Recommend batch video converter with auto resize, fps, and a/v sync?

Are there any video converters out there that does batch conversion which:

A. automatically resizes video to fit within a specified resolution (320x240 in my case) while keeping the proper aspect ratio of the original file (e.g. 2.35:1 aspect ratio movie file would be resized to 320x136 although the max resolution would be specified as 320x240)

B. automatically retains the original file's frames per second

C. automatically correct a/v sync issues (i.e. detects if VBR, and converts to CBR if necessary... or however else it may be fixed)

?

I've been using 2 programs mainly, but each have their pros and cons:

1. Creative Zen converter
Pros:
- Does A and C
Cons:
- Does not do B
- WOEFULLY SLOW

2. SUPER
Pros:
- Fast
- Using mencoder option appears to do C (ffmpeg option does not)
Cons:
- Does not seem to have ability to do A or B for multiple/batch files (but will do them if I specify the parameters for each individual file which of course will take up some sweet time as I use GSpot to determine the original frames per second and the proper resolution that will retain the aspect ratio for each file)

It would seem to me that if SUPER somehow implemented the options for "retain original aspect ratio", "retain original FPS", and automatically detected VBR a/v and corrected it, it would be my weapon of choice. But sadly it does not (at least not that I know of). Are there any alternatives out there that does?

I'm basically wanting to convert higher resolution divx/xvid, mp3/ac3/aac, videos to fit my 320x240 Zen (or possibly a new PMP with different resolution) in xvid-mp3 video format with the above mentioned capabilities.

 

I think Super would do the job -just put your frames to 30 per second - if you have less in the original file it won't be a problem, if you have more it wont really matter as you wouldn't see the difference.

About the aspect ratio - have you actively tried?
I think Super would either add black bars or create an odd ratio - I can't imagine the software stretching or squashing images...

 

I'll try that with the frames.

As for the aspect ratio, SUPER doesn't retain the original aspect ratio. By selecting 320x240 resolution, SUPER changes the original 2.35:1 AR to 4:3 making it taller and filling the entire Zen screen without the black horizontal bars above and below the video (which would be there if I selected 320x136 resolution).

 

hmmm...that's bad...

 

AVI DeMux might work for you. It has the ability to batch. But if the goal is display on a 320X240 screen, don't you need to letterbox, and not crop?

 

Cropping? My previous posts mentioned no such thing. The Creative Zen converter will properly letter box the video whereas SUPER will only letterbox it if I input the letterbox resolution (e.g. 320x136 for a 2.35:1 AR video... which would be fine if all my videos shared the same AR, but they don't). Selecting 320x240 on SUPER will stretch the original video, not crop it.

Thanks for the program suggestion. Any more?

 

have you checked whether the functions you are after is availible in virtualdub?

edit: I used virtualdub to convert DivX movies to be able to watch them on my Sony Ericsson mobile phone. VirtualDub has all the features you're looking for, with the possible(!) exception of automaticly fixing out-of-sync problems, though they can be fixed manually.

 

I used mediaconverter to batch convert a bunch of aviation documentary, it work extremely well and is free too and you can also select a pre-configured profile for different devices if you have no idea of what you are doing....

 

I mainly use virtualdub for fixing a/v sync errors. It's pretty slow and I haven't figured how to do batch conversions with it.

For a second, I thought mediaconverter was the same as mediacoder. I'll check it out.

 

Hi Ayle,

Isn't "Media Converter" an "Online" Freeware Service!?!?

I tend to be hesitant when I have to rely on the "Online" service!

G!

 

Nope it's not. It works perfectly offline. Where did you hear that it was online only?

 

Good to know. I figured it probably would stretch the video to fit and was suggesting encoding at 320X240 with the bars built in.

 

MediaCoder works pretty well for video conversion, I've used it for a few years now. Main problem I've had with it is sometimes new builds won't work for what I need it to do at all.

But you're good once you find the latest one that works.
