Q: I have a bunch of .webm files (audio-only) saved on my hard drive. Is it possible to save the audio from WebM to Ogg without transcoding?
A: Well, the short answer is YES! Let me make a brief explanation. Both WebM and Ogg are free and open and royalty-free media containers. In addition to VP8, VP9 and AV1 video codecs, WebM also contains audio compressed with either Vorbis or Opus audio codec, while an Ogg file can contain both audio codecs, which makes it possible to convert WebM to Ogg without re-encoding. Next, let's dive into the details.
WonderFox HD Video Converter Factory Pro is an all-in-one video and audio processor designed to solve any A/V format incompatibility issue in a much easier way. Despite its featureless name, it's definitely a decent and efficient WebM to Ogg converter that allows you convert a heap of both WebM videos and audio-only WebM files to Ogg format in batch mode. You'll be impressed by its clean and straightforward layout. Now, free download this multi-purpose application and get down to the point.
Launch HD Video Converter Factory Pro and open "Converter" on a colorful main interface. Click "Add Files" or "Add Video Folder" button or just execute a simple drag-and-drop to import your WebM video or audio-only files. They will be listed in the workplace with basic video information after a few seconds. You're able to play each WebM file with the built-in media player by clicking each "Preview" button on the left side.
As you see, this handy utility is integrated with five main modules, apart from the "Converter", there are four additional modules "Downloader", "Recorder", "GIF Maker" and "Toolbox". Take this a step further if you get interested.
Press the Format Profile on the right side to open a full list of 500+ predefined presets grouped by common video/audio Formats and hot Devices. To extract Vorbis or Opus audio streams from WebM to Ogg format, navigate to "Audio" category and select Ogg profile without extra settings. Similarly, you can also convert WebM to FLAC, WMA, MP3, M4A and even video and device-compatible formats. If needed, this program also allows you to make a custom ringtone.
Let's go back to the question at the beginning of the article, to save the audio from WebM to Ogg without transcoding, you have to select the same audio encoder for Ogg format. Click "Parameter settings" button underneath the "Format Profile" to open a new window, where you can modify basic audio settings. Navigate to "Audio settings" section, select "Vorbis" or "Opus" option in the drop-down list of "Encoder". Click "OK" to save changes.
In addition, you're also allowed to change audio bitrate, sample rate, channel mode, and decrease/increase audio volume right there. To your surprise, this program is equipped with some basic editing features that enable you to cut, trim, split audio and splice music files together.
Once everything is finished, click the "Inverted Triangle" icon on the bottom to choose a destination directory to save the converted Ogg files. At last, press the big "Run" button to convert WebM to Ogg in batch mode.
That's all about how to convert WebM files to Ogg in batches.
