Greetings all.

There have been many-a-conversation about handling spanned ProRes files from DSMC2 type cameras. In fact, enough people have emailed me regarding various workflows that it lit a fire under my butt to make a useful tool. To compound issues, working with ProRes in general on Windows is often a bit no-so-fun.

I've created two new tools to make life easier when it comes to production and post production related task when dealing with ProRes on the Windows side.

First up, clipJoin:



Working with Apple ProRes on Windows based workstations is sometimes tricky. Some modern digital cinema cameras have the capability to record with the ProRes codec directly in camera. However, this often creates segmented or spanned .mov files in 4GB chunks due to FAT32 restrictions and not just one large file. Importing and reassembly takes time and re-encoding is time consuming as well.

The true solution join them in a non-lossy manner. That's the goal of clipJoin.

What clipJoin does is join spanned ProRes .mov files into a new file contain each of those clips.


How to use clipJoin:


To join selected .mov files:
- Drag and Drop one or more .mov files onto clipJoin
* You will be prompted for a filename to save it as
* Clips are joined alphabetically/numerically​


To join RED Apple ProRes spanned clips:
- Drag and Drop any .RDC or .RDM folder(s) onto clipJoin
- Drag and Drop any folder containing .RDM(s)
* It is important that the mag folder structure is just like on the RED Media
example: A002_0101GS.RDM\A002_C001_0101F8.RDC
* RED ProRes .mov clips will be exported with the base filename to output path
* Yes, you can just drag and drop a mag straight onto the program
* If working on RED clips it will make mag directories in your output path​


Notes on File Saving:
* You must enter an output path for your joined clips in the:
settings_clipJoin_outputPath.txt file (in the install directory)
example: E:\export\dailies​

** Special note. If you try to edit "settings_clipJoin_outputPath.txt" and install the program in "Program Files" on Windows you will want to start notepad.exe "As Administrator" to edit and save the file.​



This supports all ProRes formats with and without audio.


Next up, movMuxer:



Commonly on set and in post houses Apple ProRes files are generated, but the audio of the file needs to be tweaked a bit. Normalizing levels, adding ambiance, removing background noise, swap vocals, etc. Tasks that are often important for dailies or deliverables. You can extract the audio from the file in a multitude of ways, but often when you add it back to your .mov file and need to re-encode.

movMux is a Windows program that extracts audio in a .wav format from a .mov file.

It can also merge a .mov video with an audio .wav file.


How to use movMuxer:


To Extract Audio (demux):
- Drag and Drop one or more .mov files onto movMux
- Drag and Drop a folder containing .mov files onto movMux.
* Extracted audio .wav files will have the suffix "_extractedAudio"​


To Merge Audio (mux):
- Drag and Drop a .mov and a .wav file that you want to join onto movMux.
* The merged .mov file will have the suffix "_updatedAudio"
* Both the .mov and .wav file must be the same exact length of time.​


How to get them?



You can purchase both here for a whopping $35 bucks.


*Side Note. Let me know if you have any thoughts or would like to see anything added.

**Double Side Note. I'm a full-time Director/Director of Photography and will do my best to support these crazy tools, but I shoot a bunch. So please be patient if anything is funky. I've tested these out on 5 boxes with Windows 7-10. They should be public-friendly at this point.

Marc, Mikael (maker of FoolControl) has already developed an app for Mac users.

Phil, this is so great! Thank you for the crazy hard work. Will give it a swirl tonight!

As Simran mentioned Mikael made a Mac based thing. My goal here was/is to provide and elegant solution for the Windows folks who are often left in difficult positions when it comes to ProRes and general management. Considering that it's supported in a few applications as native exports on the Windows side of things, it is indeed getting easier. I'm working on one more thing that will make all of this EXTREMELY easy. It's just super hard moving this boulder. But they like me at least :)

Side note. I'm going to make a quick instructional video for these tomorrow.
 
New to this forum. The answer might be above, and / or I might be posting in the wrong place. We just shot on the RED Epic Weapon and had issues with “spanned clips”. We ended up stitching longer shots together in video post production. Not fun. Do you know if they have fixed this?
Thanks!

Format the card as UDF and the quicktimes are one piece.
