CHV TimeControl for Mac

From chv-electronics:

• You can define up to 9 markers
• Set a speed for each marker
• Smooth frame-blending

TimeControl will show you on two timelines in the canvas how the speed of the clip changes over time.
No cutting off anymore. TimeControl's length can be changed in the timeline. That way clips you want to slow down, won't get cut off at the end and you can also see the ladder part.
TimeControl can very easily handle progressive-scan footage.
An additional build-in FlickerFilter will avoid flickering when you slow down interlaced footage.
Frameblending can be switched on and off.
Frameblending can be adjusted very easily when you end up with frame no. 42.76 (for example) after a speed-change but you need frame 42 or 43.
An additional offset-slider lets you slide your clip without razor-blading it.

Included in the collection is also the Speed-filter. An easy tool to go "back and forth in time".
