Title: Blink - Unable to Create Video
Post by: dcarr on 2019 May 28 09:10:35

I am currently unable to create a video using Blink.

The situation is as follows:

1.   Blink initially failed because ‘ffmpeg.exe’ was not present in ‘C:\Program Files\PixInsight\bin’ on my system. I am using the latest update of PixInsight (01 08 06 1475); not sure of the software distribution arrangements for ffmpeg.  So, I downloaded the 64bit version and stored the executable in the required folder.

2.   With the ffmpeg executable in place, Blink did produce the png files (Blink00001.png onwards) using the default arguments (-y -r 25 -i Blink%05d.png Blink.avi). However, after creating all of the png files, the ‘Make Video’ window displayed “Could not open 'Blink%05d.png”. 

3.   Replacing part of the argument with “Blink*.png” enabled further progress but ended with the error: “Blink00001.png: Unknown file format”.

4.   There were posts in 2015 and 2016 on a similar situation:


Using the suggested arguments in one of the posts "-r .5 -i Blink%05d.png -c:v libx264 Blink.mp4” gave the same results as in steps  2 and 3.

Any suggestions?
