An attempt on 7D's HD video - A chef @ work

HD version

Normal version

It is only 2 mins and almost 700mb on 1920 @ 24fps. But took almost 1 day to upload to YT.

I do know that I was talking in the background and the ambient noise is noticable. Trying to make the subject feel natural and at work.

I am unsure if the picture was in AF mode all the time, as camcorder do.

It is my attempt and any comments are appreciated.

maybe you can compress it a bit?

Download MPEG Streamclip. Its a very good compression tool a lot of people use including myself, you could easily cut that file size almost in half with no noticeable quality loss

I have that program but I converted it to AVI with default settings but the my AVI file size is exactly the same... Can you tell me the settings to use?

your focus was fine. the 7d will not focus while recording and while in video mode you have to push the autofocus button or manually focus. but since you were at such a short focal length and and high fStop and all that jazz you had a pretty deep focus so there shouldnt be any worry as far as that goes.

the video looks great, not the most interesting thing to watch but i love 7d footage because of the great quality you can get with it.

I'm hungry now! That looked tasty

When you're shooting video, it's MF only unless you set it up to contrast AF (not very accurate I'm afraid) on the shutter half-press.

I'd advise you to convert and render the footage in editing software, you'll have much more flexibility with the final outcome even if you're not cutting anything together.

When you actually go to render your footage from the editing suite, you can alter how large you want the file.
For web viewing i'd advise you keep it to 720p, 1080 is overkill for almost everyone, a good delivery format is h.264, probably most handy is MP4.

The main variable for controlling the file size is the bitrate or 'datarate'. Measured in mbps/kbps, unsurprisingly its the amount of data being allocated per second. The lower the bitrate, the more compressed the data is, the smaller the file size.

For HD on the web, 6-8mbps is a good balance of quality and file size. I got my 8 minute film to look lovely at 125mb. You can go much lower, especially in standard definition.

You can also select VBR, or 'Variable Bitrate', this means depending on the frame the quality can vary as necessary for better quality/compression. Most codecs will allow you to define a minimum rate, a max rate and a target rate. There's also 2 level VBR which is even more picky, but this will increase render time compared to fixed rate.

Another way to chip a few bytes off is to have a play with the audio bitrate. For web you're not going to need more than 128kbps audio, a lot of presets for some reason like to set it to 320kbps audio which is unnecessary for web.
