Hello,

I am using BI 5.3.7.6 on Windows 10. I am successfully recording video streams "Direct to disc" .mp4 format, however whenever I try to open them (with VLC or Quicktime), nothing shows up.

In Quicktime, I get the error: "An Invalid Sample Description was found in the movie".

Codec shows up as H264 in BI but VLC, it shows up as H265.

Any advice or things to try would be greatly appreciated. Thanks!

Are you using Quicktime? A lot of the errors I found searching on that message seem to be related to using Quicktime.

"This error can be linked to the wrong Audio codec in the .mp4 container. Some encoders incorrectly put this as 103 rather than 64. One can use mp4ui or some third-party tools to change the codec."

Why would D2D have any format associated with it? Aren't those in whatever format the stream is coming from the camera in?

More generally, it is best to export clips you want to use outside of BI.

Hello,

Thanks for the responses. I have switched over to saving to the BVR format. When I do that, and then export from within BI to .mp4, the files are now opening.

I am not sure if this is an issue with the .mp4 format, limitation of the format, or the implementation of it from BI. We'll continue to monitor to see if any issues come up with it again. Thank you everyone for the feedback.

I forgot about the container format vs the stream/compression format.
