![]() PrPro uses certain practices within the formats/codecs and you have control over much of it. So I hope somebody recognizes what clueless newbie error I'm making. Experimenting with essentially randomly selected values is a problem because the computer I use was never intended to be used for video editing and each pass takes 15 to 20 minutes. My objective is to create an MP4 file that can be stored on a corporate server for use by those who need the training and to keep the file size close to the original. The "estimated file size" is 581MB and the actual rendered file is 717MB (better, but still 4 times the size of my original file). I tried changing the target/max bitrate to 1 and 2. The "estimated file size" is 2086MB and the actual rendered file is 869MB. I tried changing the target/max bitrate to 4 and 6. Output: H.264, 1024x768, 10fps (it's a drop down, so I can't enter 8), bitrate VBR (1 pass), target/max bitrates 10/12 (based on what I've read on the forum, I suspect that this is what I need to change), audio AAC 32KHz mono (medium quality). Source: 1024x768, 8fps, with 8000Hz stereo soundtrack. The resulting video is 1 hour 10 minutes. After trimming about 30 minutes from the file in Premiere Pro, I exported it and the resulting file is 975MB (nearly 6 times the size of the original). The WebEx player can export its ARF files as MP4 files and I started with a file that's 169MB (the presentation is about 1 hour 45 minutes in length). WebEx has an editor, but it can't edit WebEx ARF files. I've been asked to edit a WebEx presentation to remove periods when nothing is happening. So I hope that somebody will be able to give me a clue in plain English what's going on here and how to fix it. Warning: I know my way around CC's audio, photo, publishing, and website applications, but I am pretty much hopeless when it comes to Premiere.
