Is your feature request related to a problem? Please describe.
I have a raspberry pi cam which I use to stream a fabrication process to my network. For presentations I want to convert the long videos (up to a few hours) into a short <1min timelapse video.

The network-stream I've captured via VLC into an avi-file. When the avi-file is opened afterwards, VLC tells me the avi has a broken index. That's why I converted it to mp4 using xMediaRecode. This fixes the broken index message and I tried to import the new MP4 to screen2gif.

When starting the import using FFMPEG, I noticed, that FFMPEG stop importing after a few seconds. I observed this by checking the CPU load of the ffmpeg-process in the task-manager. It starts with 80-100% and drops back to idle (1-5%) after a few seconds. I tried to wait for more than 30 minutes, but the progress bar of screen2gif was not doing any progress anymore.

Since screen2gif didn't showed me any output what's going on, I tried to use it directly via powershell. Using:

./ffmpeg -i "<Path>\<to>\<video>\Saphir Segmented Cut.mp4" -vf fps=1/3 "<Path>/<to>/<extracted>/img_%06d.png"

With this command FFMPEG extracted without any problems and, in addition, I just got the wanted timelapseframes, instead of importing all frames, which most of them are deleted afterwards directly.

Describe the solution you'd like
Therefore, options or a textbox to customize the import process with FFMPEG would be great. Especially the fps-option of FFMPEG which allows the extraction of one frame each Nth second, e.g.: fps=1/4 extracts one frame all 4 seconds.

Preview on/off
FFMPEG options or a textbox to specifiy the options as arguments
- Especially the fps option would be great to speed up the import significantly (e.g.: fps=1/4 imports one frame each 4 seconds)
An output windows for FFMPEG to see what FFMPEG is doing.

Describe alternatives you've considered
I used FFMPEG via powershell and was able to extract just the frames I need for my timelapse. These I imported than as a image sequence into screen2gif to fine-tune the frame duration and create a timelapse-MP4

Nice feature request!

I could also use the improved framerate controls for the normal import process as well.
Maybe I can add something like what's used for the recorder, a field for numeraical values and a selector with perSecond/perMinute/perHour.

Heyho ,

thanks for the feedback. That would be great!

Just for completeness, for the moment I wrote myself a small workaround powershell script which asks for the

Path of the input file,
how much images should be extracted per second (given in FPS) and
Folderpath where to store the extracted images

for the codeline of my initial issue comment:
./ffmpeg -i "<Path>\<to>\<video>\Saphir Segmented Cut.mp4" -vf fps=1/3 "<Path>/<to>/<extracted>/img_%06d.png"

Content of my FFMPEG_Extractor.ps1:

$vidPath = Read-Host -Prompt "Insert video path"
echo "Extracting images from: $vidPath"

$fps = Read-Host -Prompt "How much images (in FPS)"
echo "Extracting images every $fps FPS"

$imgPath = Read-Host -Prompt "Define a storepath for the images"
echo "Extracting to $imgPath"


echo "Running FFMPEG:"
echo "C:\ProgramData\ScreenToGif\ffmpeg.exe -i $vidPath -vf fps=$fps $imgPath\img_%06d.png"

C:\ProgramData\ScreenToGif\ffmpeg.exe -i "$vidPath" -vf fps=$fps "$imgPath\img_%06d.png"
Read-Host -Prompt "EOS. Hit enter to close..."

Kind regards,
Deph
