Downsizing AVCHD to make it more digestable?

My HD footage is too high quality for a large segment of my intended audience! What to do?

After filming HD on a little Panasonic TM300 I have edited some short films in Premiere Pro that I have output in HD format and uploaded here on Youtube. Everybody is quite satisfied with the result.

However audience access to the films is becoming a problem as here in west Africa many people do not have access to high speed internet (though many do) and also many people (including my partners) do not have fancy laptops - so playing back DVD copies of the the videos on laptops is a problem. First, since most laptops are too slow, hard drives are too small, and DVD players are also too slow; second, since many laptops run on older operating systems that cannot playback HD unless the user first installs an extra program such as VLC media player, which not everybody has patience and technical skill to do. Third, many DVD players are older machines that do not playback HD.

As far as I can see to get around this problem I have the following options that have pluses and minuses:

(1) swap cameras and record in miniDV format. This would give me lower quality results yetl immediately resolve most problems mentioned above with local access at least in terms of compatability with older laptop and DVD players but may hurt prospects for circulation in Europe, USA and elsewhere if not now then certainly in future. Or do a lot of you guys who do semipro stuff like this still shoot miniDV and expect to continue to do so in future?

(2) continue to record in AVCHD but export from Premiere Pro in a different format? Which format? Do not most options for exporting AVCHD in alternative formats look really crappy?

(3) ?????????
 
I think your acquisition should be in the highest quality. This gives you the most options.

It's trivial to downgrade or convert to lesser formats, but the reverse isn't true.

There is no reason why you can't provide different formats. eg. A movie can come out on blu-ray as well as dvd. Youtube has HD but also has SD options. I'm sure you get the gist of what I'm trying to say...

If DVD is the medium for those folks, then give them a DVD, or instruct them to watch the low res version on the internet

Yes SD formats look crappy compared to HD, but if that's all they can play then there is nothing you can do. Then at least you still have HD format options you can distribute in to other viewers
 
Thanks PDR

I get the gist :-)

Will follow your advice and check if AVCD downconverted to SD is any worse than straight SD.

If not done properly, yes interlaced AVCHD downconverted to SD for DVD can be worse than straight interlaced SD from a high quality DV camera

Progressive downscaling is less of an issue, but most NLE's use a fairly neutral resize (bicubic), which may appear soft. This may or may not be desirable depending on what you want to do
 
Today I used the standard Win7 Windows DVD Maker to burn 10 small videos to a DVD. The files on the DVD are of three kinds: .inf, .bup and .vob (that I understand contains the actual video footage). The .vob files are considerably less MB than the original .mpg files and though the quality is not as good as the originals it is adequate for the type of distribution I mention above.

What I am a bit confused about is what Windows DVD Maker has done to my files???

This is a child-proof program that offers no option for selection of codecs etc. So I have no clear idea about what codec Windows DVD maker has used to encode my original .mpg files on the DVD and as a consequence how compatible the DVD will be with standard DVD players and/or WinXP computers?

I don't have access to a DVD player or a WinXP computer. So I would like to ask if anyone with experience using this or similar programs would expect the DVD should be able to playback on either of these platforms -- or would they require the use of a non-standard program such as VLC Media Player to playback the DVD, as my original files do?
