I'm looking for a simple video editing software for Windows 7 with the following requirements:
- Given a high-fps video (120fps), there is a simple tool to make a time stretch on a desired interval with smooth transition and correct audio stretching (no funny voices).
- Recompression artifacts are minimized. Ideally, no recompression should be made at all, only frame rate should be changed. (Are there any codecs with varying frame rate?..)
- Simple timeline crop tool, which does not cause recompression of the video, direct stream copy is done.
Any suggestions? At least for one or two items?
