Cheers will try ;)

I will be looking to do the first 10-12 He-Han, Thundercats and also do some Simpsons, Family guy and others so i got good choice.

The Plane usually has good choice anyway.

Another Question is regarding Battery Length, roughly from Fully Charged how long would a Dingoo last for playing back Movies if i have it set to 3/66% Brightness, using headphones.

I was thinking of getting one of those USB chargers that you place AAA batteries into and it charges any device that charges via USB (in case Battery goes flat).

Also what size SD Cards can a Dingoo go upto? I was thinking of getting 2X4GB and 2X8GB (micro/TF with the Mini Adaptor).

I am also thinking of getting a 2nd Dingoo but a white one this week.

I may try using aac and lowering the audio bitrate myself. But that's a lot of videos to re-encode. I might do it. Maybe... *sniff*... maybe.

I actually use the lowest brightness setting in native. How can you stand having it any higher? :P

Some Dingoos have smaller batteries than others. But either way I have no idea how long it would last from just watching videos at your brightness setting. There's only one way you can be sure. ;)

Well I know at least 16GB cards work. I think any size card should work, but I don't really know. It would suck to buy a $60 32GB card only to have it not work on the Dingoo for some reason. :( But if you are only getting 4/8 GB ones then you have nothing to worry about.

Yeah i think my aim would be to have  2 Cards for Emulation/Homebrew and Ports (inc Dingux on each)

Then 2 Cards one for TV/Cartoons and other for Movies.

More than one card is way too much effort and un-necessary, I just stick with my 2GiB card and the 4GiB internal flash. It can fit more than enough films/roms/games on it to entertain me and leave room for development stuff.

Lol, too much effort? Oookay.

Maybe 6GB is enough for you, but not for me. Even though I barely use the thing, I feel the need to keep every NES, SNES, GB/C, Megadrive, SMS, Gamegear, Atari, and Lynx games on it. Also dozens and dozens of GBA and arcade games. Plus most of the various ports and games like Doom. And a selection of MP3s and videos. I'm using around 14GB total at the moment. :P

Well i have 3X 8GB Cards...

One will be for Movies and TV etc, i find reducing a 700MB file to 350-400, depending on movie (i.e if a dark film then 400, if a animated etc then 350) TV shows from 350MB to 175-200, and Cartoons etc 175MB down to 75-100MB seem to give me decent enough quality.

a 8GB Card can hold about 16 hours video (620-640X res 900-1000 VBR) which is average Xvid/Divx quality.

So if i recode then videos i can then get 32-35 hours on a card.

As for CPS1, SNES, NES, SMD, SMS/GG, PCE they dont take up much space.

GBA/CPS2/MVS take up the most.

One Card will have ports on such as Doom and its mods, and also Open BOR etc....

Since my personal rips and most of the rips you find are already encoded with MP3, it would be a poor thing to transcode them to AAC. For a bit I was wondering why this 112kb MP3 transcode was sounding much better than this 112kb AAC transcode, and that's why. Pay attention to what the original file was compressed with.

I tried using an average video bitrate of 350 like you did, dave. You can clearly see the difference if you blow up the image, but if you leave it at it's intended size then I see little point in going above 175~225. The amount of quality gained doesn't justify the amount of space used. Especially for those very simple, very low motion cartoons where 175 already looks nearly pristine. Obviously more detailed, higher motion cartoons will need to be higher. But I haven't had that problem yet. I don't see how the typical South Park episode could require that much space. Isn't that what you tested with? South Park? Maybe it has something to do with me using Cartoon Mode with Xvid?

To repeat, for simple looking cartoons I use 320x240 two pass MPEG-4 ASP (Xvid) at the default settings (except Cartoon Mode is enabled) with an average video bitrate of 175kb and 128kb CBR MP3 audio in an AVI container.

Also, I am now using avidemux instead of virtualdub for my transcoding. It seems to do everything I used virtualdub for; plus you can render to other containers beside AVI without mods and experimental builds and command line BS. Seems simpler.

So concludes another annoying newbie video encoding ramble in this thread.

Well what do you reconmend...

As Super @ does not install i get cant download files error when running set up, so i got 2 older versions and they dont look that simple as far as lay out and options (handbrake is easier) and when i click encode the program exits.

Only Problem i have with Handbrake is it only has X264 or MPEG4 as codecs with extentions m4v/mp4.

The other one is i use the default audio setting which outputs to AAC just ajust bitrate, as i i select Mp3 i get no sound at all.

Other programs i have tried are slow, PSP Video, AVS Video Converter all take like 30 mins+ to encode a 350MB 640X (900BR) Video down to 320X (300BR/ or 175MB) where as Handbrake takes about 3 mins if that.

As far as Movies go i intend to not shrink movies that have dark scenes as much, but shrink ones with light more as compression is not as noticable on light scenes.

For Cartoons as you said a  Family Guy/Simpsons/South Park have not much detail (the Drawings are not hard to do and colours not vibrant) so they can get reduced to like 60MB and look ok, but some with more detail in them like say the new He-Men or say detail the Latter Disneys have i would shrink to 75MB

What Program do you reconmend thats also fast!

Someone already did mention Format Factory. I tested it and it is ok. Give it a try.

Did you try the one I recently mentioned? Avidemux?

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: mp2@ 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 => Dix@800-1000 kbps + mp3@128-192 kbps.
Finally got me a new Dingoo after I Kentucky ~~::fried::~~ the other one. Yippee! [edit] And lost it!
