How to add subtitles to videos generated by Sora -

What is Sora

Sora is a groundbreaking video generation model recently introduced by OpenAI, following the launch of ChatGPT. By simply inputting text, Sora can generate a 60-second video based on the user’s text input.

Although there are some text-to-video tools available on the market, there is a significant gap compared to Sora. The videos generated by Sora not only perfectly execute the user’s commands but also are of very high quality.

According to videos posted on social media by OpenAI, Sora can generate a variety of video types, including but not limited to close-ups of people, street views, animated videos, landscape videos, and vintage videos, among others.

Moreover, the videos generated by Sora include multiple camera angles and fully display details. If not informed that these are AI-generated videos, it would be difficult to distinguish whether they were made by photographers or generated by AI.

What is Sora’s biggest advantage?

Text-to-video generation was not first introduced by OpenAI; prior to this, companies such as Google and Runway had already launched large models for text-to-video generation.

However, the gap between these models and Sora remains significant. So, what is Sora’s biggest advantage?

Reducing the barrier to video production

Video production has always been a vast and complex process involving scripting, camera work, filming, editing, and post-production steps.

However, the advent of Sora has reduced the barrier to video production, especially for short videos, to almost zero.

Extending the duration of video generation

Currently, other text-to-video models on the market can support video lengths of only a dozen seconds, while Sora extends this to 60 seconds. This duration can meet the content requirements of most short videos and the length requirements of most commercial advertisements.

Improvement in video texture

According to videos released by Sora itself, the texture of its generated videos has reached the production level of “blockbusters.” In these films, changes in light and color, camera language, and even subtle changes in texture structure all exhibit high quality.

Moreover, its videos adhere to physical laws; for example, in a video generated with the instruction “a realistic close-up video of two pirate ships sailing in a cup of coffee” at 1 minute and 39 seconds, the movement trajectory of the two ships actually follows the laws of fluid dynamics.

Furthermore, in the videos released by Sora, one can also see the use of techniques such as ray tracing and tilt-shift photography. In its animated works, it is clear that the processing of each frame has reached a relatively high level, fully comparable to professional works.

Adaptive video to screen sizes

Sora can not only generate high-quality video works through text but also produce various screen-matching images according to different playback devices, such as widescreen and vertical videos.

This significantly enhances Sora’s adaptive ability to generate videos, meeting the needs of audiences with different device requirements.

Let’s take a look at the results of the video generated by Sora.

What are the disadvantages of Sora?

Despite its many shining advantages, Sora currently has several disadvantages and areas that could be further improved:

Inability to Meet Long Video Needs

Sora can currently generate videos up to 60 seconds in length, which is insufficient for longer video requirements. Therefore, it can only meet the needs for short videos. For long video production, one cannot rely solely on Sora and may need to stitch together multiple short videos, potentially leading to inconsistencies in video style.

Videos Generated by Sora Are Silent

At present, Sora can only produce silent videos. Although the visuals are quite exquisite, the lack of sound means that the videos convey limited information. More importantly, short video platforms are not very friendly to silent videos.

Consider whether you would enjoy watching a silent video on TikTok. Thus, it becomes necessary to manually add background music or voiceovers to videos generated by Sora.

No Guarantee of Content Authenticity

Given Sora’s realistic video generation technology, there’s a concern that it could be used to create videos that replace real news events for profit. This issue is not unfounded, as there have been instances where individuals have used tools like ChatGPT to modify and edit collected materials, presenting them as real news on various news websites.

Lag in AI Regulation

Many laws regarding AI-generated content are still in the process of being established. Understandably, establishing laws is a lengthy process, but technological innovation is rapid.

This has led to a global lack of regulatory laws concerning AI-generated content. Consequently, there’s a risk that individuals could use Sora or other AI video tools to generate content that violates laws or ethics, such as pornography or violence.

How to Make Videos Generated by Sora More Perfect

Provide Clear Instructions to Sora

Just like with ChatGPT, it’s necessary to give Sora clear instructions to ensure it can correctly understand your commands and produce the video you’re satisfied with. Refer to the relevant instructions provided by OpenAI and try multiple times to determine the video style you need. After that, you can generate related videos in bulk.

Add Voiceovers to Videos Generated by Sora

Currently, all videos generated by Sora are silent, and it’s unknown whether AI will add sound to videos in the future. However, adding sound to Sora’s videos can make them much more impressive.

Why Music is So Important for Videos

The main reasons are as follows:

The music in a video sets the emotional tone.
Music adds to the atmosphere of a video.
Music can help attract more video viewers.

In essence, the music in a video is a critical factor in determining its success or failure. Therefore, we need to manually add voiceovers to silent videos.

How to Add Voiceovers to Sora Videos?

Generally, you can use three main types of voiceovers in a video:

Human voices: This can be narration from off-screen or the voice of characters speaking on the screen.
Background music: If you want to enhance the atmosphere of the video or provide a deeper viewing experience, you can add various kinds of background music that are independent of the plot.
Special sound effects: Sound effects can be any sound, from the popping of balloons to the bustling noise of city streets, or the sound of wind, rain, and other sound effects you need.

Adding Subtitles to Sora Videos

If you need to present Sora-generated videos perfectly to your viewers and get higher viewership, then in addition to dubbing the videos, you need to add captions to Sora-generated videos.

Why Subtitles are Needed for Sora Videos

According to the BBC, data from Stagetext shows that three-quarters of viewers aged 18-25 say they use subtitles all or some of the time.

The charity’s research suggests that if more live events and performances had subtitles on screens at the venue, an average of 31% of people would attend. Among the 18-25 age group, this figure is 45%, while it is only 16% among those aged 56 and older.

A survey by Preply of over 1260 Americans found that:

50% of Americans watch content with subtitles most of the time.
55% of Americans say it is harder to hear dialogue in shows and movies now than it used to be.
62% of Americans use subtitles on streaming services more than on regular TV.
57% of people watch shows in public places; 74% of Generation Z do so.
