auto->720p does nothing?

[question]

Im trying to convert a 1600x900 video into 720p for youtube but the option seems to do absolutely nothing...video resolution doesnt change at all. What gives?

[zakk]

What codec do you use ?

[Jan Gruuthuse]

Close avidemux: open avidemux: load video. Avidemux looks like LoadVideo screenshot.
From menu: Auto: 720p, set aspect ratio as required if asked 4:3 / 16:9 / 1:1
Avidemux should now look like SaveVideo screenshot.
Check in filters. Active Filters: swsResize: swscale Resize : .... x .... => 1280x720, algo 1
Save Video. That should be it.

Just to add to Jan's response.

Each one of these auto options, runs a small script.
These scripts change the default encoding settings of Avidemux to suit the selected auto definition.
Some are:  setting the output container (muxer) and setting a display resolution (via the resampling filter) etc.

You probably will not notice any changes in the video display screens of avidemux.

[question]

Well usually absolutely nothing happens when i click auto->720p...

This time round i got a popup saying TinyPy:Exception, Exception:

And that was it. Thats without touching any of the settings, just loading the video and clicking on auto->720p.

Not sure what you mean by codec?

Upgraded avidemux, got this error : http://i.imgur.com/JJjpYk7.png

It might be usefull to provide more information about this video file.
Mediainfo is a free utility that will analyse media files and provide such details.
Its very easy to use. You get it here:

It looks broken indeed

[question]

It looks like one of the scripts in avidemux is failing (line 17)

Tinypy scripts like those found under the auto menu do work at least on windows 7.

Whenever executing a second tinypy script, Avidemux 2.6 will crash.
Probably the only time you would want to run another project script is when you close and reload a new video.
If so, you will need to exit and restart avidemux.

[question]

Huh? Im not trying to run a second script at all. Like i said i open the video, auto->720p then get that error message. For 2.6.8 64 bit.

[mean]

Confirmed, something is broken

[AQUAR]

@ question

I was merely describing my own experience with running Tinypy scripts, under windows 7 (x86 & X64) and with the latest avidemux revision.
This for the benefit of others who are trying to use this function.

Mean is the developer of this program, and he has already indicated something is broken with the scripting engine.
Since there is a problem we simply first need to wait for a fix.

If there is still an issue afterwards, we would look at your media source and see if that breaks the auto script in someway.

[question]

Oh, ok. How do i convert to 720p in the meantime then?

[Jan Gruuthuse]

Load video and run from Menu: File: Tinypy Project: Run Project: and browse to unpacked content of zip (720p.py). Video part should be set by this settings file.
