Canva Captions Alternative for Vertical Video & SRT

Short answer: Canva's Editable Captions are a strong choice when the finished product is a styled video with captions in the picture, made inside Canva. Use something else when you need a separate SRT or VTT file, a readability check before delivery, or captions for video you don't edit in Canva. The clean workflow: export the final MP4 from Canva, generate SRT and VTT with Video to Subtitles, and if you want them on screen, style and burn them with Subtitle Style Studio.

What Canva's captions do (from Canva's help center)

Taken from Canva's own help pages (see sources). Check them again before relying on a detail, because Canva updates features often.

• Editable Captions are generated for videos and supported audio files (M4A, MP3, OGG, WAV, WEBM) in video and other supported design types. They're "downloaded with your videos."
• More than 20 style packs bundle font, colour and animation, with live previews.
• Spoken language is detected automatically, or you pick it to improve recognition.
• Translate captions into another language is an option at generation time.
• Editing and timing: captions sit as a timeline layer. You fix text by typing, and fix timing by dragging a segment's start and end edges.
• Editable Captions are separate from the captions made by Canva's Accessibility tools (the "Show captions" button), and the editing features apply only to the former.

What we couldn't confirm on Canva's own pages: a separate SRT or VTT download for Editable Captions, and a published list of caption languages. Third-party articles make claims about both. We've left them out.

The two caption jobs, and why one tool rarely does both well

Burned-in captions can't be switched off or edited after export, and they aren't text. Search engines and accessibility tools can't read them. Closed captions don't survive feeds that ignore caption files. If a video goes to both a muted autoplay feed and a website or course platform, you want both. The open vs closed captions explainer goes deeper.

Why "Canva captions not syncing" happens

Canva's help center names the cause directly: caption timing may stop matching the audio after trimming or adjusting segments. The captions were timed to the clip before your edit.

Diagnose it in two plays:

1. Same gap everywhere? You trimmed the head of the clip. Shift the captions as a block.
2. Gap grows or jumps after a cut? You removed or inserted material mid-clip. Each section needs re-timing, or regenerate the captions.

The reliable fix in any editor is to caption last: lock the edit, then generate captions. If you need a file anyway, export the final MP4 and generate SRT from that export. Those timestamps can't disagree with the edit, because they came from it.

Workflow: Canva for design, VideoText for caption files

1. Finish and export the video from Canva

Export without captions if you plan to burn styled captions with VideoText. Export with Canva's captions if you're happy with their look and only need a separate file too.

2. Generate SRT and VTT

Upload the MP4 to Video to Subtitles, keep auto-detect or pick the language, then Generate Subtitles. Download SRT and VTT. On Free, files up to 30 minutes are covered, and downloads include two short watermark cues. Pro removes them.

3. Check readability for vertical video

A 9:16 frame is narrow. BBC's guidance for vertical video allows up to three lines, and notes that the 37 characters that fit across landscape come to about 25 characters in a 90%-width region of a 9:16 frame (BBC Subtitle Guidelines). The default 42-character wrap that suits landscape video is too wide for vertical. Check line lengths with the character checker and split long cues.

4. Style and burn, if you want captions in the picture

Open the cues in Subtitle Style Studio: 12 presets (five on Free), eight fonts, and you approve the rendered layout before the export runs. Or use Burn Subtitles in standard mode for size, position and background only. A pre-flight check warns if cues run past the end of the video.

From our test. We ran a 60-second 9:16 clip through Video to Subtitles (20 cues), then pressed Style and burn into video. That opened Subtitle Style Studio with the video and the SRT already attached. The 12 presets sit in three tabs:

Beyond the presets you get eight fonts (including Noto Arabic, Devanagari and CJK), Regular or Bold weight, text and highlight colours, a scale slider, Bottom, Center or Top position, background, safe areas and motion, and an Export styled ASS option. We previewed with Documentary. The export is deliberate: validate the preview, press Approve this layout, then export. One tip: the preview opens at 0.00 s, where our clip had no caption on screen, so pick a cue before you judge the style.

The burned MP4 from our Pro account came back at 720×1280, still 9:16, H.264 at 25 fps with AAC audio, the full 60 seconds, and no watermark. On Free, the page states: "Free exports retain VideoText branding."

5. Publish both

Upload the burned MP4 to feeds, and the SRT or VTT wherever a caption upload exists.

Worked example: one edit, two deliverables

A 60-second vertical promo going to a short-form feed and to a product page:

The caption text is written once and reviewed once. Every output comes from that approved file, so a typo is fixed in one place, not in three Canva designs.

Where the 42-character default goes wrong on vertical

A 42-character line that fits comfortably across 16:9 will either shrink to an unreadable size on 9:16 or wrap to three lines. For vertical work, re-break cues to roughly 25 characters per line, following BBC's 9:16 guidance, before burning:

00:00:06,200 --> 00:00:08,900

from the ground up

Two short lines of 21 and 18 characters read at a glance on a phone. The same text on one 39-character line would not.

Making burned-in captions readable on a phone

These are practical rules rather than style taste, and they hold whichever tool burns them in:

• Contrast beats colour. White or near-white text on a semi-opaque dark box reads over any footage. Coloured text with no box fails on busy backgrounds.
• Keep the bottom and right edges clear. Feed apps overlay buttons, captions and usernames there. Use the platform's own safe-zone guidance for exact margins.
• Two short lines beat one long one on vertical video.
• Don't let animation slow reading. Word-by-word pops look lively, but the viewer still needs the whole phrase on screen long enough to read. A useful ceiling is 20 characters per second for adult English (Netflix English TTSG).
• One style per series. Viewers learn where to look.

The guide making burned-in captions easier to read covers contrast and caption boxes in detail.

Checklist before you burn anything in

Burned-in captions can't be fixed after export without re-rendering, so check the file first:

1. Spelling of every name and product, because they're permanent once burned.
2. Line length suits the frame (about 25 characters for 9:16).
3. No cue under about a second for short phrases, so it can actually be read.
4. Nothing overlaps. Run Fix Subtitles first.
5. The approval frame in Style Studio shows the busiest shot in the video, not the cleanest.

Canva vs VideoText at a glance

When to stay with Canva

• The video is designed in Canva, goes to one feed, and the captions are part of the design.
• You want animated, branded caption looks and will judge them by eye.

When VideoText is the better fit

• A platform, client or LMS asks for an SRT or VTT file.
• You need captions checked for line length, reading speed and overlaps before delivery.
• You're captioning long recordings or a backlog you didn't edit in Canva.
• You need more languages with identical timing (see translate SRT to Spanish).
