- using Apple's aac engine
- new scaling algorithms
- mp4 file optimization
- support for any Quicktime codec
Now for aac encoding, it sounds better, it is faster, and even possible better sync (the old resampler introduced problems). The new scaling algorithms:
- Fast bilinear
- Bilinear
- Bicubic
- Experimental
- Neirest neighbor
- Area averaging
- Luma bicubic / chroma bilinear (default)
- Gaussian
- Sinc
- Lanczos
- Bicubic spline
Mp4 file optimization:
- moves the control information from the end of file to the beginning (let's you play a streamed file)
- reinterleaves the samples so that samples for a given instant in time are colocated
- removes any free blocks, so the optimized file can actually be smaller
About support for any QuickTime codec: while the app will let you choose any codec, obviously it will not work for a non-mpeg4 codec. It was found to work with 3ivx and Divx, though not Apple's mpeg4. Also the app will also let you chose any audio codec, but again, obviously only mpeg4 audio will work correctly.
