1 minute=60 second, so it takes about 120 MB (or less, so lets say 1 minute=100 MB (mega bytes).

The resolution of a video refers to the number of pixels that make up a video. If you choose 10,000 kbit/s your file-size will be about 775 MB. You could put an Xvid file inside it, or a H.264 file, which would vary a lot in size and quality. This is also why 4K is off by default — you have to visit Settings > Camera > Record Video to change it. Depends on the compression used in the file, as well as how the content changes between frames - since compression is highly affected by how much changes happen. Average video render time is 15-20 minutes or so with an upload time of about 10 minutes per video. In a standard 720p video there are roughly one million pixels that make up the picture. A 4K video on the other hand has eight million pixels. The actual space taken up may differ slightly due to embedded audio, differing frame sizes and aspect ratios, and inter-frame compression / pulldown. 480i/30 – Frame size 720 x 480 interlaced with 59.94 fields per second. There are a number of video file converters available that can take a high rez mpeg or avi file and down convert it for use on the web. Folks, I am trying to understand the relationship between video bitrate, image size, codec, and the file size. The more pixels that make up the image, the higher quality it will be and the larger the file size. H.264 is a popular codec.

Therefore 1 hour=60 minutes would take 6000 MB, that is about 6GB. Remember, Quicktime is a wrapper for video that can a wide choice of video and audio compressions, H.264 is just one of them. Average video render time is 15-20 minutes or so with an upload time of about 10 minutes per video.

2)Length of movie MP4 and MKV are just containers and (at least with MKV) you can put basically any codec you want in it. When I search the forum all I can see the same as the specs, 4K resolution video with stereo recording Slow Motion: 720p video at 120fps.

It being MP4 or MKV doesn't really have anything to do with the file size by the way. I get around the times by mass rendering while I'm asleep and then uploading while I'm at work the next day. MediaInfo is a nice basic tool for quickly seeing all the parameters on a video file: A 4K video on the other hand has eight million pixels. Using Youtube as an example, uses a data rate of 2megabits per second for 720p video. If you just mean uncompressed video, then it could be calculated.

I'm looking for an order of magnitude estimate for expected on-disk file size for 1 hour of H.264 encoded HD video transcoded from HDV (HD on a MiniDV tape). For example, if I have a movie that has an image of 1920*1080 pixels, the bitrate is 24 MBPS, the length is 2 hours and the codec used is H.264, how can I approximate the file size? Since 1 byte 1B=8 bits, this means the bit rate is 17/8=2.1 mega Bytes per second (2.1 MB/s).
