推荐几种简单好用的生成视频素材的工具

2024将会成为AI电影的元年。随着4K图像转视频工具和口型模拟技术的成熟,人人都可以成为导演,制作高清的动画和短视频。不过,在制作AI视频的过程中,我们需要用到很多软件和工具。

今天,为大家推荐几种简单好用的生成视频素材的工具,帮助大家用最低的成本,制作高质量视频。

  1. 图像和视频生成:Midjourney

Midjourney V6是最强的图像生成工具,适合作为视频素材使用。在和RunwayML结合后,就可以生成高画质的视频。而且,RunwayML Gen2完成更新后,允许用户使用多功能移动笔刷,指定人物的动作和移动方向。RunwayML Gen2支持文本转视频、图像转视频功能,且提供了免费试用点数,也是很多用户的首选工具。

此外,Pixverse也是一个高质量的短视频生成平台。不但支持4K高清输出,还可以在网页端使用,非常方便。例如,上传一张图像,设置好Motion值,即可生成短视频;或者输入文本提示,选择一种风格,生成对应的视频。

除了以上两种工具,Pika也是一个功能强大的短视频生成平台。

Pika的特点是视频生成速度快,支持多样化的编辑功能,适合制作多种风格的视频。

  1. 音效和背景音乐

UP beat是一个免费的音乐和音效素材库,适合内容创作者使用。选择一个分类,即可视听音乐。UP beat提供的音乐均为无版权、开放下载的内容。点击download,即可直接使用。例如,选择电影分类,下载一段和马里奥游戏相关的音乐素材。然后,把制作好的短视频和背景音乐,进行合并。

点击左侧的sound effect按钮,还可以下载海量的音效。例如,使用下雨的声音,或者下载适合动漫和卡通场景的音效。

此外,Soundly也是一个知名的音效素材库工具。

Soundly包含了数百万音效文件,用户可以保存并整理常用的音效到云端,随时可以使用。

对于很多短视频创作者来讲,还会使用Suno生成五无版权的原创音乐。

  1. 口型匹配

Lalamu提供了便捷的语音合成和口型匹配工具。用户只需上传需要匹配唇型的视频,即可完成口形匹配和对白添加。

此外,Gooey也提供了免费的口型模拟工具。上传图像或视频文件,添加需要播报的语音,即可完成语音合成和唇形匹配。

DID Heygen为代表的数字人平台,可以生成效果很好的数字人模型,不过缺点是需要付费。

  1. 图像和视频增强

如果想要生成高清,或者4K分辨率的视频,我们就需要提高图像的画质和分辨率。例如,Stability旗下的clipdrop工具:Clipdrop – Image upscaler,可以将图像放大到16倍。

此外,大家还可以使用开源的Upscaly工具:Upscayl – AI Image Upscaler,完成图像的增强。

如果想要在原图的基础上完成细节的修复,还可以使用Krea的Upscaler:krea.ai/apps/image/enhancer工具完成。

  1. TTS语音合成:AI Voice Generator & Text to Speech | ElevenLabs

为视频添加对白也是重要的环节。Elevenlabs是最适合的文本转语音工具,且支持29种语言和语音克隆功能。

    While the cost of living in Portugal has gone up in the years since she moved there, it’s still “probably about 40% to 50% less” than in the US, says Dreyfuss, adding that it’s a “much better life day to day” for her.

    As for the language, Dreyfuss admits that this has been one of her biggest struggles, recounting how she’s always asking locals to “slow down” because they “they talk really fast, and drop whole words out of sentences.”
    [url=https://rutorclubwiypaf63caqzlqwtcxqu5w6req6h7bjnvdlm4m7tddiwoyd.com]rutor24x7 to[/url]
    “I can make myself understood,” she says. “But I sound like a three- or four-year-old.”

    When it comes to cultural differences, Dreyfuss jokes that it’s really hard to hang up the phone when speaking to a Portuguese person, and she’s had to learn not to walk into a shop and “just start talking” without exchanging pleasantries first.

    “You have to say, ‘Hello. How are you? Are you ok?’” she says, adding that anything less is considered bad manners. “But it just comes naturally now because I’ve been here five years.”

    Since arriving in 2021, Dreyfuss has traveled to London four times, Paris three times and the Spanish city of Seville twice. She’s also visited the Austrian capital Vienna, as well as France’s Marseille and Toulouse.

    In the coming months and years, she hopes to explore Italy and Europe’s Atlantic coast.

    “That’s something I would not be able to do if I didn’t live here,” she adds.

    Dreyfuss currently has temporary citizenship, which is renewed every two to three years, and recently began the process of applying for Portuguese citizenship.

    She feels very much at home in Portugal today and can’t imagine ever returning to the US permanently.

    “They’d have to fix an awful lot of stuff before I’d want to move back,” she says.
