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 / 29.970030i UFF
A52 Audio (aka AC3) (a52) / Stereo / 48000 Hz / Bitrate 256 kb/s
2 QuickTime files / 1280X800 / 59.912976 progressive
MPEG AAC Audio (mp4a) / Stereo / 44100 Hz
3 MPEG-4 files / 1920X1080 / 50 progressive
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?
How do you recommend that I deal with the mixture of interlaced and progressive?
This is a short film which I intend to enter into film festivals an eventually make available online.
Thanks in advance!

How do you plan on finishing? From the camera originals or transcode to the highest quality DNx and use that as final video quality?

I’m editing online-only. Not sure if that’s what you’re asking… if not, please explain!

That’s what I was asking. In your scenario, link to the files and transcode to DNxHD 115 at a minimum.

1) So, AMA-link and then transcode to DNxHD 115 at a minimum, working in one same project from scratch, right?
2) If i do this, AMA-link, transcode and then edit, I won’t need motion adapters, right?
3) Most of my footage is H.264 – MPEG-4 AVC (part 10) / QuickTime files / 1280X800 / 59.912976 progressive
MPEG AAC Audio (mp4a) / Stereo / 44100 Hz…. should the project be HD 1080p/29.97?
4) And how do you recommend that I deal with the mixture of interlaced and progressive?
Thanks so much for your help!

What’s your final delivery? Broadcast, or streaming? What frame rate? Interlace or progressive? Once that’s defined, it’s easier to work backward.

Sorry I didn’t get back to you for so long. I was caught up with work.
I’ll do my best to answer your questions:
– This is a short film which I intend to enter into film festivals an eventually make available online, so I guess my final delivery is streaming?
– As regards frame rate, interlaced or progressive… this is a problem for me, I find it to be a really confusing subject, I need your judgment here.
First of all, I’m not sure how to confirm if my different footages are interlaced or progressive. Cause I’ve read everywhere that many times MC/FC/Premiere misinterpret this piece of media info.
Can you recommend and effective method to do this?
Nevertheless… I’ve checked with Premiere and it seems like this are my different footages frame rates:
29.970030i UFF (I would assume this is actually progressive, but Premiere states it’s interlaced UFF, this is an JVC GZ-E10BU video camera footage)
I know I should match my project to be whatever my footage is (progressive or interlaced), but most of the footage is either 29.970030i UFF or 59.912976 progressive. Keeping in mind I’ll probably share this work in festivals and online… how do you recommend that I deal with the mixture of interlaced and progressive? Can you help me define this?
Should the project be HD 1080p/29.97p?
Thanks sooo much!
I’ll anxiously hope for your response!
I have a week off and wanna dedicate it to this project ☺

I agree that I would most likely make the project a 1080p/29.97 as delivery will be steaming or projection which is always a progressive delivery. TV’s are mostly progressive but there may be some old interlace tube TV’s still out there somewhere. ????
Now, when linking to footage that is not 1080p/29.97 native, Media Composer will convert to 1080p/29.97. Quality of frame rate conversion is always a debate – but a 59.94 to 29.97 will either lose every other frame or blend them. Try linking to a few different formats and transcoding in Media Composer to a high-quality codec (minimum DNxHD 115) and export out Same as Source and watch it play full screen in MoviePlayer and see how it looks. That will be your ultimate test for quality.

Like Michael said…do some tests. No matter what you end up with for the majority of your footage, you may still find a shot or format that you need to do different from the rest. (bring into its own project, then transfer over and play with the motion adapters, or run through something like compressor to do a conversion to your final format.
Keep your head up and make notes of shots that are going to need attention later in the process. Sometimes its only 1 or 2 shots, and there is nothing wrong with reconverting 1 or two shots after you have cut with them, and decided they need a different process.

Thank you guys!
I’m testing right now.
I’ll (most likely) keep you posted, cause I’ll (most likely) need your inputs again.
