Which software (Mac) is recommended to convert from Inter-frame codec to Intra-frame format
What software is currently used (for Mac) to convert files from Inter-frame codecs (good for delivery ie. MP4) to Intra-frame formats (good for editing). I found and old Telestream article explaining this but it is years out of date. The article said choose these formats for editing: ProRes, DV, M-JPEG, JPEG2000, Animation, x264 (lossless mode).
I understand the current version of Quicktime doesn't allow this anymore (lossless mode).
My needs are small and occasional, so the software needs to be reasonably intuitive.
I typically would be inputing mp4 files @ 1080p 2 channel which are not in a desired format for editing, and am looking at outputting ProRes, DV, M-JPEG, JPEG2000, Animation, x264 (lossless mode) files as per the article: https://telestreamblog.telestream.net/2012/04/save-yourself-frustration-use-editing-formats-when-editing-2/
