"Missing or Broken index" when exporting RAW video
« on: February 18, 2020, 10:39:00 PM »
Hello,

I've been playing with the video export tools, but I stumbled upon a weird issue :
- If I export low resolution RAW videos, everything is ok, the video can be played in VLC or imported in a video editing software without any issue ;
- If I export high resolution mjpeg videos, everything is ok as well.

But if I export high resolution (4k or 1920x1080) RAW videos, VLC tells me that the index is "missing or broken", and a software such as DaVinci Resolve is not able to import the file. Allowing VLC to attempt to repair the index doesn't fix anything.

Any idea what could be the issue ? Is this a known issue ?

Hello Shadow,

Are you using RGB or RGB plus Alpha option for RAW video rendering?

Also please specify the OS version that you are using and the current screen resolution.

Hello Shadow,

Can you please send the example of such rendered video (can be short, if the error is still there) to support@agisoft.com? Meanwhile I'll try to reproduce the problem on similar configuration.

Hello Shadow,

Is it possible that VLC has problems working with files larger than 4 GB? Or probably there are issues with index data for large file caused by Metashape exporter. We will check that shortly.

However, your large file can be properly played in Windows Media Player, for example.

I don't think so, since the issue is also there using DaVinci Resolve (which even fails to display the files in their folder, or to import them using drag & drop).
I sent a sample to the support (ticket number 134696).
