So when I export, I look at my content and guesstimate if the 16Mbps preset is good enough or if I need ot use one of the presets I built that allows for more data.įinally there is generational loss. Why Snow and Confetti Ruin YouTube Video Quality: I could sit here and type for the next 3 hours but instead, here are some videos athat do a great job explaining these concepts.
The problem is that the ammoun of data needed to get a decent image using the algoirthms isn t universal.Ī video of a man sitting calmly in a chair on a static background uses a lot less data per second that a space battle between two armadas. That's all the data that preset allows and for some videos that's more than adequate.Ĭomputers use a LOT of different tricks to reducde video file size: chroma subsampling, macro block compression, predictive frames, bi-directional predictive frames. or 16 Mega bits of data per second of the video.
Video uses compression to help squeeze out as much content as possible with as low a file size as it can get away with. this is done to speed up the editor when your edit starts getting a bit too heavy for your PC. Those settings don't affect the export quality, just the preview quality while you work. those pulldowns control the quality of the PREVIEW INSIDE THE EDITOR. In the lower right corner of your viewer and trimmer there are a couple of pulldowns next to the magnifying glass.
