A video showing what I am doing: 02.08.2022_18.14.00_REC
Also, I’ve rendered using both Movie Queue and Legacy. For both I get the same error.

Help pls!

Hi HBesso,

1920x1080 seems like a very reasonable output resolution, but do you still crash if you set the resolution very low?

A few paths forward:

If you go to your Unreal Engine installation options (drop down next to ‘Launch’ on engine version) you can download ‘Editor symbols for debugging’ (50GB) With the symbols you should be able to get more information in the crash window. (Instead of just “UnrealEditor_Sequencer” in the crash log it should point to the precise file/function)

This extra information might give clues as to what settings to change for a successful render. PLUS it will be helpful if you choose to enter a bug report.

But, for a bug report you’ll need to be able to reproduce this crash from a new project. Feel free to post the repro steps or a minimal sample project, (File → Zip project) and I’ll give it a try on my PC.

Cheers

Ok. I’ve downloaded the Editor Symbols. Uninstalled UE and installed in a new drive (I wanted to do this before, so I found it proper to do it now). Here is the error with details. Could you @astrotronic help me understand what I did wrong? I have a cinematic there that I needed to deliver yesterday :frowning: Pls help.

Thanks for that,

I cannot help you understand what you did wrong, getting this ‘deep’ for me is like trying to understand hieroglyphics. :slight_smile: The next step down the C++ rabbit hole would be figuring out what ‘SectionAreaView’ is and what tool tip the code is referencing in ‘GetSectionToolTip’. Then again, It might be something higher up in the callstack that’s causing the crash.

SSequencerSectionAreaView.cpp (You’ll need a github account linked to Epic to see code on github)

Consider creating a copy of your project and changing settings, doing basic renders, deleting parts of your sequence until it stops crashing etc.

If you need to deliver a video, what’s stopping you from recording the video from the editor? (Press F11 to go fullscreen!)

Thanks for your quick answer!
Unfortunately, it does not allow me to be 5 secs within the sequence anymore :frowning:
I’ll do it all over again.

Hey did you ever find a solution for that error? I’m facing the same issue

Is there a solution to this?
