  • Media Composer on Apple Silicon Moving Forward

    Longtome user, rare poster.

    I'm looking to move to a Mac Studio after I finish my current project.  I'm on a 2009 cheesegrater that I've upgraded a lot over the years,  My 4k broadcast documentary and corporate projects have measured delivery times so long rendertimes have not been a problem for me, but it's time to upgrade.  As soon as the latest Mac OS is qualified, I'm going to make a move.  I'm excited to try the new interface, and all of the new features that keep bubbling up.  As part of my research, I ran accross this video on youtube. https://youtu.be/SjQ7A1INxHE  It's long and pedantic, but offers a lot of keen insite on running media composer on a mac without quicktime, which is one of the reasons I've coddled my old system for so long.  For those wanting to run Media Composer on the Mac, I think it's a good watch.


  • 2019 mac pro and Nitris?

    Hey all, I just purchased my new 2019 Mac Pro... I was simply going to swap my Nitris DX pci board into it and move forward, but apparently, Avid has discontinued drivers for it past Mojave? And the 2019 isn't qualified for Mojave...

    So what is a Nitris user to do??? 

    I have a 16 channel Mackie, proper studio monitors, and a large SDI colour grading monitor to hook up. 

    Take away the uselessness of the Nitris as hardware acceleration it is still an amazing break-out-box for professional editors that run full suites, not just soft suites.

  • Appropriate Avid Transcode and Export for these UHD raw files? (Raw file specs: .Mov, 4:2:0 8-bit, H.264 100Mbps)


    My goal is to be able to create a 30 minute video with the following specs:

    .MP4, H.264, UHD (3840x2160), 23.976fps 

    and get it to be a "reasonably" smaller file than the total 31 GB of raw footage.

    I mainly wondering, can anyone suggest a better (more efficient) transcode codec to use for my raw footage, and is there a quicker (more effiicient) way to get to the final H.264, .MP4 file? I'm also totally open to any recommendations for compressing my final UHD H.264, .MP4 file, if that is something I should consider.

    Much thanks!! for any help on this :)


    Here's what I ended up doing:

    1. I shot about 45 minutes of 23.976 fps footage using a UHD (3840x2160) codec with the following specs: .Mov, 4:2:0 8-bit, H.264 100Mbps. The total size of all of the 45 minute footage is almost 31 GB

    2. I made my sequence using the linked files, then transcoded the sequence (linked media with handles) to DNxHR HQ (8bit), which according to the Avid codec bitrate specs is 711 Mbps (88.88MB/s x 8bits), and has a compression ratio of 4.5:1.

    3. Exporting a final cut 30 minute sequence in DNxHR HQ gave me a total file size of 148 GB, way larger than the original 45 minute footage.

    4. I then tried exporting the final 30 minute sequence as DNxHR SQ (8bit), which according to the Avid codec bitrate specs is also 711 Mbps (88.88MB/s x 8bits), and has a compression ratio of 7:1.

    5. This gave me a 30 minute file total file size of  98 GB, still way larger than the 30GB of the 45 minutes raw footage.

    6. I then took the DNxHR SQ file and exported an H.264 .MP4 file in Adobe Media Encoder, using the Youtube suggested bitrate of 35Mbps for 2160p (UHD) files, and this file came out to 7.5 GB

  • How do I export Media Composer sequence for basic video cutting and sound editing Pro Tools Ultimate?


    I am specifically interested in being able to export a sequence with all the video clips intact and not bounced to a single long reference video, to use in Pro Tools Ultimate, so that I may work on the sound editing of course, but I also want to be able to make basic Video cutting tweaks in Pro Tools Ultimate, to shorten, lengthen and/or delete some of the video clips in the timeline where needed. I then want to be able to import the Pro Tools session back to Media Compose with the Video cuts I made in Pro Tools Ultimate.

    I have not used Pro Tools Ultimate yet, but from what I've read, I should be able to do the basic video cutting I'm interested in, but I'm not sure on how to export my Media Compose Sequence properly for use in Pro Tools Ultimate. 

    Thanks for any info on how to do this :)

  • Trim Tool Access and Beachballing

    Hi all


    Pretty much as described. Whenever I need to go into the trim mode it gives me approx. five seconds of beachballing.


    I'm on:

    Avid MC 2022.7

    Monterey 12.6

    Mac Studio - M1 Ultra 20 core

    128GB RAM


    Any advice appreciated.




  • Avid Artist Controls LCD screens are completely solid yellow, please help

    Greetings, I have the Avid Artist Color and Avid Artists Transport, but haven't used them in over a year and now when I open them up in Media Composer, the LCD screens just show complete yellow, and look like rectangles where words would normally be, as if all the LCD lights are all fully bright. Can anyone please let me know how to fix this? Much thanks :)


  • OSX 11.7.1 and Media composer 2022.7.0


    Trying to upgrade to Big Sur 11.7.1 and run media composer 2022.7.0. Is any one running this successfully. According to the documentation they only show  osx 11.6.x but looks like 11.7.1 was released after the documentation was written for this version. App store will only let me download 11.7.1, so I am trying to stay on BigSur and not go to Monterey just yet. Wondering if anyone was running these versions successfully.



  • Zoom while editing using iMac - Audio solution?

    Hi all

    I've been editing remotely for years now using Zoom to share the Avid screen and audio with directors.

    The audio has never been that satisfactory at their end. I think the audio they're getting is simply what the iMac hears coming out my speakers in the room? Dialogue often unclear and music rarely cuts through well, even with "original sound" enabled.

    Is there a simple way to send the Avid audio direct to the director and also be able to talk to them, ideally without me having to wear headphones?

    What do other people do?

    My setup is Avid  on iMac, using AJA T-Tap BOB, I also route the audio though a Soundcraft mixer.

    Thanks for any pointers!
