version that windows and other programs show, instead of the overly vibrant and saturated correct version that color managed photo viewing apps show me
still haven't been able to figure out how to convert from this color space, but i did figure out i can desaturate, lower blue channel, raise red channel, and then lower contrast to achieve something similar
if i change my gpu or display, it will affect everything, but only these images are bad. id rather just find a way to fix them before changing how everything displays

i want this incorrectly desaturated version because it paradoxically shows more detail, at least for my monitor. the saturated one has horrible color levels and looks like a mess

ffmpeg.exe -i video.mkv -ss 110 -crf 30 -preset veryfast -vf subtitles=video.mkv:si=0 video.mp4
i had to hard encode subs to make anime playable on my old phone, this is what i used
ss 110 skips the first 110 seconds, skipping the intros
crf 30 is really low quality but significantly reduces filesize
preset veryfast just speeds up encoding
-vf subtitles=video.mkv:si=0 is a filter to hard encode the subtitles from video.mkv, using the 1st(0) subtitle index (english) - you look at streams by via ffprobe
the problem i had was trying to map select the video, audio, subtitle streams while also hard encoding them with a filter, in one pass. i still dont know how to do this, but this seems to select the right audio and video streams without specifying it, leaving only the subtitle stream necessary to specfy, which lets you filter it since no mapping is done. it is simple but i spent an hour figuring it out. i really wish someone posted this to the stack overflow thing regarding converting mkv to mp4 and retaining subs
