[SOLVED] Dazzle 100 101 Analog-Digital Conversion

Tools → Preferences → (Show Settings - All) → Input/Codecs → Demuxers →

It actually says “Demux module”

I get this far but there is no “Force Index Creation” in the drop-down.

There is an “AVI Demuxer” option and when selected no further step is offered - neither is one offered after Save.

When you get to Demuxers expand the category (in the left hand pane) and you should find AVI in the drop-down list

Is there a way to compress it without doing harm or are AVI files always huge?

They are if you do not use the transcoding option.
You could try in VLC:

Media->Convert / Save->Capture Device:
Set it up as previously

Click Convert / Save
Add destination file
->Settings->Profile
If required (or just select from pre-built):
->Create new profile (adjust to suit)
Name = Video - AVI
Encapsulation = AVI
->Video codec
Video (tick)
Codec = MPEG-4
Bitrate = 8000 kb/s
->Audio codec
-Audio (tick)
-Keep original audio track (tick)
-Save

Select profile Video - AVI

Press Start button to begin.

I personally prefer to capture without transcoding (storage space permitting) as my machine is not quite up to transcoding on the fly.
I would then use another transcoding program to reduce the file size.

Got it, thanks!

I was hoping someone would get OpenShot 1.43 compiled for Puppy Linux LH64-602b but they want to wait for v2.0 (due in December) since it’s a major rewrite. (Compiling an app like that is way over my head.)

I have previously tried Avidemux without good results.

What Linux-friendly video editor would you use post-conversion (via the steps you have been leading me through with VLC) to reduce the file size?

Perhaps it’s already in the repository LH64 uses …

Arista
or
WinFF

I will see if Arista is available for this 64-bit setup.

I also just noticed that a “transcoder ffmpeg frontend” that Help → About identifies as “Transcoder 0.0.5” is preloaded.

Anyone familiar with using it for this purpose, please?

I tend to use FFmpeg or mencoder on the command line to reduce the file sizes.
You could try:

ffmpeg -i input.avi -c:v mpeg4 -vtag xvid -qscale:v 6 -c:a libmp3lame -qscale:a 4 output.avi

Change the -qscale:v 6 to lower value to get higher bit rate (file size) or to higher value to get lower bit rate (file size)
A change of 6 will double or halve the resulting bit rate.

YOU are amazing and THAT is amazing!

FROM: 11G

TO: 242M

I can see some degradation in quality & loss of audio but it’s marginal for the value-added of reduced size.

Thanks!

We can call this one SOLVED++

See … I knew it :wink:

See .. I knew it ;)

Lucky draw, I guess :stuck_out_tongue:

@HandyGeek
If you are concerned with the audio then you could change it to say -qscale:a 2
Audio does not add much to the file size, so you could up the bitrate by reducing the -qscale:a parameter.

Did you know that if you go to the first post you can edit the title to add SOLVED as instructed here:

Thank you re. tweaking the audio level without significant increase to the file size.

[SOLVED] now precedes the Subject.

Sure appreciate the assist - I hope many will benefit from this - I imagine used Dazzle devices may be in sudden demand. ;D
