Proxy Media Codec

What is "apco"? My understanding of the import and transcode process is that you have a choice of Optimized or Proxy media, both of which should be ProRes 422. When I look at the Proxy .mov file info it says the Codec is "apco, Linear PCM, Timecode".
Also, what is a reasonable speed for the transcoding process? I'm using a MacBookPro with a 2.53 GHz Intel Core 2 Duo processor. It took more than 3 hours to import and transcode about 13.5 GB of Canon 5D II .mov files inot Proxy files.
Thanks

Hi Tom
Thanks for the reply. I saw "apco" when I selected the .mov and clicked "more info" file using Finder and looking in the hard drive. But, yes, when I used the Movie Inspector in QuickTime it did come up as Pro Res 422.
My MacBook Pro is about 4 years old. I don't think my graphics card is so great anymore. I think my laptop has 2. One for "Better Battery Life" and one for "Higher Perfrormance". I was told by a tech who is also using this same laptop that the "HP" cards were junk when they were new and not to bother using it. I was having issues with my Cine Display when I tried it.
I'm back to using OS 10.6.8. after having tried Mountain Lion and having all kinds of problems, particularly with Capture One Pro.

Getting my head around editing in h.264, Proxy Media, or Optimized Media for Canon DSLR

I'm trying to understand these different workflows, how they work, plusses and minues of each, with a focus on how it relates to file size. Please help me fill in the gaps
Here's what I think I know now.
Optmize meda to ProRes 422
Better for performance, but creates HUGE files. On 30 GB worth of h.264 footage, the optimzed files were over 100 GB, not including any render files, etc. I'm running off a laptop and only use external drives for storage, so I'd like to find a better way that uses less disk space and requires less time to convert (took all night for those 100 GB)
Proxy Media
Creates an easy to edit file that is very poor resolution and quality. You can use this for editing, then before final export, switch back to original/optimized media and it will re-render and reconnect with the good media.
QUESTION: If I ONLY do the Proxy optimization, do I need to also Optimize to ProRes 422 at some point also, or can I just have it refer to the h.264 .mov files and get equivalent results? If I can, this seems like a good compromize.
Editing directly with the h.264 footage
I have read that some people are dropping the footage directly into the timeline and editing without any real problems. Others say it will cause performance issues and to always optimize. Ideally I'd like to do this way as it is the quickest (no conversion) and has the smallest file sizes of all of them.
It would also be useful to start out this way and optimize later if I need to on the smaller sub-set of the footage. But I have found no good way to do a rough cut with little editing and then select only those clips used in the timeline for optimization in case I start experiencing slowdowns. Yes, you can clip-by-clip select them and "show in event browser," but you can't do this with multiple clips as far as I can tell.
So what are your workflow tips for keeping file size down? What am I missing in my understanding of these options?
I'm on a 2010 MBP i7 (dual core) with a 7200 RPM drive for what it's worth since I know the h.264 one largely depends on the hardware.

Proxy Media
If I ONLY do the Proxy optimization, do I need to also Optimize to ProRes 422 at some point also ...
Nope. You don't need to do the "Optimze Media" at all, you can use with the Proxy media for your working edit, then switch the references back to the Original media for mastering/export.
... or can I just have it refer to the h.264 .mov files and get equivalent results? If I can, this seems like a good compromize.
Exactly. And yes it is, an excellent compromise. Start working with the original media right away, but have FCPX create proxies in the background (which it switches to using as soon as each one becomes ready); if at any point you need to check a clip in place in the timeline in full resolution then you can just quickly toggle your general playback preference to "Use original", otherwise just edit away with the proxies and then switch that preference back to "Use original" when you are ready to output.
Editing directly with the h.264 footage
I have read that some people are dropping the footage directly into the timeline and editing without any real problems. Others say it will cause performance issues and to always optimize.
Yep, you can edit just with the original media if you choose but your source footage is H264, a dreadful edit codec by any measure, and certainly you will get much better timeline performance if you work with transcoded Optimized or Proxy media instead.

Proxy-media vs optimized media

Hi Folks,
Upon importing my media I'm able to choose between proxy and optimized media. The difference between and the sense of those is understood. But what I'm not understand - why I'm allowed to select proxy-media AND optimized media at the same time? In my opinion you need EITHER proxy (on a laptop) OR optimized media but never both of them together...
Because if you import as proxy AND optimized, FCPX will take the proxy for editing and the optimized files are useless, right?
So why is that, why can I choose both and not one of them?
Best regards
Jörg

You only need optimized media if your computer has problems working with the original media. Optimized media will transcode your original media to Prores 422, which is much easier CPU-wise to edit with as compared to H264. However, it takes up LOTS of space, so if you have no problems editing with your original media, you don't need to generate optimized.
Proxy media is a low-res version of your original media -- 1/4 resolution I believe, and it uses a reduced quality codec meant only for "offline" editing. e.g., using a laptop. However, like Tom says, if your machine is underpowered and you don't have the space for the optimized media, it's another alternative.
I would not recommend only using proxy media for editing since the resolution is much lower and you won't really be seeing a true representation of your content. I'd say though if your computer can handle editing in H264, there would be no reason for generating optimized media.

ITunes crashes on start up since installed Ace Media CodecS pack

First post and if truth to be told iv never had to use the support forums at Apple before because everything normally goes swimmingly well. But now im in dire need of assistance
Basically, I did one of the most silliest things I could have done and in an effort to get Audio to play on a .avi file I downloaded 'Ace MegaCodecS'
Looking in the installation file I just selected everything and whilst some programs failed to work - a quick uninstall of it seemed to do the trick.
But itunes has posed a problem somewhat.
Initially I couldnt install it or uninstall it. I even had the same 'fatal error' on Quicktime. But after using Windows Install Clean Up I managed to install Quicktime first and then iTunes.
But still the problem persists... I try and load up itunes and it comes back with an error and if I try and load of Quicktime? It comes back with a 'Buffer Overrun detected'
This is the error message for iTunes:
*Faulting application itunes.exe, version 7.3.2.6, faulting module unknown, version 0.0.0.0, fault address 0x000a0164.*
*For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.*
In addition to the above I have also used a registry cleaner to clear out any rogue items and iv also uninstalled some codecs which didnt disappear when I uninstalled the Ace Media CodecS Pack.
I love using iTunes, I keep all my music on there and because of doing this, I believe I have lost my statistical data but thats neither here nor there...I would love to get it back without having to format my hard drive from scratch.
If anyone could take the time to help me I would be ever so grateful

Proxy Media: Transcode Source File and Export Read File...

Hello, I'm new to FCPX. I have a Panasonic HC-X920. When I shoot things I copy the entire folder tree to my hard drive and import from there, rather than directly from the SD card.
I learned that FCPX "re-wraps" the truly original h.264 MTS files to "Original" h.264 MOV files. Not a huge deal, as there doesn't appear to be quality loss, and the MB/s rate is slightly higher on the MOVs. Ideally I'd be able to use the MTS files but FCP is Quicktime-based and I've decided I'm not worried about it.
Anyway,
My computer can't handle playing back 1080p 60fps h.264 footage. In order to have playback on an FCPX timeline, I have to transcode to either Proxy or Optimized media. Optimized, of course, takes up a ton of space, so I'm curious about using Proxy. But I want more info first.
I'm most curious about question #1, but here are two questions:
1.
Let's say I transcode everything to Proxy Media upon import. When I go to share/export a final file from my timeline, which of the following does FCPX do?
(A) Export the timeline using/reading from the lower-quality Proxy media, ignoring the Originals.
(B) Automatically replace the Proxy media with the Original media files, and export the timeline using/reading the Original media files while ignoring the Proxies.
(And if B is the answer, is it reading the Original MTS or Original MOV? I'd assume MOV, right?)
Does this question make sense?
I'll mostly be editing home movies with this, so it's not imperative that I be able to see what I'm editing in vivid detail and I can use Proxy for that to save disk space. But I DON'T want my final exports to be based on that lower-quality transcoded 422 Proxy Media; I want the proxies to be view-only, and I want the final exported quality to be based on the quality of the Original media.
My other question:
2. (probably not a big deal either way)
When FCPX transcodes to Proxy and/or Optimized, is it reading from (A) the "Original" MOV files it created upon import, or (B) from the "truly original" MTS files?
Thanks!

Tom Wolsky, thanks for your answer.
1. Where do I switch playback to original, in the Preferences? I'm attaching what I see in my Playback preference window. I don't see a place to switch this, am I doing something wrong?
2. That's what I suspected, thanks for clarifying.
Here's the screenshot I mentioned in #1:

Use of proxy media in viewing, then exporting projects from FCPx

I am trying to get my head around the use of proxy media in FCPx and would appreciate feedback
Up till now, having used H.264 files from various cameras, I have not had the need to use proxy files. I get smooth playback etc, no issues. Now, however, using the Blackmagic Pocket CC, and find that when I am 'on the run' and using a USB external drive, or even a firewire 800 drive, it struggles to playback the very large Prores files.
I understand the use of proxy media files in playback, and to assist with smooth editing.
Where I am lost is in how to ensure that any exported files from FPCx, either directly (or if I send to Compressor) are using the high quality Prores files, and not exporting based on the proxy files
I see well, how to change the file for playback from prores to proxy and back, but how do I ensure the high quality file is used for export ?
Best Wishes
Paul

The playback switch berween proxy/originals also switches what is to be used when sharing.
When switching to originals and requesting to share the switch is locked until the sharing process completes (so you can continue editing, but using originals only).
Not sure if this affects Compressor. I believe not.

How can I set which projects use Proxy Media and not just change every project?

Hi there
I can see how to change ALL projects to use Proxy Media or Original/Optimised Media
in
Preferences>Playback
But I'm switching between projects a lot and I only want to use Proxy Media on one project, so how can I tell FCPX to only use Proxy Media on that ONE project?
Thanks

Perhaps if apple didn't take back prores LT this wouldn't be as much of an issue.
Pores LT was a great compromise between file size and quality. It produced a fine image for most peoples needs and was 30% smaller.
Hopefully it will be returned soon. I can't imagine why it's not already there. Unless they want to charge for it, ... again..
Have you tried capturing as full res, then change prefs back to proxy, open a new project and import the full res files?
In FCP7 the render pref was separate from the capture pref. is that gone too?
If my idea doesn't work, Surely someone will chime in with a creative work around to this.
And hopefully it'll get fixed soon in an update.
Best,

"AVCHD" gets choppy when I try to edit in "FCPX" ... should I import and optimize video or create a proxy media???

So I'm shooting some video on a Sony CX430
60fps & 24fps
Both on AVCHD format.
And working out of my MacBookPro
Processor 2.8Ghz (intel core 2 duo)
Mem 8GB 1067 MHz ddr3
1TB hard drive Space (440GB actual free space right now)
im having trouble editing the video. the video becomes choppy and seems to drop frames. its no where near as smooth as when i play it back on the camera itself.
1. should I be transcoding the files as I import them. ?
2. And if so, which option.
I. Create optimize media. Or
II. Crete proxy Media ?
once I have played and done some editing in FCP.X
3. Do I need to buy and use a compressor to get them burned on to a Blu Ray or DVD. ?
4. What is a good Blu Ray burner (external) I should use/buy?

#1 on my completely under powered MacMini, 2.26GHz/8GB, I'm noticing, it's faster to make the import/conversion a two-step process: step1 import, step2 after import select all clips, cmd-click, convert. If you import 'over night', I wouldn't care anyhow.....
#2 for stutter free edit, I prefer Proxies; … Optimize is only recommended when you use a seperate, ext. hard-drive, due to sheer amount of data (~220GBs/h)
#3 FCPX allows creation of DVD/BluRays - but: very simple ones, to be exact: two 'designs', just one Project, no fancy menus etc. 'Disk' isn't Apple's preferred delivery format for many years …
#4 I'm not burning disks; LG and Samsung seem to have a good track-record ...

Best way to delete transcoded and proxy media?

Hello,
I am trying to free up some disc space and am curious what is the best way to delete transcoded and proxy media in fcpx? I know I can open up a library bundle and delete the folder, but is this safe? There must be a better option...
Thanks,
Austin

I don't know of any other way.
Proxy and Transcoded media can always be re-generated if the original files are in place.
If this question refers to your system drive then a BIG suggestion is to aquire a fast dedicated media drive.

Why can't I use proxy media?

I've got media from 3 cameras - all are 720x480. Two were imported from camcorrders, one was miniDV and one was JVC hard drive (SD). When importing I did not have the option to create proxy media, and still do not have that option available (it is grayed out). The third was imported from an avi file uncompressed; it created proxy media when importing. I am trying to use them in a multi-cam clip. If I use proxy media, the two clips from the cameras show the red/yellow "Missing proxy" screen but the avi file shows fine. If I select "use original or optimized media" the clip from avi drops frames, either with "better performance" or "high quality" settings. I know I've had it playing back OK before, but don't know what I have changed such that I can't get a good playback in the multicam multi-angle viewer. It seems if the camera video is already coded so it doesn't need proxy media, it should use that format when proxy is selected (I'll make that suggestion on the feedback from). Any help would be appreciated.

The problem is AVI is not a native format to FCPX while DV is. And FCP X will not make DV into Proxy for this reason. So if you want to mix AVI with DV you need to do it in 'original' mode. For better performance what you'd want to do is convert all of the AVI to a better format- like ProRes for example then import that as your new originals for mixing with the DV footage.

HOW do you use "com.sun.media.codec.video.jpeg.NativeEncoder"???

Hi!! I want to know if I can use this encoder (NativeEncoder) for encoding to MJPG.
If I do: PlugInManager.getPlugInList(new VideoFormat( VideoFormat.RGB),
new VideoFormat(VideoFormat.MJPG), PlugInManager.CODEC);
I obtain only one codec:com.sun.media.codec.video.jpeg.NativeEncoder
BUT, then, I do: codec.setInputFormat(new VideoFormat( VideoFormat.RGB))-->It returns me:NULL. why????!!!
Regards!

The input format may have to be more specific and suitable; eg for Windows :-
RGBFormat(new Dimension(w,h), w*h*3, Format.byteArray, -1.0F, 24, 3, 2, 1, 3, w*3,-1,-1)

Color Correction Using Proxy Media

If you color correct using the Proxy Media settings, are the changes you've made still going to be applied to the video when you switch back over to "Original Media?"

Yes.

Bad audio when using proxy media

I'm using FCPX on my MBP 15" late 2008. To get some reasonable speed I transcode all the clips to proxy media.
Doing this degrades audio quality to a point where the audio makes a clicking noise all the time.
Also when I add a sound effect and edit it in surround with keyframe animation the sound makes clicking noise all the time.
This noise is present when I export the movie.
What to do?

Trying that now
The odd thing is that the audio is fine when I play using optimized/original media. The audio gets crappy when I switch to proxy media.
I also get sort of the same problem when I'm using sound effects and choose "Create Space" or "Circle" under Audio inspector. These sound effects should be in the correct format since they came with FCPX.

Where is the proxy media

When I import my footage a choose to create proxy media. However when I create a munticam project and change preferences to use proxy media it says its missing. I've got to be doing something wrong!!

AndyOllery,
You have a couple of choices concerning proxy media when you import your footage. Make sure you have actually created those files. See Transcode Media Files for detailed information.
To directly answer your question, your proxy files will live in ~/Movies/Final Cut Events/EVENT NAME/Transcoded Media/Proxy Media folder. (~/Movies assumes you are using your localstartup drive)
If you don't see the files in there, niether will FCPX. If you don't see them there, then use the steps in the above link to make them now.
Best of Luck!

Shouldn't happen.Only thing I can think of suggesting is to delete render files and try again. Trashing preferences is a long shot, but no harm in trying. Use the Digital Rebellion Preference Manager, a free download.
Assume you have a reason for using such an outdated version of FCP X. That may be contributing to your problem.
