Insert vertical smartphone video into FullHD Sequence

[benjaminj70996489]

I just started a new sequence with videos made with Sony ZV-E10 (FullHD 25fps) and some others made with my smartphone (FullHD vertical 30fps) but impossible to insert smartphone footages into the sequence. Any idea ? I joined the properties of the footages.

Many users are having issues with VFR. The file is Variable Frame Rate. Use Handbrake to convert to constant frame rate:

Here is a tutorial:

Shutter Encoder may also be used to convert to Constant Frame Rate:

I tried what you suggest but still not working. After a while, I saw the "Source patching for inserts and overwrites" was disabled by default. Now it works. Never happened in the past so sorry and thank you for the tips.
