If you have a choice, Export to MPEG-4 (.mp4) with .264 codec and VBR2 (Multi-pass option). This will give you the most quality per file size. Loading to YouTube it does not really matter, you can have multi GB files loaded and YouTube will re-render them to smaller file sizes. So if that is your destination, keep the quality high and large. You could use VBR1 in that case which saves some time and uses simpler compression. You can use even less compression to give YouTube better files to recompress. You should make shorted sections of your tutorial. A 4hr lecture will not go down well for anyone involved...

I now know how to record a Photoshop session. I have old OS, so have to use Quick time for it. No problem, but: I want to essentially record a full 4 hours (or so) process and then edit it some and eventually use it for teaching and run it at a faster speed, and talk live over it in a zoom workshop. Hillary Wilson did this for a talk she gave during the AMI annual meeting Webinar series last month. Her photoshop painting skills are breathtaking and it was amazing - and a very effective way to teach. I made a c. 4 minute recording, and QT saved it as 800 MG, so 4 hours will be unmanageably huge. I did a re-save at 1080 ppi and it dropped to less than 400 MG, but still - seems too big. The 2 lower quality file save options were too low res. to be useful. Any ideas how these are done?
