    Re: HOWTO: Make Time Lapse Videos from Photographs

    Hello,

    Nice tutorial. Just one problem for me. I've got an output.avi of say, 89MB, and a MKV of 100M. What's the best option to compress that properly.

    I use following command line to convert it:
    avconv -y -i output.avi -c:v libx264 -preset slow -crf 15 output.mkv
    Thanks

    Check this link for more encoding options:
    https://trac.ffmpeg.org/wiki/x264EncodingGuide

    I guess if you change CRF to a higher value (23 is the default one) and/or play with bitrate, you will achieve the compression level you need.

    My intention with the command mentioned in this tutorial is to get a high quality video without artifacts, rather than compressing the video much (in your case obviously it's the opposite.. The final output is bigger).

    Thank you for the guide. I'll check it out.

    My purpose is to have a good quality/size ratio. When I'm travelling, videos and pics take a lot of space. And I don't need highest quality yet. If I'll publish it, it will only save time (as in some third world countries internet connections are fairly slow) if it's not too big.

    Re: HOWTO: Make Time Lapse Videos from Photographs

    Nice tutorial, thanks!

    1) I've ran into segfault when trying to do a TL video from more than 1000 pictures:
    Segmentation faultf (38%) 11.87fps Trem: 2min 809mb A-V:0.000 [77605:0]
    After this error I'm getting the video which consists of 1000 pics.

    I know I can make few parts and stick them together in another utility, but I want to make this process easier.

    2) >> I ran into some problems for some time lapses with this line of code:
    >> ls -1tr | grep -v files.txt > files.txt
    >> It should be:
    >> ls -1 | grep -v files.txt > files.txt

    Why? I have no problems with first command. Even the first command is better in my case:
    I have camera which makes number to pictures from 0001.JPG to 9999.JPG and after last number it creates another directory and starts over from 0001.JPG.
    so time sorting in ls command makes my video proper, when name sorting wil lscrew my video up.

    Was it mencoder gave you the segmentation fault?
    I never tried to make a timelapse with more than 1000 pictures before, but I could give it a try

    I don't remember exactly what was the problem, but I remember that for a specific set of pictures, they were not in order. However, with ls -1 everything was fine.
