Thank you, RalphC -- deeply appreciated!

Howdy All, Having this same issue here; choosing Color Picker brings up an RGB dialog screen, can't summon the Color-Wheel and crashes Media Composer. I previously could access the Color-Wheel in Titler+, but for some reason it's not responding now. Has there been any resolution to this problem? TIA

nigelad, for ingest an 8 core, w5500x, 48gb should do fine. The 12 core, w5700x, 96gb would be a strong editor. You can upgrade to 96gb later as I did with OWC and save some money while still getting quality ram.

Glad you got that sorted out, Roger. Frustrating why some files load and others don't, with seemingly little/no differences between them.

Did you ever find a jpg solution, Roger? I've been able to load GoPro timelapse, but having trouble with some older jpg stills. I did try altering names too, but no luck. Also having issues loading Sony Venice 4k footage from an AXS-R7, using nablet 4.6.7. Sony Catalyst provided a workaround but hoped for a more direct workflow.

Have you tried Sony Catalyst Browse as addinski suggests? https://www.sonycreativesoftware.com/catalystbrowse

Interesting that you've had the same issue on an older Mac/Mojave...I haven't seen any freezing issues with Source Browser on my current configuration.

I'm having a similar issue; hiding Media Composer to work within another app freezes MC when I return. I can quit MC and restart, however all transport control is frozen. It may be a 7,1 16 core issue...take a look at my specs.

Since moving to Mac Pro 7,1 been using EditReady2 from Divergent Media; https://www.divergentmedia.com/editready Simple & fast, can't complain at all thus far.

10.15.4 / 2020.4 Trying to import short Prores422 clip via Source Browser; getting the "not supported for import" warning. When selecting the "consolidate/transcode" option, receiving "unknown file" message.
