    My main activity is multicam videoing of amateur stage shows. For years a typical one hour show/Act has given me an exported video master (Cmd + E) of about 50GB but with the latest version of FXP (10.6.5) with Ventura 13.0.1, I noticed these are taking almost 200GB. I don’t think I’m doing anything different from before and I was wondering if anybody else has noticed this.

    Oh dear – I think I’ve got it. I looked in the setting for the Export and I seem to have specified the Video Codec of “Apple Prores 4444 XQ”. I can’t remember changing to that! Anyway, I tried it again with the ‘Source’ option (“Source – Apple ProRes 422” as it turned out), ran the export again and the output fie ended up a much more reasonable 65GB. Phew! I also compared the two files for image quality difference and to me there was NO difference but then I don’t have the latest and greatest equipment. So please stop panicking on my behalf 😉

    And to round things off I created an MP4 from the “Apple ProRes 422” file and that reduced the same video size down to 2.87 GB. About 1% of the “Apple ProRes 4444 XQ” file! To my not-so-bad eyes there’s no worthwhile difference. Interesting, at least for me.

    If you’re dealing with 1080 footage, H.264 is going to be just fine, anything else is overkill.

    Yeah, that’s the situation. Goodness only knows why I changed it. All good now and reasonable file sizes again. Thanks!
