Video thumbnails gallery - failed to create new gallery

[BD.NT]

After a few latest versions, "video thumbnails gallery" feature keeps failing to create a gallery. Created thumbnails stuck at a few initial seconds and repeated the shot for the whole sheet.
As shown in the attached failed vs. successful example (generated by the MPC app).

PS My ver = 1.6.3 64-bit windows libformat 7.167

I'm so relieved it's not just me.
And I'm glad to know the team developer has recognized this bug, hence the hope of rapid resolution

Thank you

BTW I need to wait for 1.6.4 , do I ?
