I created two HD videos. One had a full size preview, the other had a much smaller preview. It would be better if they were always full size.

The preview of some clips becomes red randomly. I seems to only happen on clips made from my iPhone 8 OR clips that are longer.

All software is up to date.

I noticed that when I disconnected the Adobe Cloud sync, the red screen issue disappeared briefly.

I want to be able to simply move my finger vertically down on the timeline to split a clip. Same function as the scissors icon but simpler.

One of the useful features of iMovie is the ability to scroll the timeline by moving your finger left or right on the video image. Tapping the image stops playback.

Very useful for choosing a cut point.

I want to be able to stop anywhere on the timeline and have the ability to add media at that point.

Currently if I choose a new shot it adds it at the next cut point or puts it on the end of the timeline. I end up having to then move the clip to where I want it.

It would be much better to have options when adding media such as:

Insert audio / video at playhead

Overwrite audio / video at playhead

Add video on Video Layer 2 / 3 at playhead

Add audio only at playhead

Thanks.

It would be great to have a shortcut to quickly review the most recent cut – by going back 1 or 2 seconds before the edit and hitting play.

This would drastically speed up editing time, as I wouldn't have to keep clicking a few seconds before the most recent edit to review it.

Pretty much the most issued command is simply play.
This needs to be way easier than hitting that small triangle button everytime.
Two finger tap Right on the Timeline or whatever, you get the idea.

I have a project I have been working on. when I try open the project to edit it the audio will load but the video won't. it just shows the preview as blurred out and a black screen.

On IOS, I would like to be able to choose which video track the shot is added to. This way I can build a sequence of cutaways over an interview for example. The interview would be on V1 track, cutaways added to V2 track.

Would also be really useful to be able to add just the audio from a clip.

To be able to make any adjustments to the geometry of the clip a pre-set - for instance, if you add the letterbox effect manually to one clip, being able to do it for all clips would be helpful.

I'd like an easy way to replace footage. E.g. right-click footage on the timeline, choose "replace" or "relink" or something similar. And then choose a different video. Afterwards a message could appear that asks me whether I want to retain the current timeline timings, avoiding that the rest of the timeline moves if I place a longer/shorter clip. Or if I want to place the new footage as is, resulting in the total timeline growing or shrinking.

I’d love to see a split or cut option so that I can go to a part in a clip and cut the bit I want to use.

I would also like to see the ability to go to a clip in my project and set in and out points before adding it to the timeline.
