Gradual Playback Speed Increase?

[LGO]

I have a video shot from inside a vehicle driving down a rural French road. I would like to increase the speed to 110% to 115% as the video progresses to match the music I will overlay it with.

I know how to increase the playback speed, but I can't seem to find if it's possible to do it gradually. Everything I try increases the speed all a once. Is this possible (gradually increase speed) with the Playback Speed settings, or do I need to make two clips of the same segment, 1 at regular speed and 1 at the final speed, and use a long transition between them?

Any ideas on how to achieve this will be greatly appreciated!

I would suggest you cut the clip in segments and increase the speed in each segment.

Thanks for the reply, Dan.

Thought of that, but was hoping for something a little less than by "brute force" editing. Of course, I'm the same guy who will print out a wav form chart of music to sync photos and videos to crescendos of the background music. (which works better than any automated attempt at syncing music and images). This would be less effort than that, but hoped someone could enlighten me with a technique I haven't discovered yet.

Appreciate the response!

Anyone else have ideas

Unfortunately in VS, the only way to incrementally increase or decrease the speed is to cut the clip. VS's late, great big-brother program MediaStudio Pro had variable speed, which is done through keyframes. I think most consumer editors are not going to have this ability, the higher-end/professional editors do. They also carry a professional price tag..
