Non-rendered speed up/slow down motion timeline clips #890

Open houku opened 4 years ago

houku commented 4 years ago

so, just to point out, i did NOT come from adobe, and i WANT to use flowblade, but my editing involves speeding up the video and sometimes slowing down, now i KNOW theres a feature for that, but i dont like the fact i need to wait for my entire video to be sped up so i can show a montage, i know i probably need to change my workflow if the feature stays like this, but i would like to be able to speed up the video without making a separate file, kinda like you do in most editors, if that will happen, i will gladly move to flowblade 100%

thanks (thats my only problem at the moment)

Yes if you have a montage on timeline you probably need to render that out before doing speedup/slow.

Make sure that you are aware of the fact that you can render only parts of media items by the following workflow:

1) Open media 2) Double click to open media item in clip monitor 3) Set In/out points around area you want to slowdown/speed up 4) Select "Render Slow/Fast..." option with right click from media item 5) Select option "Form Mark In to Mark Out" for option render range.

I second this request. Even better would be if speed is a key-able attribute as in Blender VSE for instance or in http://slowmovideo.granjow.net/docs.html which would allow for smooth speed transitions.

This functionality has not been improved in quite some time so I think it is time to start looking into this again. I'm thinking 2.10 could see some work here, 2.8 seems not likely currently. The keyframed speed change editor seems doable, not sure if we will be using curves for this, depends on quite a few factors.

Now that we have timeline rendering this feature makes some sense because it will possible to do realtime playback on those clips. We could eventually get around to doing this but probably not on next cycle.
