Questions, answered
Which output format should I choose for a whole folder?
MP4 in nearly every case — it imports and plays everywhere, and consistency across a set matters more than the size saving. Choose WebM only when you are serving the files from your own site.
Can I convert files that are in different formats?
Yes. Mixed inputs are the normal case — MOV, MKV, AVI and others in one queue — and the output format is uniform regardless of what went in.
Does converting change resolution or frame rate?
Not on its own; those carry through from each source. If the files are going into one timeline, set a common resolution and frame rate as well so the editor does not have to conform them.
What if one file will not convert?
The queue reports the failure and moves on, so the rest of the batch still completes. Unsupported or damaged sources are the usual cause.
How is this different from the batch video processor?
This one shows only conversion settings, which is quicker when you know that is the job. The general processor covers both compressing and converting in one place.
