I dragged an .mp4 video clip I had downloaded (from Pexels) into the Playlist, created a Video Track and dragged the clip to that, and when I tried to apply the Time Remap filter, got the message that the video clip contained ‘B’ frames, and therefore needed to be converted.
So, I converted the clip - first to Best, then to Better, then to Good - and each time tried again to apply the Time Remap filter.
Even though the filter dialogue appeared, there is no ‘Stopwatch’ icon, and no tick/check mark next to the name of the filter in the filter window.
Also no ‘Keyframes’ tab anywhere.
In short, it looks like I cannot apply the Time Remap filter to the video after converting it to .mkv, .mov, or .mp4.
Any ideas here, about how to successfully apply the Time Remap filter, and/or how to ‘treat’ or prepare the video clip so that it will convert correctly?
I am feeling a bit red-faced right now, because I had been looking for the keyframes tab at the bottom of the Shotcut window to appear when I invoked the Time Remap filter - I never thought of (and probably never noticed in the Time Remap and Keyframes videos I have watched) clicking on the Keyframes button in the menu bar across the top of the screen to get the Keyframes features to appear.
Will try that, and will report back.
Thanks for the videos - yes, I have seen both of those, and have watched several others, some of them repeatedly, to get the concepts and application of those concepts into my head. I really like Joe’s videos, in particular.
Clicking on the ‘Keyframes’ button in the top menu did the trick, in terms of being able to apply Keyframes - thanks for that.
I do, however, have one remaining question:
When I right-click on the diamond shaped keyframe type (in order to choose ‘smooth’ as an alternative keyframe type), ‘smooth’ is greyed-out; ‘hold’ is clickable - how do I get ‘smooth’ to be an option that I can choose for the keyframe type?
In Joe’s video, he demonstrates how to simulate the ramp effect with a small handful of linear keyframes. I think it is pretty compelling. I think our senses are less sensitive to step changes in speed than volume or brightness (for example).
Right. He’s simulating one. It’s not actually Speed Ramping. Also I wouldn’t say it’s compelling considering that it takes him a while to even get that simulation going. That’s why he edits out the rest of his efforts in getting that set up and cuts to the end result. And of course, he is only doing that as a workaround because there is no way to smooth out the keyframe animation.
