Apparently I mis-posted this before, as I can’t find it in the forum. I apologize in advance if this is too far afield, but I need to start somewhere. I am hoping someone here may have experience that can help.
Where I work, webinars are given in WebEx, which can also record them. I just gave and recorded a series of half-hour classes on using various MS Word tools. In order for our company to post them on our training site, the training director needs an .mp4, to which she adds a branded header. WebEx allows me to download in its proprietary .arf file and convert to .mp4 in its player/editor.
My first class required editing beyond WebEx's very basic editor, so I brought home the mp4 and edited in MVS12 Plat (I have 15 now, but have not had time to investigate it). It looked fairly good in the editor, but when I rendered in Internet 480p, the resolution was dismal, even at half-size on my 22-inch monitor. I ended up rendering in Internet 720p, which was acceptable, but the file size may be too large for the sit. The second two classes, unedited by me, had headers added to the mp4s I sent, by the training director, using Camtasia, and even with a moderate, fixed-size window, the resolution was not really good enough to see clearly the dialogue box and other screen details in my demo. I don’t yet have specs for what she rendered in.
I foresee a call to WebEx to try to find out what specs they can offer. Anyone here who is familiar with screen recording, or who can suggest to me what parameters I should be looking at? I know just enough to know, second hand, that between containers and codecs and conversions, life can get very complicated fast. Any guidance on bitrate, rendering codec from the list (either MVS 12's or 15's), audio compression for simple voice narrative, etc., to keep file size in check while maintaining adequate quality for my screen capture to be used for corporate training purposes? I doubt that Camtasia is ready for HEVC, but I need to consider where we can improve (and whom I'll need to persuade…).
Thanks.
