Again, those are just containers. Most likely they are MPEG 4 (codec), which is supported by the Fire TV, but that does not mean that divx/xvid/MPEG 4 is supported, Amazon doesn't make the distinction.

Yes, h.264 may be having the same or similar issues but that doesn't mean that they are caused by the same thing and it depends on what you mean by "jerky" since if you have a lot of jerkiness then it's not the same as h.264 which is small and irregular.

But as far as recommendation, either mkv/h.264 or mp4/h.264 which are more "universal".

Also, you don't necessarily need to re-encode. You could just run them through mkvtoolnix and do container swap, which should only take a couple of mins. per vid.

I am very into this idea and downloaded mkvtoolnix to give it a whirl but I'm kind of lost. Is there a guide you can point me to? The program suggests a few guis to try but they both seem geared toward using an mkv file as input.

I don't know what platform you are on, but assuming it is linux or os x I just ran this as a quick test as i'm in a similar situation to you and it seems to work just fine:

Code:

find /media/raid/testconvert/ -name "*.avi" | while read i; do mkvmerge -o "${i%avi}mkv" "${i}"; done

Replace "/media/raid/testconvert/" with the path to your Movies. That command will find all .avi files and convert them to .mkv

Nice script! For those that want to keep their original timestamps, you can run this after you do the conversion. It will copy the original date over from the avi file:

Code:

find  /media/raid/testconvert/ -name "*.avi" | while read i; do touch -d `stat -c %y "${i}" |cut -d  ' ' -f1` "${i%avi}mkv" ; done
