What’s the difference between the trial version and the full version?

The free trial version of the app is just meant for trying the app out, and it contains some limitations. Videos outputted by the trial version contains a watermark and the app will cease to function after 30 days. The full version has none of these restrictions.

What formats are currently supported?

The primary goal originally was to support opening formats created by camera apps and those natively supported on Android, however the app has expanded to support a wider selection of formats:

Input Output
webm X X
mp4 X X
3gp X
m4v X
mkv X X
flv X X
mov X X
wmv X
asf X
ogv X
avi most X
mpg mpeg1

Can I play all of these formats on my phone?

All of these formats can be played by one app or another and there are apps that play basically any format, for example BSPlayer.

After I render a video using your app it won’t play.

This is likely due to the video player app you’re using not supporting the file. Due to very confusing nature of video formats, file extensions can even be deceiving (e.g. some mp4 files will play but not others). BSPlayer is a good free app that plays basically anything.

I purchased the upgraded version. How do I remove the watermark?

Unfortunately the watermark in the videos that were already produced with the trial version can’t be simply removed, similar to how changes to outputted videos using different tools (resizing, trimming, etc.) can’t be undone without going back and re-editing from the original video file.

When I try to “Share” with a certain app (Bluetooth, Messaging, etc.) it gives me an error.

The “Share” function of the app simply exposes all of the share functions of the apps you have on your phone, and a lot of the sharing functions on Android can be a little weird.

Unfortunately it’s not possible to address every app individually, although certain apps like YouTube and Gmail I make sure they work with the app. If you think there’s an app I should be focusing on, please shoot me an email.

What if I have other problems, questions, or suggestions?
