I didn't know that, Thank You.

We can't directly compare bit rates from two different camera models, even if they both use the same codec family.

A camera with a stronger processor can produce better results using a slower bit rate. Conversely, a camera with a weak encoder might need to dump out high bit rates to compensate for the relative lack of compression.

Indeed, a camera with high bit rate might actually be inferior than another camera with a lower bit rate, even if they both encode H.264.

For example, the Canon 5D Mark II has bit rates in the 40 mbps range, twice the average bit rate of the D7000. That doesn't mean the 5dmk2 outputs higher quality footage than either the D7000 or the Sony HXRNX5U. Rather, the 5dmk2 encoder is of an older design which requires relatively high bit rates to achieve good results.

Use a fast card if you're recording on High.

Bit rate differs between 1920 x 1080 High Quality and 1920 x 1080 Normal Quality movie recordings.

Resulting file sizes also differ with the same recording time.

Example:

Frame size/rate Movie quality Maximum length Resulting file size when recorded full length:

1920 x 1080 24fps - High quality 20 minutes Approx. 2,900 MB
1920 x 1080 24fps　-　 Normal quality 20 minutes Approx. 1,700 MB

According to my estimate using the above information
High = 19 mbps
Normal = 11 mbps

To compare this, a Sony HXRNX5U $4,950 msrp, professional camcorder shooting @24P can be set between 17mbps to 24 mbps.

So the Nikon is not bad at 19 mbps.

yeah...I stand corrected.

I think bitrate is the actual right answer

>> Close...I believe it is frames per second or FPS

No, that is a separate setting. "High: and "Normal" quality settings are strictly compression rate... frame dimension and aspect ratio and fps are unaffected.

I don't know for sure, but it could be the bit rate. Like 18mbps vs 24mbps.

24fps is cinema effect
30fps is video effect

Most likely has to do with the type of compression used when encoding the video. High would be the best quality, at the expense of higher memory use, while normal would be more compressed.

I will appreciate a lot to someone who explain me the differences between 1920x108024p high and normal video settings.
