    Multi frame size and frame rates project workflow.

    Hi!

    I think this is the appropriate forum but please let me know if you think I should move this somewhere else. Also, I've not edited for almost 4 years now, so bear with me <3

    I’m working (or about to) on Avid 8.3.1, with 3 different footages.

    Codec is always H.264 - MPEG-4 AVC (part 10). But then:

    1 MPEG-2 files / 1920X1080 / 29.970030

    A52 Audio (aka AC3) (a52) / Stereo / 48000 Hz / Bitrate 256 kb/s

    2 QuickTime files / 1280X800 / 59.912976

    MPEG AAC Audio (mp4a) / Stereo / 44100 Hz

    3 MPEG-4 files / 1920X1080 / 50

    PCM S16 BE (twos) / Stereo / 48000 Hz / Bits per sample: 16

    I would first of all like to confirm I should AMA-link and then transcode (as opposed to importing). I’m assuming this is the way to go, since I’m working with camera footage and lengthy QT files (screen recordings), no graphics with alphas.

    I’m also wondering if I should create 3 separate projects that match the frame rate of the video files, AMA-Link, transcode them and then copy the Bins containing the AMA-Links and transcoded files into a main project. Or should I AMA-Link and then transcode in one same project from scratch? An HD 1080p/29.97 one?

    Now… which target video resolution do you recommend? What about audio format, sample rate and bit depth?

    This is a short film which I intend to enter into film festivals an eventually make available online.

    Thanks in advance!

    Re: Multi frame size and frame rates project workflow.

    Personally I'd lok at the most common framerate I think I will end up with in the final sequence and work to that.

    All the AMA sources will come in at their native framerate and get motion adapter in the timeline if needed.

    When you have a final sequence in one particular framerate (hopefully that most of the clips match) you can work on finding the best motion adapter setting to make the other clips look as good as needed.

    I'd then export that and convert that into non matching framerates.

    I'm assuming the 29.97 is Progressive (must be) and the 59.94 is interlaced (could be progressive but is a high frame rate)

    If so then you have to decide hyow to deal with the mixture of interlaced and progressive.

    Re: Multi frame size and frame rates project workflow.

    Hi Pat!

    Sorry I didn't get back to you right away...

    I'm based in Argentina, down south, Patagonia.

    I'm not sure I'm following you... you're saying I should AMA-link, edit and then transcode the sequence? I ask this because I'm thinking I wouldn't need motion adapters if my clips were previously transcoded, right? I'm editing online-only.

    I checked the media info on Premiere (I really don't know where to look it up on Avid) and my 29.97 is actually 29.97i UFF, while my 59.91 is progressive... how do you recommend that I deal with that?

    Thanks so much!
