If you want to do slow motion, shoot interlaced, even if your final project is going to be progressive. It is more important to have twice the samples per second than full vertical resolution. Compressor is better than using the Clip Speed feature of Final Cut – if the footage is interlaced, FCP throws a field away first before doing any frame blending.
Export your clip as a QuickTime movie.
In Compressor… If you want half-speed, in the Frame Controls tab, you only need use frame blending because Compressor turns each field into a frame:
If you want to slow down further, set the duration to be longer, you’ll need to use Motion Compensated retiming:
This will take a long time to compress, but should produce good results.
1. Original footage.
2. Final Cut Pro 1/2 speed version: ['Speed...' from the Modify menu] This throws away one field for each frame and creates new frames by blending existing ones.
3. Compressor 1/2 speed frame blended version: Takes each field and deinterlaces to produce a frame.
4. Compressor 1/4 speed motion compensated version: Looks at each frame to see in which direction groups of pixels are moving – creates new frames based on these guesses.
5. Compressor 1/4 speed high quality motion compensated version: As before, but spending more time analysing the pixels in each frame.
6. Compressor 1/8 speed high quality motion compensated version: As before, but slower. This shows that 1/8th speed doesn’t work with this kind of footage, but it does ‘go wrong’ in an interesting way.
