This is a known CapCut issue when Auto Captions were used at any point in the project, even if you later delete them.

What you are seeing (infinite “Loading…” on export) means something in the project timeline is silently failing to render.

Why this happens

From your description, the key trigger is:

• You used Auto Captions
• Then removed/replaced them

CapCut keeps hidden caption metadata or corrupted subtitle layers, which:

• don’t show visually
• but break export rendering

How to resolve this issue

Below we suggest these effective methods

1. Copy timeline into a NEW project

This fixes hidden corruption almost every time.

Steps:

1. Create a new project
2. Go back to the broken project
3. Press Ctrl + A → Ctrl + C
4. Paste into the new project (Ctrl + V)
5. Try exporting again

This removes hidden caption artifacts in the project file.

2. Remove hidden caption tracks (even if invisible)

Sometimes captions still exist as a “track.”

Check:

• Timeline → look for Captions / Auto Captions
• Toggle track visibility
• Delete anything caption-related again

3. Render/export in parts

This helps isolate the issue.

Try:

• Export only first half of the video
• Then second half

If one part fails, you’ve found the corrupted segment.

4. Replace problematic clips

Auto captions sync to audio—so audio clips can cause the issue.

Try:

• Delete the audio track
• Re-import it fresh
• Re-align it

5. Turn OFF hardware acceleration

Even if you adjusted performance settings, double-check:

• Settings → Performance
• Turn OFF:
  • Hardware encoding
  • Hardware decoding

CapCut export bugs freeze on GPU encoding.

6. Export via “proxy workaround”

If it still hangs:

1. Duplicate the project
2. Lower resolution (e.g., 1080p → 720p)
3. Export
4. If it works → upscale later

7. Force re-encode trick

Make a tiny edit:

• Move one clip slightly
• Add/remove a frame
• Change export name

This forces CapCut to rebuild the render pipeline

If the above methods does not help you solve then:

Then your project file is corrupted specifically by captions.

Final workaround:

• Export XML/EDL-style recreation manually:
  • Rebuild timeline in a new project using same assets
  • (annoying, but guaranteed fix)

Important message

Even though you: “removed all text boxes”

CapCut still stores:

• timing data
• speech segments
• caption engine references

That’s what breaks export—not the visible text.

Most recommended fix based on my experience for your situation:

1. Copy everything into a new project
2. Disable hardware acceleration
3. Export

That solves ~90% of cases like yours.

We can talk through your exact timeline setup and pinpoint the exact failing layer if you can describe more details after trying the above methods.

Vamos por partes para que puedas solucionarlo o al menos minimizar el impacto

En CapCut han introducido el sistema de créditos para IA generativa, separado de la suscripción Pro. Eso ya de por sí ha generado muchas quejas.

Sobre tu problema específico:

• La IA no está respetando la duración solicitada (180 s)
• Genera videos:
  • demasiado cortos (<1 min), o
  • demasiado largos (>3 min)
• Y cobra créditos igual, incluso si el resultado es incorrecto

Esto suele pasar porque:

• La IA prioriza el contenido generado sobre la duración exacta
• Interpreta mal el prompt (muy común en IA de video)
• Hay bugs recientes tras la actualización (esto es bastante probable ahora mismo)

Qué puedes intentar

1. Ajustar cómo das la instrucción

En lugar de decir solo “3 minutos”, prueba algo más específico:

• “Haz un video de 3 minutos”
• “Duración EXACTA: 180 segundos (ni más ni menos)”
• “Video dividido en 18 escenas de 10 segundos cada una”

Cuanto más estructurado, mejor responde la IA.

2. Generar en partes (hack útil)

En vez de pedir 180 s de golpe:

• Genera:
  • 3 videos de 60 s
  • o 6 de 30 s
• Luego los unes manualmente

Esto reduce errores y evita perder tantos créditos en un solo intento.

3. Usa imágenes/clips propios + IA solo para guion

Otra estrategia más estable:

• Deja que la IA te genere:
  • el guion
  • la estructura
• Pero arma el video manualmente en CapCut

Así evitas depender del generador automático que está fallando.

4. Revisa si hay opciones de duración ocultas

A veces (según la versión):

• Hay ajustes como:
  • “Auto duration”
  • “Match content length”

Desactívalos si están activos.

5. Reporta el problema (MUY importante)

Esto es clave porque afecta créditos:

En CapCut:

• Perfil → Settings → Feedback / Report a problem
• Email capcut.support@bytedance.com

Si suficientes usuarios lo reportan, suelen corregirlo rápido.

Sobre los créditos

Lamentablemente:

• CapCut Pro ≠ créditos ilimitados de IA
• Son sistemas separados (y bastante criticados)

Y sí, tienes razón en esto:
No deberían cobrar créditos por resultados defectuosos

Ahora mismo:

• No uses muchos créditos en videos largos (180 s)
• Trabaja en segmentos cortos hasta que arreglen el bug

When trying to export a different video. it works flawlessly.

Only difference is that on the affected video I used Auto Caption, and not on the other. This was used with the free credit so no premium issues should be occurring.

I manually removed all text boxes produced by the captions and replaced them with standard boxes yet the issue persists.

I have made all changes to performance tab reccomneded by other issues and posts, still no resolution. 

File size is less than 1gb.

Entonces, si le digo que me lo prepare de nuevo, me resta los créditos del primer video que me generó mal y no me los devuelve para que me haga el video como yo le pido. No respeta los tiempos que le pongo y, encima, me quita créditos por un mal video o trabajo que le pido.

Mi cuenta es Pro y no tengo por qué pagar de más para crear los videos. Deberían añadir los créditos a los usuarios que son Pro y que no tengan que pagar de más.

This is actually a common issue with CapCut Dreamina, and it is usually not your birthday that’s the problem but it’s how the system handles age verification.

Why it keeps rejecting your birthday

1. It doesn’t use what you type

On the web version (including Dreamina), CapCut does NOT store your birthday from that screen.

Instead, it pulls your age from whatever you used to sign in like TikTok, Google, Apple, etc.

So:

• You type your birthday → hit confirm
• But the system checks your linked account → mismatch → it loops or doesn’t proceed

2. Cached / bugged session

Sometimes it just gets stuck because:

• Cookies/session data are broken
• The page fails to refresh after input
• Temporary server glitch

3. Age restriction triggers

If your linked account says you're under the required age:

• It may silently block progress
• Or just keep you stuck on that screen

CapCut enforces age limits (which is 13+ or higher depending on your region)

What you should try

Fix #1 — Check your login account birthday

This is the BIG one.

• If you logged in with:
  • TikTok → check TikTok DOB
  • Google → check Google account birthday
  • Apple ID → check Apple ID birthday

Make sure it matches your real age and is above the minimum age to use CapCut.

Fix #2 — Log out and use a different sign-in method

Try:

• Instead of TikTok → use Google/email
• Or vice versa

This bypasses the stuck birthday loop.

Fix #3 — Clear browser data

Do this exactly:

• Clear cookies + cache
• Or open the site in Incognito / Private mode

Then reload Dreamina and try again.

Fix #4 — Wait 24 hours

If you just changed your birthday on another account:

• It can take time to sync across systems

Fix #5 — Try mobile app instead

The CapCut mobile app:

• Shows an “appeal” or verification option
• Lets you get past the block

Fix #6 — Disable VPN if you are using one

Your region can affect age rules.
VPN = higher age requirement sometimes.

If nothing works

Then it’s mostly a bug or account flag.

Your options then:

• Contact CapCut support
• Or create a new account with correct DOB from the start

Can you post a reply to this thread regarding:

• What you’re signing in with (TikTok / Google / etc.)
• And what exactly happens when you press confirm (if you can share a screenshot then better)

The “Object” option you are looking for doesn’t really exist on CapCut PC the same way it does on mobile.

Why you can’t find “Object” (CapCut PC vs Android)

• On CapCut mobile, there’s an “Object / Background / Person” toggle inside Effects (especially in Body/Video effects).
• On CapCut PC, that specific button/menu is not there or limited.
• Instead, CapCut PC uses a different workflow which is more manual control based.

So you are not doing anything wrong as the feature just isn’t in the same place.

What to use instead on CapCut PC:

1. Apply effect to a specific clip

• Go to Effects tab
• Drag the effect directly onto the clip in the timeline
  • This applies the effect only to that clip (not globally)

2. Use Mask + Keyframes which comes closest to “Object” effect

If you want effects on just a person/object:

• Select your clip
• Go to Video → Mask
• Choose a shape (circle, custom, etc.)
• Adjust it over your subject
• Add keyframes to follow movement

This is how PC replaces the “Object” targeting feature

3. Use Cutout / Background removal

• Select clip
• Look for:
  • Cutout
  • Auto Cutout / Remove background
• Then add effects to the separated layer
• This isolates the object so effects only apply there

4. Use Overlay method

• Duplicate your clip
• Put one layer on top
• Apply effect to only one layer
• Use mask/cutout to separate object vs background

Video tutorial for PC method:

• Mobile = automatic “Object” button
• PC = manual tools (mask, cutout, layers)

PC is actually more powerful but just less beginner-friendly.

Lets say if you are blurring the background in CapCut PC which is totally doable, just a bit more manual than mobile. Below we will show you a way

Method 1: Auto Cutout (Easiest)

This is the closest to the “Object” feature from mobile.

Steps:

1. Add your clip to the timeline
2. Right-click → Copy (duplicate it)
3. Place the duplicate on top layer
4. Select the top clip
5. Go to Video → Cutout → Auto Cutout
6. Now select the bottom clip
7. Go to Effects → Blur and apply a blur effect

Outcome:

• Top layer = subject (sharp)
• Bottom layer = background (blurred)

What this looks like

Method 2: Mask + Blur (Manual but precise)

Use this if Auto Cutout doesn’t detect your subject well.

Steps:

1. Duplicate your clip (same as above)
2. Select top clip
3. Go to Video → Mask
4. Choose a shape (circle or custom)
5. Position it over your subject
6. Feather the edges for smooth blending
7. Apply blur effect to the bottom clip
8. Add keyframes if your subject moves.

Method 3: Use Body Effects

CapCut PC versions include:

• Body Effects → Background Blur

• Just drag it onto your clip
• It auto-detects the subject (like mobile)

Note that it might not be available in all versions yet. So you will need to update CapCut PC to the latest version.

Tips for better results

• Increase feather → makes blur look natural
• Use Gaussian Blur for realistic background
• Slightly scale up the blurred layer to avoid edges showing
• If Auto Cutout flickers → switch to Mask + keyframes

CapCut PC works like this: Put your subject on top, blur the layer behind it

CapCut on Windows can crash like that, and it is because of memory or GPU issues rather than just a random bug.

Quick fixes to attempt:

These solve a lot of CapCut crashes immediately:

• Restart CapCut + your PC
  (clears RAM leaks that build up during editing)
• Close heavy apps
  Chrome, Discord, games—anything eating RAM
• Run CapCut as Administrator
  Right-click → Run as admin
• Update CapCut
  Old versions crash more often

If it’s a Memory crash which is most likely cause

CapCut can be surprisingly heavy.

Check your RAM

• Press Ctrl + Shift + Esc → Performance tab
• If RAM usage is near 100% → that’s your crash

Fixes:

• Lower video resolution (edit in 720p instead of 1080p/4K)
• Remove heavy effects (blur, transitions, AI stuff)
• Split your project into smaller parts

GPU issues which is another very common cause

CapCut relies on your graphics card.

Try this:

• Update GPU drivers (NVIDIA / AMD / Intel)
• Or disable hardware acceleration:
  • CapCut Settings → Performance → turn OFF GPU acceleration

Clear CapCut cache (important)

Corrupted cache = constant crashing

Steps:

• Open CapCut
• Settings → Cache
• Click Clear cache

Last resort fixes to try if it’s still crashing

• Reinstall CapCut completely
• Install it on SSD (not HDD)
• Make sure your Windows is updated

If your PC has:

• 8GB RAM or less
• Integrated graphics only

CapCut will struggle, especially with effects or longer videos.

Quick workaround so you can finish your Telegram video

If you’re stuck right now:

• Export in chunks such as short clips
• Or temporarily switch to something lighter like:
  • Shotcut
  • DaVinci Resolve (heavier but more stable)

Can you post these details as a reply to this thread:

• Your RAM (e.g., 8GB / 16GB)
• GPU (if you know it)
• Video resolution you’re editing

We can study a little more as to why it’s crashing and give you a fix tailored to your setup.

Masking in CapCut can feel tricky at first especially with keyframes because masks don’t automatically “turn off.” What you are seeing that the mask continuing and growing is expected behavior unless you explicitly control it.

How Masks work in CapCut:

• A mask applies to the entire clip by default
• Keyframes only change the mask, not whether it exists
• So unless you “remove” or isolate it, it will persist through the clip

Best ways to start & stop a Mask

Method 1: Split the Clip which is the easiest & most reliable method

This is the method most video editors are using nowadays:

1. Move playhead to where the mask should start
2. Tap Split
3. Move to where the mask should end
4. Tap Split again
5. Select the middle segment
6. Apply your mask only to that segment

Result: The mask exists only in that section so that no weird growth or carryover appears.

Method 2: Keyframe the Mask size to “Disappear”

If you really want to use keyframes:

1. Go to the frame where mask should start
2. Add a keyframe → set mask size/shape normally
3. Go to the frame where mask should end
4. Add another keyframe → shrink mask to:
   • Extremely small size, OR
   • Move it completely off-screen

• CapCut interpolates between keyframes, so if the mask is “growing,” it means it’s transitioning between sizes/positions
• To stop growth:
  • Keep the same size/position across keyframes
  • Add an extra keyframe right after the end point with the mask “hidden”

Method 3: Use Opacity trick (Overlay Method)

If masking an object:

1. Duplicate clip as overlay
2. Mask only the overlay
3. Keyframe overlay opacity:
   • 100% when mask needed
   • 0% when not
   • This gives you a true “on/off” feel

Why your Mask keeps growing?

This happens because:

• You set different mask sizes/positions across keyframes
• CapCut automatically creates a smooth transition (animation)

To fix this:

• Add a keyframe right before movement starts
• Keep values identical between keyframes where you want no change

If your goal is simply to hide something briefly, don’t fight keyframes as splitting the clip is cleaner, faster, and more predictable.

Can you tell us a little more details like what you are trying to hide like face, object, moving item, etc.? We can recommend a setup specifically based on your situation.
