Create scroll stopping videos for social

Add subtitles to videos? That can be really tedious and time-consuming. However, if you create video content, having your videos captioned is a must! Why? It’s simple:

  • 85% of videos on Facebook are watched on mute,

  • 80% of people are more likely to watch your video to the end if it contains captions,

  • your videos can reach more people including hard of hearing or deaf people,

  • having manual captions in YouTube videos can boost your SEO.

That’s why video captioning is critical – but also very annoying and time-consuming if it’s done manually.

Add captions to video fast with little or no cost

Outsourcing video captions can grow in expenses really quickly, but on the other hand, captioning just several minutes long video can take hours of suffering.

ContentFries Captions Editor can generate automatic captions on your behalf, so you can caption your social media videos much faster with little or no cost if you write captions manually or paste the video script.


Hardcode captions to video

Social media videos often include captions, because content creators realize how important captions are for a successful social media campaign.

If you want to make your videos more engaging, we recommend hard-coding your captions to the video.

Of course, you can do this manually in some video editing software, but it may take hours just to create captions for a few-minute-long video.

With ContentFries, you may accomplish precisely this in minutes!

Get automatically generated subtitles with stunning accuracy

Get automatically generated transcription and subtitles in three simple steps:

  • Upload your video file

  • Choose language

  • Modify and export

Upload your video file

To upload your video, just drag and drop it from your device. Alternatively, you can use our Dropbox or Google Drive integration for a very fast upload, or just paste a direct video link.

Upload your video to ContentFries

Choose language

Choose from a wide selection of more than 120 supported languages and dialects. See supported languages. Then proceed to the final step of the uploading wizard and finish the process.


Modify and export

After you finish the uploading process, ContentFries will automatically generate subtitles.

Now you can modify them as needed, fix typos, or change timing.

Hard-code subtitles to your videos online

Hard-coded video subtitles are a part of the video, which means they can not be turned off.

This is a common practice for creating videos that are optimized for watching without sound.

With ContentFries, you can customize your captions and:

  • Use custom fonts or choose from a wide library of hundreds of beautiful fonts,

  • Change the location of subtitles in your video,

  • Change the size and color of the subtitles,

  • Apply shadow,

  • Apply backdrop and more.

It doesn't end with subtitles though. You can also add a beautiful progress bar, catchy headlines, emojis, logo, images, and other elements to your video.

Export subtitle file

It's very easy to export your captions as an srt file or other captions file format.

Just head to the "export" tab and choose which captions file you're interested in, including .srt, .vtt, or plain text file.

Advanced metrics

It is easy to follow best subtitling practices. Just by clicking a button, you can show CPL (characters per line) and CPS (characters per second) columns, so you can immediately see if some of the caption lines need attention.

We recommend you to keep your captions under 32 characters per line and under 20 characters per second. If some of the captions are too fast, you'll see the corresponding column in red color.

Simple presets for social media

If you're creating videos for Instagram Reels or TikTok, including engaging captions can help you increase engagement.

Once you click on the "advanced captions editor", you'll be able to use the "split captions by every nth word" feature. This way you can split your captions by every third word, which will generate dynamic captions great for short-form video content.

Toggle compressed mode

By clicking a button you can toggle the compressed mode on or off. In this mode, you can modify your captions as a text box.

How can I add captions to video online manually?

Upload your video and write subtitles

The automatic transcription feature is fully optional. You can turn it off in case you don't want to spend your monthly credits and wish to write subtitles manually.

This is how it works:

  • Upload your video file;

  • Turn off the "Generate captions from video automatically" option;

  • Use the [TAB] shortcut to play/pause the video and write what you hear;

  • Open up the "Advanced captions editor" and click on "Recalculate captions".

The best thing is that you don't have to manually sync the subtitles with the audio, as the advanced captions generator can help you with that in no time.

Just write what you hear as if you were writing it in a text document, and once you finish that process, use the "recalculate captions" feature available in the advanced captions editor.

Paste your video script as a source for captions

If you have a video script, you can copy and paste it to the captions editor and let ContentFries sync the text with audio.

The process is pretty straightforward:

  • Upload your video file;

  • Turn off the "Generate captions from video automatically" option;

  • Finish and paste your script to the captions editor;

  • Open up the "Advanced captions editor" and click on "Recalculate captions".

This way you don't have to spend time with manual captions timing, which is an extremely time-consuming and tedious task.

You can also customize how many lines per caption should be generated, and the maximum length of a caption line in characters.

Use the timeline to modify timings manually

It is very easy to make manual adjustments to the timing of the captions thanks to the timeline available at the bottom.

You can change timing with drag and drop to make any caption shorter or longer, or fine-tune the settings.


How can I get the most out of video subtitles?

Making video subtitles takes time and effort, but by doing so, you can leverage it in your content marketing and get the most out of your content.

Hard-code subtitles to bite-sized video content

As we discussed, hard-coding subtitles into video is a great way to make your video optimized for people who watch them with the sound muted. 85% of Facebook videos are watched this way.

Import caption files to YouTube videos

You can import plain text or a captions file with timings like srt to your video, which can help you boost your video SEO.

Export transcription as plain text and use it as the outline for an article

It's much easier to write an article if you have an outline or topic to write about. Also by repurposing your video into text format, you can attract more people.

Naturally, some people prefer videos, while others like articles and podcasts. This can help you reach more people and build your omnipresence.

PRO TIP: Multiply your video into dozens of content pieces

ContentFries automatic captions generator marks every word in the transcription with the correct timestamp.

This makes content repurposing very simple and efficient.

This is how it works:

  • Upload your video to ContentFries Trimmer and choose its language;

  • Generate automatic transcription, or import your .srt file or video script;

  • Use the transcription as a text document to multiply your video.

It's like turning potato into fries. The long video you want to repurpose like this is the potato.

It can be almost anything: interview, webinar, Q&A session, live stream, Zoom call, or YouTube video.

The longer the video is, the more pieces of content you can create out of it this way.

You can also choose the platform where you plan to publish the content piece, and ContentFries will automatically alert you in case the bite-sized video is too long.

Turning potatoes into fries is a fundamental feature of ContentFries, which makes us different and with which you can get the most out of your content.

Many of our users were able to create hundreds of content pieces this way, and you can do the same.

If you want to replicate what Gary Vee and other well-established content creators are doing, but you don't have the luxury of a content production team, ContentFries is the right tool for you.
