Video Translation is failing, both in API and on Speech Studio

Question

Video Translation is failing, both in API and on Speech Studio

Paul Rony 0

Video translation worked last month, but seems to have died. Seems like an Azure problem as the issue can be duplicated on Speech Studio, thereby ruling out my code (was previously worked).

The translation record shows success, but the iteration record show failure.

Hi Paul Rony

Sorry for inconvenience.

I just tested my speech studio located in "EastUS" for video translation to Japanese. It worked.

Attached screenshot for proof.

Currently testing in Curl commands as mentioned with SAS Urls of video as mentioned in this document.

Please allow us sometime to replicate in Curl commands and update you.

Could you test with other videos URL aside from storage blobs.

Could you share the region and confirm if the resources are virtual network protected by any chance.

Thank you.

Correct me if I'm wrong, but Speech Studio should work and should not be bound by the potential problems you have mentioned. Yet, Speech Studio fails with unhelpful message "Failed to translate file due to an unspecified error. Please try again later." I really should specify the error so that we would have some clue as to how to solve the problem.

I have tried switching resources in Speech Studio. I have tried different videos (but ones that translated in March 2025). I have tried switching subscriptions.

Same problem every time.

I have checked the services to see if some budget was set and reached, but found no budgets specified in any of the resources & services I have tried.

It is getting to the point where I may need to switch to Amazon Speech translation because this system simply no longer works. I can't run a business on an unreliable system that simply says "Failed to translate file due to an unspecified error". It has been a week and I have not been able to solve this problem.

Hi Paul Rony

Really Sorry for the inconvenience.

I have requested sample videos or data for replicating the issue.

With respect to the error

"Failed to translate file due to an unspecified error.

It might be due to format or size of the videos are you are inputting or testing in a unsupported region.

Video file requirement

You need a video file in .mp4 format, less than 500 MB, and shorter than 60 minutes. For testing purposes, you can use the sample video file provided by Microsoft at

https://speechstudioprodpublicsa.blob.core.windows.net/ttsvoice/VideoTranslation/PublicDoc/SampleData/es-ES-TryOutOriginal.mp4.

Prerequisites for Video translation

Below is region supported for Video translation - East US

Reference -

supported-regions-and-languages

Could you please also share the Sample SDK code to doing iteration and translation for checking any discrepancy.

Would really appreciate your collaboration on this matter.

Thank you for understanding.

First, the videos that are failing now are ones that previously succeeded. This specific video is under 10 min and under 15M, but other test videos were under 2 min and under 5M. They are still failing today.

Interesting that the TryOutOriginal does work. My videos were originally in WMV format and were first converted to MP4 before uploading using cloudconvert.com service.

FYI, the failing videos are failing in the Speech Studio, so it seems safe to say that it is not code related.

Hello @Paul Rony ,

I am able to reproduce your issue, the reason you are getting this error is audio codec encoding.

By default, it will be acc while converting in WMV to MP4 | CloudConvert.

So, i tried with setting audio codec before converting, click on settings button and change it to opus.

enter image description here

and

enter image description here

Know try the output mp4 file in speech translation studio.

Output:

If above solution works, please do accept the solution and give feedback by clicking on yes, and let me know if you have any further query.

Thank you
