  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

So we shot an entire feature doc at a variety of different frame-rates on Red Epic and Scarlet. We were run n' gun so didn't have time to resync and slate. We were recording dual system. Now our producer wants to see all these clips in 23.976 FPS rather than 96 or 120. So basically no slow motion. Now our audio guy was recording but the timecode is so far off base that I have been laying out every segment of the shoot in a sequence in Premiere Pro, interpreting the footage in batches ( telling premiere to assume that a clips frame rate is what it was recorded at ) , and matching the audio to each clip..........Its so time consuming and tedious. Luckily its not airing till September so there is still time.

My hope is that I can export each audio clip to its corresponding video partner and attach it in Red Cine X. Is this the proper workflow? Any advice or anything? Kinda at my wits end....

I would recommend looking at DualEyes or PluralEyes, which is a plug-in for PRemiere Pro and other NLE's. It listens to the scratch track, and automatically lines up the high quality audio to match, and outputs a new "clean" timeline.

Bruce Sharpe demo'ed the new PluralEyes 3.0 at NAB, and the new plug-in and UI looks fast and easy to tweak:

There isnt a scratch track on the Epic/Scarlet stuff since its all in Varispeed so I have been matching dialogue by watching mouth movement ( its a Kung Fu Chinese dude ) and trying to match footsteps and other distinct sounds using markers in Premiere Pro.

CORRECTION:
It was all shot in varispeed.

Ouch. Without matching time code, or a scratch track, or matching-length audio and video files, I think you're on the right path. They will have to be manually aligned, using human eyes to spot matching A/V events. Even the "Synchronize Clips" command in FCPX won't work in this case. If the audio and video files are the exact same length (audio recorder was jam-synched to the camera, starting/stopping at the same time) then FCPX could be of some help, but if they are different lengths, no. I don't know of any automated tool that will, for example, look for a door slamming on a silent video clip, and find the matching audio event in a separate file. :-(
 
Yeah thats what Im doing now. Im on like hour 10 of the first day of footage.............. sad face facepalm sad face facepalm

So after this is done....once i align EVERYTHING. Should I head to RCX to attach the audio clips? I mean what if you feed a 96fps clip a 48000khz audio file? lol.............
 
Not sure if this would speed things up for you by getting you in the ball park, but if you could find the end of your audio and corresponding end of your video clip, then lay them both on the Premiere timeline, then adjust speed of the video clip until you get the video and the audio to line up, wouldn't that get your slow-mo back to normal speed and then line up with the audio? Haven't tried anything like that but intuitively it seems like it might work. Then, when you get the two clips lined up you could make your edit cuts on audio and video at the same places.

The issue is that the sound guy was recording all day. The cameras werent jam synced so theres no start stop. So far my workflow in importing batches of files ( sorting by Recorded Frame Rate ) into Premiere and Interpreting the footage to the Recorded Frame Rate, then sorting by starting timecode and making a new sequence at 23.976 per event. Its working. So now I get to see all the slow motion content in a realtime timeline...................but Ive burned through like 2 cartons of smokes.......
 
Yeah, In retrospect I was looking at it kinda backwards.
 
This may work, depending on your overall workflow:

In Premiere Pro, you can merge clips on the timeline. Once the audio and video are aligned, select both the audio and video, right-click in the timeline, and choose "Merge Clips." This will create a new item in your project bin that acts as a single clip.

NOTE: I believe there are some limitations to using merged clips, especially when going back out via XML. Double-check the help file on "Merged clips." (I'm typing on my phone right now and can't easily produce a link.)
