Importing vs. AMA

[Michael Phillips]

Depending on codec, AMA allows you edit directly from the sources being referenced. AMA with transcode is near real time versus a 2x longer real time with Import. AMA also allows you to select spans of clips to transcode rather than the whole clip.

What you don’t get with AMA is control over gamma such as RGB or 601/709 as part of the process. Also, don’t AMA BWF audio clips – it will work, but QuickTime really messes up the timecode inside the file.

It sounds like the best work flow is to import via AMA and then immediately transcode. I noticed there are different DNxHD resolutions depending on 1080 or 720 and frame rate.
Is it better to use the standard DNxHD or the one with the X?

What is BWF audio?

Thank you kindly for your time and knowledge.

The “x” denotes a 10 bit resolution. If your sources are 10 bit then you should – but most compressed format are 8 bit and will look fine as 145/120/115 for 1080.

BWF is a broadcast WAV file, the format recorded by audio field recorders like Sound Devices, Tascam, Deva, etc.

You also can’t modify the metadata in an AMA clip. I recently brought in large groups of DVCPRO HD on P2 cards, and need to assign auxiliary timecode to sync them. I couldn’t do it until I transcoded them.
