How to convert a file in VLCExcerpt from a converted ASF archive
Download exampleArchivist: Is this the recording from the morning session? Coordinator: Yes. The opening is missing, but the speaker introductions start about two minutes in. Archivist: I’ll label the transcript as a partial recording.
How it works
Convert, then upload
Convert the original to MP4. Then open Speechyou Notes, select Upload, and choose Upload & transcribe.
Review the transcript
Open the finished note and check the text against the recording. Use Edit transcript to correct names, terminology, or misheard words.
Export Text (.txt)
Open Export in the transcript and choose the file type. Save the file or share it with your team.
Transcription guide
Check that the ASF file holds a recording
Advanced Systems Format files can contain audio, video, or both. A small shortcut or playlist from an old Windows Media site may only point to the source. Locate the actual saved media and open it in a player before choosing an export format.
Choose an export based on the available streams
For video with speech, make an MP4 with the intended audio stream. For an audio-only ASF, export PCM WAV and use the WAV transcription workflow instead. Keep the original copy and confirm the duration and audio of whichever export you make.
Use the transcript to recover the spoken material
Check phrases around cuts or gaps in the source, which are common in older streaming archives. If another archive has a higher-quality copy, use it to verify hard-to-hear words. Save the revised transcript beside the source with the same name or collection identifier.
Mark missing material in a partial Windows Media recording
If the file opens partway through a speaker’s introduction, check whether the archive has a complete second copy before converting. When only the partial recording is available, note the missing section in the transcript title or the archive record. Preserve the timestamps within the converted file and record any known offset to the full event separately. This lets a researcher trace quotations to the playable source and avoids confusing an opening that was absent from the recording with a passage missed by transcription.
Check an ASF archive file
- Locate the actual media file if you received an ASX playlist or an old streaming link.
- Play the ASF and determine whether the recording includes video.
- Export MP4 for video with speech or PCM WAV for audio-only material.
- Check playback and duration before uploading the converted file.
Frequently asked questions
Is ASF the same as WMV?
ASF is a container used by Windows Media. A .wmv file commonly uses an ASF container for its video. Either legacy extension needs a supported export before uploading to Speechyou.
Can I transcribe ASF with audio only?
Export a PCM WAV from the playable audio-only ASF, then upload the WAV in Speechyou Notes.
Can I use an old .asx playlist as the source?
Find the saved audio or video recording referenced by the playlist and make a supported MP4 or WAV export from that file.
