PanoVideo Converter (free) It's based on ffmpeg. But no scripting. Simply make settings. It's produce .mp4 .webm .ogv from any source file in any combination.
Or better - PanoVideo Creator. based on converter. It's also make posters, tour.xml, preview navigation and so on.

Hi Klaus,

ffmpeg is great for the job but I'm getting lost in the commandline settings!

In the Pano Video Converter, on clicking convert, a command line window opens but closes immediately and nothing happens. I tried with all the possible settings.

Could kindly share the line to use to convert an mp4 1920x960 to 2 webm files one same size and second 1024x512 as you use in the panovideo examples?

Hi Islander!
ffmpeg script generally will look like this:
ffmpeg: input.mp4 output.webm
But it is only the start of troubles. Because:
1. you need to work with command line
2. you need to write input and output path
3. you need to prepare separatly each webm and mp4 files in different qualities
4. additionally you need in posters - 2 qualities
5.Perhaps you want to prepare audio for iphone
6. No batch files. You need to prepare all sets of files for each video. It means repeat operations for each file
Panovideo converter is free program and it takes care to do all this operations and provides you with wysiwyg interface.

Hi Islander!
as you have edited your post I can write you additional information This information from TourCreator may be useful for you, as well as for others.



Don't try to convert video from krpano examples version 1.19.4 and higher. This file is protect from convertation.

Of course we can remove protect information. But among other it will
mean that anyone can download any video from net and create his own
panovideo tour. We think that it is not the good approach.

So, try convert your own video or find on your computer archive file from version 1.18.5 or earlier and try it.

This video (part 2) demonstrate how you can convert video files with PanoVideo Converter.

Hi Denis,
I appreciate your help.
I've freezed a video capture of the error appearing in the blink of a eye.

As you notice the error reads: no such file or directory. I think it has nothing to do with the file being locked. It's not the sample video; it's an equirectangular video that I could even upload as vr360 to youtube.

I would really like to use the PanoVideo Converter for its simplicity. Anyone experiencing this is welcome for comments.

Hi Islander!
Great job. Not easy to get this picture.
You are the first who report about troubles in converting formats with ffmpeg.
There are few variants for this. Either file protected or it is corrupted.
Please, give me your file. I can see what wrong with it.
Best regards.
