$99 a film, reported within one business day
Paid checks open soon, starting with captions; artwork and metadata checks come next. The caption checker is free now.
Why check before you submit
- Filmhub gives a title three tries at QC.If it hasn’t passed Standard QC after the third, it can’t be distributed through Filmhub.
- On Filmhub’s free plan, QC lists the problems but doesn’t fix them.Fixes come with paid plans, from $499 a year.
- Indie Rights replaces failed captions at your cost.One failed file fails the whole delivery drive, and its guide warns that redoing QC can delay a release by several months.

How it works
Send a link to your files
Captions, metadata and artwork, shared from Dropbox or Google Drive. Tell us the aggregator, runtime and frame rate. We never need the film itself.
We check every rule
Each file against your aggregator’s current published rules, which we re-read before every check.
Get a cited report
A delivery expert reviews every finding. Each one quotes the rule and links to it, so you can fix it with confidence.
What we check, and what we can’t
We check
- CaptionsFormat and encoding, line length, lines per caption, reading speed, time on screen, gaps, SDH sound descriptions and speaker labels.
- Timing we can check without the filmCaptions made for another frame rate, captions an hour late from an editing timeline, and captions past the end of the film.
- MetadataRequired fields, length limits and title formatting.
- ArtworkSizes, shapes and file types for each image the aggregator asks for.
- The whole packageEvery file your aggregator requires is there, named and formatted the way it asks.
We can’t check
- Caption sync with the dialogueWe never see or hear your film, so we can’t tell whether each caption appears when the words are spoken.
- Word-for-word accuracyWhether every caption matches what’s said. Anything that needs judgment, like spelling or style, is flagged for you, never changed silently.
- Your video and audioPicture, sound and the film file itself.
No check can guarantee acceptance. Your aggregator makes the final call.
Check your captions free, right now
Our Filmhub caption checker runs in your browser. Your file never leaves your computer, and every finding quotes Filmhub’s rule.
How your files get checked
- Checking scripts test every rule that can be measuredLine length, reading speed, timing, image sizes, character limits. The same file gets the same result every time.
- An AI assistant drafts the reportIt flags anything that needs judgment, like spelling or style, instead of changing it.
- Tyler Gohr reviews every findingHe takes out anything that’s wrong and signs the report before it reaches you.
At Warner Bros., most of the rejections I saw came from captions, artwork or metadata, not the picture. Fixing those causes one by one took our iTunes acceptance from 32% to 96%. I read every report before it goes out.

Get notified when we open
Paid checks aren’t open yet. Tell us where and when you’re delivering, and we’ll email you when they open. Which aggregators we build next depends on your answers.
We’ll use your email only to tell you when we open, and perhaps to ask about your delivery. We won’t share it or add you to a newsletter. To have it deleted, email hello@sidecarqc.com. We count visits with Cloudflare Web Analytics, which uses no cookies. The form uses Cloudflare Turnstile to block bots. If you followed a link with a tag (like ?from=reddit), we save that tag with your sign-up.
Questions
Who does the checking?
Software, including AI tools, checks each file against the aggregator’s rules. Tyler Gohr, a delivery expert, reviews every finding before the report reaches you. Anything that needs judgment, like spelling or style, is flagged for you to decide, never changed silently.
What happens to my files?
You send a share link from Dropbox, Google Drive or similar. We download the files, use them only for your check, and delete them within 7 days of delivering your report, or sooner if you ask. Please turn off the share link once we have them. We never need the film itself.
Do you guarantee my film will pass?
No. Your aggregator makes the final call. It can change its rules without notice, and it reviews things we can’t, like sync and picture. We check against its published rules, re-read before each check, and every report says which rules and dates we used.
Do you check caption sync?
No. We never see or hear your film, so we can’t tell whether each caption appears when the words are spoken, or whether every word matches. We do catch captions made for the wrong frame rate, captions that start an hour late because of an editing timeline, and captions that run past the end of the film.
What does $99 cover?
One film checked against one aggregator’s rules: its captions, metadata and artwork, with a cited report within one business day.
Why not just rely on Filmhub’s own QC?
On a paid Filmhub plan ($499 a year and up), its Asset Adjustment Service can fix some problems for you, like caption sync. On the free plan, QC sends a report of the issues but doesn’t fix them, and a title gets three tries. We check before you submit, so you can fix what we find before it costs you a try.
Are you part of Filmhub or any other aggregator?
No. Sidecar QC is independent and isn’t affiliated with Filmhub, Indie Rights, Bitmax or any streaming platform.
