I run a website that has offered downloadable instructional videos for 7 years. We have traditionally supported both mp4 and wmv formats.

I would like to simplify my life by just offering one format if possible. Do I still need to support wmv format? Or is this still an issue?

If I could support one format, which would it be?

MP4/h264 is widely supported today. I'd even say it's the most supported video format since the existence of digital video (without having actual statistics to back that claim). There is really no reason to deliver .wmv anymore when targeting a multi platform audience, the version of Windows Media Player that came with XP doesn't support MP4 but newer versions definitely do and the market share for that version should be very very low. Most users have adopted third-party players like VLC and even companies usually install atleast one third-party video player on their computers that will very very likely support MP4. MP4 has wide hardware playback support (unlike wmv) and runs without any issues on any platform (unlike wmv).

So yes, in my opinion it's absolutely safe to only deliver MP4 videos as long as they are properly encoded. Using Level 3(.1) would be a safe bet, its supported by practically any software and hardware that is capable of playing MP4/h264.

Anything playing on an old iPad 1 will work on most probably any device.

I think "main profile" was important when encoding, check for details here:

And always try on a real device ;)
