Hi, thank you for your reply!
We noticed that the picture seems like being stretched horizontally and we will further investigate it.
About the crashing issue, could you please send us the in-app feedback and upload logs? Logs will help us dig into the crash and fix it. There is a feedback icon next to "Settings", you can click it to send logs.
Regarding some videos only have sound, we'd much appreciated it if you could send us one video for testing. Thank you!
