Multimodal summarization for videos aims to generate summaries from multi-source information (videos, audio transcripts), which has achieved promising progress.However, existing works are restricted to monolingual video scenarios, ignoring the demands of non-native video viewers to understand the cross-language videos in practical applications.It stimulates us to propose a new task, named Multimodal Cross-Lingual Summarization for videos (MCLS), which aims to generate cross-lingual summaries from multimodal inputs of videos.First, to make it applicable to MCLS scenarios, we conduct a Video-guided Dual Fusion network (VDF) that integrates multimodal and cross-lingual information via diverse fusion strategies at both encoder and decoder.Moreover, to alleviate the problem of high annotation costs and limited resources in MCLS, we propose a triple-stage training framework to assist MCLS by transferring the knowledge from monolingual multimodal summarization data, which includes: 1) multimodal summarization on sufficient prevalent language videos with a VDF model; 2) knowledge distillation (KD) guided adjustment on bilingual transcripts; 3) multimodal summarization for cross-lingual videos with a KD induced VDF model.Experiment results on the reorganized How2 dataset show that the VDF model alone outperforms previous methods for multimodal summarization, and the performance further improves by a large margin via the proposed triple-stage training framework. * Equal contribution. † Corresponding author.Portuguese (Pt) Transcript: vamos falar hoje sobre o solo.em primeiro lugar, precisamos de uma grande quan dade de solo bom para transplantes na primavera.ela vai adicionar partes iguais de musgo de turfa e composto de jardinagem que extraímos do nosso sistema interno de compostagem, e então um agregado orgânico, uma pedra chamada perlite, que serve para adicionar volume e aumentar a capacidade de retenção de água e de aeração de sua mistura...
