now i have made a test run with the Handbrake. i used as source one Juras-Erglis Pontu video of length 1 h 52 min (of which most was dark nighttime). the conversion took 18 min which is ok.
there one shortage in Handbrake: it only converts the source video. that means that if (and when
as in dealing with 4-hour Pontu videos) one wants to make short clips one has to use some other program to clip the video. making clips is possible with VLC by making a recording of the wanted episode.
editing the video, like manipulating brightness and contrast, is impossible both with Handbrake and VLC. for these tasks i think i'll still use AVC.
i made (again) a little survey in the web looking for information about video editing and conversion tools in Finnish (i have a funny feeling that Finnish nerds might be more reliable and unbiased critics in describing these tools, but i don't know
if it really is so.) one of these pages was Neptunet.net which describes itself as a "website of information technology information with practical information on computers". there are also pages on video editing tools and video formats conversions. they describe for example the terminology in a way that gives a layman (and -woman) a feeling of understanding these things a little (if one understands Finnish in the first place).http://neptunet.net/2013/04/09/videoide ... untaminen/
in the above page they also warn about harmful programs and computer viruses which may spread with free video converter programs. i found similar warnings when i read reviews and critiques of video converters and editors on English-language pages, too. (see for example the discussion under this review:http://www.techradar.com/news/software/ ... ad-1136264
any way, i think that the Finnish Neptunet-page sounded reliable and they gave a list of free and payable video convertors and Any Video Converter was on the top of the freeware list. i think this is some evidence of it being reliable and good.
