    Since you are cutting video in pieces, applying filters and all the fun stuff, you are transcoding it anyway.

      Yes, but then you would be transcoding an already transcoded video, potentially making the losses apparent. It would be better to just transcode once at the exporting process.

        Lossy encoding only happens once in both cases.

        How direct import-export works: input file -> lossy format decompressor of editor -> filters -> lossy format compressor of editor -> output

        How external codecs work: input -> external lossy format decompressor -> intermediate representation(lossless codec, can be just storing raw frames) -> IR decoder of editor -> filters -> IR encoder of editor -> external lossy format compressor -> output

        Both options have only one lossy step - lossy encoder. Or technically two - also filters, but this is editor’s intention.

          Oh, I get it now, you mean using a lossless format as intermediate. Well, it would work but still it would be better if they didn’t require this extra work on linux.
