What changes when you convert VOB to F4V
This is a full transcode rather than a container swap, because MPEG-2 is not one of the codecs F4V carries. Every frame is decoded and re-encoded as H.264.
If the source has subtitles baked in as a separate track, they will not survive: F4V does not support embedded subtitle streams.
Alternate audio tracks are dropped, because F4V carries one audio stream where VOB allows several.
One practical gain here: F4V is streaming-friendly, so the converted file begins playing while it is still downloading.
Expect the bitrate to move from roughly 6.5 Mbps to about 6 Mbps at 1080p, and file size to follow.
About VOB to F4V Conversion
Converting VOB to F4V means moving audio out of the DVD-Video (MPEG-2 PS) container, introduced in 1996, and into Flash MP4, which arrived in 2007. The two were designed with different priorities, and that is what determines whether this conversion costs you quality, storage, or compatibility.
Developed by DVD Forum in 1996, VOB stores audio using MPEG-2. That codec choice sets the upper bound on what any conversion can preserve.
F4V, from Adobe and dating to 2007, uses H.264 and plays natively on 0 of the six platform categories we track. That combination is usually why people convert into it.
After converting your file, you can use Scriptivox transcription services to convert your audio to text. Perfect for meetings, interviews, podcasts, and more.
