Hei!
I just finished a music video trailer for a client, he loved the filming, the coloring and the montage, so all went very well. The result is a 1-minute square HD video, which takes about 90Mb of space.
Now one of his markets is an Asian country, and he asked me if it was possible to get the size down to 4-5Mb (!) and then, after talking a little, 10Mb. What he tells me is it's about the bad internet connections in these places (my guess is that it makes it difficult for people running marketing channels down there to upload.. once uploaded, size shouldn't matter at all of course).
I didn't commit because I think the quality of 1m of video compressed to 5Mb would be rather horrible. I tried the Magix codec to 360p, and yes, I get around 5Mb but it looks terrible, pixelated and with color smearings - something I would never put out for my own band.
We had very little time to get the formats, so the best I could do (and they were happy) was to export the video to my phone and use iMovie there to compress down to its "medium" setting (I guess 360p) and the result was about 25Mb with a quality acceptable on a small phone screen. All went well in the end.
But since nobody's asked me before to get down to such small size, I wonder if there's something more I could have done, or any codec which comes with Movie studio that could help?
