ADB screenrecord issue

I use adb screenrecord to take screen captures.

It worked fine up until HorizonOS v72, but after upgrading to v74, the aspect ratio of the captured image is lost when capturing at a specified size. Example:

>adb shell screenrecord --verbose --size 480x640 /sdcard/demo.mp4

>adb pull /sdcard/demo.mp4

Capture of V74

I'm now in big trouble because up until v72 the aspect ratio was maintained when outputting.

Traditional Capture

What could be the cause?
