SnapMotion file diagnosis

SnapMotion
#1

I have hours of MP4 security camera footage that I want to extract for timelapse. Big Sur QuickTime can’t read it, so expectedly, SnapMotion can’t either. VLC and IINA and HandBrake all can. I was hoping the you’d see something in the VideoScan report as to why, so I can do the fastest and least invasive conversion into something SnapMotion and QuickTime can read.

Hi there,

It seems that your file is encoded as a MPG file whereas your file extension is MP4. That is why VideoScan add the row FileExtension_Invalid : mpeg mpg m2p vob vro pss evo.

Can you try to rename your file 2021-03-02 00.08.58.mpg instead of 2021-03-02 00.08.58.mp4?

Let me know if it is working.

Closer. Good try. SnapMotion doesn’t complain now, but it only plays a black screen. VideoScan still has the identical FileExtension_Invalid row. Tried .MPEG, too.

I am sorry for the delay. I did not see the notification of the reply. You can send me an email with a non-working video. I will check the problem.

No idea what changed, but it’s working now, in both programs. OS update, maybe Anyway, all good.
