What version of the pylon package did you install? |

That's the Bonsai version, what I really need is the package version. You can check it by going into the package manager. In my case, I am running the 0.3.0. |

Haha! My apologies. I have the same version you just showed me, yes |

As the package description suggests, try to install the pylon runtime version 7.1.0. That should fix the bug. |

Well, previously I was trying to use the non-ffmpeg VideoWriter node but the .avi files tend to be massive and, more importantly, all of the videos I would obtain were minutes shorter than expected. The recording sessions are supposed to be one hour long, but I would be as far behind as 50–55-minute videos. |

Was the number of frames correct? Consider reading the discussion in #1112. |

Here is the link to the simple workflow. I apologize if I am ignoring something super clear, I am still learning this program: |

Downloading 7.1.0 as we speak. So, were you able to save a video? No issues at all? |

So, I was able to run the program after the Pylon update, but the main issue still persists. I got an unplayable video. It is approximately 43 mb in size, so it shouldn't be empty! But I can't open it with neither video player on my computer. This is what I see:
Do you think I am missing something under "output arguments" for the ffmpeg VideoWriter node? The expected resolution is 4024 x 3036, as these are the default on the Basler camera I have. |

I might be wrong, but I think the default ffmpeg codec for .mp4 only supports 2048x2048... can you try to resize your image (use the |

Hi again! So, I just resized the image to 2048x2048, as you suggested, and this works! Unfortunately, this only works with one camera. When I multiply this workflow for four cameras, the videos are of irregular lengths (a two-minute recording gave me four videos of different time lengths). |

How are you triggering the cameras? With a common trigger signal?

Curious, do I need to create a separate .pfs file for each camera?

Yeah, I simply press the Start button for now and recordings start immediately. My hope is to eventually create a workflow such that I can start the program and launch "preview" windows that would be waiting on my command (a key press) to start and stop recording after another key press |

Just to clarify, you are sending a synchronized pulse to the gpio of every
camera? How long after starting bonsai do you turn this pulse on?

Oh no, I am not that far yet. All I do is press the Start button on Bonsai. No pulses yet. |

If you are not forcing any synchronization between cameras they will likely
output a different number of frames and hence different video duration.

That makes a lot of sense, actually. Could you guide me in the right direction? Thanks a lot for your help so far, btw :) |

Hi everyone,
First time posting here. I have been trying for some time now to set up a simple recording system with one grayscale Basler camera. From what I have found on previous posts on this site, I was able to create a .pfs file through Pylon 5.1 for the PylonCapture node. I then added a MemberSelector node (called Image), which I got from other users working with the Basler cameras as well (I couldn’t figure out how to extract this property myself). Lastly, everything is connected to the ffmpeg-dependent VideoWriter node. The ffmpeg and Pylon libraries are installed, too.
The main issue I have been having is that I just can’t get a video to save. Previously I was trying to use the other VideoWriter node but 1) .avi files are massive and 2) all the videos drop A LOT of frames (all of the videos I would obtain were minutes short). I have found on other posts that I could use the ImageWriter node to save a video, but I still can’t succeed at this seemingly simple task. Could you guys please guide me in the right direction? I am hoping to eventually set up four cameras on separate boxes and then, if possible, run them all in the same workflow but independently from each other. I would much prefer to save my videos in .mp4 format. Additionally, I just discovered today that, after updating to Bonsai 2.7.2, an old error “External component has thrown an exception” is back when trying to start the workflow. I had this error before, but I solved it by downgrading to Pylon 5.1 and creating a Bonsai-compatible parameter file, as suggested here. Any idea as to why this error is back? I am attaching a screenshot that I hope will be useful in getting to determine the root of the problem. Thanks a lot, in advance!
