Hi Taina, I save my final videos as mp4s, which cuts down on file size. I did a video presentation at the conference - resolution: 1220x686 / 20 minutes / 250 MB (with a soundtrack). One thing I would not recommend is to make one file for a 4 hour presentation. Break it into sections. You can always stitch them together in the end, but working with smaller files will speed your work. For example - when I’m working on a book, I work on each chapter separately… so I don’t have to move through hundreds of pages, only 30 or so. Also, I don’t know how well iMovie would handle a project as long as 4 hours. There are good screen capture programs. I don’t recall the one I used to use (it’s not compatible with my current OS). I now use Camtasia - not cheap at $250, but reasonable if you have a lot of work to do. You can record and edit. You can add titling, animated annotations (like a circle being drawn around something you want to emphasize), you can show keystrokes, you can zoom in, there are transitions, etc. Expect a bit of a learning curve. I would contact them about an older version if you are interested. They also have a program called SNAGIT which is a screen recorder. I haven’t used it, so can’t comment. I haven’t worked with QuickTime lately. If you choose to stay with it, I would look at export options and experiment to see how you can reduce file size but keep reasonable quality. If you are working on a substantially older computer, I would check to make sure the final movie plays ok on a newer machine. To upload from QuickTime to YouTube, there is a 15 minute limit. I see longer videos on YouTube, so I don’t know if this is a QuickTime limitation or what. I hope that helps.

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? > > Taina > > -- > Taina Litwak, CMI > Litwak Illustration Studio > 13029 Chestnut Oak Drive > Darnestown, MD 20878 > > office: 202-633-4561 > mobile: 240-750-9245 > > https://urldefense.proofpoint.com/v2/url?u=http-3A__agresearchmag.ars.usda.gov_2014_sep_insect_&d=DwICaQ&c=Cu5g146wZdoqVuKpTNsYHeFX_rg6kWhlkLF8Eft-wwo&r=AGYZ7-AeerjxzYnIwL-lBLFI3SPYN3BDmku4qGQB4Tg&m=gKbaUaTf9JRXhv0GBzodkZNim3-tDWM05GVkFWj2EIQ&s=v3HWqPHk_PHhiqyWgcASwLb_eY5Bl97XoAiOS-1l2hw&e= > > Instructions to subscribe or leave the list are at https://urldefense.proofpoint.com/v2/url?u=https-3A__www.gnsi.org_listserv&d=DwIFaQ&c=Cu5g146wZdoqVuKpTNsYHeFX_rg6kWhlkLF8Eft-wwo&r=AGYZ7-AeerjxzYnIwL-lBLFI3SPYN3BDmku4qGQB4Tg&m=F3Qvi6q3cUWEwYQE7xHvGcPPbvpKtRAN0369GFNcI7A&s=1zhOc5k22wk2KjdjAoJut7ypJIVr_GYg2KrCOduCgo8&e= > > List name is Sciart-L > > Problems: Email Lana Johnson at [log in to unmask] Instructions to subscribe or leave the list are at https://www.gnsi.org/listserv List name is Sciart-L Problems: Email Lana Johnson at [log in to unmask]
