Final Cut and Quicktime

jonaent (Jon) If you have a fast computer then edit in HD and then when it's all finished export using compressor or some other such software to a lower res - that way you will get better overall pixel depth and quality, rather than exporting an already smaller quality file.

More +1 action.

But . . . .

Remember a slow computer (slow processor) will be much happier and faster with massive uncompressed files rather than smaller uncompressed files.

Give a slow computer an uncompressed QT at 8 or 10 bit - or Animation codec at 100% - or PhotoJpeg at 99% (100% pushes the colour space over into 4:4:4 which the Panasonic HDC-SD5 does not resolve) - or any other lossless or very lightly compressed format and (if the drive they are on is fast enough / ie: most 7200rpms) then things will run a lot smoother than if your source footage is compressed.
