What to Look for in an H.264 Video Encoder
At the recent 流媒体 East conference in New York City, encoding expert 罗伯特•莱因哈特 (founder of VideoRx.com) told attendees what to look for when buying an H.264编码器.
"There's effectively three qualities that I think anyone would look for in a good encoder: quality, 速度, 和成本,莱因哈特说. "All three of these factors all working together, 我觉得, probably make up 90 percent of the decision-making that goes into any encoding workflow, and I think most of us really care about the first one that I put up there, 这就是质量."
While video quality is central, Reinhardt cautioned against trying to have it all.
“通常, you're probably only going to get two of these pieces of the pie way more than the third,莱因哈特说.
The good news is that every encoder can handle basic tasks pretty well nowadays. The decision, then, rests with smaller features. Once the basics are covered, what next? Codec options, for one thing.
"Beyond that, what do I look for in an H.264编码器? I'm going to look for multiple H.264 codec options,莱因哈特说. "I only really care about one these days -- that's x264. I'm not saying that Main Concept isn't any good, but Main Concept just seems to have a certain set of options, X264还有其他的. When it comes to adaptive streaming, you have much finer control in x264."
