4 years ago Hi, thank you for the warm words!
- I think it is not a problem to use videos with a different language of narration. Audio information contains not only speech but also sounds of actions, background, etc. Therefore, I wouldn't worry about it too much unless I run an experiment.
- To use visual features only, you may specify
--model transformer(which by default isav_trasformer). Here is the script we used for the ablation study (use it as guidance because I don't expect it to work without some error – I refactored code a bit after that, so some arguments' names might be different etc)

Hey @v-iashin Thanks for open sourcing such an awesome work!!! Kudos to you on this and MDVC. I was wondering since my videos are not of English language but I do require captions in the English language, how do I go about utilizing your work here? Is there a possibility to totally ignore audio features and just image features?
