FAQPage Schema

How do I extract media files from Bitcoin SV transactions?▼

Extract media files from BSV transactions using txex with an outpoint identifier. The tool auto-detects filenames and file extensions, pulling images, video, and audio directly from the blockchain with a single command like `txex <outpoint>`.

Can I resize and convert images or video extracted from the blockchain?▼

Yes, txex applies media transforms to resize, convert formats, and process images, video, and audio. Specify width with `-w`, output format with `-f`, and output filename with `-o`, such as `txex <outpoint> -w 800 -f webp -o thumb.webp`.

What do I need to transform media with txex?▼

Transforming media with txex requires ffmpeg installed on your system. The tool uses ffmpeg to resize, convert, and apply transforms to images, video, and audio extracted from Bitcoin SV transactions.

How do I download entire NFT collections from the blockchain?▼

Download entire NFT collections from BSV using txex with a collection outpoint and a limit flag, such as `txex <collection_outpoint> --limit 50`. Results are cached locally for repeated fast access.

Does txex support different blockchain media protocols and standards?▼

txex supports B://, BCAT, 1Sat Ordinals, and ORDFS Streams for extracting media from Bitcoin SV. The tool handles multiple protocol formats in a unified extraction and caching workflow.

Where does txex store extracted and transformed files?▼

txex uses a two-tier cache at ~/.txex/cache/ with raw transaction data stored under tx/ and transformed outputs cached separately. This structure accelerates repeated extractions and transformations.
