Best syntax for camcorder videos for video editing?

linuxuser · Post by **linuxuser** » Fri Jan 13, 2012 3:10 pm

I would like to prepare a camcorder-dv-file for video-editing and "adjust" a few things before I load the file into a movie editor. Mainly I like decomb to deinterlace and I would like to remove these aspect-ratio things, mainly PAR and use square pixels. Filesize doesn't count.

So please help me to improve this command, to get the best quality possible.

Code: Select all

HandBrakeCLI -i dvtest.avi -C 1 -e x264 -q 16 -a 1 -E lame -B 320 -R 44.1 -D 0.0,0.0 -f mp4 --decomb --loose-anamorphic -m -x b-adapt=2:rc-lookahead=50  -o movie.mp4

--loose-anamorphic is a placeholder, since I know a better solution.

-C 1: creates maybe a better quality, if 1 CPU is used. Since there are thousands of small files, multi-threading is not an advantage, since I can run 2 files with 1 CPU at the same time, maybe the cpu is better used then too

-e x264: my codec taste

-q 16: as said, quality counts, size not and the file will be used in a movie editor and be calculated again

-a 1: 1 Audio stream is enough, but I don't know how I can select the better audio stream. Please see at the end. Does the dv-file contain the audio 2x with the same quality?

-E lame -B 320: don't know if there is an option for a better quality? I didn't find out if flac can be used

-R 44.1: I would like to mix the camcorder-sound with mp3s, so I upsample the camcorder sound to 44.1

-D 0.0,0.0: no crop, but maybe used with 4:3 videos

-f mp4: I think it is not important if mp4 or mkv is used. I use mp4, because the result will be in mkv, so I can see easily that mp4 is an input file

--decomb: I think the best way to deinterlace dv-files?

--loose-anamorphi: I am very unsure, what to use here and I think I want to have anamorphic off and PAR=1

-m: I think not necessary, since markers are not used, but not wrong too

-x b-adapt=2:rc-lookahead=50: default of the high profile, improvements for dv are welcome.

With the mentioned command line I get a 1.4MB mp4-file from a 14MB dv-file. This is a lot saving, I don't care if the files get larger and the source quality would be (theoretically) better then for video editing.

Not really. According to Dark_Shikari (lead x264 developer), threads should be useful and the quality hit should be minimal up to height/40 threads (in this case, 576/40 = 14 threads). Though if you have many many files you could also run 14 instances…

linuxuser wrote:-a 1: 1 Audio stream is enough, but I don't know how I can select the better audio stream. Please see at the end. Does the dv-file contain the audio 2x with the same quality?

Judging by the MediaInfo output below, both audio tracks are identical, so it makes no difference which one you pick (1 or 2).

linuxuser wrote:-E lame -B 320: don't know if there is an option for a better quality? I didn't find out if flac can be used

In the nightly build (see the announcement at the top of every subforum). But it can't be muxed in MP4 containers, and I doubt many video editing solutions support either MKV or FLAC.

linuxuser wrote:--decomb: I think the best way to deinterlace dv-files?

The defaults may be a bit weak for fully interlaced material - the nightly builds features new, stronger default settings which should work better.

linuxuser wrote:--loose-anamorphi: I am very unsure, what to use here and I think I want to have anamorphic off and PAR=1

The CLI default is anamorphic off (PAR=1/1). Do not specify any anamorphic option, and specify width and height.

linuxuser wrote:-m: I think not necessary, since markers are not used, but not wrong too

If the source has no chapters, chapter markers will not be added to the output regardless of the option.

I tried flac with the GUI and the file woks then with kdenlive, but I didn't find out the syntax for flac. https://trac.handbrake.fr/wiki/CLIGuide doesn't mention it, probably the feature is too new. I use the Ubuntu-Unstable-Repo with HandBrake 4394svn 2011123101

I tried it without --loose-anamorphic and without a dimension, and mediainfo tells me 720x576, while vlc plays it with 1024x576, I guess.

I tried it with -w 1024 -l 576 and I get 1024x816.

What I am doing wrong?

Which options do you recommend for decomb and how is the syntax?

The encoder name is ffflac (see HandBrakeCLI --help).

Don't know what the Ubuntu-Unsatble repo is, but unofficial builds are not supported. You can find official Ubuntu nightlies on LaunchPad:

Full CLI command + Activity Log please (with the CLI, that would be the stderr output).

The defaults (just --decomb), as of the nightly builds.

linuxuser · Post by **linuxuser** » Sat Jan 14, 2012 12:25 pm

In this case I use:

Code: Select all

cat /etc/apt/sources.list.d/handbrake_snapshot.list
deb http://ppa.launchpad.net/stebbins/handbrake-snapshots/ubuntu oneiric main

But I use the Packman-Version with Opensuse too.

I changed the syntax a little bit, and today it worked, so I guess, it depends which options are first.

Code: Select all

HandBrakeCLI -i dvtest_001_20100216214015.000-720x576i-169-25fps-dv1-32khz-4s40ms.avi -C 1 -e x264 -w 1024 -l 576 -q 12 -a 1 -E ffflac -R 44.1 -D 0.0,0.0 -f mkv --decomb -m -x b-adapt=2:rc-lookahead=50  -o movie.mkv

In the meantime I read
http://comments.gmane.org/gmane.comp.vi ... evel/58452
H.264's quantization parameter (QP) is on a logarithmic scale.
The mapping is approximately H264QP = 12 + 6*log2(MPEGQP).
For example, MPEG at QP=2 is equivalent to H.264 at QP=18.
+Generally, this option should be avoided and crf should be used instead.

So I guess, crf=12 should be a good approach to lossless. I am not talking of a visible difference compared to higher crf, but of a base for a video editor. In a video editor like kdenlive or openshot filters are used, which are not available in handbrake, on the other side, the video editor doesn't offer filters like decomb.

I post the complete log below, because maybe you see something, that I don't recognize as problem.

This looks fine, though you're setting FLAC compression to 1 (least compression) when it shouldn't make any difference to encoding speed (video encoding would be the bottleneck here), when compared to the default (5).

Also, from this log the video is clearly being converted successfully to 1024x576 square pixels.

Thanks a lot for looking into it. How to i get the highest flac compression?

ffflac - c 8 ?

HandBrakeCLI --help is not clear for me. With "-c 8" it is ended immediately.

Options are case-sensitive…

Note that the default compression level (5) should not introduce any noticeable speed hit, but I haven't tested with 8, 10 (highest compression level that's "FLAC subset compliant") or 12 (highest compression level).

I know, but now I am confused, probably because of using https://trac.handbrake.fr/wiki/CLIGuide and --help. At https://trac.handbrake.fr/wiki/CLIGuide I see

-C, --cpu Set CPU count (default: autodetected)

If I use --cpu I get: unrecognized option '--cpu'

So I understand, why I get "compression level: 1.00" with -C 1.

So how can I tell handbrake to use 1 cpu only?

Deleted User 11865 · Post by **Deleted User 11865** » Sat Jan 14, 2012 2:52 pm

Oh, right. The --cpu option was removed. If you want x264 to only use 1 thread, you need to add threads=1 to your advanced x264 options (-x).

linuxuser · Post by **linuxuser** » Sat Jan 14, 2012 4:02 pm

I think finally I have an acceptable solution, which works with kdenlive and openshot. I tested the preview of a very short clip only and I could see an image and hear the sound.

The advantage of using Hanbrake before the video editor is to use --decomb to deinterlace the video, if necessary, without checking if it is interlaced or not and to get square pixels, so there is no need to think about if anything in the queue, normally the TV or media player is distorting the picture, because of a wrong interpretation of PAR.

Original file size of the camcorder file: 14M
Handbrake-File:5.5M

Interesting is, the filesize is the same without -C 8, that is -C 5, the default compression, maybe because the clip is very short.

Depending on the importance of the sound, lame could be used. With -B 320 the file gets 5.3M, so I think for important personal movies the difference between best lame options and flac doesn't count, on the other hand camcorder sound from the built-in microphone is normally very bad.

I tried flac with a 523M mpg-file, the size is nearly the same with -C5 and -C 8.

I agree that the quality was too high, but I am talking of the compression of flac.

Code: Select all

1188284347 2012-01-14 17:57 movie5.mkv (.C 5)
1187764401 2012-01-14 17:57 movie8.mkv (-C 8)

Is this possible?

Yes. The FLAC compression level only affects the size of the output by a few percent (less if you compare two compression levels that are close). Which is why you might as well use the default.

I saw there is a misunderstood option by me; -D 0.0,0.0. This is nonsense with 1 audio-stream. I don't understand "-D 0.0" too, is this default? What is a recommended value for a camcorder?

It only affects AC3 audio source tracks. You can just leave it out.

linuxuser wrote:-a 1: 1 Audio stream is enough, but I don't know how I can select the better audio stream. Please see at the end. Does the dv-file contain the audio 2x with the same quality?

-E lame -B 320: don't know if there is an option for a better quality? I didn't find out if flac can be used

According to your post the source audio is 12bit 32KHz stereo, which is MUCH lower quality than CD. Personally I wouldn't bother FLACing a source with that low of a detail level. In your case I would just use a low bitrate MP3 or Vorbis transcode....no point in turning up the bitrate to 320Kbps as again the detail level is way below that of a CD. Even setting Lame to 128Kbps would in all likelyness still be overkill in this case.

linuxuser · Post by **linuxuser** » Sun Feb 05, 2012 9:57 am

I use FLAC in the meantime. "-E lame -B 320" should be a setting which fits for better quality too. I decided to create a simple option file in the sourcefile-dir, which allows individual settings

example of an option file:

Code: Select all

X264QUALITY=23
AUDIOENCODER=lame -B 192
CROP=64:108:24:22
WIDTH=768
HEIGHT=432
FILTER=--decomb  --denoise

There are a lot of other individual and personal things, which I do, mainly renaming and checking for broken files, which lead to a different number of source and recoded files, but the following is the mainpart. Maybe it is for others an idea for an own script. Note: a video length of about 0.3 sec results in a broken file. I do not recommend to recode all the files with handbrake without looking at the logs. From time to time there can be clips with problems, which you don't expect, mainly because the sourcefile is somehow broken.

Code: Select all
