How to digitize old VHS videos with an EasyCAP UTV007 USB converter on Linux

2018: VHS is dead! If you don’t have a functioning VHS player any more, your only option is to buy second-hand devices. But if you still have old, valuable VHS videos (e.g. family videos) you should digitize them today, as long as there are still working VHS players around.

Our goal is to feed the audio/video (AV) signals coming out of an old VHS player into an EasyCAP UTV007 USB video grabber, which can receive 3 RCA cables (yellow for Composite Video, white for left channel audio, red for right channel audio).

VHS players usually have a SCART output which lucklily carries all the needed signals.

Via a Multi AV SCART adapter you can output the AV signals into three separate RCA cables (male-to-male), and from there into the EasyCap video grabber. If your adapter should have an input/output switch, set it to “output”.

The EasyCAP USB converter uses a UTV007 chip, which is supported by Linux out-of-the-box. (Who said that installing drivers is a pain in Linux???) After plugging the converter into an USB slot, you should get two additional devices:

  1. A video device called “usbtv”
  2. A sound card called “USBTV007 Video Grabber [EasyCAP] Analog Stereo”

Too see if you have the video device, run v4l2-ctl –list-devices . It will output something like:

usbtv (usb-0000:00:14.0-7): 
       /dev/video0

To see if you have the audio device, run

pactl list | grep -C 50 'Description: USBTV007'

It will output something like:

To quickly test if you are getting any video, use a webcam application of your choice (e.g. “cheese“) and select “usbtv” as video source under “Preferences”. Note that this will only get video, but no audio.

We will use GStreamer to grab video and audio separately, and mux them together into a container format.

Install GStreamer

To install GStreamer on Debian-based distributions (like Ubuntu), run

apt-get installgstreamer1.0-tools gstreamer1.0-alsa gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly

Test video with GStreamer

Now, test if you can grab the video with GStreamer. This will read the video from /dev/video0 (device name from v4l2-ctl –list-devices above) and directly output in a window:

gst-launch-1.0 v4l2src device=/dev/video0 ! autovideosink

Test audio with GStreamer

Now, test if you can grab the audio with GStreamer. This will read the audio from the ALSA soundcard ID hw:3 (this ID comes from the output of pactl list above) and output it to PulseAudio (should go to your currently selected speakers/headphones):

gst-launch-1.0 alsasrc device="hw:3" ! pulsesink

Convert audio and video into a file

If both audio and video tested OK separately, we now can grab them both at the same time, mux them into a container format, and output it to a file /tmp/vhs.mkv. I’m choosing Matroska .mkv containing H264 video and Ogg Vorbis audio:

gst-launch-1.0 -e \
matroskamux name="muxer" ! queue ! filesink location=/tmp/vhs.mkv \
v4l2src ! queue ! x264enc ! queue ! muxer. \
alsasrc device="hw:3" ! queue ! audioconvert ! queue ! vorbisenc ! queue ! muxer.

Record some video and then press Ctrl+C. The file /tmp/vhs.mkv should now have audio and video.

It would be nice if we could see the video as we are recording it, so that we know when it ends. The command below will do this:

gst-launch-1.0 -e \
matroskamux name="muxer" ! queue ! filesink location=/tmp/vhs.mkv async=false \
v4l2src ! tee name=mytee \
mytee. ! queue ! x264enc ! queue ! muxer. \
mytee. ! queue ! autovideosink \
alsasrc device="hw:3" ! queue ! audioconvert ! queue ! vorbisenc ! queue ! muxer.

You also can re-encode the video by running it through ffmpeg:

ffmpeg -i vhs.mkv -vb 700k -ab 100k seekable-vhs.mkv

You can adjust the video and audio bitrate depending on the type and length of video so that your file will not be too large. The nice side-effect is that the coarser the video encoding, the more of the fine-grained noise in the VHS video is smoothed out.

Voila! You now should be able to record and archive all your old family videos for posterity!

  1. Thank you for the great write up.

    I was able to make the video seekable by setting the -e flag

    gst-launch-1.0 -e …

    -e, –eos-on-shutdown
    Force an EOS event on sources before shutting the pipeline
    down. This is useful to make sure muxers create readable files
    when a muxing pipeline is shut down forcefully via Control-C.

    For me I also added a queue to the video before the muxer in order to make the output smooth.

  2. Thanks! This is how I got my Video Grabber working in Kubuntu 16.04

  3. I’ve looked online and there are a lot of fake devices advertised as UTV007 chipsets. Please share the link where you have bought the device. I would like to ensure I am not buying crap 🙂

  4. Hello Michael,

    Thanks for the article, great stuff.

    Please let me know where you bought the UTV007 adapter. A link would be greatly appreciated.

    Thanks

    Hi, with your commands my Laptop (4 cores, LinuxMint 18) got to overload after 20 min of converting resulting in standing pictures. With the following command I succeeded:
    gst-launch-1.0 -e matroskamux name=”muxer” ! queue ! filesink location=vhs.mkv async=false v4l2src device=/dev/video1 ! tee name=mytee mytee. ! queue ! x264enc rc-lookahead=10 tune=zerolatency speed-preset=6 ! queue ! muxer. mytee. ! queue ! autovideosink alsasrc device=”hw:1″ ! tee name=mytee1 mytee1. ! queue ! audioconvert ! queue ! vorbisenc ! queue ! muxer. mytee1. ! queue ! pulsesink
