Confusion about DivX-Encoding settings

[foxhunter]

Hi,

the media player is connected via YrPrBr (YUV) cabling to the HDTV.

From my point of view, i don't see any differencies if i deinterlace the video first or send it to the TV directly. So i think i could leave it as it is.

Just use Staxrip, pick size/bitrate or do a 1 pass or 2 pass encode, Staxrip produces avi(divx) compatible files that can be played on any divx certified/xvid player.

It has deinterlacer and sharpness options, it even has a compressibility test like autogk if you're not sure which bitrate to pick.

Tools like avi.net, AutoGk or StaxRip were made having that in mind and have been thoroughly tested by "everyone" so that us (users) dont have to go through endless days finding what works.

I would recommend avi.Net but it doesnt accept avi/dv as input

Hi,

thanks for your reply. But if i don't need to deinterlace or sharpen the video, i just can do a fast compress via VirtualDub, isn't it?

Not if you're resizing vertically, you can't. Otherwise, why not try and see for yourself?

[foxhunter]

Yeah, good question.

I will try to create several files with identical compression but different deinterlacing and i will see what happens. I don't have to resize the files. I only want to make them compatible to my media player and save disk space without losing to much quality

By the way i have some other questions about virtualDub

1. What's the difference between Fast Compress and Normal Compress in the Video Settings?

2. If i capture my DV-Videos with VirtualDub, wouldn't it be better to set the compression format via capturing? Actually i have a DV-Video with 13 GB per hour. Wouldn't it be easier to do a direct XVid-Capturing?

Or isn't that possible in realtime?

1. What's the difference between Fast Compress and Normal Compress in the Video Settings?

Fast Recompress leaves the video in the colorspace (typically YUY2 or YV12) it comes from the source and passes it to the chosen encoder. Normal Recompress converts the source video to RGB then passes RGB to the encoder. Fast Recompress gives better quality.

2. If i capture my DV-Videos with VirtualDub, wouldn't it be better to set the compression format via capturing? Actually i have a DV-Video with 13 GB per hour. Wouldn't it be easier to do a direct XVid-Capturing?

You are more likely to drop frames if you compress while capturing. You would have to use Xvid at it's fastest settings (Reat-time quality preset) to do this. You won't get as good compression.

Thanks.

I forget the idea with compressed capturing

How about the colorspace, is it neccessary that this has to be changed?

If i check my source files, mediainfo tells me that the video is in a resolution of 24bits and the colormetric is 4:2:0

You should avoid colorspace conversion whenever possible. Use VirtualDub in Fast Recompress mode if you're not filtering.
