Convert image sequence to video using ffmpeg and list of files
13 mai 2015, par rensaI have a camera taking time-lapse shots every 2–3 seconds, and I keep a rolling record of a few days’ worth. Because that’s a lot of files, I keep them in subdirectories by day and hour :
images/
2015-05-02/
00/
2015-05-02-0000-02
2015-05-02-0000-05
2015-05-02-0000-07
01/
(etc.)
2015-05-03/I’m writing a script to automatically upload a timelapse of the sunrise to YouTube each day. I can get the sunrise time from the web in advance, then go back after the sunrise and get a list of the files that were taken in that period using
find
:touch -d "$SUNRISE_START" sunrise-start.txt
touch -d "$SUNRISE_END" sunrise-end.txt
find images/"$TODAY" -type f -anewer sunrise-start.txt ! -anewer sunrise-end.txtNow I want to convert those files to a video with
ffmpeg
. Ideally I’d like to do this without making a copy of all the files (because we’re talking 3.5 GB per hour of images), and I’d prefer not to rename them to something likeimage000n.jpg
because other users may want to access the images. Copying the images is my fallback.But I’m getting stuck sending the results of
find
toffmpeg
. I understand that ffmpeg can expand wildcards internally, but I’m not sure that this is going to work where the files aren’t all in one directory. I also see a few people usingfind
’s--exec
option withffmpeg
to do batch conversions, but I’m not sure if this is going to work with image sequence input (as opposed to, say, converting 1000 images into 1000 single-frame videos).Any ideas on how I can connect the two—or, failing that, a better way to get files in a date range across several subdirectories into
ffmpeg
as an image sequence ? -
Resize/cut video to a certain region
18 mars 2023, par user3I have a series of videos (like 7k videos) in which I have to make a cut. Basically they are videos of people talking, and I have to cut said video and keep only the part of the lips.


Does anyone know how to cut them ? I need to be able to automate it


I'm looking for a command line software, where you can enter the coordinates and generates the new cropped video.


Is it possible to do it maybe with ffmpeg ? I couldn't find a way yet


Thank you !!!


I have tried to do it using ffmpeg, but I couldn't find the way to introduce the region (by coordinates) which I want cut

How could I add an overlay to a video based on mouse cursor coordinates ?
5 mars 2023, par DimaI am making a web app, where the user clicks through some images while talking about them and pointing things out with the cursor. The audio, timestamps of image changes, and mouse cursor coordinates and times are sent to a php script which uses ffmpeg to make a slideshow from the images and audio.


Then it runs another ffmpeg command to overlay a moving image representing the cursor hundreds of times to mimic the user's mouse movements.


Here is an example command that inserts the mouse overlay :


ffmpeg \
 -i ../tmp/6400d9c21a62d.mp4 \
 -i ../assets/mouse-circle.png \

And this is just from a four second video. When I tried to do thirty seconds worth of mouse movements, the command would not even run because there were too many arguments. So I need to come up with another way to add a mouse overlay.


An obvious choice would just be screen recording the user's screen to not have to add a mouse overlay because it would already be there. But then I don't think I can use full resolution pictures in the final video. It will be recordings of the images at whatever resolution the user's screen is set to. (Unless there's a way around this that I don't know about.)


So how could I take a long list of mouse coordinates and timestamps and add an overlay representing a cursor to an existing video ?


Edit : I tried putting everything from the
filter-complex
argument into a text file and calling it withfilter_complex_script
instead, as @БаярГончикжапов suggested in comments. Now it at least starts to run, but every time fails with this error :

[Parsed_overlay_1553 @ 0x55caae67f900] [framesync @ 0x55caae6802a8] Sync level 2

It only happens if there are more than 1553 arguments, and changing the arguments for 1553 and surrounding ones doesn't stop the error.
