AVI to DIVX - LARGE file!

[Baltazar]

I wanted to capture some stuff from my VCR with iuVCR.

Theese are my settings:
* Video/Format: 640x480 - Video/Compression: UYVY
* Video/Compression: PICVideo MJPEG Codec
* Video/Set custom video format: 640x480 - UYVY - YUV 4:2:2 interleaved
* Capture/Settings: Frame rate 25.000 (PAL)

I'd like to capture in 640x480 since I'm going to make an DivX .avi

So far so good.......!

Settings when encoding the AVI to DIVX in VirtualDUB:
* Video/Full processing mode
* Video/Compression - DivX Pro 5.0.5 codec - Encoding bitrate 780kbps.

The problem is that the encoded file is huge - 16mb/minute!

I had hopes to have 1½hour on a 700mb CDR...

Can someone help me please.

Why not use TMPGEnc to adjust the bit rate in Settings, then select File-->Output to File...AVI, and select the DivX codec. I am thinking if the video is less than perfect, you may also try AviSynth to open the file in TMPGEnc.

[Baltazar]

I get no sound when doing it in TMPGenc - Output to file AVI file, and yes, I choose Audio and Video source as the same file.

The size of the file radically dropped though - to 6mb/minute...

How come, when I'm using the same coded as in VirtualDUB (DivX 5.0.5)

[Tommyknocker]

Why not save the audio out as a different file? Use Virtual Dub mod, or Gold Wave

[Baltazar]

Too much work! There must be an easier sollution..

[Tommyknocker]

No. Funny thing about work, it can take some time. Hope you do find an answer you are willing to try.

[Baltazar]

Either way if I separate my AVI file with an audio file the DivX file won't be smaller anyway so your advice isn't helping me

[Tommyknocker]

Of course it will when you adjust the bit rate to a lower value, your file will take up less space.

[feenix]

You didn't actually mention if you were compressing your audio or not? If you're not that will make a huge difference in file size. It could explain why your Tmpgenc file (with no audio) is way smaller that the Vdub file at the same bitrate.

Just a thought

[Baltazar]

So what audio compression should I set in iuVCR when capturing? - MPEG Layer-3?

Attribut? - 44100 Hz, 128kpbs CBR, Stereo?

[Baltazar]

...And should i use any filters?

It's an old camrecorded VHS which I'm capturing and there are a lot of thin horizontal lines when watching the captured files. Maybe it's impossible to do anything about? Maybe it's because that 20 year old "bad" camrecorder?

[Baltazar]

Solved it with the horizontal lines... I added filter deinterlace (blend) and the lines was almost gone

Shouldn't there be a guide here of how to make a DivX? (Maybe there is?)

Just one more problem, there are black borders left and right of the picture, can I strech the image when encoding it to fit the whole screen?

[Gazorgan]

This isn't hard.

Don't compress to mp3 with iuvcr, it has issues, stay with PCM.

Nowhere in your responces did you say "Audio/Full Processing, MP3 44khz 128 kbps, stereo". 90 minutes of pcm audio will take up about 1.2 CDR's (it's an 80 minute CDR, think about it). We are talking 1 GB.

#2, you have a low video bitrate for that high a resolution @25 fps.

#3 DivX are generally de-interlaced, since it's mostly computer only to view then, and computers don't like interlaced video.

The image will fit your screen if you tell you player to go full screen. However, we are getting into aspect ratios now, and whether or not to maintain them.

[Baltazar]

"Don't compress to mp3 with iuvcr, it has issues, stay with PCM."

- I noticed, hmmmm, the sound became out of sync after a while, is it because of the mp3 conversion or should I check the Options/Sync using stream offset? Or should I stay with PCM when capturing and then when encoding using TMPGEnc choose Audio/Full processing mode and choose MPEG Layer-3?

"#2, you have a low video bitrate for that high a resolution @25 fps."

- What bitrate should I use then?

"#3 DivX are generally de-interlaced, since it's mostly computer only to view then, and computers don't like interlaced video."

- Yes, so I'll go for deinterlacing it then, is it possible to convert the DivX files to SVCD later if I'd like so when the DivX files are deinterlaced?

"The image will fit your screen if you tell you player to go full screen."

- It doesn't fit my screen when I go full screen, still black stripe both on left and right side of the picture.

Crop it out

[Baltazar]

Öh?

[Baltazar]

Except for the deinterlace filter in VirtualDub I added the Null transform filter aswell with 512x480 (I cutted out 64 both on the left and right side).

Is this the correct way to do it?

When watching the encoded clip in the Windows media player (fullscreen it covers the whole screen correctly). But when playing the clip in the DivX player it has even wider black borders left/right side of the picture if I do not choose TV aspect 4:3, is this correct? Do I always have to choose TV aspect 4:3 instead of leaving at Original aspect when watching the movie fullscreen, or is it wrong by me using the Null transform filter and crop the movie to 512x480?

[Baltazar]

...Or should I go for 640x352 as I've seen other DivX's formats being, and if so, how do I do it? Also with the Null transformation filter?
