Can you confirm the condition of your VHS tape player. I spent 3 months last year trying to work around this same problem only to find that the 20 year old tapes were the cause. Not correctable at least for me.

Here is the mencode script I used if it is any help

Code:

#! /bin/bash
## Rip analog tapes from camcorder to digital
## Sunday May 30, 2010
## Using Dazzle device

# check if there is no command line argument
if [ $# -eq 0 ]
then
echo "You forgot the required image name to be used!"
echo "Usage :: new image name"
exit
fi

mencoder tv:// -tv driver=v4l2:input=0:norm=ntsc:width=720:height=480:outfmt=yuy2:device=/dev/video1:forceaudio:audiorate=48000:adevice=/dev/dsp1 buffersize=128 -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=5000:keyint=30 -oac mp3lame -lameopts br=128:cbr:mode=3 -ffourcc divx -o "$1".avi

Tape player is about 4-5 y.o and with TV is working fine.
I will try your script next hours,thanks

Extension doesn't count

Dafydd · 03-24-2014, 05:01 PM

Extensions count when I go to that link and have to download an archived video and then do not have a program that will open it.

I don't have any experience with USB capture devices but I've done a few VHS captures with a PCI TV tuner that uses the bttv kernel module. My captures were done losslessly (huffyuv/flac) on a dual-core Athlon 64 X2 to a dedicated two-disk md software RAID 0 array followed by encodes with x264. I used tvtime for previews before recording and "qv4l2" to set the tuner settings, specifically "VCR hack" and "Full Luma Range". Alternatively these can be set using module parameters e.g.

Code:

modprobe -r bttv
modprobe bttv vcr_hack=1 full_luma_range=1

Keep in mind the following command line worked well a couple of years ago. A lot can change in that time so you may have to tweak it.

Code:

sudo nice -n -5 ionice -c 1 su -c 'schedtool -a 0x1 -e aoss avconv -f oss -ac 2 -ar 48000 -i /dev/dsp -f video4linux2 -s 768x480 -standard NTSC -pix_fmt yuv422p -re -channel 1 -i /dev/video0 -vsync 2 -vcodec huffyuv -acodec flac /media/raid500/testcapture.mkv' username

I haven't explored denoising or deghosting.
