Liquid 7.1 handling of 24p and 25p

Andrew asked how Liquid handled 24p.

My guess was that for each second of media, all 24 frames and 36 Repeat Flags were captured to a file. This meant the clip would have a 59.94fps timebase. And, it should mean that when 60p comes, it will be captured correctly. Likewise, 25p and 50p should fine. The Timebase is, as it should be, "auto-sensed" from the media. No need to rely on, or create, Capture Presets as FCP requires!

The input clips are auto-sensed as MPEG-2 and the MP2 audio is auto converted to a WAV during capture.

Once a clip is in a 23.98fps Sequence, I assumed Liquid would correctly ignore the Repeat Flags. Which means 25p, 50p, and 60p should work fine.

When creating a new Sequence, again Liquid does the smart thing. You can choose 720/25p or 720/29.97p HDV Presets.

If you choose "720/25p HDV" you then simply leave it at 25fps, or change the FPS to 24fps or 50fps.

If you choose "720/29.97p HDV" you then simply leave it at 29.97fps, or change the FPS to 23.98fps or 59.94fps. Now select Drop Frame.


You can also choose 1080/50i or 1080/59.94i HDV Presets.

If you choose "1080/50i HDV" you then simply leave it at 25fps, or change the FPS to 24fps.

If you choose "1080/59.94i HDV" you then simply leave it at 29.97fps, or change the FPS to 23.98fps. Now select Drop Frame.

And, no I haven't tried 24F from an H1. But, it since Liquid auto-senses the frame rate, it should capture a 23.98fps clip.

If you choose an HDV preset, you automatically get an MPEG-2 sequence. And, on export, the WAV audio is automatically converted back to MP2.

By the way, you can simply choose frame-size and fps and use uncompressed 4:2:2 if you wish.

Lastly, the Deko CG is miles ahead of FCP's Text Generator.
