While there are video encoders that do this kind of thing, most commonly this is the work of a video switcher or mixer. A video switcher is a device used for mixing live video from multiple sources. The bad news is they generally aren't cheap. An HD capable switcher is typically in the $6000+ range with the absolute cheapest one I know of being the Black ...

The bands you're referring to could well just be a limitation of the 8-bit colour space. In theory the way to solve this is to use 10- or 12-bit colour space through every stage from rendering, to editing and mastering, through to output and even in the screen or projector. However your final output is probably going to be displayed in an 8 bits per ...

The output is an .MTS file, which is ~450 MB. What is the reason for that? It is desirable to record and master in the highest quality possible, and only convert to lower bitrates for delivery (if necessary) at the final stage. 450MB for two minutes is 30mbps. That's not particularly high for a capture bitrate; it's a typical capture bitrate for ...

HD video is very, very large at high quality. 450MB for two minutes isn't actually that bad. To put it in perspective, assuming you were shooting 1080P and 24fps, if there was no compression applied, that same 2 minutes of video would be 6 gigabytes of information. The reason that videos you download or watch on bluray disks are so much smaller is that ...

Well the program that encoded the file that works was Apple QuickTime so not much of a suprise that it's working. QuickTime can be a little picky when it comes to mpeg4/h264 encoded files. I looked at the files and possible factors are the encoding profile and maybe the GOP setting. Basline Profile Level 3.0 for the broken one and Main Profile Level 3.1 for ...
