Another alternative:

My small GP2X Video Converter:
http://dl.openhandhelds.org/cgi-bin/gp2x.cgi?0,0,0,0,15,2297



Converted movies/videos are perfectly playable on Dingoo.

btw. dont let this screen fool you, its windows app, not gp2x app :)

Tried your converter but i find handbrake easy and better (keep same aspect of original source) tried 2 more video converters and a gui for ffmpeg!

So far handbrake converts so much faster.

Only problem with handbrake is the video out puts are only MP4 (MPEG4 Video) and AAC Audio, or M4V (H.264 Video).

for some reason in Handbrake i cant get it to out put Mp3, i select option but out file has no sound.

I guess Handbrake will do the job, because

a) MP4 still plays on Dingoo so does not matter that its not Xvid/AVI
b) AAC Audio at 128br sounds as good as originals MP3 at 141br
c) It can reduce exactly 50% video screen size, i.e 624X352 when set to output to 320X240 will output 312X176 which is 50% of original size if i keep Aspect Ratio option selected.

Other converters out pit to 320-240 and the video looks stretched, but if i force 16-9 aspect in my PC Video player it looks same as handbreakes 16-9 312X176 file.

So i guess even if i found a program that keeps the same Video/Audio Codecs i.e Xvid/Mp3 and converts to 320X180 (keeping aspect ratio). Then i guess whats the difference if Handbrake does the job fast (2min) but outputs a MP4 with AAC that looks and sounds the same.

Update....

I downloaded a older handbrake ver 0.93 that has Xvid/AVI support.

I converted a video 624X352 to Xvid/AVI MP3 Audio 312X176 VBR 300, 128ABR file = 73MB

did same again but with MPEG4/MP4 and ACCC Audio 312X176 VBR 300, 128ABR file = 71MB

Both videos look near identical on Pc even when zoomed to 200%

The AVI took more time than the MP4, so i guess the smaller size 3% saving, and faster encode 25% faster maybe the MP4 format is best used for fast results.

I am going to try mess about with a 200VBR and 96ABR that should output about a 50MB File which is going to be good enough for Dingoo

For my Dingoo (native OS) I use this: http://www.any-video-converter.com/download-avc-free.php
I use MPEG-II codec with this settings: resolution: 720x480, 1800 bitrate, audio codec: [email protected] 384 kbps and sample rate 44100. For me it's ideal.

That will result in video files that are really very very extremely large. Use Avidemux (Linux) or flaskmpeg/Virtualbub (Windows) to reate an AVI => [email protected] kbps + [email protected] kbps.
Finally got me a new Dingoo after I Kentucky ~~::fried::~~ the other one. Yippee! [edit] And lost it!

I found out that that due to the low screen size of the Dingoo and if your not planning to use TV Out.

Then re-encoding a Video upto 320X240 (or simular) with VBR of 200-300 and ABR of 96-112 gives good results and also smaller file size (1/3rd) so you can get 3X more on the SD Card.

You dont notice the loss in quality much with Video because of the small screen and how the Dingoo does not duplicate the quality of higher VBR well anyway. And the Dingoos speakers are not great so you wont tell a 96-112 ABR compared to say 140-160 ABR

Give it a go (i use Handbrake) take a video file say 640X Res and shrink it to 320X with 1/3rd VBR and ABR of 96-112.

Use your PC media software to play both videos side by side but set it to display the original 640X video at 50%, both videos will apear the same size on your screen (windowed) you will see not much difference in quality and you wont notice it much on Dingoo.

And you can by doing the above get a 700MB File down to about 250-280MB, a 175MB Cartoon down to 60-70MB

A 2 minutes and 30 seconds video occupies 40 MB, which seams resonable for me :).

You're joking, right? A 2:30 minute video being 40MB is not reasonable. That's horrible and unnecessary.

I think he may be joking  ;)

I took your advice, and indeed cartons like the The Cleveland Show when halved the resolution, with VBR 200, and ABR of 96 still look good on the Dingoo and saves space 48MB instead of 175MB that means all 21 season 1 episodes will only take up about 1GB space  :) and only take 1:40 secs to re-encode with Handbrake

So thanks for that advice Jesse Top Bloke 8)

I use these settings in AVC:

.AVI Profile
XVID codec
480x320
768 kbps (looks better than you think)
25 Frames per Second
MP3 Codec
128kbps
2 channel with basic sync

But im starting to think audio is going desync on longer videos (i still didnt test it on a long file), i probably should test later (damn AVC has that problem)

Well i have been messing about now with settings for a bit in Handbrake.

And found if i set the resolution to match within 320X240 with Audio Bitrate of 96-112 and set program to reduce files size to between 50-60% of Original file for most Movies/TV

If the Programs are Cartoons, especially simple ones like Family Guy/South Park then set Handbrake to output file size to say 30-40% of Original i get good results.

I have got South Parks and Family Guys looking good at a file size of 50-60MB each (i can get about 140 on a 8GB SD Card), Most movies i shrink to 400MB and so can get 19-20 on a 8GB SD Card.

People who do a lot of video editing and/or coding NEVER use weird commercial progs. Everybody ever made a good looking video for any system (PC, DVD, Playstation, Dingoo, mediacenter) always  used ye 'ol Virtualdub (Windows) or Avidemux (Linux). And those video's never get out of sync. Not even on the Dingoo.

And the settings that are always used are:  AVI => [email protected] kbps + [email protected] kbps. Believe me: you do not have to reinvent the wheel every time or discuss about it.  :-X

Yeah i know what you mean as far as whats best to make a video, i.e if you was ripping a DVD.

I was just saying that because the Dingoo does not support 32bit colour and only has a 320X240 Screen, videos you could play a Video at 640X and a re-encoded version at 320X and on the Dingoo you dont notice the difference really.

The only difference is when you change the video bitrate, which i do purely because on such a small screen a video with 900 VBR vs one with 300VBR is not that far off, compared to the saving in file size.

So i only use Handbrake purely to quickly change videos to a smaller screen size/bitrate so as to save 50% or more on the file size. I also find it good to use for re-encoding videos to MP4 for Mobile Phones or PSP's that do not play native DivX/Xvid.

And i get the whole purpose of my original post a while back was to find the best way to reduce the file size of videos with not so much trade of in quality and using software that can do the job fast. (Handbrake does a 175MB file to a 60MB in 2-3min, VDub in 3-4Min and a lot of those comersial converters can take like 20 mins).

So basicaly i can now get say 35 Family Guy Eposodes instead of just 11 on a 2GB Card.
