“I work in the video & cinema industry since 20 years. Checksub is one of the most advanced and powerful tool i ever used for my subtitles. Not a second lost to understand the tool or to implement concretely the subtitle in my video and in the platform. Smart & efficient!”
“I had very very bad results (no matches at all in the generated subtitles). The customer service claimed I selected the wrong source language to cause this, but this was not the case. Another platform brought way way better results for the same price and with the same source mat”
“Je teste actuellement , mes vidéos sont en arabe ce qui n'est sans doute pas le plus facile pour les expressions etc... Je vais comparer avec une video traduite par une traductrice humaine, mais il me semble que c'est quand même pas mal du tout !!!”
“I like checksub very much, the reason I don't give it 5 stars are below: - the editing process could be optmizied, for example there is a Find & Replace function but not a "Find" only option. You can't search for a specific word in the subtitles and jump to that location - you ”

“I do contract work for companies looking to spread their videos overseas - tbh this is a pretty useful prgram. I used to use heygen, but my friend recommended me to try checksub. Overall, it's easier to use for my purposes, and it's cheaper too - sometimes they ask for some sound”
“Je dépose cet avis pour alerter sur les pratiques de facturation de Checksub. À l'origine, j'ai souscrit à une période d'essai pour tester l'outil. Le résultat ne m'ayant pas convaincu, j'ai immédiatement entrepris les démarches pour annuler l'abonnement et faire valoir mon droit”
“Be wary of the free trial, they don't send out any notifications about the ending duration of it like most brands do. I just tested it out once and left for vacation, seeing that I was charged for the WHOLE price of a FULL YEAR. I wrote immediately to the support team after see”
“I was promised extra credit because a simple refund is not possible in this company, immediately after I paid and did not order anything (red flag), and I did not receive it. After that the chat was cut off. They are scammers, do not trust this sevice. 0/5”

Can Checksub preserve background music when dubbing videos?

How do I get started with Checksub?

Does Checksub offer lip-sync technology?

This feature costs 5 credits per minute of processing and helps create more natural-looking dubbed videos where the AI-generated speech appears to sync with the original speaker's mouth movements.
