hello,
i just recently got a smartphone for christmas and now i wanted to put
some of my videos on it. this tecnology is all new to me and i tried
around with transmageddon and iriveter but none of them does the job
right. now i thought it might be a good idea to try it with ffmpeg but
unfortunately i am not very familiar with it. so i wanted to ask you
guys for some advice in the settings, it's a samsung gio gt s5660.
thanks
If your smartphone is not HD, you can simply convert all to DV format,
which is the best for Cinelerra.
Let's say your smartphone saves files in 3gp format, just open the
terminal, go to the folder where you copied the files and write (all in
a row):
for i in ./*.3gp; do ffmpeg -i "$i" -target pal-dv ./`basename $i
.3gp`.dv; done
Try "ntsc-dv" if the resulting stream is not smooth.
Obviously, change those two "3gp" in something else if your files have
different extension.
If your files have better resolution than 720x576, and/or you want to
keep the same codec/quality for video, just write:
for i in ./*.3gp; do ffmpeg -i "$i" -vcodec mjpeg -sameq -acodec
pcm_s16le -f mov ./`basename $i .3gp`.mov; done
This is mostly "universal" :-) but it takes a lot of disk space. It's
totally lossless.
Remember to write down the characteristics of the final files (frames
per second, resolution, etc., you can see them with VLC: Tools → Codec
Information) and copy them into "Format" tab in Cinelerra.
Then, after video editing, render in "Quicktime per Linux", with "JPEG
Video", 100% quality in video settings, so you'll have a totally
lossless video you'll encode with Handbrake or Transmageddon or Arista
or ffmpeg or WinFF or whatever you like.
