Bitrate For Maximum Quality.

[Jabberwockxeno]

I'll admit, I don't understand bitrate as a concept that well. In my head, if you have to display 1000 frames of video at 30 frames per second, then you should be loading whatever data is needed per frame with enough time to spare for a smooth transition. Any faster is uneeded, any lower is deterimental. And it should be deterimined not by a file, but by the processing power of the device playing it. That's the end result when it comes to FPS anyways, right?

 

Anyways, what bitrate is good for the max quality possible, for both/either 720p, 1080i and p?

 

Would any other settings change the answer?

 

Thanks!

I'm even confused by what you said, so I'll just explain it my way and a little simpler lol. Pretty much, bitrate determines quality, but with H264 you can retain a lot of quality(depending on your H264 encoding esttings) at lower bitrates thus saving a LOT of HDD space. To get the max quality possible, you would need to record a video uncompressed(which the HD Pro does not support) which is about 50mbps or higher in most cases. That's the gist of it, completely lost on the frames per second part of your explanation though .

I personally keep the bitrate set to max in the game capture and during rendering to youtube I set the bitrate to around 5-7mbps. h.264, like Solution said, can retain a lot of quality while also having a small file size. What you're using the video for should also be taken into consideration. Since youtube's max bitrate is 5mbps (I think) then there's really no need to have it rendered any higher, I just do it because I want to minimize the video degradation.

I'm not understanding either of your posts.

 

In the options menu in the "capture" menu, there's an option where you can enter in a bitrate number.

 

My confusion is that bitrate refers to the amount of media data being processed per unit of time, which should be dependent on the processing power of the hardware being used to run it, setting a lower value than the hardware viewing it would just cap the read speed, higher would either make the video jumpy because the hardware can't keep up, or it would have no effect and the hardware would just read data as fast as it could.

 

Confusion aside, there is no "max bitrate" option, you put in a number. Right now, I have 15000 set, as that's the default for 1080i.

 

I'm NOT talking about rendering the video, which I am not even woriried about now, since roxio can't render a video without compressing it.

 

In other words, i'm asking what settings, bitrate and all, should I use to get the closest video to the original signal when capturing. I'll make a seperate topic for the same question for rendering when I get there.

I said in the first sentence of my post that you set the bit rate, which is referring to the game capture software, to the max a.k.a 15000. That is the highest quality you're going to get CAPTURING. You can only capture in .m2ts, the highest quality is setting the video settings to whichever HD setting (720p or higher), setting the video bit rate as high as it will go and that's it. My advice would be to capture in 720p since the majority of console games are upscaled to 720p. 1080i just looks bad for gaming in my opinion. There isn't much you can do to get the quality to look like the original. What you capture is what you get. Afterwards is a different story since you can sharpen the image a bit, add some brightness and contrast, add some more color and make it look better. LIKE I SAID, the capturing side of things is simply setting bit rate and resolution.
