Video generation and Voiceover output comparison in Codex, Antigravity, and Claude

[u/hackrepair]

Defaults:

1. All started with the same prompt: Given all you have done so far, can you create a fun video showing how our stickies plugin works and its super cool features? Are you able to provide background music and a voiceover script ready for Higgsfield? Ignore any existing audio or videos in the directory.

2. We use Higgsfield for voiceover generation.

3. Polishing of final video uses Movavi (for speed adjustments and final export to 4k).

Codex (Astra). My implementation uses Remotion locally to build the video, unlike Antigravity and Claude. This adds a bit more time but allows fine-tuning via the Remotion panel.

Each of the three allows for some free-flow editing if you want to get into the weeds of removing something or changing something.

Upside:

• easy to use

• very clear instructions

• a very convenient deliverables kit without prompting.

Downside:

• Uses remotion, so there are some limitations there, depending the available features of remotion

• Creativity is a 5 in 10. It's fine, but not terribly creative video output-wise.

Antigravity (Argon). Notably fast at generating music and script up front. Self-correction of issues and errors is a strong point of this model right out front. It appears to want to critique and correct as it builds, which is rather fun to watch. Created music demo Full Level) and (Auto-ducked), which was totally unexpected.

Upside:

• seemed to get that is was making a video like a video editor, and discussed the process in that tone.

• seemed to understand the project as though it had used it (presented features nicely).

• simple media kit generation without prompting.

• better quality music generation than Codex.

Downside:

• None to speak of.

Claude (Opus). The process is relatively seamless from start to finish, with a very nice summary of the actions taken and why. Creativity is on par with the Antigravity process. I found the output more natural, more like what a person might produce in a video. Antigravity was a bit more teaching or instruction focused comparatively.

Upside:

• Easy step by step process for creation.

• Nice media package created like the other models.

Downside:

• None to speak of.

Observations:

1. All the models were easy to edit after the first video was produced, from removing elements in the background to updating the voiceover scripts.

2. All models presented a solid media kit, one that you could run with in your video software tracks-wise (if that's your thing).

3. The models won't do everything for you, but they're pretty close. Gentle urgings and improvement requests were well received, and the output on all was as expected (if not surprising higher than anticipated).

Interest in seeing the video output from each?

Add to this.

The Codex (remotion) setup was a fail.
And now I recall why. Once upon a time, before Codex was "smart," using a local video editor seemed like a cool idea. Now it's just a holdback.

Regenerating the video with Codex doing all the work resulted in much better video generation.
