I am Japanese.
I think that sentences are difficult to understand.
Currently, we operate such a channel.
I uploaded 6 videos so far but I can not upload new videos yesterday.
Despite uploading MP4 format video, the display "Please upload in the format of MP4, AVI ..." appears.
The video editing software you uploaded in the past is the same as the software you are currently using.
Please tell me how you can respond if you respond.
We've had a fault in the last 24 hours which caused uploads to fail.
This has since been resolved.
Please attempt to upload again.
