Filmora is the best video editor app for the beginners as well as who all r professionals, because filmora gives you two options if you want to do edit fast you can use easy mode but it will be with less features or else u can use full feature mode where u will get full features and your editing will be better.
This app has really helped a lot of people who dont know how to edit a video a because of it they have learned it and are utilising their skills to earn money. Filmora provides you audio format of mp3, m4a etc any many more with photo format of. Jpg, . Png , etc
You can also import the photo from your social media and can use it for ur video editing. After editing video u can upload the video on social media or any where else u want.
According to my personal experience I would prefer if u are a bigener user filmora and enjoy video editing.
