Questions
Anything else? Write to contact@doetra.com.
Is Doetra Video Studio really free?
Yes — every tool is free with no watermark, no signup and no file-size paywall. Your own device does the processing, so there is no server cost to pass on to you.
Are my videos uploaded anywhere?
No. Videos are opened, edited and exported entirely inside your browser. Nothing is sent to a server, which also makes it much faster than tools that make you upload first.
Can I combine several edits?
Yes — that is the idea. Drop your video once, stack edits like trim, resize for Reels, add text and fit under 16 MB, then export once. Every edit is applied in a single pass, so it is fast and loses less quality.
Which formats are supported?
You can open MP4, MOV, WebM and MKV videos (H.264, HEVC, VP9 or AV1, depending on your browser). You can export MP4 or WebM video, GIF, MP3, M4A or WAV audio, JPG/PNG stills and a ZIP of frames.
Is there a size or length limit?
There is no fixed limit. Very long or 4K videos take longer and need more memory, so on phones we recommend videos under about 10 minutes. GIFs are limited to 60 seconds.
Does it work on my phone?
Yes — it works in modern mobile browsers on iPhone and Android and is designed for touch first. Exporting uses your phone's own video encoder.
