How do I convert RMVB to MP4 on Mac?
Open Picmal, drag your RMVB files into the window, choose MP4 as the output and set your codec and quality, and click Convert.
Can I batch convert multiple RMVB files at once?
Yes. Drag in as many RMVB files (or a whole folder) as you like and Picmal converts them all to MP4 in one pass, each with its own progress.
Does converting RMVB to MP4 reduce quality?
Only as much as you choose. Picmal exposes a CRF quality slider, at CRF 18–20 the result is visually lossless. You can also trade quality for a smaller file when you need it.
Will the MP4 play on my iPhone, Windows PC, and the web?
Yes. Picmal defaults to H.264 inside an MP4 container, the most widely supported combination.
