• Output a video with "slide up" transition using more than 100 images in FFMPEG ?

  9 juillet 2021, par Joseph Ladera Fugata

  I have more than a hundred images of the same size and format that my company wants to display at the big 9:16 (rotated 16:9) screen outside the front gate. It's supposed to be easy but they required me to have it slide from top to bottom, meaning that it should look like a smooth auto scroll effects. I searched here and there but no luck.

  


  I have tried xfade like this :

  


  ffmpeg -loop 1 -i input.txt -filter_complex
"xfade=transition=slideup:duration=10:offset=0,format=yuv420p" output.mp4


  


  It didn't do anything just a bunch of error referring to the inputs. Which is supposed to be just 2 images in the first place.

  


  The next thing I tried was using Concat from someone named @Gyan at his reply HERE and here's my version of the code :

  


  ffmpeg -y -f concat -safe 0 -i input.txt
-vf tile=1x%img_count%,loop=%_my_loop_count_var%:1:0,
crop=iw:ih/%img_count%:0:clip((t-%_start_time%)/%sec_per_img%*ih/%img_count%\,0\,ih*%img_count_minus_one%/%img_count%)
-r 25 -c:v libx264 -preset ultrafast output.mp4


  


  When I played with it, it gives a different output even do the image are all the same dimensions.

  


  I found someone on youtube used this but it is using bash and I am on windows. Unless someone here can convert it to a batch script would be great. I look into it and it seems like he's just V-stacking them kinda like what I did but there's more. I know I could have gone through win bash but I doubt the script will run on a non-Unix environment just by having bash, and I'm not yet familiar with Cygwin either.

  


  I also did tried other options posted by others here, I just forgot to bookmark them, but non of them works on more than a hundred images.

  


  I love to hear a response if anyone can help.

  


• Why is this ffmpeg conversion turning up trash ?

  12 octobre 2015, par DigitalJedi805

  So, the company I work for still archives some of our data in Windows Media format.

  I’ve written a C# application that loops through all of our WMVs, and in the event that a corresponding MP4 doesn’t exist, it fires off ffmpeg to convert the file.

  What I’m running into, is a combination of problems.

  When I run the following into ffmpeg ( rough C# ) :

  "-i " + File.FullName + " -vf scale=720:480 -b:v 512k -bufsize 512k -vcodec libx264 -acodec aac -strict experimental " + OutputPath

  I end up with a file that cannot play in our browser based player ( JWPlayer ), and cannot play on my local system in Windows Media Player.

  Additionally, the file is larger than my WMV, and is larger than the file I output with [roughly] the same parameters in AVS Video Converter.

  Furthermore, the file details don’t show any values for the video properties - as in, when I right click and go to properties->details, under ’video’, there is a list of length, height, width, frame rate, and bitrate - they are all empty - when I would very much expect some data normally.

  Does anyone have any idea how I can make the conversion more straightforward, or what might be creating the problem in the first place ?

  I’ve tried running this without scaling or bitrate parameters, and added them as an attempt to resolve the more core problem - obviously to no avail.

  For everyone’s appeasement...
