• Google Lato Font Display discrepancies between platforms/software [closed]

  5 juin 2024, par CRAIG

  Using Google's Lato font with 400 weight, is giving me some inconsistent results between Photoshop/Web on MacOS and Linux Imagemagick & Linux ffmpeg.

  


  I have printed out some text on my linux server using the font using both imagemagick (v6.9.10-68) and ffmpeg's (v6.0) drawtext feature and in both cases, I get some extra space between the T and the e. (Image below)

  


  At first I was only testing ffmpeg and thought it was related to drawtext, but now that imagemagick is doing the same, I am thinking it may be somehow related to how the server is managing the font ?

  


  I did download the exact same font to test on my Mac and installed it, but I still get the original photoshop results I was getting before. So I don't think it is inherently the font unless I missed a step. I did completely uninstall the font and then install the downloaded one to be sure.

  


  However, the same word, font, font-size combo used in Photoshop and on the web does not produce the same space between the T and the e.

  


  Here is an image I put together showing the results :

  


  

  


  For reference, here is the imagemagick command :

  


  convert -size 900x900 xc:black -font /fonts/Lato:400.ttf -pointsize 261.6 -fill white -gravity center -annotate +0+0 'Text' testoutput.png

  


  And the ffmpeg command :

  


  /usr/local/bin/ffmpeg -f  lavfi  -i  color=c=black@0.0:s=953x953:r=30:d=5,format=rgba  -filter_complex  "drawtext=expansion=none:enable='between(t,0,5)':fontfile='/fonts/Lato\:400.ttf':fontcolor=0xffffffff:fontsize=294:text='Text':x=(w-text_w)/2+0:y=476.5-(max_glyph_a)+(294/2.8)"  -copyts  -threads  1  -c:v  png  -pix_fmt  rgba  -movflags  faststart  -r  30  -t  8  -y  testoutput.mov

  


• Finding File Matches & Variable Assignment using a .BAT Script

  6 octobre 2019, par A Person — batch-file, ffmpeg

  I am trying to assign a file to a variable in a batch-file and then also assign another 2 files into anoter variable.

  However, I am having an issue.

  From research, I found how I can do the assigning but does anyone know how I can do the below.

  From a folder or text file, (either is fine), find the .m2v video file and assign that to Var1 then find matching audio in .wav and put that in Var2 and the third is also an audio .wav with mathcing name and assign that to Var3.

  The problem I am having is trying to find the matching 2 audio files to the video.

  The video file is named as :

  PAV_PRG_13683Highc450277201906251802090353.m2v

  Audio 1 is :

  PAV_PRG_13683High01c450211201906251802090376.wav

  Audio 2 is :

  PAV_PRG_13683High00c450211201906251802090368.wav

  The file name matches until it sees the word High. Everything after High is not needed, (it is just a random string), so trying to match is an issue.

  Is there a way to find the match by comparing everything before High.

  Also as I will be using the variable and putting them through ffmpeg to merge, is there way to do it so that when the ffmpeg command has completed, it moves to the next matching files and assigns them to the variable.

  The files are store in 2 folders, one folder has all the video files *.m2v and another folder has all the *.wav audio files in pairs of 2. Each video has exactly 2 audios, (left right).

  is there any help on this subject, I have already come up empty in my research and have been checking for this over the last week spent almost 30 hours.
