5. Cropping and bitrate calculation

Here you will use the cropping window and bitrate calculator in yatta to decide good values to use in your final generated avisynth script and which bitrate to use when finally encoding. These windows can be found under right-click\additional in yatta but only the bitrate calc is accesible without opening any file. All of this assumes you've already got a project opened yatta but no modifications are necessary before doing this.

Cropping and Resizing

  1. Move the slidebar to a bright frame where you can easily see the edges of the video.
  2. Increment the x and y values until all black parts of the video are covered.
  3. Use the zoom window to spot miscolored lines and fuzzy edges. You need to crop those away too.
  4. Determine a resolution where the aspect ratio won't be too far off (field turns yellow) or check anamorphic which will instead give you the optimal final display size to enter in the matroska muxing step. The resizing fields turn yellow if the selected resolution isn't mod 16.

Bitrate Calculation

  1. Press 'Add audio stream (file)' and select the files you encoded in the previous step.
  2. If you're calculating the bitrate for the currently open project the time has already been entered (vfr projects have a noticably shorter time because of how the final avisynth script is generated).
  3. Enter the desired filesize. Look in the guidelines to see which filesize is recommended for your encode (230MB is usually a good value for one anime episode).
  4. Don't forget to write down your bitrate somewhere since it won't be saved with the project and you need it for the divx settings.
Warning: The bitrate calculated for vfr files is just some pseudo value that will give you the right final size and shouldn't be listed as "actual" bitrate.
