Exporting separate frames, besides MP4

I would like to propose a simple checkbox in the movie export window that would allow the frames to be dumped as a jpg/bmp/tga sequence.

Why: I'm using the 5.3 demo and it, unfortunately, crashes a lot on my system (could be my drivers, but not very important, I'm sure newer versions will be better). I had a nice animation test setup and on 99% of my render it did a blue screen and died. I'm seeing Lumion uses FFmpeg to build the MP4 and my guess is it uses some memory stream to feed FFmpeg the footage, as I can't seem to find some temp dir which Lumion uses to render to and then compile afterwards.

But after the crash the animation is lost, and a rerender is needed. 10 minutes lost is no big problem, but what if I render all night on a big scene, only to find it crashed at 75% at 4am. I understand it causes huge files (I'm used to that) but 75% of my render was still useable, and I could even resume.

The mechanism to save a single image is already build into Lumion, so that should not be a problem, to me it would be an extra checkbox on the render animation tab, and it could just render the files to the same folder using the same name. If you have movie_a_flyby.mp4 the sequence would be movie_a_flyby0001.tif (etc).

Hope this makes sense! Together with the camera import request it would work very well in a 3D composite pipeline. Because right now it means we need to decompile the MP4 to a image sequence and that implies a quality loss. We always want to obtain the highest possible pixel quality.

Thanks for reading!

If you mean video to be exported to images sequences/frames it is already supported. Resolutions up to HD to JPG, higher resolutions to PNG.

Oh really, is it a Lumion 6 feature then? Demo is 5.3.
If so than great!

Has been in there at least since v4 ;) Look for video tutorial 03.22

Well sounds like your graphics card does not like Lumion for some reason. May want to see if your graphics card is supported. This of course lead to you upgrading other components such as RAM and the processor and maybe even the motherboard if necessary.

But, if it all is relatively new, I would ensure your PC meets the minimum recommended spec to run the program. It will bog it down and crash it every time if not and that has to be frustrating.

Hi jhn

Export as images, been there forever.

Further to trick and tremainr replies.

Having crashes is not good.  In our experience it's a hardware issue, either GPU or system in general, is not fully compatible with the requirements of Lumion.  The v5.3 Demo is quite stable.  You should check:

1. LUMION 5: Minimum hardware requirements.

2. Lumion Web Site: Specifications.

3. Passmark: Videocard Benchmarks.

You can attach to a post the LUmion DXDiag Report (Files -> click on Summary Chart -> Run DXDiag Report) so we can advise further on suitability.

Most important though is to ensure you have current GPU drivers on your system.

Ah, I totally thought the images tab was meant as settings for export a single frame, never gave it a second look. That is really awesome, some extra channels in there too!

As for my machine, it's a skylake i7 with 32GB DDR4 ram and a 980Ti with 6Gb ram. Lumion says it really likes my system specs ;)

It's not the hardware in the sense it's not fast enough or anything. I would think it's either windows 10 and maybe the fact I have my system overclocked a bit on bus speed. I get IRQ errors and such (blue screens).

Also it seemed to crash more on my imported geometry, can flaky mesh/normals cause instability maybe?
I need to test a bit more, but I'm impressed so far!

Is there a mail address I can sent the dx report to? I'm not big on publicly sharing 'personal' data, thanks!

Hi Johan, no need for your DirectX diagnostics file - your system sounds great. However, you might want to stop overclocking your PC to see if this stops the bluescreens from occurring. You should also try to figure out what's causing the BSODs, e.g. with BlueScreenView.

Regarding crashes during importing, if you have some files that consistently make Lumion crash when importing them, I'd be grateful if you could follow the instructions in the sticky post on reporting import/export issues (including uploading the files). It is possible that the issue has been fixed in a later version of Lumion (as I assume you're still evaluating the demo version, i.e. 5.3). Thanks in advance.
