Suppose you have some RAW footage, in CinemaDNG format (a number-sequenced set of [.dng] files), for example shot on a Blackmagic Cinema Camera (BMCC). Compared to “visually lossless” say ProRes or DNxHD (let alone H264 etc.), CinemaDNG occupies an awful lot of disk space, primarily because it is mathematically lossless. The GoPro-CineformRAW encoding format offers significant reductions in file size (and hence data rate) at the cost of a practically negligible loss of visual information (and a purchase price). This codec can be purchased as part of the GoPro Studio Premium product. A comparison-grid of the various GoPro Studio products is here.
CineformRAW is an attractive compression-format, but unless care is applied to some very technical-level encoding options/settings, compatibility problems can arise when importing to DaVinci Resolve. The latter is in widespread use but is especially relevant to BMCC owners because it is supplied as free software with that camera. I experienced such problems myself: one version of Resolve (v.10.0) interpreted CineformRAW clips as green-tinted, while another (v.10.1) just gave black frames.
Happily, a simple solution existed: RAW4Pro, which is essentially a front-end to CineformRAW (and also to DNxHD, useful e.g. if you want HD proxies).
Summary:
- Install
- A product incorporating the GoPro-Cineform RAW codec.
- The RAW4Pro utility
- Essentially a front-end to generate CineformRAW and also to generate HD (e.g. as proxies) as DNxHD, in each case in either MOV or AVI container-formats.
- Run RAW4Pro
- Select (Browse-to) input-folder, output folder.
- Select:
- Sound: Audio-Merge
- Initially, extract audio from source file to a WAV file, then merge this audio in with the generated file. The WAV file remains, regardless.
- The alternative (if not enabled) is no audio in the generated file (and no WAV file).
- Processing: Convert-Only
- Quality: Fine
- Clicking the [?] button reveals that this creates 10-bit Log (colour-channel resolution).
- Video Format:
- Cineform RAW (encoding format)
- MOV (container format)
- LUT: NoneClick the [Process Clip] button.
- Result:
- A movie file with name prefixed by :R4P_” and suffixed by “_sound”, incorporating both video (10-bit Log) and audio tracks.
- An audio WAV file, similarly prefixed, generated as a “side effect”, may or may not be useful to you, can be deleted.

Seems a little pricey, but worthwhile in my case because it addresses two requirements that have been nagging me (before I discovered that product):
- Has intelligent compressor, maximizing loudness and minimising dependence on manual tweaking (eqials time in post).
- Has good-quality reverb.
It’s a plugin (DirectX /DLL), no standalone application. Hosts / plugin formats:
- The manual refers (Page 119) to <<Pro Tools, VST, AU and MAS versions of Ozone … (and) DirectX version>>
- The website
- Plug-in formats:
- Pro Tools 7.4+ (RTAS/AudioSuite), VST, MAS, Audio Unit, DirectX
- Plug-in host compatibility:
- Pro Tools, Cubase, Nuendo, WaveLab, GarageBand, Logic, Audition, SONAR, ACID, REAPER, Sound Forge, Peak, Ableton Live, and many more
- Does not mention:
- Sony Vegas (even though I found it works in this)
- Adobe CS5.5 Production Suite e.g. Premiere. Can it work with this and its siblings?

I have a Sony XDCAM-EX clip at 1280x720p25 to be transcoded to ProRes, so it can be used as source for iMovie (for another user on another machine).
In principle it should be very simple: go on Mac, use Compressor to transcode the XDCAM footage to ProRes. But as usual, things are pernickety…
Sequence:
- First tried dragging the XDCAM [.mp4] file into compressor.
- Not recognised.
- Likewise the BPAV folder.
- Next, I transcoded the XDCAM footage to “MXF for NLEs” format, using the Mac version of Sony Clip Browser
- Next, opened the XDCAM Transfer app.
- In this app, open the XDCAM’s BPAV folder.
- The footage displays OK but how do I export it to a QuickTime [MOV] file?
- Looks like I can’t. It only offers to export to an [MP4] file.
- Instead, I guess I’ll have to open it from FCP.
- FCP
- I opened a random existing FCP project.
- The footage is 720p but the project/sequence settings are arbitrary (unknown to me)
- FCP: File > Import > Sony XDCAM…
- It imported to somewhere … but where?
- FCP Browser: file > RightClick > Reveal in Finder
- It was at [/Volumes/GRm HFS+/_Media/_Projects/2010-05-30 (Esp) Alison Doggies/020 Source/Sony XDCAM Transfer/SxS_01]
- File System:
- In other words, at whatever destination was last used by some app – presumably XDCAM Transfer or possibly FCP
- The destination path was in fact specified in XDCAM Transfer, under its Menu: [XDCAM Transfer > Preferences > Import]
- Moved the file instead to [/Volumes/GRm HFS+/_Media/_Projects/2009-11-22 (JRM) Lady of the Silver Wheel]
- Compressor:
- Open it in Compressor
- Drag it to the “job-strip” (my term) in Compresor.
- Compressor displays data about that clip (e.g. 1280×720, 25 fps)
- Select jobstrip settings:
- Select Setting
- Settings: Apple > Formats > QuickTime > Apple Pro
- Name: Apple ProRes 422
- Description: Apple ProRes 422 with audio pass-through. Settings based off the source resolution and frame rate
- Apply (Drag) Setting to Jobstrip
- Destination
- Leave destination unspecified. Then it will be the same folder as Source.
- Processing (transcoding) of this footage (1280x720p25) took about 3 minutes (on MacBook Pro 2009).
- Result was not that much bigger than the original:
- Originally recorded [.MP4] file: 1.19 GB
- Rewrapped [.MOV] from XDCAM Transfer: 1.14 GB
- ProRes [.MOV] from Compressor: 1.97 GB

- DON’T:
- Don’t edit HD footage on a SD timeline.
- Pasting into an SD timeline is the worst thing you can do. FCP is terrible at conversion of HD to SD. At the very least send your HD Quicktime movie of the timeline to Compressor and have Compressor make the conversion.
- A much MUCH better way would be to invest in something like an AJA Kona board which does full broadcast conversions in realtime.
- Don’t ever down-convert HD to SD before encoding to MPEG2. It’s not only completely unnecessary waste of your time, it’s an unnecessary re-compression step that will make your DVD hideous.
- Don’t “Export using Compressor” directly from the timeline.
- you can keep editing in FCP while Compressor encodes
- Compressor is faster when working from a single file, because it avoids the look ahead clip by clip encoding features of VBR encoding that pretty much creates more problems than it solves.
- DO:
- File > Export > Quicktime Movie.
- Leave it set to “Current Settings”
- You can export a Reference movie if you’d like, meaning leave “Make Self Contained Movie” UNchecked.
- Take that Quicktime movie into Compressor.
- Choose the DVD Compression of your choice, such as DVD 90 Minutes High Quality.
- Compressor will create a Standard Definition 16:9 MPEG-2.
- Also select the Dolby Digital Audio to create the AC-3 audio file.
- Launch DVD Studio Pro and bring the MPEG-2 and AC-3 into your project.
- Now create a DVD!
- DVD Studio Pro will create a DVD in 16:9 widescreen format that will automatically play Letterboxed on a 4:3 TV and full screen on a 16:9 widescreen.

On MBP, I tried starting-up Compressor but its icon just bounced up & down (on the task-bar) for ages. Attempts to right-click it revealed a “Not Responding” condition. So I searched for a solution. I discovered a check-list Compressor: Troubleshooting basics at http://support.apple.com/kb/TS1888?viewlocale=en_US. From that check-list, the fix that worked was to delete my account’s Preferences for Compressor, as follows:
- In the Finder, go to ~/Library/Preferences
- (where the tilde (~) represents your Home folder).
- Remove the following files from the Preferences folder:
- com.apple.Compressor.CompressorSharedService.plist
- com.apple.compressor.Compressor.plist
I discovered the checklist at http://discussions.apple.com/thread.jspa?threadID=1408723, which also gave some more tips.

- iMovie rough-cut to XML to FCP to QT (reference) to Compressor
http://www.youtube.com/watch?v=oTrxEAPGY5Y
- ScreenFlow for screen captures
- e.g. 5 minutes exported as ProRes 422 gives 10GB
- iMovie:
- Rough edit in iMovie
- Trims, cuts and AutoAdjust (for levels)
- Share > Export Final Cut XML
- Final Cut:
- Refined cuts, transitions etc. and add soundtrack
- e.g. Soundtrack Pro (STP), find music etc from library, reveal in Finder and just drag to FCP project, no obligation to make an “official” STP project.
- Export to QuickTime – uncheck the “Make self-contained” option if only to be used on same system (e.g. to send to compressor for render-on to some other format).

As a first experiment (with how well or not FCS3 would run), I installed the upgrade to a new machine.
Groundless concerns:
- There is no hassle over installing it on a second machine. The license allows it and there is no Deactivation etc required. Only if both machines are on the same network will it complain.
- It was not necessary for the target machine to have the previous version of FCS installed.
The update physical form was a cardboard box measuring about (by eye) 5x5x1.5 inches. Its main contents were 7 data-DVDs, a nice concise booklet and some formal documentation, one of which had the serial number printed (twice). Installing the system took a few hours.
The main installation disk additionallycontained electronic documentation. I copied it to :
- Boris Calligraphy User guide
- Exploring Final Cut Pro 7
- Same as the booklet that came in the box.
It also contained “Extras”, as follows:
- AppleQmasterNode.mpkg
- Allows a computer to act as a node in a render-farm, in support of Compressor. If you are unsure which role each computer will play in your network, just install the Apple Qmaster software on each computer in your network. You can sort out the details later. [http://documentation.apple.com/en/appleqmaster/distributedprocessingsetupguide/index.html#chapter=2%26section=2%26tasks=true]
- I started its installer but it asked whether I wanted to let this computer be used as a rendering node. I had already been asked that question when loading the main FCS3. So maybe it was loaded already. Decided that FCS was probably best left alone in this respect, so I aborted the install.
- CORRECT: While following QMaster tutorial [http://www.youtube.com/watch?v=oTrxEAPGY5Y] I checked existing System Preferences for QMaster and they were already there, it was already enabled for sharing.
- In contrast, when I checked the same for my older machine running FCP6, its QMaster was not enabled for sharing. Of course I fixed that immediately.
-
- BUT in both cases (both machines) the options were greyed-out.
- For the newly-installed FCP7 machine, Options for selected service (Compressor) said “Selected Service On (2 instances). Sounds like it’s using both cores OK.
- For the older FCP6 machine, it said “Selected service On (1 instance)”. But its an 8-core machine. So maybe something is not quite right…
- Then again it might be a “feature” of no significance, just run a render and check Activity Monitor to see if all cores are being used [http://discussions.apple.com/thread.jspa?messageID=7315551]. The discussion (like some others) also suggests not using all the cores available.
- DVX-100 Audio Sync Tool
- DVX-100 is a camcorder by Panasonic. Broadly EX3-like and film-ish e.g. 24P)
- I don’t need this, so I won’t install it.
- Head Leaders for Cinema Tools
- Countdown etc.
- A number of prebuilt QuickTime clips have been included to use as head leader in your edited sequences. Using these head leader clips is preferable to selecting the “Start with 8 seconds of leader” checkbox in the Export Film Lists dialog because these clips also contain Picture Start, countdown, and an audio pop at the 2-second mark. [‘Head Leaders Read Me’ file]
- I guess they’re intended to be copied somewhere (?). I put them at […/Documents/Final Cut/FCS 07]
- Spotlight Importer
- Spotlight importers should be provided by all applications that support custom document formats. A Spotlight importer parses your document format for relevant information and assigning that information to the appropriate metadata keys. [http://developer.apple.com/mac/library/DOCUMENTATION/Carbon/Conceptual/MDImporters/Concepts/WritingAnImp.html]
- In other words, it allows Spotlight to search withinapplication-specific files.
- But when I tried installing it, it said “The domain/default pair of (com.apple.dock, loc) does not exist”. Don’t know what it means but it sounds broken… Either way, I can’t install it, so must abandon it.
- Template Intro Movies for DVD Studio Pro
- Blocks, corporate, mosaic, stripes, smoke…
- I guess they’re intended to be copied somewhere (?). I put them at […/Documents/Final Cut/FCS 07]

Eugenia recommended ([http://eugenia.gnomefiles.org/2008/09/15/prores-for-windows/] as of September 2008) DNxHD and ProRes, among other codecs, for transfer between PC and Mac. She also advises Lagarith for transfer to/from linux, though it sounds slightly tricky.According to BobRusso (Applications Specialist at Avid) [http://community.avid.com/forums/p/62217/407573.aspx#407573]:<<<
You can install the ProRes decoder on a system without FCP:
Make sure you have the latest version of the Avid codecs. They can be downloaded here:
I suggest using MPEG Streamclip to convert the files: http://www.squared5.com

Gleaned from Philip Bloom’s presentation on using a 30p native cam to produce to other standards (e.g. 24p):
- Edit native, convert the edit result, not the source (rushes). Saves render time (& space)
- Don’t edit H264 – current machines are not fast enough to avoid jerkiness.
- Before edit, convert to ProRes (standard is sufficient, no need for HQ). If disk space at a premium then could instead use XDCAM EX format but that is not compatible with Cinema Tools.
- Conversion to ProRes is done twice as fast by Mpeg StreamClip (free) than by Compressor.
- Mpeg StreamClip:
- [File > Open Files, File> Export to QuickTime, choose format ProRes 422, change top-slider to Full 100% Quality (default is less)
- Can also use it to batch-convert, result can be either separate files or all concatenated in sequence.
- (DO THE EDIT)
- FrameRate Conversion:
- Simplest: speed change – change the timebase (the rate at which the existing frames are presented). OK when speed change does not matter (e.g. static scene).
- Can be done e.g. via Cinema Tools.
- Stages: Analysis then select desired new framerate then Conform.
- (or [Cinema Tools: File > Batch Conform], select a folder containing set of files, select any example file in it, Open, change speed, go: all the files are done)
- Speed-preserving frameRate conversion can be done by Compressor or by JES Deinterlacer (free)
- Compressor
- Open Compressor
- Drag file to job-strip
- Create a Setting if needed
- Geometry (5th icon along) – set Frame Size to “100% of source” (to ensure Compressor setting doesn’t re-scale)
- Frame Controls: Unlock
- (ignore settings that don’t apply e.g. resize method)
- Rate Conversion: choose the fastest you can get away with
- It is not compulsory to set a Destination.
- (what happens if not? same directory as source? what filename gets generated)
- If no destination specified then file goes to same directory, auto-named as the original filename plus the name of the export format Setting. Example: From TRV 12-39 AvidGrade.mov it generated TRV 12-39 AvidGrade-QT ProRes Interlaced.mov, where QT ProRes Interlaced was a compression setting (previously defined by myself). Incidentally the QT-DV was 35MB, the generated QT-ProRes was 47MB.
- JES Deinterlacer
- Choose > (input your file)
- Output > Compressor > Export
- (nothing to do with Apple’s Compressor, at least I assume…)

Context:
- In a Compressor job I defined a file on an NTFS drive as source. That was because I had a file of graded video on that drive which was being used in a Sony Vegas project and I wanted to use FCP’s excellent SmoothCam effect to de-shake that video. For that Compressor job I defined a destination on a separate drive that was HFS+ hence read/writable by Compressor.
Problem:
- Compressor gave an error to the effect that the source drive was not writable hence not a valid destination. Even though it wasn’t the destination…
Interpretation:
Response:
- Workaround: copy the source media file from NTFS drive to HFS+ drive and use that as source instead, no other change. Worked fine (apart from wasting my time and disk space).
