I’ve just edited my first video with Shotcut. It went well, but two things surprised me: it’s quite sluggish when zooming the timeline or going back one second. The “go back one second” (with the keyboard shortcut) is especially frustrating because I might hit the PageUp key six times but it looks like some of those hits are being dropped because it doesn’t go back six seconds.
I was editing a two-track timeline: one track with video and audio straight off a camera, video was H.246 and audio was 16-bit PCM. The second track was audio off a phone and converted to a .mkv file, 32-bit floating-point PCM.
I’d like to know what, if anything, I can do to make Shotcut more responsive to zoom and movement, especially that “go back one second” key. Should I be using different video or audio formats? I would hate to incur the loss imposed by an extra conversion pass on the audio, but if I can speed up my editing process significantly, it would be worth it.
