Arriraw Converter - Thumbnail generation failed.

[Nuno Santos Lopes]

Hello all,

My name is Nuno and i work as a DIT in Portugal.

A few day ago i was in a job shooting with an Arri Alexa SXT and i experienced a weird issue in Arriraw Converter...

i use Arriraw Converter many times...

this time i had this error message, you can see it in the annex pictures, only in the first clip of some Reel's...not all...

The error was: Thumbnail generation failed, and Error reading look LUT data from buffer. Incorrect buffer size.

We were shooting Arriraw, 2.8k, 25 fps.

The weird thing was that this clips were ok, i work with DaVinci Resolve and all footage was ok,

but i could not read them in Arriraw Converter....

(I'm using the last version available - ArrirawConverter 3.4.5.4)

why?

Many thanks.

Cheers.

Dear Nuno,
we'd need further data to investigate the error.

- which version of the Codex Production suite are you running?
- can you upload a sample *.ari file somewhere or mail it to digitalworkflow@arri.de?

Thanks,
Jan

Hi Jan,

i was still using Codex VFS, since the camera was a SXT upgraded from a XT, still using Codex Capture Drive XR.

(https://codex.online/products/media/capture-drive-xr)

And i was using a Codex thunderbolt Capture Drive Dock.

I've sent one .ari file to email you told me.

Thanks.

Cheers.

....also....

we were shooting with anamorphic lenses. HAWK.

The clips i could not open were always the first one of the reels, and not all reels...

The arriraw footage was all ok, since i could browse it, play it, grading it and converted it without any issues.

Thanks.

Dear Nuno,

the error lies within the Virtual Files System, it is simply too old for a proper SXT ARRIRAW workflow and clean metadata handling.
Make sure you switch to the Production Suite.

Best,
Jan

Hi Jan,

Thanks for you reply,

just to check...

that's only an handling issue issue? right? (the footage was ok...)



Thanks.

[Jan Heugel]

Yes, totally; a handling issue caused by the outdated VFS.

Best,
Jan
