This is really a pity, because otherwise OpenShot is a great editor.
In light of my increasing video editing, I am sorry to say that I am beginning to contemplate switching to Windows for video. I spent the whole day today exploring video editing tools for Linux and it was a total disappointment.
1. Tried promising
Lightworks. However, it doesn't have an ability to synchronize audio to video on sub-frame level which makes lack of this one little feature a show stopper for me - I record audio separately from video and I need very precise sync later on. OpenShot does it easily and I always am able to sync precisely (video camera does record audio as well and I am able to perfectly sync audio and then mute camera audio track).
2. Tried promising
. Unfortunately, it does not support many video formats, at least on my machine and - most importantly - it could not read or render the files that my camera shoots (normal mp4 files). Internet search revealed alleged problems working with mp4. Video software that has problems with mp4... I just cannot rely on it and besides I could find no solution whatsoever.
