I created a 1500x1000 1000-image set: Sequence_000.png -> Sequence_999.png. This loads fine using at the start of the command line: ffmpeg -i Sequence_%03d.png This will also work if the sequence numbers are inside the filename: ffmpeg -i 0191107-154%03d-214.png But if you rename the first 5 files to: _Sequence_000.png ... _Sequence_004.png it will fail because the first file starting with Sequence is now Sequence_005.png. Renaming _Sequence_004.png -> Sequence_004.png will allow the remaining 995 files in the sequence to load. If you can not batch rename the sequence to start from 00 or if it is a non-contiguous list because you deleted some damaged/missing images, you can tell FFMPEG to load a list of filenames. This has to be in a particular 1 or 2-line format (if including image duration). For example, I've deleted the first 83 images, substituted a Replacement.png, and the remaining image names jump by 3. Then I created a list of filenames. To create such a list in Windows, I use create_list.bat, here designed to look in the "Sequence Directory", beneath the current directory ("C:\test directory"), where the images files are situated, create a 2-line name-sorted list where the 2nd line is the duration in secs (1 frame at 25fps = 40ms), and then load this list in the associated text editor so you can delete or move blocks, change durations etc., if required. @echo off SETLOCAL EnableDelayedExpansion if exist mylist.txt del mylist.txt for %%I in ("Sequence Directory\*.png") do (echo file '%%~fI' >> mylist.txt & echo duration 0.04 >> mylist.txt) start /i mylist.txt The first 4 files in the list: file 'C:\test directory\Sequence directory\Replacement.png' duration 0.04 file 'C:\test directory\Sequence directory\Sequence_0083.png' duration 0.04 file 'C:\test directory\Sequence directory\Sequence_0086.png' duration 0.04 file 'C:\test directory\Sequence directory\Sequence_0089.png' duration 0.04 If you decrease the duration below 0.04 @25fps FFMPEG will start to drop frames. Conversely, if you go above 0.04, it will start to replicate frames. To use this list: ffmpeg.exe -f concat -safe 0 -i "C:\test directory\mylist.txt" -maxrate 30000k -y "C:\test directory\Sequence directory"\map_video6.mpg Dan. * * _______________________________________________ ffmpeg-user mailing list email@example.com https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
