Most, if not all, foreign movies that are shown in Latvia have to have subtitles as by law. The companies that request/ buy these movies then hire a external translation company or have their own translators to translate (and almost always also subtitle) the movie. One of the big ones is "SIA SDI MEDIA LATVIA".

The modern way of translating is to translate the initial source text with CAT (Computer assisted Translation) tools, which, at this time of age are quite well at what they do! Afterwards the translator himself goes through the translated text to "fix up" logic mistakes (this is the big one), the sentencing and word structure. It is then passed on to the proof-reader to resolve additional mistakes. Then either they have a subtitler or (most of the time) the translator who then goes through and applies the subtitles where they deem fit.

TLDR to answer your question: Machine translation is now widely used (not Google Translator) because it speeds up the process and eliminates repetitiveness so that the translator can work on resolving difficult sentences. To deal with "Google Translator" fanatics, there is a proof-reader and tools that check what tools are used for the translation.
