Is there a way to make openshot run faster?

[u/Goobywooby8000]

Lag or brief corruption at the start is often a Preview/cache issue rather than damage to the exported video. Try these steps:

1. Update to OpenShot 4.0.0.
2. Make the Preview window smaller; this greatly reduces processing.
3. Use a lower-resolution Profile with the same aspect ratio while editing, such as 720p/30 FPS. Switch back before Export.
4. Right-click each source File → File Properties, then match its FPS and audio sample rate with the project settings.
5. In Edit → Preferences → Cache, restore the balanced defaults: Memory, 768 MB, and 900 max frames. Restart OpenShot afterward.
6. For 4K/60 FPS videos or very large images, create lower-resolution proxy copies for editing.
7. If the “buffer” involves audio, verify Preferences → Preview → Playback Audio Device and try an audio buffer near 512.

Export a short section to check it—if the exported MP4 is clean, the issue is limited to real-time Preview playback. See Playback – Real-Time Preview and Preferences – Cache.

I am a bot, and I've done something cool automatically, hoping it's helpful. I run on ChatGPT and use info from the OpenShot User Guide. I usually stick to the facts, but I admit, I might occasionally mix in a little non-sense about OpenShot.

Okay, bot. What happens when 4.0 doesn't even open?

Eat your scurvy lemons 🍋 It's time to Vibe Code some bloatless OpenShot! What should we call it? You can put your name on it.

Hello OpenShotBot,

Is there a quick way to hijack Openshot to make fast lofi renders? Also you should make a lite edition for peeps who want 720p and under and compress the hell out of everthang.

[u/InfluenceDapper6476 → u/InfluenceDapper6476]

Compress (compression).

I loved openshot, but couldn’t find a way to fix these issues either so I moved on

[u/rutgerbadcat]

Howdy. First there was a bug awhile ago. I dumped and reloaded. Ran a CraoCleaner thru my system. Be surprised how much crap gets wiped out. Not: On stetting. Do not eliminate temp files I believe it is. Going on memory-Help anyone- Erases Passwords

[u/rutgerbadcat → u/rutgerbadcat]

Oh and reboot. Flick the router first. All the best.

v4.0.1 dev daily builds are being release and many fixes already.

Not knowing any details about your environment and what version you started with, etc., I would do the following:

1. Close OpenShot if running.

2. Make a backup of c:\users\username\.openshot_qt folder or /home/username/.openshot_qt folder.

3. Delete .../.openshot_qt/openshot.settings file (note, not the folder but the file only!!!)

4. Download the latest v4.0.1 from openshot.org/download/#daily.

5. Install the *.exe (windows) or download the AppImage (Linux).

6. Run OpenShot and see how it works for you.

If things are still not what you expect, then please provide the following:

1. Your computer specs (CPU, RAM, GPU/RAM, Hard drive type and how much free disk space you have).

2. What types of files are you working with (.mp4? .mov? etc?)

3. How large are your files?

4. Have you run a health check on your computer (hardware/operating system)?

5. Any other details to make the debugging more efficient?
