## Summary
- Add asymptotic progress bar that appears during long-running chat
tasks
- Progress bar shows after 10 seconds with "Working on it..." label and
percentage
- Uses half-life formula: ~50% at 30s, ~75% at 60s, ~87.5% at 90s, etc.
- Creates the classic "game loading bar" effect that never reaches 100%

## Test plan
- [x] Start a chat that triggers agent generation
- [x] Wait 10+ seconds for the progress bar to appear
- [x] Verify progress bar is centered with label and percentage
- [x] Verify progress follows expected timing (~50% at 30s)
- [x] Verify progress bar disappears when task completes

+
+## Add Audio To Video
+
+### What it is
+Block to attach an audio file to a video file using moviepy.
+
+### How it works
+<!-- MANUAL: how_it_works -->
+The block uses MoviePy to combine video and audio files. It loads the video and audio inputs (which can be URLs, data URIs, or local paths), optionally scales the audio volume, then writes the combined result to a new video file using H.264 video codec and AAC audio codec.
+<!-- END MANUAL -->
+
+### Inputs
+
+| Input | Description | Type | Required |
+|-------|-------------|------|----------|
+| video_in | Video input (URL, data URI, or local path). | str (file) | Yes |
+| audio_in | Audio input (URL, data URI, or local path). | str (file) | Yes |
+| volume | Volume scale for the newly attached audio track (1.0 = original). | float | No |

+| video_out | Final video (with attached audio), as a path or data URI. | str (file) |

+### Possible use case

+- Adding background music to a silent screen recording

+## Video Clip
+
+### What it is
+Extract a time segment from a video
+
+### How it works
+<!-- MANUAL: how_it_works -->
+The block uses MoviePy's `subclipped` function to extract a portion of the video between specified start and end times. It validates that end time is greater than start time, then creates a new video file containing only the selected segment. The output is encoded with H.264 video codec and AAC audio codec, preserving both video and audio from the original clip.

+
+### What it is
+Merge multiple video clips into one continuous video
+
+### How it works
+<!-- MANUAL: how_it_works -->
+The block uses MoviePy's `concatenate_videoclips` function to join multiple videos in sequence. It supports three transition modes: **none** (direct concatenation), **crossfade** (smooth blending where clips overlap), and **fade_black** (each clip fades out to black and the next fades in). At least 2 videos are required. The output is encoded with H.264 video codec and AAC audio codec.

+# Video Duration
+<!-- MANUAL: file_description -->
+This block retrieves the duration of video or audio files, useful for planning and conditional logic in media workflows.
+<!-- END MANUAL -->
+
+## Media Duration
+
+### What it is
+Block to get the duration of a media file.
+
+### How it works
+<!-- MANUAL: how_it_works -->
+The block uses MoviePy to load the media file and extract its duration property. It supports both video files (using VideoFileClip) and audio files (using AudioFileClip), determined by the `is_video` flag. The media can be provided as a URL, data URI, or local file path. The duration is returned in seconds as a floating-point number.
+<!-- END MANUAL -->
+
+### Inputs
+
+| Input | Description | Type | Required |
+|-------|-------------|------|----------|
+| media_in | Media input (URL, data URI, or local path). | str (file) | Yes |
+| is_video | Whether the media is a video (True) or audio (False). | bool | No |
+
+### Outputs
+
+| Output | Description | Type |
+|--------|-------------|------|
+| error | Error message if the operation failed | str |
+| duration | Duration of the media file (in seconds). | float |
+
+### Possible use case
+<!-- MANUAL: use_case -->
+- Checking video length before processing to avoid timeout issues
+- Calculating how many times to loop a video to reach a target duration
+- Validating that uploaded content meets length requirements
+- Building conditional workflows based on media duration

+# Video Loop
+<!-- MANUAL: file_description -->
+This block repeats a video to extend its duration, either to a specific length or a set number of repetitions.
+<!-- END MANUAL -->
+
+## Loop Video
+
+### What it is
+Block to loop a video to a given duration or number of repeats.
+
+### How it works
+<!-- MANUAL: how_it_works -->
+The block uses MoviePy's Loop effect to repeat a video clip. You can specify either a target duration (the video will repeat until reaching that length) or a number of loops (the video will repeat that many times). The Loop effect handles both video and audio looping automatically, maintaining sync. Either `duration` or `n_loops` must be provided. The output is encoded with H.264 video codec and AAC audio codec.
+<!-- END MANUAL -->
+
+### Inputs
+
+| Input | Description | Type | Required |
+|-------|-------------|------|----------|
+| video_in | The input video (can be a URL, data URI, or local path). | str (file) | Yes |
+| duration | Target duration (in seconds) to loop the video to. Either duration or n_loops must be provided. | float | No |
+| n_loops | Number of times to repeat the video. Either n_loops or duration must be provided. | int | No |
+
+### Outputs
+
+| Output | Description | Type |
+|--------|-------------|------|
+| error | Error message if the operation failed | str |
+| video_out | Looped video returned either as a relative path or a data URI. | str (file) |
+
+### Possible use case
+<!-- MANUAL: use_case -->
+- Extending a short background video to match the length of narration audio
+- Creating seamless looping content for digital signage
+- Repeating a product demo video multiple times for emphasis
+- Extending short clips to meet minimum duration requirements for platforms

+# Video Narration
+<!-- MANUAL: file_description -->
+This block generates AI voiceover narration using ElevenLabs and adds it to a video, with flexible audio mixing options.
+<!-- END MANUAL -->
+
+## Video Narration
+
+### What it is
+Generate AI narration and add to video
+
+### How it works
+<!-- MANUAL: how_it_works -->
+The block uses ElevenLabs text-to-speech API to generate natural-sounding narration from your script. It then combines the narration with the video using MoviePy. Three audio mixing modes are available: **replace** (completely replaces original audio), **mix** (blends narration with original audio at configurable volumes), and **ducking** (similar to mix but applies stronger attenuation to original audio, making narration more prominent). The block outputs both the final video and the generated audio file separately.
+<!-- END MANUAL -->

+### Inputs
+
+| Input | Description | Type | Required |
+|-------|-------------|------|----------|
+| video_in | Input video (URL, data URI, or local path) | str (file) | Yes |
+| script | Narration script text | str | Yes |
+| voice_id | ElevenLabs voice ID | str | No |
+| model_id | ElevenLabs TTS model | "eleven_multilingual_v2" \| "eleven_flash_v2_5" \| "eleven_turbo_v2_5" \| "eleven_turbo_v2" | No |
+| mix_mode | How to combine with original audio. 'ducking' applies stronger attenuation than 'mix'. | "replace" \| "mix" \| "ducking" | No |
+| narration_volume | Narration volume (0.0 to 2.0) | float | No |
+| original_volume | Original audio volume when mixing (0.0 to 1.0) | float | No |
+

+
+### Possible use case
+<!-- MANUAL: use_case -->
+- Adding professional voiceover to product demos or tutorials

+# Video Text Overlay
+<!-- MANUAL: file_description -->
+This block adds customizable text captions or titles to videos, with control over positioning, timing, and styling.
+<!-- END MANUAL -->
+
+## Video Text Overlay
+
+### What it is
+Add text overlay/caption to video
+
+### How it works
+<!-- MANUAL: how_it_works -->
+The block uses MoviePy's TextClip and CompositeVideoClip to render text onto video frames. The text is created as a separate clip with configurable font size, color, and optional background color, then composited over the video at the specified position. Timing can be controlled to show text only during specific portions of the video. Position options include center alignments (top, center, bottom) and corner positions (top-left, top-right, bottom-left, bottom-right). The output is encoded with H.264 video codec and AAC audio codec.
