Hey all, long time lurker, first time poster…
Travis – What version of MC are you using? I have been using MC since ~6.5 and never ran into this problem. I am currently working in a project using v 8.7.0 using 2K prores with source TC and my imported media has maintained that source TC.
I noticed in the screenshot you referenced the version in question was MC v 2.5.3 which was quite a while ago and very well could have been a problem back then.
I’ve never had to merge bins, so if you take this approach I’d be very curious to hear how that process works out for you.
Here’s a thought that should work, and I just tested it on my machine. Try a batch re-import. I knew the stipulation with batch re-import is the file needs to be the exact same length as the clip that is being replaced in media composer, but I was curious to see if it needed the same TC as well (test results it doesnt’).
I took one file “A006C007_160919_R0J1” from my project, put it in a timeline and exported it to prores with the same name. Since it was exported from a timeline that clip’s source timecode now starts at 0. I jumped back into MC, found the file, and just to make sure it really worked, I deleted the master clip’s media from the 1 folder. I then right clicked, selected batch re-import, and set the file destination to where I exported my new prores A006C007_160919_R0J1 file (the one with TC starting at 0). selected that, and MC re-imported it, with no problems.
Sorry if this is long winded, but after that test I think you can 1. back up your media folder and project so you don’t lose anything and then 2. try and batch re-import using your prores files, and I think it should link up exactly the way you want it to. And then there’s no over cutting!
Let us know how it goes!
