I am combining older family video AVI 720-576 with later stuff from my present camera in MP4 - and Exporting my edited film as MP4 1920-1080 HD (using version 10.36)
My question is - is it best to edit and correct exposure etc in AVI first and export it as an MP4 clip to combine later with the others? - or does the export function happily apply all effects and transition from a timeline of both file types?
Would there be a difference in the final quality if I converted to mp4 first and then edited for exposure etc?
