We usually have our first real cold spell right around Thanksgiving and, apparently, this year is no different. Right now, Tuesday, it is above 0°F and snowing. My mom will be visiting for the next couple of months and today we ventured out to College Coffeehouse. It was -16°F when we left the house and significantly warmer a couple of hours later.
Not much else going on. I only have a couple more hours on the IPv6 video plus need to add some titles, credits and lower thirds but most of the hard work is done. Trying to get independent audio and video streams to be in sync and adding in slides proved to be more of a challenge than I expected. Plus there were a lot of slides. Some PDF and some PowerPoint.
Happy American Thanksgiving!
So did you go to the coffeehouse in your rig? :D
ReplyDeleteTo be honest, it’s probably not leaving the garage for a couple of months.
DeleteI remember trying to get 2 streams to play together. If I remember correctly our best luck came from encoding multiple profiles so a third audio only stream was created. Then using JavaScript we had both video streams sync to that audio stream and if falling out of sync it would freeze or drop video frames. We were able to get it to function manually, but hit a wall when trying to automate the startup process as the player had to be tweaked each time with a timecode delay because both video streams didn't start at the exact same time. You could always try looking at how an open source lecture capture player works, such as Matterhorn. Good luck
ReplyDeleteFortunately, this wasn’t live. In the editor, I had the audio track running continuously and periodically resynched the video using the cameras audio. I had the camera audio muted but whenever the speaker coughed, I would take a look at the audio spike and adjust if needed. The speaker video is a small percentage of the output as most of the output video is PPT slides and audio. But it was an enjoyable project. Most of the work was done while we were in Los Angeles.
