Resize without re-encoding?

[sinz718]

Is this possible and I don't mean to increase resolution from a poor quality video.

I want to downgrade from 1200 down to 720 is this possible?
Example:
Width : 1 280 pixels
Height : 544 pixels

to (just a ruff quick example)

Width : 720 pixels
Height : 288 pixels

I need to do this because I haven't updated my player and it only plays 720 pixels max and I wanted to know if I could alter a higher resolution to a lower resolution and have my player play the file say via .avs script or something within the container?

The container is .avi

Thanks

I didn't know there was a player with that limitation, which device are you playing on and what happens when playing a >720 file?

You can resize in Avisynth in real time with a simple:

Avisource("file.avi")
BicubicResize(720,288)

It is not possible to resize without reencoding.

Yet you can resize during playback, but this on the computer only.

Depending on the file format, you can define a viewing window (a part of the image that would be displayed).

Nevertheless, the resolutions you have are not standard and there are chances the files won't be played (or in a good quality) on certain standalone players.

It is hardware based divx player for home theater systems.
I guess the PC is just an all around better idea then fiddling with hardware to play a file.

Thanks gents for your help, this is now completed in full for me.
Decided to just re-encode the files to my divx players limitations.

Anamorphic support for MKV/AVI etc aside, I've never come across a MKV/MP4/AVI capable HD standalone player which can't play a 1280x544 video correctly. Which MKV/MP4/AVI capable players won't?

Well if the OP's cannot play >720 files at all I guess we found one. ;)

If he has a "DivX Player" chances are it is one of those old DVD players or similar that really didn't play anything but DVD, VCD and DivX/Xvid in AVI and nothing >SD resolution.

As Ghitulescu said it is not possible without re-encoding. The AviSynth script is just a text file. It needs the AviSynth software and plug-ins installed on a PC to be interpreted and actually do any processing. You cannot install AviSynth on a hardware player so it cannot do anything with the script.

When I offered the script I did not know the OP was even using a hardware player, I guess it should have been obvious due to the crazy restrictions but it wasn't mentioned. Of course on playback resizing isn't an option on a hardware player. :p

I used the description "MKV/MP4/AVI capable HD standalone player" somewhat deliberately..... ;)
The OP is using a DVD player.

I remember those days..... encoding everything twice so I also had a standard definition version the trusty old DVD player could play. Thankfully those days are gone. In fact I recently purged my media hard drive(s) of all those duplicate AVI SD copies to create some more free space.
