Can someone refresh my memory re resizing etc in VDM?

[AORMan]

I have an avi file which is 352x264 29fps, in size and I want to convert it to 720x567 25fps.

I know/remember about adding the resize filter, but what do I do after I have set the new sizes? How do I save the file and how do I process it?

Thanks

First - Crtl+R (or Video -> Framerate) and alter the framerate

Then

File -> Save As. From here you need to set the Video Mode to Full Processing, then click the Change button next to Compression. Select a codec, configure it, and save.

If you want mpeg2 then you need to go File -> Start Frameserver and send the video to your mpeg2 encoder.

However this is an ugly way to alter the framerate. Changing framerates from 29.97 to 25 fps is very difficult because you need to throw away frames to make it work. A much better idea is to resize to 720 x 480, leave the framerate as-is, and encode and author an NTSC disc/video (don't know if DVD is your end-game - assumption on my part)

The reason I want to convert to 720x576 @ 25fps is because I am in the UK and that is the general size for a PAL compliant DVD.

Most, if not all, DVD players sold in PAL countries (I am in Australia, another PAL country) will also play NTSC material without any problems. It is certainly not as easy to get a PAL capable player in NTSC land.

Personally, I would test out NTSC playback on your player before spending too much time on a poor quality conversion.

I would also look at What is DVD (top left corner of this page) and look at valid DVD resolutions. You won't gain much by resizing up to full PAL D1. I would look seriously at either NTSC VCD (352 x 240) or NTSC half-D1 (352 x 480)

Agreeing with gunslinger here....leave it.

Quick simple method :

1: Install avisynth
2: Install super
3: Open notepad , and paste this in it


AVISource("C:\your_video_clips_name_here.avi")
AddBorders(0,8,8,0)


4: As the script use's C:\ ... place your video clip in this location .
5: Now in notepad , save as ...
6: Change the "save as type" to "all files"
7: Save name = conversion.avs

Add the avs file extension ...

8: Save file location is C:\ ... same place where clip is .
9: Run super ... right click in box down below , and choose from popup menu the item at top of list "add multimedia file (s)

10: Chose your new avs file
11: Ouptut container = mpeg2
12: Audio output codec = ac3
13: Set super to use ffmpeg
14: Video scale = 352x288
15: Aspect = 4:3
16: Frame rate = 25
17: Audio defaults should be 48khz , 2 channel , 256kbps

18: Hit "encode" ... and wait .

----------------------

As the video is 352x264 ... it will have 8 lines of black added to top and bottom via the avisynth script , and super has been told the mpeg2 output size is 352x288 ... if this is not set , super will output at 720x576 .

Framerate is being converted ... not bang on , but close .

It is not being enlarged on the grounds that it would look like crap .

You can fit many of these clips onto a dvd ... or create a minidvd on cd using imgburn .

Under no circumstances ... do not use dvdshrink on these clips after dvd authoring to shrink to fit media ... it will stuff it completely ... from tests ... rejig is the only tool that will work properly should you need to reduce the final output prior to burning to media .

----------------------

Use batchdemux to demultiplex them ... found on dvdauthorgui download web page .

As for guns1inger " Most, if not all, DVD players sold in PAL countries (I am in Australia, another PAL country) will also play NTSC material without any problems"

Answer ... glad you said "most" ... because you can still get burnt with one that wont play nstc format .

A large majority of players in au , capable of outputing both format's do one thing well ... pal playback ... the quality of nstc is ... well I wouldnt even bother watching such rubbish .

Not blasting the format ... just the poor ability of a majority of player's inability to do both justice from the playback point of view ...

The issue usually isn't the quality of NTSC playback. These players will play back NTSC material as badly as an NTSC native player. The issue is that most are set by default to convert to PAL or PAL60, even though they are capable of outputting NTSC native signals. When switched to output true NTSC to an NTSC capable multi-format player, the NTSC image is just as poor as an US NTSC player.
