I took my old NV-GS500 Panasonic camcorder; in order to finally turn all our recordings into digital media.
So far, things worked easily:
- On Ubuntu 16.04; I just had to connect the device and my laptop; via the DV/firewire cable
- Just using the standard settings (I didnt select any output format; just went for "single" unlimited file) ... kino created a capture.dv file for me
- That created a ~8 GB file for 40 minutes of video ... ok with me
- I then used a little script that reads does
ffmpeg -i infile -pix_fmt yuv420p -crf 23 outfileto turn that dv file into an mp4
But alas, the quality of the mp4 isn't that convincing. Especially on rapid movements, lots of pixelish stuff.
Thus, I want to improve the whole thing. And as now discovered that kino is actually "dead"; I am wondering what combination of tools gives me good quality; as easily as possible.
Update: the full command for ffmpeg is already given above, here is the output I am receiving when running that:
> ffmpeg -i capture001.dv -pix_fmt yuv420p -crf 23 test.mp4

It is well worth running a deinterlacing video filter during your video encode and this may very well lessen some of the odd screen effects that you are seeing in your output video. A second thought, unrelated to motion artefact but well worth adding in, is the use of a de-noising filter.
1. Deinterlacing:
For FFmpeg the best and fastest choice is
yadifwhich in the usual quirky geek fashion simply stands for 'Yet Another DeInterlacing Filter'!yadifcan be used with no options or you can specify an option for each of 3 fields:The safe defaults can be specified on the FFmpeg command line as:
If you wish to alter these all of the deeper detail is contained here:
FFmpeg Filter Documentation: yadif
https://ffmpeg.org/ffmpeg-filters.html#yadif-1
A further deinterlacing filter called
mcdeint(motion-compensation deinterlacing) can also be applied but you may find this painfully slow. A typical command line for use of this filter would be:And again the fine detail of the
mcdeintoptions can be seen in the FFmpeg documentation:FFmpeg Filter Documentation: mcdeint
https://ffmpeg.org/ffmpeg-filters.html#mcdeint
2. Denoising:
A final though that may well be worth some experimentation is the use of a denoising filter, although this should not effect motion artefact it is still a well worth addition. Under FFmpeg there are a few choices but one well worth looking at is
nlmeans(denoise frames using Non-Local Means algorithm). You will need the very latest FFmpeg for this one.To use this in the easiest command line try the following:
There is a hit with
nlmeansin terms of encoding time, not as severe a penalty as is seen withmcdeintbut still a consideration...If you have an older copy of FFmpeg with no access to this newest filter there is an older denoise filter that can safely be used with trust in the sane defaults:
I note on my own system that
hqdn3dis very, very much faster than the newernlmeans. Better? Well I suspect that is a debate for another forum :)And hopefully a combination of any of these thoughts will solve your problem...
References:
You can quickly and easily achieve very good quality using Handbrake app. Install it with:
I suggest you encode to x264, it's currently most commonly used coded and you can have quite small file while preserving good quality. For private archive I recommend setting up Constant RF (rate factor) to between 16 and 18 (lower = higher quality and larger size).
If your video is noisy (it's probably is), there's also very neat denoise filter:
You might also need to deinterlance your source. As for audio... 320 kbps MP3 or AAC should give great results for personal archive. Everything can be set in Handbrake's GUI.
