I get this for all the options that I choose:
Unfortunately, the translation process failed with the following error:
Error: Unexpected server error: error-code: 500
I will be shortly looking into this. If this is a server problem, you are either not charged at all, or this order amount will be refunded in the next 1-2 days. If it’s not, please contact me ASAP. In case of any further questions or queries, please feel free to contact me and mention your order#.
Thanks for reporting this to me Jacob. There is indeed a problem going on the server, where it’s getting stuck. I’m looking into it and will update shortly once I have isolated the fix.
Thanks for the feedback. The Mistral Large 3 API seems to be heavily throttled by the provider at the moment. I’m not doing any other filtering on my end. Hopefully, once their servers stabilise, it will all start working automatically.
Hello Akbar, I paid for a translation, but when I play the movie, the subtitles are out of sync and disorganized. They were fine before the translation.
#5PA223806XXXXX.
In short, easy fix would be to use newer models (Chat-GPT 3.6+) which are far more better at keeping correct context or using the different “Translation Model”. I would suggest try using “Per-Line” or “Structured”. If still run into any issues, please let me know.
PS. I have also issued full refund of your payment.
Unfortunately, it’s not a bug. DeepSeek has raised its API pricing effective August 16, 2026. Rates have increased by 50% to over 1,100%, depending on the model, token type, and time of use.
That said, I have slightly adjusted the price to bear part of the cost. It’s still higher than before, but that’s the best I can offer at the moment. Thank you for your undertanding.
Hello Akbar
This tool was very useful for me, who is in Iran and cannot always be online and translate with PotPlayer
Thank you, but I wish the user interface was a little more attractive, although it is a really powerful tool.
Bulk or mass translation is already supported. You can upload up to 20 files at a time (and 100 for the registered users) and then translate all of these in single go. I hope this helps.
Sorry for the trouble. The legacy DeepSeek API model deepseek-chat and deepseek-reasoner were officially deprecated by DeepSeek on July 24, 2026. Please use DeepSeek v4 models. I will soon update my website to remove these models from the options.
I’m sorry for the trouble in downloading files. I assume you were using Google Translator in free mode? Unfortunately, free translations are not saved, so any intermittent failures are lost. If you don’t close the window, you can re-try after few minutes, and hopefully it will let you continue. If you can’t download any of the file, then something in your browser may be blocking it. I would suggest trying any other latest browser e.g. Chrome or Firefox. If the problem persists, please let me know.
“When I was using Gemini 2.5 Flash-Lite to translate the subtitles for Little House on the Prairie Season 1 Episode 1, I used the ‘Merge’ feature to generate bilingual English-Chinese subtitles. On one particular subtitle frame, there were two sentences: ‘No, not today. Today is special.’ However, the AI only translated the first sentence ‘No, not today’ for that frame, while pushing the translation of ‘Today is special’ into the next frame. This caused the translation for the next frame to be pushed to the one after that, and so on. This domino effect caused a long sequence of misalignments until it suddenly resynced later on. I only noticed this issue halfway through watching the video, and it really ruined the viewing experience. How to prevent this from happening in the future? Thanks!”
I’m sorry for the bad experience Anthony. This is unfortunately is a known problem with AI translators, where they sometime mix-up the context and do unintended shifting. The good news is that this is less frequent with high-end or latest models, but it’s still a problem. The best recommendation I can have is that try to visually inspect the rows quickly after translation. I have built in tools to fix these sync issues or re-translate a batch of problematic rows. You can read more about it here: https://blog.syedgakbar.com/subtitles-translator-help-tips/#shift-rows
PS. I have issued a full refund for that translation.
Hey, thanks a lot! Your site has helped me a lot with editing, and please keep the Google feature free, bro š. Iām even thinking about getting your plan.
I wanted to ask something: I translated an SRT file, and now I want the subtitles to appear in two lines instead of a single line. But whenever I import it into editing software, the “ tag also appears. Doing it manually isnāt really possible, especially for 30ā60 minute videos.
So is there any solution for this? Please let me know, bro. Thanks a lot!
Thank you for the feedback. Are you using Maximum Subtitle row length calculator on my website to split the subtitles into multiple lines? If not, I would recommend trying that and see how it goes.
BTW, it looks like the tag you mentioned got removed. Can you re-type it so that I can understand what’s going wrong and how to best fix it?
Hello Akbar;
can you please consider providing an API for your online subtitle translation? I really love your platform and think having an API would be incredibly useful for developers who want to integrate your translation service into their own tools (like me:).
Let me know if this is something you might add. Thanks for the great work!
Thanks for you feedback and suggestion. First of all, I’m glad you are finding this service of help.
Regarding API integration, this has been asked by few other members as well. However, as being a developer you already know, it’s a big project and I would love to do this neatly. I can’t commit on a schedule, but definitely going to add this in my high priority list. Once I have develop something, I will need some volunteers and I will then contact you for sure.
Hi, Akbar! i remember when i could translate srt file, but now when i try srt files canāt be picked from files for translate. Im on iphone i donāt know if itās only for me.
To cancel your subscription, please follow these steps:
1. Click on the current subscription name – on the left side of your balance display.
2. In the “Current Plan” dialog, click on the “Change” button at the bottom of the dialog.
3. It should show the “Subscription Plan” dialog.
4. In this dialog, select the “Free” subscription plan.
5. This would trigger cancellation of the subscription after your current plan expires.
Hi, Akbar!
Yesterday and today DeepSeek translator doesn’t work š¢š It tries to calculate cost, but returnes “Error: Unexpected server error: error-code: 500” I like DeppSeek so much, other models can’t translate from chineese so nice.
Best wishes, Nadya
Thank you for reporting this back to me, and sorry for the trouble. I have isolated and fixed the issue causing this failure. Can you please try this again?
Good morning, Akbar
A few minutes ago, I upgraded my subscription plan from “Free” to “Pro”. The payment has already been taken via “Stripe”, but shortly afterwards I received an error message saying that the Pro membership hadn’t gone through.
However, the membership did work, because on your website my āMembershipā has changed from āFreeā to āProā. I would still be grateful if you could take a look at my membership, as everything has always worked perfectly with āStripeā up to now, so Iām a bit confused by the error message that appeared afterwards.
And, before I forget: thank you very much for providing this excellent website for us users. The translations work flawlessly and the new āStructured (Preview)ā version is a real bonus.
Best regards,
Matthias
Thank you for being an active user of this tool and welcome to the “Pro” membership. I’m glad you have been enjoying these service all along and I hope you find the exclusive features worth it. In case you have any further suggestions or input, please do share.
Regarding the membership upgrade error, that’s a bit odd, because I don’t see any errors being logged on my server regarding this upgrade. And your membership has indeed changed to “Pro” level. By any chance do you remember the wording of the error message or have screenshot? I can then look further into this one.
Thank you for your feedback Harshita. I’m sorry to hear that you don’t like the new color scheme. I have been trying to modernize the layout, but still trying to keep it readable for majority of the users. I will give this another look and will try to improve this further.
Any particular section or area you find more problematic with new style?
Hi I tried to translate a set of Spanish subs but when I upload them, your program doesn’t recognize accented characters and substitutes a question mark where the accented letter ought be. For instance a word such as “DroĆÆde” is uploaded in the system as “Dro?de”
As you can imagine this completely defeats the purpose given how many words in Spanish contain letters with accents on them. Given the high occurrence of accents in Spanish, it’s impossible to go over each line and rehabilitate the text. One might as well hand-translate the entire file.
Hi, from your description, it looks like you are trying to translate files with non UTF-8 encoding. Even though my website tries to auto convert the subtitles on-demand, the algorithm to detect UTF-8 encoding is not foolproof, so might be failing there. Can you check your subtitles file encoding online (there are few online tools) and then try these again?
Otherwise, you can also send me a copy of these at my email address (see footer) and I can look into what’s going wrong there.
I get this for all the options that I choose:

Hi Akbar…
[Error: Translation is taking very long and is not progressing, so aborting it.]
it’s happening on Deepseek V4
Thanks for reporting this to me Jacob. There is indeed a problem going on the server, where it’s getting stuck. I’m looking into it and will update shortly once I have isolated the fix.
Regards,
Akbar
Okay, I think I have now isolated and fixed the problem. Apologies for the inconvenience.
Can you please try this again when convenient?
Regards,
Akbar
Hi Akbar…
It’s now [Error: Unexpected server error: error-code: 500] after loading the SRT file. Not just DeepSeek, but also for all other paid ones.
Ah, I’m so sorry. This started failing for all users on the free tier. I have now fixed the problem.
Please let me know if you run into any other issues.
Regards, Akbar
Hi Akbar,
thank you for your awesome tools, much appreciated!
I noticed that Mistral Large 3 is not usable at this time. Will it become available again?

Hi Nat,
My apologies for the bad experience. Unfortunately, this is a know problem with LLM based models due to inherent randomness. You can read more about why it happens and your workaround and solutions:

I really appreciate the professional translation, thank you
Hi, Akbar!
Excuse me, why DeepSeek translations became so expencive? Approximately x3 within couple of days. Maybe it’s a bug? (hope so š)

Add mass translate subtitles option, like upload 5,6 SRT files and one click all translated in same time

Just yesterday I used DeepSeek 3.1 just fine. But all of a sudden today I can’t. It says:
Error: invalid_request_error:The supported API model names are deepseek-v4-pro or deepseek-v4-flash, but you passed deepseek-chat.
Please help…

Did something happen to the free software? It doesn’t give me the option to translate from English to Hebrew for free?
Google widget based translation is still free and I just tried it. What translator you are using?

Hello, need help.
I use sub translatror for 5hr content, translated very well but I cant download it(timeout)?

Sometime, With google translate, there are around 15% of the subtitles is not translated (randomly at some part of the subtitles).
Thanks for reporting this back. What if you try to re-upload and re-translate? Does it always skip certain lines or their position is random too?
