I'm attempting to consolidate and transcode a sequence in the Project Manager. Parameters selected are Prroes LT (match source) and the default Exclude unused clips, 60 frame handles. I press go and invariably get the error window "An unknown error occured during the Project Manager operation. Please save and retry." None of my troubleshooting has gotten different results.
FYI, before the error window, a "Some clilps have frame sizes, frame rates, field types, color spaces and/or aspect rations differing form the selected preset. These clips will be copied in their original format to the resulting project" window.
Did you try to do the following when using the Project Manager :
DoNOTinclude Audio Conformed Files
DoNOTinclude Preview Files
Remove special characters in your media filenames
Move your sequence to a new fresh project
People which have problems with Project Manager sometimes maange to make it working by doing on of the previous things I mentionned.
As you are working with ProRes files, you could be interested to trim your files without re-encoding (so your files would stay as ProRes, with the exact same quality and keep the files metadata). There is a 3rd Party paying plugin called "PlumePack" that we develop at Autokroma which is a "Project Manager" like but with this "Trimming" feature. It often works better than the Project Manager also (for example with Merged Clips, AEgraphics, AE comps, ..) and there is a full detailled report about what PlumePack did to the project. It also works with R3D, BRAW, H264, H265, Cineform, ... More infos here : https://www.autokroma.com/PlumePack
