Multi Cam-2 different cams, 1 audio: Use many gigs on drive?

Hi
I did a number of interviews using 2 cameras (DSLR & HDV) and the Zoom H4n.
For each interview I'm thinking I'll create multi cam 'clips' from the 2 cams and 1 separate audio clip.
What happens? Will this involve much transcoding of the video? Will it use many gigs on the drive?
If so, would synchronizing the clips be a better way to go, and is there a method to switch between cameras that way?
Btw, I made my first and there seems to be beau-coup activity going on on my MBP and the drive. Hence these questions.

Thanks for the reply!
Yes, all my media are on an external drive. I see it created optimized media of the dslr clip. It appears optimizing of the 29-minute clip created a file of around 40gigs. I don't think I can use multi-cam on this project unless I proxy it.
How are optimized or proxy files named or designated so as to be different than regular files?
Any way to trash the optimized file? Or proxy files if so desired? Are proxy files 1/2 or 1/8 of original file?
Just curiously, can regular and proxy material coexist in the same project?

Can the usb camera converter be used with a flash drive or scaning device?

can the usb camera converter be used with a flash drive or scaning device?

No.
iOS does not have scanner drivers nor does the connector supply enough power.
Flash drive would kind of work, would need to have a DCIM folder-probably wouldn't see whole drive(?)
Then again this exists, uses wifi:

Is it possible to transfer i-tunes using 4 gig pen drive?

I was following directions to back up my itunes library on an external hard drive and I thought I could just transfer my songs using a pen drive to a new computer. Before I actually try it, is this feasible or am I just making it hard on myself?

If your library will fit in 4GB, sure, this will work. For instructions, see these:

Clip audio gets quieter after enabling multi-cam.

I have a sequence with two video tracks and one stereo audio track (recorded separtely and synced), and placed it into my "main" sequence for editting. Before enabling multi-cam, the audio levels are noticibly higher, and once setting multi-cam to enable, the volume levels drop about 2-3db. I then have to raise the volume to compensate for that. Is this a bug or something particular about the way multi-cam clips are handled?

This is normal. Multicam by default only uses Audio 1 of the source sequence.

Issues with creating multi camera sequences

I'm using Premiere Pro CC 2014.2 and I’ve just started experimenting with multi camera sequences and have two problems, one I can work around, the other I can’t.
First, if I take a series of video clips, add a marker to each clip to identify the sync point, name the marker, and subsequently create a multi camera source sequence, the option to use the marker as the sync point is disabled. If I leave the markers blank and don’t name them, it works. Is this a bug or intended behaviour of the application?
Second, and more problematic for me; if I create a multi camera source sequence using two or more video clips, all of which have a stereo soundtrack except for one clip, and that single clip has a 5.1 soundtrack, I cannot seem to force the sequence to use the audio from only one of the clips with a stereo soundtrack. Basically I want the audio to always originate from the first clip (camera 1) during the clip selection process. I’ve selected the clips in the right order and ensured all other settings are correct, but the 5.1 clip always take precedence.
If all the video clips contain the same format of audio (in my case all stereo or all 5.1), I can select which clip becomes the default no problem, it’s only when a 5.1 clip is included in the source clips when all the others are stereo. Is there a way to select the 5.1 clip and make it the (camera 1) audio source?
Thanks in advance,
Steve

I'm guessing the marker thing is by design.
For the audio, once the sequence is created, just Mute all the stereo tracks.

`~`* Multi-Cam = DSLR sending me to LOONEY BIN!!

First off, my system properties...
quad core, 16GB RAM, GTX550Ti graphics card
Premiere CS5.5
I'm editing multi-cam....
Two camera's with diff properties -
Cam #1) 29.97fps + 1.33 PAR + 1440X1080
Cam #2) 23.97 fps + 1.0 PAR + 1920X1080 = (DSLR)
The main problem I'm having has to do with the DSLR - cam #2...seems to be making premiere go a little haywire.
The two big issues =
A) When opening project, sometimes DSLR footage shows up in the project panel....sometimes it doesn't. It just says media pending. A couple times it's said "media offline".
I have to quit premiere and start it back up and usually it pops back up...sometimes further opening/closing is required.
Initially when I imported the files into the various projects (about 13 total proj's for the series I'm producing)....the DSLR footage did not import. It just froze premiere and had to open/close...try until it worked. Some proj's the footage imported right away. Same project settings.
B) Currently, I'm rendering the video's and about 12 diff times so far, the exports either don't start when I start queue....or they do start but freeze at a given point (5%, 15%, 40% complete).
I would think this has to do with the DSLR #2 cam but that's what I want your insight on. I then close the proj out + encoder, and reopen and repeat until it works. It's worked for all with exception of one video.
Why is the DSLR giving such trouble - as listed above?
Any solutions for this?
The DSLR plays choppy as well, even when I match sequence exactly to video. But, my computer isn't taxed at all = low CPU/RAM.
Don't understand it...
All I know is it's a massive pain in the tush!
Other details...
I tried editing via the multicam monitor but the playback was so choppy I decided to just created a nested sequence and edit via timeline.
The sequence that worked best = specs matching Cam #1 (listed above)...so I went with that.
Is there a better way to setup the sequence for two diff camera's with diff properties?
Maybe...right clicking the DSLR footage - interpreting footage - assume frame rate...and maybe other settings?
Other issues that you may be able to help out with...
When you create a nested sequence and enable multi-cam - the audio waveform disappears. I tried a few things and searched around for a way to get audio waveform to reappear. Ultimately, I rendered the audio and audio wave pops back up.
But...
If I have to close project, switch to another project or the proj crashes, etc.....the rendered audio waveform disappears and I need to re-render again. Is there a way to remedy this? I just need to see the waveform without having to re-render or render at all. I only need one audio track for the two camera's.
Thanks for your help - really appreciate it.
P.S. - don't know why it's highlighting my text w/white box...tried fixing but no dice.

Thanks Fuzzy and Dave...
Dave - disk setup...
Everything is on C drive when it comes to adobe files, media cache, etc...
All the elements/media (video, images, etc..) for the project are on an external 500GB HDD.
There's def. a reason why I'm running into all these problems namely, what's below, but just need to obviously pinpoint what the source of the problem actually is...asap...
A) When opening project, sometimes DSLR footage shows up in the project panel....sometimes it doesn't. It just says media pending. A couple times it's said "media offline".
I have to quit premiere and start it back up and usually it pops back up...sometimes further opening/closing is required.

I would think this has to do with the DSLR #2 cam but that's what I want your insight on. I then close the proj out + encoder, and reopen and repeat until it works. It's worked for all with exception of one video.
Another thing I forgot to add to the above...
I'm not able to add these video's the render queue. I need to render each one by one because of the same trouble - the next video in queue after previous is finished, usually doesn't even load to begin rendering. The encoder just gets stuck.
Regarding what you said Dave =
I agree with Fuzzy - if your system can't cope with the dynamic matching, transcode your DV camera #1 clip into regular 1080p and use a matching sequence for the multicam. Beyond that, you could render proxies for everything.
My system does seem to be able to handle it b/c as I said, I have low CPU/RAM usage and I'm GPU accelerated.
In terms of playback, I get the same amount of "drag" with mixed footage in a sequence matching Cam #1 than when I match seq. to Cam #2 (DSLR). So more strangenosity! Again, my comp isn't taxed = low CPU/RAM.
You guys rec transcoding. Interpreting footage and matching to DSLR wouldn't be effective?
You think a mismatch in footage is causing all the problems I've listed? Doesn't seem to be the case.
Maybe it's the disk setup as you suggested but I wouldn't think so. Seems to be just a standard setup I've got.
Thank you - talk soon

Multi-Camera EDL to Speedgrade

Hello,
I have a multi-camera project edited using nested 4 synced cameras. I have tried to export an EDL and import into Speedgrade but I get a FPS error (where the fps are correct) and also I can't relink any media associated with the multi-camera edit in Sg.
Is this possible? Or does the EDL and Speedgrade not know how to locate the footage used in the multi-camera edit.
I am currently trying to use the Send To Sg option but wish I didn't have to because of the massive .dpx file creation and storage necessary.
This is a 4CAM 3 hour music performance so keeping data amounts down is helpful. I'm only trying to send one song at a time but still, lots of time and data for each.
thanks for any input!!

You have what consolidate the multi camera edit in only one track, export to ProRes or Cineform (for safe storage), and export too an EDL (reverse asemble:http://blogs.adobe.com/movingcolors/2013/02/21/super-easy-edl-workflow -in-speedgrade/) . Better divide the whole in small parts, it is more reliable. It should works fine.

Multi-Cam Window Won't Fully Open for Cam 1

Hey, maybe this is easy, but I've been struggling with it for several hours now and it's frustrating me. I'm using Premiere Pro CC and it's been like this since the new format was introduced. I've checked setttings, and I'm sure this is something simple, but I have yet to find it. If I grab the lower right side of the panel, it just makes it bigger with the same amount of Cam 1 visible.
Why can't I get Cam 1 to show up in this multi-cam shot?

Multi-cam

Im thinking about getting Panther with FCP HD 4.5. I was told that it does not have multi-cam (which Im used to using at school on FCP 5), but Im also told that I can do this (ora similar effect) manually. Can anyone help me out with how to do this?

IPhone footage zoomed in Multi Cam monitor

I am editing a wedding for a friend on CS6, for the first dance I used a camcorder on a tripod and my iPhone 4s. I have synced them in multi cam but when using the multi cam monitor the iPhone footage has zoomed in, how do I zoom it back out?

More specifically, based on your explanation, the camera is probably DV at 720X480, or maybe the smaller HD at 1280X720 while the iPhone is 1920X1080.
You have two basic choices. Context click on the larger footage and select "Scale to Frame Size" or better yet, click on the footage and go to the Effect Controls panel and use the Motion effect's Scale parameter to scale it down.
You may choose to scale it exactly, or you may decide to leave it a little larger if that frames the picture better. It depends on the footage. I often find that I want to focus the viewer's attention on the better part of the larger frame. I can do this better if I edit in a smaller frame. Once again, it depends on the footage as well as the distribution method.

Using Audio Sync for Multi-Cam Edits Premiere Pro CC

Hello everyone - I wanted to share some issues I've come across while using Audio to sync multiple camera angles....
For my music video shoot I have two cameras and an external recorder where I capture the audio and then edit in GarageBand or Adobe Audition. The problem I've discovered is that when I sync the clips using audio it will degrade the quality of my finalized audio clip.
Basically, something is happening to the audio clip quality once Premiere completed the synchronization process. I've rendered the video, exported the video etc... But there is still audio quality degradation.
I've compared this with Final Cut Pro X and the Audio in FCP X remains unchanged and is not altered in any way.
Has anyone else experienced this issue?

Update: I just happened happened to have a pair of ath m50s lying around.... put them on and I can see that in the multi cam sequence, I can hear only out of the left ear... once I drag and drop something to my timeline the audio's good again...
Sorry for this question... operator???
I shoot tech videos on YouTube and I edit my own videos, so I guess I am the operator & observer here...
Am shooting a tutorial...
Cam 1 - My Camcorder that shoots the phone
Cam 2 - Actually a screen recorder that records the steps on screen & audio from webcam
Audio - Blue Spark Digital recording to audacity
Now if I merge Cam 1 & Audio or Cam 2 & Audio alls fine... I can check the audio meters and everythings the same as before
But if I create a multicamera sequence then the audio output is about 20% lower (and no Premiere's not using the audio source from Cam1 or 2 here since they are too low and am 100% sure its not either of those)
I guess am messing up something but am unable to identify what..
Syncronize Point - Audio
Track Channel - 1
Sequence Preset - Automatic
Audio Sequence Settings - Camera 1
Audio Channels Preset - Automatic (or Mono since my Blue Spark records in mono)
Camera Names - Enumerate Cameras
Any Idea where am messing up?

Editing using Multi-cam option

I have to edit a show I did not shoot- 3 panasonic AF100A cameras supposedly synched TC wise, with the main camera receiving a feed the show audio board. Each camera has a different view, so I obviously want to pick and choose the best coverage to make a lean looking show a tad better. I've been told the best option is to edit in multi-camera mode. True? Using an iMac, with show files on an external HD. I imported each of the files into the project by clicking the 'private' folder for each. Then I selected them all, selected multicam option and then show in timeline. Couple of questions: do I need to sync the beginning of each clip or does the TC take care of that? It appears my main video and audio track is off a bit- should I just pull all the tracks as far to the left as possible to ensure timeline synching?
How do I view each camera at the same time, so I can compare footage?
I'm not ignorant, I just haven't used Premiere in years and I'm primarily a shooter, so any help or advice is appreciated

Audio limitation in CS6 multi-cam?

I'm trying to use stereo audio from my source files when I create a multi-cam clip (I've confirmed the source files are indeed stereo as there is different content on the left and right sides and when I bring that into a new sequence on it's own the source will use 2 audio tracks).
However, if I create a multicam clip in the media browser and bring that into a new sequence, the audio becomes mono and only refers to the left side of the source files and pans that center, making the right side unusable.
Is this a bug?

If the right channel is on A1, and the left channel is on A2, then you must open the multi-camera source sequence in a Timeline and enable A2.
Here's the part of Help I wanted you to note:
By default, Premiere Pro CS6 only enables audio channel one in the multi-camera source sequence. For multi-camera editing workflow, enable other audio tracks manually before editing the target sequence. To enable audio tracks for the multi-camera source sequence, do the following:
Open the multi-camera source sequence by selecting the multi-camera source sequence icon in the Project panel, right-click (Win) or Ctrl-click (Mac OS) the icon, and then choose Open In Timeline.
The Timeline opens. Select the audio tracks, and then enable the other audio tracks by clicking the Toggle Track Output button for each audio track you would like to monitor.
Now that your chosen audio tracks are enabled, you can close the sequence.
You should now be able to monitor both channels as you cut your multicamera source sequence.
Let us know if that worked for you.

Audio out of sync with multi-cam

Hi *,
I searched the forum with no big success. Many people seem to have the no-audio problem with multicam. My problem is different.
I enabled the multi-cam feature in CS4.1 in the preview (source) monitor. I have 2 video tracks (1 MPG, 1 AVCHD). Both appear and are in sync. Also the audio is in sync as long as the multi-cam feature is turned off. As I turn it on and play the monitor, it's totally out of sync with the video. Totally means, that it's really about 40 minutes away.
Any ideas?

Any ideas?
My only recommendation is to just not use GOP-based media. It's a bad idea at it's core and issues like this are not uncommon.

CS6 Multi-cam...multi audio?

Now I can't seem to figure this out for the life of me. Me and my friends have tried to do a 'lets play' type of video. So we have 3 different recordings of Xbox screens (done via HD-PVRs) which have 3 seperate audios. But using the multi-cam setting I can only get one of the audios to play or all 3 at the same time so it sounds like a mess.
How do I get it (if there's a way) to play the correct audio to the video currently being shown? I have gone into the sequence and toggled the track output on all 3 audios. Ticked and unticked the 'audio follows video' option inside the multi-cam screen, but to no avail?
I'm not sure if I'm just missing something or that it can't be done. Any help will be appriciated.

I've been a longtime Premiere user, but hadn't needed to delve deeper into Multicam sequences until a project I started today. I spent all morning and ran into the same limitation you described. Now that I've discovered a solution, I've been posting replies to all the threads that have had this issue, so someone searching for the solution like I did this morning may see it too!
Using screenshots and putting text together using Photoshop, you can view my workaround here:
The first step is creating your Multi-Cam sequence properly:
https://dl.dropbox.com/u/38225717/Multi-camCS6_1.png
The second step is duplicating the multi-cam sequence's audio onto separate tracks, then enabling Multi-Camera on the audio. You then switch each audio to the corresponding track number.
Hopefully that makes more sense in the image:
https://dl.dropbox.com/u/38225717/Multi-camCS6_2.png
It's not perfect by any means, and it's a little messy, but it'll get the job done. For me, it was a necessity as I am cutting scenes and may need to mute the boom track, adjust levels on a lav track, etc.
I hope my diagrams make sense; I sorta cobbled them together quick because I really wanted to share it with the Adobe community before heading back to work!
